Atlant refrigerator does not work: diagnostics and repair without a technician

4.8 / 5 ( 17 votes)

Atlant refrigerators are popular not only in the native Belarusian market, but also abroad. They work well, are easy to use and are affordable. But, like any other complex equipment, a refrigerator can break down over time.

In our article we will look at the reasons why the Atlant refrigerator most often does not work. We'll tell you how to diagnose the problem yourself.

But for repairs it is better to contact a trusted service. This is a guarantee of safety and reliable operation of the equipment after the fault has been fixed by the technician.

Pipeline blockage: how to fix it?

Thanks to the capillary pipeline, the freon (refrigerant) maintains different pressures. When it enters the pipeline the pressure is equal to the condensate pressure. As it moves, it drops to boiling pressure. And at the exit the agent boils in the evaporator.

But the agent does not travel through the pipe alone, but together with the compressor oil. This is why paraffins appear on the walls of the pipeline. When there are a lot of them, a blockage forms.

Signs of a malfunction in the Atlant refrigerator:

• The motor is running, but the temperature in two chambers is higher than normal.
• The indication is on.
• Or there is an error H on the display.

What to do:

• To eliminate such a malfunction in the Atlant refrigerator chamber, you need to replace the capillary pipeline. The technician will also change the filter along with it. Then it will create a vacuum and fill it with new freon.
• When the blockage is partial, you can try to remove it with a jack.

Connecting a compressor without a switch

Connecting a compressor to a system without a relay is carried out according to the diagram that we have given below.

Motor connection diagram without relay

You need to take a conductor with two wires on one side and a plug on the other side. One contact should be connected to the main point, and the other to the working winding. Now these contacts should be connected and the plug plugged into the socket. In this case, a working refrigerator will function.

Compressor failure on Atlant refrigerator

How to repair the compressor in the Atlant refrigerator?
The function of the compressor is to ensure that freon passes through the pipeline properly. The Atlant refrigerator compressor may not work because:

• The winding has broken.
• The winding has shorted out.
• It gets stuck when the motor hums and there is no pressure.

Signs by which you can understand that the Atlant refrigerator compressor has failed:

• It turns on, but then immediately turns off.
• Works with sound, but the agent does not move through the pipe.
• It does not turn on, but there is light in the refrigerator.
• The indicator on the refrigerator is on.
• Or there is an error on the panel.

What to do:

• Replace the motor, filter and refill the refrigerator with freon.

Schemes and principles of operation of a two-chamber single-compressor

A refrigerator compressor consists of an electric motor with a vertically mounted rotor and a piston that compresses the refrigerant. These components are housed in a metal housing made of two halves. They are welded together; replacement of elements is not provided. In case of breakdown, the entire compressor is replaced completely.

The motor is controlled using a relay. It is connected to temperature sensors that analyze the conditions in the cooking chamber and in the freezer.

In modern models, the electrical circuit contains an additional ground loop.

A household single-compressor refrigerator uses isobutane or freon as a refrigerant. The gas is under pressure in the cooling circuit. On the back of the device there is a tube for refilling it if necessary.

The refrigerant in liquid state is pumped by the compressor into the condenser. There it is compressed, and the condenser radiator removes the excess heat that is released. During the compression process, moisture is also released, which is removed by a filter at the bottom of the heat exchanger. Through the capillary channel, the substance enters the evaporator of the freezer. There the refrigerant transitions from liquid to gaseous state. The gas enters the compressor through the tubes.

The fundamental difference between a single-chamber refrigerator with one compressor and a two-chamber Atlant is that the latter has a partition between the working chambers. Each of them has its own evaporator, they are cooled separately.

Atlant refrigerator thermostat malfunction

How to fix the thermostat in the Atlant refrigerator?

If the freezer in the Atlant refrigerator does not work, most likely the problem is the thermostat. It is he who is responsible for cooling.

Signs of a thermostat malfunction in a two-chamber Atlant refrigerator:

• Camera does not work.
• The Atlant refrigerator does not turn off.
• It starts sometimes, but the degree is high, which can be understood by the active light bulb.

What to do:

• Install a new thermostat.

Types of refrigerators

Based on the distribution of the freezer chamber and the medium temperature maintenance chamber, they can be divided into single-chamber, two-chamber, three-chamber, etc. There is also a two-level closet and a so-called French door.

