Types of malfunctions of a two-chamber refrigerator Atlant

Potential minor issues

More often than not, problems arise that you can deal with on your own. To get rid of them, you don’t need any special tools or complicated actions, but sometimes you can’t do without a specialist.

Alarming sounds

Equipment in good condition works smoothly and does not “delight” the ears of the owners with incomprehensible sounds. If the Atlant refrigerator starts to make noise, then the anomaly indicates a problem.

1. Vibrates, knocks. This reaction of the refrigerator is often caused by incorrect - cramped - arrangement of products or an uneven floor. Loose compressor housing shock absorber fasteners must be tightened. The noise from behind is caused by pipelines. They can be bent or a sealant can be placed. A metallic knock when the unit is turned on requires the intervention of a technician, as it can be caused by a compressor malfunction.
2. It buzzes, then clicks sharply. The reason is the failure of the compressor protection - the starting relay. It is replaced at service centers.
3. Howls, gurgles. This is a natural and short-term phenomenon, as it is caused by intense movement of the refrigerant.
4. Whistles, hisses. Probable causes are a foreign object in the capillary tubes, debris that has “managed” to get on the fan blades, or problems with the compressor. In the latter case, professional help is needed.
5. It creaks and crackles. The electric motor is to blame for the sounds, on the verge of life and death. In refrigerators equipped with a “No Frost” system, the problem is often that defrosting is rare: the fan blades begin to touch the ice. Slight cracking due to large temperature differences is caused by plastic walls. The unit makes dissatisfied creaking sounds when it is installed incorrectly - too close to the wall and other furnishings.

Not frozen hard enough

Chronic lack of cold air is associated with several factors.

1. With the thermostat - its incorrect position or malfunction. The first can be eliminated by reading the instructions for the Atlant refrigerator. A breakdown is a reason to contact a workshop for a replacement.
2. With a sealing system that gradually loses elasticity. To restore the unit's tightness, you should try to re-hang the doors. If the procedure does not help, the seal must be replaced.
3. With a leak in the freon circuit - a refrigerant leak. They find the localization of the problem with the help of soap foam, but it is better for a specialist to fix it.
4. With a broken control board, clogged capillary tube, or defective motor. These problems also cannot be solved on your own.

Water, water, all around and everywhere

Among Atlant refrigerator malfunctions, troubles of this kind are not uncommon, but here it is no exception, since similar natural “floods” occur in other brands. The drainage channel in the refrigerator compartment is usually clogged. Such a problem can be easily eliminated with your own hands. Use wire or blow with a rubber bulb. With it, filled with hot water, after removing the blockage, the hole is washed.

There are other reasons for the accumulation of “water resources”:

• a disconnected water pipe causes water to leak from the drain hole onto the floor;
• The thermostat is not working correctly and needs to be replaced;
• malfunction in the “No Frost” defrosting system.

To avoid potential troubles, it is necessary to regularly check the water tank, as the material can crack over time.

Trouble with light bulbs

When the lamp inside the refrigeration chamber does not light, it must be replaced after it has expired. There are other reasons - a breakdown of the plastic pusher that controls the lighting, or a break in the electrical circuit. They require the help of a master.

The red light is an indicator; it warns of violations of operating conditions, usually of temperature conditions. Common triggers for switching on are a lack of tightness due to a poor-quality seal, the door being open for a long time, or placing a large amount of warm food in the chamber.

The indicator can signal serious problems with the system - stoppage of the compressor, breakdown of the control unit, temperature sensors, freon leak. These cases are a reason to contact the service.

Appearance of the first snow

An anomalous “natural” phenomenon is observed on the wall of the refrigerator compartment. Leads to it:

• incorrectly set temperature;
• skimping on operating rules;
• failure of the evaporator heater, freon leak.

By changing the position of the thermostat to a lower number, it is easy to get rid of snow. It is not recommended to keep the refrigerator door open for a long time, especially in the heat, or to place hot foods in the chamber.

Why does the engine stall?

When your Indesit, Atlant or Nord refrigerator has stopped freezing, but in the main compartment the light or LED backlight is on (or not on), first check the following points:

If you have new equipment, packed with modern features, and they all work, but the camera is warm, check that the installation is correct. If the position of the cabinet is uneven and you did not use a technical level during installation, the door may not fit tightly. The “smart” model will not allow the motor to turn on if warm air enters the chamber. There is no point in cooling the air - its supply does not stop. Some models will inform the user about the problem by displaying the corresponding error code on the electronic display.

If you have a Biryusa refrigerator and the light does not light in it (as well as ZIL, Dnepr and any old model), pay attention to the power cord, plug or socket. Perhaps the technology is not “to blame”, and the root of the problem lies on the surface

If the electrical component is in perfect order, the old refrigerator could have failed due to an internal problem. Turn off the power to the equipment, unload the shelves and wait for the technician.

What to do if the light does not come on and the motor does not work:

1. Reboot the refrigerator.
2. If the compressor turns on but the light does not come on, inspect the light bulb.
3. If it is burnt out, replace it.
4. It is easy to replace a halogen, fluorescent or incandescent lamp yourself - remove the lampshade and reinstall the lamp.
5. If you need to change the LED lamp, proceed carefully or contact service.

It is worth considering in more detail the reasons why the device refuses to work. Narrow down the range of possible breakdowns by reading our table of possible failures, causes and symptoms:

When an imported or domestic refrigerator does not work (for example, “Stinol”), and the light is on, you should pay special attention to additional “symptoms” of the problem. Don't ignore clicks and other signs

All of them will help the technician in the initial diagnosis of the problem.

Sometimes failures occur due to force majeure. For example, an air sensor can burn out due to a power surge. And along with it, the light bulb may burn out. Therefore, the absence of light is not always an accurate indicator of a breakdown.

When you can't do without a master

It is required to entrust the work to specialists if the following circumstances arise:

• It is necessary to disassemble the housing.
• It is necessary to check the performance of the compressor.
• Control requires a thermal relay or freon.

Only a professional will be able to competently handle condition assessment and repair work regarding electrical wiring and the electronic control unit.

Shortened refrigeration cycle

The main failures and problems in this direction can be described as follows:

1. Only 1 working cycle per 1 hour.
2. Repeated turning on and off of the compressor within 1 hour.

In the first situation, the equipment faces increased downtime. The evaporator has time to thaw, which leads to the formation of ice on the walls. In other situations, the motor consumes too much energy, resulting in waste. Finally, the food in the chamber is frozen when the operating period of the device is longer than the rest period.

It is better to study the technical documentation in advance, since each manufacturer has its own indicators in this direction, as well as its own compressor mechanism.

The total duration of the refrigerator operating cycle, which is associated with continuous cooling, depends on the following features:

• Freon brand.
• Device performance level.
• Congestion in the internal space.
• The temperature of the products placed in the chamber.

If you notice that the refrigerator does not turn off for 12 hours or more, you need to check how it works. This often happens when running some programs. If the Atlant refrigerator does not work, you should call a technician.

Malfunctions of the motor-compressor

Note. The room temperature and the position of the control knob are what you need to check if the equipment has been operating for a long time without interruptions. Subject to compliance with standards and regulations, the initial diagnosis begins.

Sometimes breakdowns occur due to a thermostat that has failed in the Atlant refrigerator.

Freon leaks lead to the fact that frost does not form on the walls, the result is many different malfunctions in the equipment.

Repairing the thermostat requires following the following instructions:

1. Removing the door.
2. Removing the plugs and unscrewing the bolts holding the top cover.
3. Removing the top panel.
4. Unscrewing the thermostat fasteners.
5. The part is removed and replaced with a new one.
6. Assemble the body.

Sometimes the cooling system of the Atlant refrigerator also needs to be opened to check the internal parts. After all, freon leakage negatively affects the operation and service life of other parts. If the amount of freon inside is normal, then there is a high probability of the tubes being clogged. If necessary, structures are examined for damage, then they are simply repaired by welding. In most cases, the freon in the circuit requires replacement. Malfunctions of the Atlant refrigerator and their repair do not take much time.

Rapid accumulation of snow “coat” on the back of the device

There are many reasons why this particular malfunction occurs:

• Operation of equipment in low productivity mode.
• Storing hot food inside.
• Increasing room temperature.
• The door does not fit tightly enough to the body. Single-compressor models may also encounter this problem.

Interesting. It is the last point that should be checked first if problems that belong to this group arise during operation. Another common situation is that the refrigerator is located in a fairly warm room, which is why it does not operate at full capacity. The problem should be resolved immediately after setting the required parameter.

The refrigerator body is electrocuted

It is not recommended to deal with the problem yourself if even the slightest touch produces a damaging electrical discharge. The likely problem is the contact between metal walls and wires. The specialist finds out which place was damaged in order to then isolate it from the main part of the equipment. And carry out high-quality repairs of the Atlant refrigerator.