Single chamber

Double chamber

Three-chamber

System malfunction full no frost

Malfunctions of the No Frost system in the Atlant refrigerator

The full no frost system consists of a sensor, a heating element, a timer and a fuse. The evaporator is located in the freezer, and the upper chamber is cooled by the fan.

If the equipment works correctly, then at a low temperature the sensor is triggered and turns on the heating element so that the ice begins to melt. Therefore, with the no frost function, manual defrosting is not necessary. If the system breaks down, the evaporator becomes covered with an ice crust and the cold does not enter the chamber.

Signs:

• There is a lot of ice in the freezer.
• The refrigerator compartment of the Atlant refrigerator does not work.
• There is an error H on the display.

If you defrost the refrigerator, it will work for a couple of weeks, but then the same problems will appear again.

What to do:

• Contact the service to have a technician repair the No Frost system.

Device

The Atlant household refrigerator has a body with double walls, between which there is heat-insulating material. The doors can be hung on both the left and right sides. The following are responsible for the correct operation of the device:

• single electric motor unit with a piston compressor;
• radiators inside working chambers;
• condensation block on the rear wall;
• thermostat with temperature sensors;
• relay;
• electronic control unit.

The compressor is connected to the radiators by copper and steel pipes. The refrigerant pressure is regulated by additional elements.

Some modern models have a heat exchanger with the No Frost operating principle, a compartment for cooling water and an LCD display.

Freon leak in Atlant refrigerator

Freon leak in the Atlant refrigerator
If your Atlant refrigerator is more than five years old, most likely you will encounter a problem such as a freon leak:

• Drip evaporator . A part made of aluminum eventually deteriorates, cracks, and the agent leaves.
• Freezer heating circuit . It is made of steel. During operation, the metal rusts, especially if there is high humidity, and leakage occurs.
• Connections . Depressurization occurs, and the agent escapes through small cracks.

Refrigerator Stinol

Stinol refrigerators combine all the best achievements in the field of refrigeration technology - high reliability, long service life. The difference between the refrigerator models is insignificant: a different connection diagram and different dimensions.

Leak in drip evaporator

Leak in the drip evaporator of the refrigerator
The drip system works like this: when the motor is operating, frost appears, which melts when the compressor is turned off and there is a plus in the chamber. Melting frost flows through the drain into a container on the motor.

At the same time, the evaporator is often made of aluminum, which means it deteriorates over time. And the agent leaves through small cracks.

Signs:

• If there are two compressors, then the refrigerator may not freeze, but Atlant’s freezer will work well. Although the compressor is working. Maybe ice. And if you don’t turn it off, then after a while the motor will also fail.
• If there is only one compressor, then the Atlant refrigerator stops working. The compressor is running smoothly or is faulty. The condenser does not heat up, there may be ice.

What to do:

• Replace the evaporator.
• Check for leaks.
• Apply a vacuum to release air and remove moisture.
• Refill with agent.

How does improper operation affect performance?

As you know, caring for equipment helps to extend its service life, and vice versa. The most common mistake is cooling hot food using the refrigerator.

The main points why you should not put hot food in the refrigerator:

1. The glass shelf in the refrigerator is experiencing deformation.
2. Hot water evaporates.
3. Operation malfunction.

Glass does not conduct heat well, so it is dangerous to put food from the stove into the refrigerator, since the glass under the dishes heats up and expands, the rest does not. There may be problems with the glass, microcracks, which reduce the strength. Therefore, it is worth placing a board under hot dishes.

Hot water evaporates and settles on the walls in the form of frost. This prevents freon from taking up heat, resulting in a decrease in cooling efficiency and an increase in the load on the compressor. As a result, the service life of the refrigerator is reduced. To avoid this, you should cover your food with a lid or cling film.

The compressor operates cyclically: on, off, on, off. When hot, the compressor continues to work for a long time. Although modern technology has thermal protection for the compressor, it is still worth letting the food cool at room temperature.

Most refrigerators do not differ in connection type. But it’s still worth delving into how the circuit is connected, what it looks like and how it works. Therefore, when choosing, you should pay attention to the subtleties in the form of a connection diagram. If you understand the circuit, you don’t have to contact a service center, but can easily fix everything yourself. Saving money and time is obvious.

Leak in freezer heating circuit

Leak in the freezer heating circuit
The tube along the freezer circuit in the Atlant two-chamber refrigerator is needed to allow condensation to escape, otherwise the system will not work. Thanks to the tube, the chamber heats up and condensation does not accumulate. The pipe is made of metal, so over time it will wear out, causing loss of agent.