How to deal with typical Atlant refrigerator malfunctions?

There are minor damages that you can fix. But if replacement of parts or assemblies is required, then spare parts for Atlant refrigerators must be original. The photo shows factory components for the refrigeration unit. It is better to entrust such work to a highly qualified specialist. He will also be able to change the Atlant refrigerator relay if it does not work.

The main faults are:

• The refrigerator is connected to the network, but does not work, the light in the refrigerator compartment does not light. This can happen for two reasons: there is no voltage or there is no contact between the socket and the plug of the device. First you should check if there is voltage in the network. To do this, plug in any working electrical appliance into a power outlet. If this does not help, then good contact between the plug and the socket is necessary.
• If the refrigeration unit is working, but the light bulb inside does not light up, then it is most likely burnt out. You will need to take a working lamp and replace the burnt one. To do this, unscrew the screw, remove the lampshade, change the lamp, return the lampshade to its place and tighten the screw.
• The refrigerator works, but is very noisy. This problem occurs if the device is not installed correctly.

The cooling temperature in the chambers is not low enough, which means the door is not closed tightly. To adjust the temperature, close the door tightly.

Determining Atlant breakdowns that require calling a technician

In addition to the classic malfunctions of Atlant refrigerators, there is a separate category of problems that are not recommended to be fixed on your own. Often, when trying to repair, a person receives a completely faulty unit that requires large investments, so the best option is to independently diagnose and call a specialist from a service center (service center).

Non-stop compressor operation

When the Atlant refrigerator motor is running non-stop, first of all you need to carefully review the instructions for the presence of a super-freezing mode and the possibility of turning it off - with this setting, the refrigerator may not turn off the compressor for 12-14 hours in a row. In older models, weak pressure on the thermostat sensor may also be observed - if the thermostat mounting bar is loosened, the motor will also operate in “non stop” mode. The following possible breakdowns may lead to the need to call a technician:

• capillary tube clogged;
• refrigerant leak from the system;
• thermal relay malfunction;
• breakdown of the pressure circuit on the thermostat.

Attention! The only fault from those listed that you can safely approach on your own is replacing the thermostat, but despite the simplicity of such repairs, for the first 1.5-2 weeks you need to carefully monitor the operation of the refrigerator and, if necessary, call a household appliance repairman.

Shortened motor cycle

If the motor starts only for short periods with a short break between starts, first of all you need to check the voltage in the network and possible interruptions - if the power supply is not normal, you need to install a voltage stabilizer. In another situation, you should check the condition of the starting relay - often it simply requires replacement. In cases where replacing the relay and installing a stabilizer does not help, it is necessary to check the condition of the compressor - for this it is recommended to simply call a specialist.

The body conducts voltage and experiences current

When the Atlant refrigerator receives electric shock from the body or other parts, you need to disconnect the unit from the network and call a repairman. There is only one reason for this strangeness - a breakdown of the electrical wiring inside the refrigeration unit. If the wire insulation is damaged, it is difficult to identify the problem yourself - you need specific knowledge of electrical engineering and the design of the refrigeration unit.

The refrigerator stopped working after defrosting.

The usual procedure can have serious consequences. Defrosting is no exception. Do not break the ice with sharp objects, as this may damage the internal appliances and the refrigerant circulation system. But even after full compliance with the requirements (the appliance was unplugged, thoroughly washed, wiped and dried), a snag may arise - the freezer does not turn on:

• The cause may be mechanical damage to the freon distillation system through tubes. Methane liquid is called freon; it is thanks to it that food freezes. With this outcome, the liquid flows out, and instead of it, ordinary air passes through the pipes, which causes overheating.
• Freon circulation is disrupted due to clogged tubes. The reason may be inaccurate cleaning, washing, and spontaneous formation of blockages as a result of defrosting should not be ruled out. To eliminate this, a compressor pump is required. It’s better not to take on the problem yourself. We contact the service to get help from a specialist.

Two-chamber Atlant

Are you the owner of an Atlant two-chamber refrigerator? Great. Have you noticed any problems with his work before? Fabulous. But today your single-compressor or double-compressor refrigerator began to work incorrectly? Doesn't turn off, ice freezes inside? Let's figure out what the reason is. But first, let's look at the correct mode of operation.

Two-chamber Atlant

Correct operating mode The refrigerator motor should run intermittently. This is necessary to provide it with time to cool down. The duration of the working period and the time in the off state varies depending on the selected temperature of the internal chambers of the refrigerator. For an Atlant refrigerator, the norm may be long-term engine operation with intensive cooling and freezing. Try changing the mode. If after this the refrigerator continues to work continuously and does not turn off, it is worth considering other reasons.

Evaporation system and compressor

The Atlant two-chamber refrigerator may have different malfunctions. Refrigerator not working? This may happen due to a leak. This usually occurs when cracks appear in aluminum or copper pipes. Freon enters through the tubes and exits through the holes. Because of this, cold does not form. As a result, the pressure in the compressor has a negative impact on the operation of the device as a whole. This causes wear and tear on the equipment. Cracks form in the old appliance.

Simple problems

The origin of damage to the refrigeration compartment is different: from a lack of electricity in the network to a compressor breakdown.

Analysis of finding the cause of problems begins with checking the presence of:

• connecting the refrigerator to the network;
• working wires, extension cords and sockets;
• electric current.

The absence of cold is possible due to the long operating time of the unit without defrosting.

The problem can be easily resolved:

• turn off the refrigerator;
• a day after defrosting, they turn it on again.

When the freezer is densely filled with food, the compressor power is spent on freezing and is not enough for other cold compartments.

The detectors send signals to the compressor to increase power, but the refrigerator does not cool down. This happens if the freezer is located inside the unit.

This problem is easy to fix:

• prolonged defrosting of the refrigerator;
• installation away from heat sources;
• turning on in standard mode.

Malfunctions from the category of extremely serious

This is the category of problems that it is better for amateurs not to try to “fix” themselves; usually they get the opposite result of what was expected - the refrigerator fails forever. The only thing the owners can do is determine the nature of the breakdown.

Non-stop operation of the refrigerator

Such consequences are caused by unidentified malfunctions in time - a refrigerant leak or a clogged capillary tube. Both problems are the reasons why the Atlant refrigerator compressor has turned into a perpetual motion machine.

The blame for the first trouble lies with careless owners who damage the channel with various piercing and cutting objects due to the desire to quickly defrost the freezer compartment. If there is a shortage of freon, the circuit is charged with refrigerant and leakage is prevented.

If a lack of gas is not detected, a blockage is diagnosed. The reason for this is the “clogged” type of freon. It is characterized by “coming into contact” with motor oil; because of this misalliance, a blood clot appears in the system. It is eliminated by blowing out the capillary tube. The clot-interference moves into the evaporator and ends up on the drying filter.

Indecently short cycle time

First of all, check the network voltage. If interruptions are detected, purchase a stabilizer. When the power supply is normal, the thermal relay is removed and the electric motor is connected directly. If the unit starts to work normally, change the relay. Other diagnoses are motor jamming, compressor winding breakage. Their “treatment” will be expensive.

Atlanta thermostat failure

This is the “sin” of most former Minsk models. Typical symptoms of a thermostat “disease” are a refrigerator that does not want to turn on or off, freezing of food stored in the refrigerator compartment.

More often than not, this device in models is located outside the refrigeration chamber, so serious work remains:

• remove the door;
• remove the plugs on the cover and unscrew the screws;
• remove the panel, remove the thermostat by unscrewing the screws securing the brackets.

After replacing the device, the refrigerator is assembled. In those two-chamber models where the freezer compartment is located on top, the thermostat is located on the back wall of the refrigerator.

Atlas, easily electrocuted

Even a not very powerful discharge of current when touching the device is a sufficient reason to call an emergency technician. If such a problem occurs, there are bare wires inside that are in direct contact with the walls. You cannot fix the malfunction on your own; only the refrigerator can quickly find the dangerous place and insulate the wires.

Reasons for contacting the service center

Diagnostics and repair of refrigeration equipment should definitely be entrusted to the refrigeration specialist if it is necessary to disassemble the circuit, check the functionality of the compressor, thermal relay and the presence of freon. Assessing the condition and repairing electrical wiring and electronic control units is a task for professionals.

Reason #1. Quick shutdown of the refrigerator

To determine the possible cause of the shortened operating cycle, it is necessary to analyze the sound when the unit is turned on/off.

To diagnose the problem yourself, you can do the following:

1. Check the mains voltage.
2. If the indicator is within the normal range, then you need to remove the thermal relay, and then connect the motor directly.
3. If the unit is working properly, then the cause of the shortened cycle has been identified. The next step is to replace the thermal relay.