Signs of a leak:

• Rust.
• High temperature in the freezer and/or refrigerator.
• The engine runs smoothly or does not start.
• Ice.

What to do if the Atlant refrigerator does not turn on due to a leak in the circuit:

• Trim the outline.
• Solder the pipe.
• Change the filter.
• Create a vacuum.
• Refill with freon.

When you can't do without a master

One of the first signals that your refrigerator gives in the event of a malfunction is a lit red light. It is this that shows that a serious malfunction has occurred in the operation of the refrigerator, which requires the attention of an experienced technician. Below are the main problems that may arise when the red indicator lights up:

• shortened operating cycle of the refrigeration unit;
• malfunctions of the motor-compressor;
• rapid accumulation of snow “coat” on the back side of the device;
• The refrigerator body is electrocuted.

Of course, if you have some knowledge in the field of electrical engineering, you can try to eliminate these defects yourself. Let's consider each case separately.

Shortened refrigeration cycle

A situation is possible when, due to a malfunction of the thermal relay or increased voltage in the motor circuit, the refrigerator begins to stop working immediately after being turned on. To find out the cause of the malfunction and carry out repairs, you should perform a number of actions.

1. Measure the voltage in the electrical network.
2. If the voltage does not exceed the norm, it is necessary to remove the thermal relay and connect the electric motor directly.
3. If the refrigerator is functioning properly, you should replace the broken relay with a working one.

Thermal relay

Malfunctions of the motor-compressor

If your refrigeration unit is running non-stop, pay attention to the room temperature and the position of the thermostat knob. If the latter is in standard condition and the temperature in the room does not exceed normal, it is necessary to carry out initial diagnostics of the unit

1. If the thermostat knob is in the normal position, but the refrigerator operates continuously, it is possible that the cause of the breakdown is a failure of the thermostat.
2. If a freon leak occurs, the characteristic frost will not be present on the evaporator tubes. In this case, it is better to contact a repair shop, where they will determine the exact location of the refrigerant leak and make repairs.

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

There are many reasons for this malfunction:

• insufficient fit of the door to the refrigerator body;
• increased room temperature;
• a situation where hot food is stored in the refrigerator;
• The refrigerator operates in low productivity mode.

The first thing to do in the event of a malfunction is to check whether the seal fits tightly to the body of the door and refrigerator. If this is not the problem, your device may not be operating at full capacity in a fairly warm room. Change the power to a higher level and the problem should resolve.

Snow "coat"

The refrigerator body is electrocuted

If, upon contact with the body of the refrigerator, you feel even a slight discharge of electric current, it means that the bare wires in your device are in contact with the body. A qualified technician will identify and isolate the problem by measuring the insulation resistance of the wires.

Compressor relay fault

How to repair the compressor relay of the Atlant refrigerator?
The relay has two important functions: it helps start the capacitor and protects the refrigerator when the voltage increases. The jump may be due to a short circuit. And then the relay breaks the circuit and turns off the motor.

Signs:

• The Atlant two-chamber refrigerator does not turn on or turns on and off.
• The light comes on.

What to do if the cause of the malfunction of the Atlant refrigerator is in the relay:

• Buy a new part.

Let's sum it up

Even if connecting a compressor seems like a difficult task, after studying the diagram you will be able to cope with the process. Here it is necessary to follow a sequence of actions, work slowly and thoughtfully. Good luck!

A compressor is a pumping unit with an electric drive and a motor, which circulates the refrigerant. Knowing the connection diagram for a refrigerator compressor will help you determine at home whether the engine is working or has become unusable. Sometimes you can find the cause of the breakdown on your own, but it is better to entrust accurate diagnosis and repair to a specialist.

Damage to the seal in the Atlant refrigerator

How to fix the seal of an Atlant refrigerator?

When the seal is damaged, the door cannot be closed normally and warm air from the room passes into the chamber, which can cause the Atlant refrigerator to break.

Signs:

• The door does not close tightly.
• The Atlant refrigerator motor constantly works and does not turn off.
• The light is active.
• Or error H.
• The refrigerator beeps.

What to do:

• Install a new seal.

The refrigerator does not freeze or freezes poorly

The reason that the refrigerator does not work properly may be that the door of one of the chambers is not closed well enough. This situation can arise as a result of not very tight contact of the rubber with the body. The reasons for the deformation of the seal can be different, but basically it allows air to pass through due to its wear and tear. In this case, it should be replaced.