If the cyclical operation is caused by fluctuations in the power supply, then the installation of an alternating voltage stabilizer is required. More serious breakdowns include rupture of the compressor windings or jamming of the motor. Fixing a malfunction or completely replacing a defective unit will not be cheap.

To replace the start-protection and thermal relays, which are a single unit in household refrigerators, it is better to contact a workshop. However, it is quite possible to do the work yourself, based on the information presented in the video:

Reason #2. Damage to external and internal thermostats

In most Atlant models, the thermostat is located outside the refrigerator compartment - under the top cover. Replacement of the element should be entrusted to professionals.

For your information, here is the general operating procedure:

1. Remove the refrigerator door.
2. Remove the plugs on the cover and unscrew the screws.
3. Remove the top panel.
4. Unscrew the screws that secure the thermostat brackets, remove and replace the element.
5. Reassemble in reverse order.

In two-chamber versions with a top freezer, the thermostat is located inside the refrigerator - the bellows tube is attached to the rear wall of the unit.

Reason #3. Current breakdown on the refrigerator body

If even a light touch to the case is accompanied by at least a slight discharge of electricity, then it is highly not recommended to find out the cause and fix the malfunction yourself. It is likely that exposed wires are in contact with metal walls. The refrigerator will identify the damaged area and isolate the problem area.

Reason #4. Clogged capillary tube and freon leak

Both malfunctions lead to similar consequences: an increase in temperature inside the refrigerator compartment and continuous operation of the motor-compressor. To establish an accurate “diagnosis”, the wizard performs diagnostics - opens the system.

If the gas is in sufficient quantity, then a blockage of the capillary pipeline is determined.

Ways to fix the problem:

• pressing with a press – oil under pressure acts on the blockage;
• washing with a specialized solution similar to a “liquid desiccant”;
• blowing with compressed nitrogen;
• complete replacement of the capillary circuit.

If the Atlant refrigerator has stopped cooling and is not working due to a lack of refrigerant, the circuit will need to be filled with freon, the rules for which are described in detail in the article we recommend.

Freon leakage often occurs due to the fault of users. The most common reason is damage to the channel by sharp mechanical objects when defrosting the freezer or evaporator.

This video will show you one of the options for determining a breakdown, identifying a leak, how to fix it and the process of pumping freon:

Other

If the above breakdowns are not detected, and after defrosting the refrigerator continues to operate incorrectly, you need to check the device for rare malfunctions.

Magnetic valve stuck

In single-compressor refrigerators, this part operates in modes of alternating or simultaneous cooling of compartments. The valve may remain in a position that only cools the freezer compartment. With such a malfunction, the temperature of the refrigeration compartment begins to rise. The magnetic valve cannot be repaired; it is recommended to replace it.

Compressor fault

If the freezer or refrigeration compartment in a two-compressor device does not work, you should look for the reasons in the breakdown of one of the engines. Malfunctions occur due to improper operation of the device and voltage surges. The following signs indicate a breakdown:

• a thick layer of ice appears on the walls of the chambers (especially if the refrigerator is equipped with a No Frost system);
• the compressor is noisy, and the refrigerator does not freeze if there is no refrigerant leak;
• the device makes extraneous sounds - creaking, grinding, clicking;
• the compressor operates without interruption;
• The temperature in the freezer is much lower than normal.

It is difficult to fix a problem in an engine with your own hands; when replacing this part, you cannot do without the help of a specialist.

Inconsistency with climate class

Some refrigerators can be operated at elevated indoor temperatures. However, most Atlant brand devices are intended for operation under normal conditions. As the air temperature rises, users may notice that the refrigerator is not cooling food. It is also a mistake to set the intensive mode in the summer. In hot weather, you need to choose medium cooling levels.

Serious problems

If the Atlas malfunction is associated with a compressor failure, freon leak, or failure of the temperature sensor, the repair should be entrusted to a specialist.

Quick shutdown of the refrigerator

Common reasons for this failure are:

• Damage to the thermal relay or motor. If the refrigerator was running for no more than a minute and a popping noise appeared before stopping, you need to evaluate the condition of the compressor.
• Burnout of electronic unit modules. The malfunction is caused by voltage instability or operation of the device at high air humidity.

Troubleshooting begins by checking the voltage in the outlet. After this, remove the temperature sensor and turn on the motor. If the engine is functioning normally, the cause of the failure has been found. If the Atlant refrigerator does not work, the temperature sensor needs to be replaced. If a decrease in the operating time of the compressor is caused by voltage fluctuations, install a stabilizer. If the motor winding breaks, you need to contact a specialist.

Damage to external and internal thermostats

If the refrigerator suddenly stops working and the compressor does not turn on, you need to replace the thermostat. The part is located at the top of the device. Repairs are carried out as follows:

• the door is dismantled;
• the top cover is removed (to do this, remove the plugs and unscrew the bolts);
• the top panel is dismantled;
• the thermostat mounts are unscrewed, the part is removed and replaced;
• The housing is being assembled.

Breakdown of current to the housing

If the user feels an electric discharge when touching the case, it is impossible to determine the cause and correct the breakdown with your own hands. Damaged wires may come into contact with some parts of the device. The technician will determine the location of the breakdown and replace the cable.

Clogged capillary tube and freon leak

These breakdowns contribute to an increase in temperature in the compartments and an increase in the duration of operation of the compressor. To identify the malfunction, it is necessary to open the cooling system. If the amount of freon remains normal, the pipes are clogged. The problem is eliminated by applying pressurized oil, purging with nitrogen, or completely replacing the capillary system. If the incorrect operation of the device is due to a refrigerant leak, it is necessary to find places where the tubes are damaged and solder them using a torch. After this, the freon in the circuit needs to be replaced.

Network instability

There may be a problem with the power source even if the light in the refrigerator is on.

Modern refrigerators, both imported and domestic, are designed for a certain voltage in the network, which may differ from what is actually supplied. In the event of differences or discrepancies, such units operate intermittently. Power surges can occur even if a neighbor is carrying out repair work using an electric drill. To dampen sudden changes in the network, it is best to connect expensive equipment through voltage stabilizers. This will maintain proper operation of the device and increase its service life.

How to define normal work?

An ideally functioning refrigerator should work for 10 to 15 minutes and rest for 25-30. The duty cycle coefficient is calculated as follows: the working time is divided by the “idle” time. For example, 10/25 = 0.4. The interval between 0.37 and 0.5 is normal. Any deviation (0.2 or 0.6) indicates problems. Correction requires the intervention of a master. Malfunctions of the Atlant refrigerator are often easy to fix, so it usually serves people for more than a decade.

Features of the operation of the refrigeration and freezer chambers

In order for everything to work without interruptions, you need to properly configure the Atlant refrigerator; the instructions will help with this. The main part of the equipment is the compressor, since it generates pressure, thanks to which the refrigerant moves towards the condenser. During this process, heat is generated, and you can verify this by touching the back of the device with your hand.

Then the freon passes through the tubes and is formed into a gas. It takes power to push the refrigerant. Then the freon enters the evaporator and begins to boil. The formed evaporator is considered cold.

It is in the freezer chamber that these tubes are located, and from here the cold flows to the rest of the equipment. If there is no cold in the freezer, then there will be no cold in the rest of the equipment. The refrigerant then enters the compressor, causing circulation. This is why the freezer has a low temperature when there is a malfunction.

What should I check?

It is necessary to properly configure the Atlant refrigerator. The instructions include important information on the operation of the equipment. To avoid damage to the device, you need to pay attention to the following factors:

• The refrigerator doors should be tightly closed, so you should remove everything that interferes with it;
• if the room is hot, then in the freezer you need to set the indicator to 2.5 (temperature about 16 degrees), and in the refrigerator - 2;
• When the “full no-frost” mode is set, the freezer fan may freeze, which is why the cold will not penetrate into the refrigerator compartment.

How to define normal work?

An ideally functioning refrigerator should work for 10 to 15 minutes and rest for 25-30. The duty cycle coefficient is calculated as follows: the working time is divided by the “idle” time. For example, 10/25 = 0.4. The interval between 0.37 and 0.5 is normal. Any deviation (0.2 or 0.6) indicates problems. Correction requires the intervention of a master.

Selection of defrosting element for a refrigerator with a No Frost system

Relatively recently, the concept of No Frost did not exist at all among craftsmen and consumers. But since the late 90s, units with such a defrosting system have become firmly established in our everyday life. Of course, they are not without their shortcomings, but their most important advantage is durability, and I think the increased noise and weathering of products can be somehow survived. The most important problem that exists in No Frost refrigerators is the failure of the freezer evaporator defrosting system; usually the heating element burns or the defrost sensor breaks.

Replacing the defrost sensor is not a problem, the main thing is to know what resistance it has and how to get to it. As for the heating element, everything is much more complicated here and this is connected not so much with replacing it, but with finding just such a heating element. At the moment, manufacturers produce a very large number of models and it is very difficult for a simple consumer who decided to change the defrost heating element with his own hands to understand the modifications of this spare part. Few people know that despite the fact that refrigerator models are Samsung or LG, etc. with the No Frost system, a large number are produced, only a few types of heating elements are installed on them, that is, in most cases they are interchangeable, and the difference between them is only that their wires are connected differently. This is exactly the case shown in the video below, I highly recommend watching it so that you can further understand what I will talk about.

Before talking about replacing the defrost heating element, I would like to point out the signs of its malfunction. Even if the masters don’t judge me too much, there are still a lot of questions about this on my YouTube channel

You could see how to get to the heating element to check it in the video above, I also showed there how to check the defrost heating element, I think I won’t focus on this anymore, but first of all I’ll tell you about what indicates a malfunction of the defrosting system

• The refrigerator compartment has stopped working → If the freezer in your refrigerator is shaking normally, and the cold in the refrigerator has disappeared, this indicates that ice has formed on the freezer evaporator
• The refrigerator turned off and does not turn on → This applies to any control system, be it electronic or mechanical. The fact is that until the temperature sensor of the freezing evaporator (defrost sensor) reaches the required temperature, the refrigerator will not turn on. In an electronic control system, this usually happens like this: the consumer turns on the refrigerator, it works either for about an hour or about 8 hours and turns off, and then it can turn on after two days. The defrost sensor may also be to blame for this behavior. In general, everything needs to be checked
• The freezer doesn’t freeze → It’s not for nothing that I put this point separately, many times I hear that in the No Frost refrigerator, food has disappeared in the freezer, but in the refrigerator everything seems to be fine - this also happens. The fact is that if the air duct to the refrigerator compartment is not frozen, then this behavior is quite possible; in general, this happens in some models. Again, you need to get to the freezer and look at the ice on the evaporator

I have listed the 3 most important signs that indicate that the defrost heating element has burned out. Now you can proceed to the question that worries many, namely how to choose a defrost heating element for your model. To do this, you need to look at what parameters this needs to be done.

Let me sum it up

In order to select a heating element to replace the original one, you just need to measure its width and height, and also pay attention to the configuration, that is, if it is U-shaped, then you need to take the U-shaped one. You don’t have to bother with power, the difference is small

Common reasons

If the freezer is working normally, but the air temperature in the refrigerator compartment is constantly rising, you need to look for faults in the main parts of the system.

The thermostat has failed

You need to check the serviceability of the thermostat if the Atlant refrigerator has stopped freezing and the following symptoms appear:

• long engine operation, no rest periods;
• freezing of a thick layer of ice on the walls of the freezer;
• spontaneous shutdown of the refrigerator, after which the device no longer turns on.

If the Atlant refrigerator does not freeze, you need to do the following:

• disconnect the device from the network by removing the plug from the socket;
• remove products and removable parts, leave the doors open for at least 12 hours;
• turn on the device and move the thermostat knob to the maximum freezing position;
• place a thermometer capable of recording low temperatures in the middle part of the main chamber;
• leave the refrigerator running empty for several hours;
• take out a thermometer and evaluate the readings (if the device shows too high a temperature, the temperature sensor must be removed from the housing, disconnected from the wires and replaced with a new one).

Refrigerant leak

Freon begins to be released into the surrounding space due to the appearance of holes in the walls of the cooling system tubes. The most common cause of a breakdown due to which the refrigerator does not freeze is damage to parts when manually removing ice. Oxidation of the metal, accompanied by the formation of rust, also contributes to the appearance of holes.

When the amount of refrigerant decreases, the operation of the compartment located at the greatest distance from the compressor is disrupted. If the freezer or main compartment does not work, you will have to seal the holes and replace the refrigerant. To perform the work you will need special equipment.

The sealing rubber is worn out

If the upper chamber of the Atlant refrigerator does not freeze, and the compressor is working properly, you need to pay attention to the condition of the sealing gasket. When the rubber wears out, warm air enters the chamber, causing the device to increase its cooling power. Sometimes ice prevents the door from closing properly, which is why the refrigerator does not freeze. Replacing the seal or repairing it helps solve the problem. The gap can be repaired with glue. The dried rubber is dismantled, soaked in boiling water and returned to its place.

The drain hole is clogged

This breakdown is typical for two-chamber devices with a drip defrosting system. When the gutter is clogged, water cannot be drained out, which causes ice to build up on the back wall and prevent the freezer from freezing. Turning off, defrosting and drying the unit helps solve the problem. The gutter must be cleaned with a toothpick or a special tool included with the device.

What do you need to know to establish the correct operation of the refrigeration unit yourself?

First of all, understand the structure of your Atlant refrigerator. The temperature is regulated using the thermostat knob. If you set it to “I”, this means setting the most minimal cooling. When the thermostat knob is set to “7”, the Atlant refrigerator will operate in maximum cooling mode. A o indicates that the device is turned off. Look at the photo to see what the thermostat looks like.

The thermostat knob should be set to one position or another, depending on the following factors:

• ambient temperature value;
• how many products are stored inside the unit;
• how often the door opens, etc.

If after this the cooling is insufficient, then it is necessary to change the position of the control damper, which is located in the pan. The set temperature is maintained in the system automatically.

Summary and diagnostic guide

Let's summarize all the cases why the cooling system does not work and their description. The table can be used as a kind of guide, which is enough for preliminary diagnosis of breakdowns.

Typical breakdowns of models with NoFrost

Full NouFrost is popular among users, in which the refrigerator does not need to be defrosted (this needs to be done very rarely for preventive purposes - once a year). With NoFrost, the refrigerator compartment is cooled by a cold flow forced by a fan, and the heating element periodically heats the evaporator in the freezer so that it thaws.

Features of two-compressor refrigerators

The compressor is the main functional element, a motor with a container of refrigerant. Two-compressor refrigerators are more reliable, since the load on each motor and vessel with freon is significantly reduced. Still, breakdowns, although much less common, are observed. The problems are similar to those described, but it must be taken into account that each chamber has its own refrigeration circuit with the indicated elements. A malfunction in one compartment does not in any way affect the operation of the second.

What you can do yourself

Trivial problems cannot be ruled out. Options that you can fix yourself:

• check the settings for erroneous high/low temperatures. Often the upper chamber in the refrigerator does not freeze precisely because of incorrect settings, especially if the product is new and just connected;
• two-compressor models have the option of separately turning off the chambers - perhaps one of them is accidentally deactivated;
• a one-time failure is possible - you need to defrost and start the unit again;
• skewed doors, incorrect position of hinges: from wear, when overhanging. It is necessary to check and bring these elements into the correct position (tighten bolts, fastenings, etc.);
• distortion and breakage may occur due to incorrect adjustment of the legs - despite its apparent insignificance, this factor is extremely important, as it affects the entire system. It causes not only a loose fit and leakage of cold, but also incorrect movement of flows, refrigerant, and rattling;
• In most cases, you can replace the seal yourself by purchasing it at a specialty store.

Typical malfunctions of individual models

Household refrigerators from each manufacturer have their own weaknesses, which are associated with the original engineering features. This is also typical for two-chamber units from Atlant. Breakdowns can occur both in older models produced under the Minsk brand and in new units:

1. Models МХМ (130, 152, 161) – significant freezing of the rear wall of the freezer box. The problem is related to the design and placement of the chamber evaporator. To eliminate it, you need to conduct a detailed diagnosis of the circulation system, eliminate the identified defect, replace the dryer filter and refill the refrigerator.
2. MХМ models (260, 2706, 2712) – capillary tube clogged. In the event of such a breakdown, the freezer compartment operates normally, but the refrigeration compartment has no or insufficient cooling. To clear the blockage, you need to blow out the capillary tube. Carrying out the procedure yourself requires skills, so it’s easier to call a specialist.
3. MXM models (1704, 1717, 1741, 6024) equipped with two compressors - in these refrigerators, a common problem is refrigerant leakage through the circuit system and in the foamed part of the box. A characteristic feature of the problem is the operation of the compressor in normal mode when the compartment temperature is violated. Troubleshooting requires connecting a mounted evaporator to the system in the refrigeration compartment.

Reference! The complexity of breakdowns is largely tied to the engineering design of the refrigerator - if there is only one compressor in a single compartment or in a divided refrigerator, then the circulation system is common and temperature regulation is carried out in a combined way. In the case of a double circulation circuit with an additional motor, each of the compartments operates autonomously (if the system does not provide for the generalization of control units to a common controller).