Some users do not consider it necessary to defrost the device as indicated in the operating instructions. If you try to break off pieces of ice from the walls during defrosting, then such actions will lead to the fact that the upper chamber of the refrigerator does not work. Freon may leak due to damage to the inner lining of the housing.

A skewed door also contributes to the penetration of air into the chambers, which causes the device to stop working normally. The situation can be corrected by adjusting it. Directly below the door panel there are diagonal rods.

Lack of normal temperature inside the refrigeration unit can lead to spoilage of the food stored in it. Therefore, after repairing the device, it is recommended to wash it thoroughly using special products that eliminate unpleasant odors. After this, let it dry thoroughly, first opening the doors.

Fast Freeze Mode

For example, the Atlant refrigerator and many other two-chamber models have this function. To ensure fast freezing of food, in this mode the refrigerator compressor runs continuously until the function off button is pressed. In models with electronic control, shutdown is automatic. It is not recommended to use this mode for more than 3 days.

The article will talk about electrical connection diagrams for refrigerators from different manufacturers, answers to questions that interest you: what the connection diagram looks like, what it is, the principle of operation .

Operating instructions for a two-chamber refrigerator "Minsk"

According to the instructions, all Atlanta brand units must be operated under certain conditions.

1. Humidity no more than 70%.
2. External temperature from +10 to +32 degrees.
3. The size of the room is at least five square meters.
4. Height to ceiling – 2.5 meters.

It is necessary to pay attention to the points in the manual about the inadmissibility of the following actions:

• Defrost the device using sharp objects and prevent damage or violation of the system’s tightness;
• Place the unit close to the wall;
• Install the device near fire hazardous sources;
• Use a damaged power cord;
• Leave the operating unit unattended for more than 14 days;
• Wash the refrigerator that is turned on.

Briefly: the operating principle of a refrigerator for dummies in simple words

The refrigerator does not produce cold. It operates in heat pump mode. The principle of operation of the refrigerator is as follows: it pumps heat from the chamber to the environment.

In order to perform this task, the refrigerator contains:

• Compressor (one or two);
• Evaporator;
• Condenser (external radiator);
• Refrigerant, also known as freon.

To understand how a refrigerator works, let's remember the physics course. When any liquid evaporates, it cools. And when compressed and condensed, it heats up. For clarity, we will explain to you how the refrigerator works using examples:

1. Gaseous freon with a temperature of +5 ° C enters the compressor;
2. The compressor compresses it so that it condenses into a liquid;
3. During condensation, freon heats up to +40 degrees;
4. After this, it enters the condenser under pressure, where it is cooled to +25 ° C;
5. Freon enters the evaporator, where it expands and boils, since it is no longer under pressure;
6. The freon temperature drops to 0 degrees, it cools the refrigerator chamber.
7. In the process of taking heat from the chamber, freon heats up to +5 °C;
8. The cycle repeats again.

All this is possible due to the physical properties of the refrigerant. The boiling point of freon is much lower than 0 degrees. so it boils and evaporates in the evaporator. We have given all the numbers as an example, so that you can understand more clearly how the refrigerator works. In reality the cycle is somewhat more complicated.

How to connect without capacitor and relay

Modern refrigerators do not use a capacitor. In older models, it is needed to change the form of the refrigerant from gas to liquid. Without a capacitor, long-term operation of refrigeration equipment is prohibited, so the engine can be started without this part, but only for diagnostic purposes. Before connecting the refrigerator compressor, you will need to dismantle, that is, desolder, the capacitor. In this case, the electric motor is started through a standard relay.

If the capacitor malfunctions, the compressor can be started without it, and the motor will start working.

If this does not happen, the problem may be in the relay, or the motor is faulty. This assumption can be verified by applying current to the motor winding directly. To do this, you will need to connect a copper wire with a power plug at the end to both windings using connecting terminals.

Increasing the downtime period

It is clear that the more often the refrigerator starts, the more electricity is consumed. To reduce consumption, it is recommended to load the refrigerator and freezer compartments to the maximum. In this case, the products will act as cold generators. If the chambers are empty, the air will heat up faster, which means the device will start up more often.

To increase the refrigerator's operating cycle, especially in summer, it is recommended to open the door as little as possible.

Hot air entering the chambers much faster heats the food, causing the temperature to rise and requiring the freezing mode to be turned on more often.

Refrigerator operating principle: refrigeration cycle diagram

If the norms of operating cycles have changed while observing the operating rules, then it makes sense to check the functionality of the thermostat. Often, failure of this element leads to abnormal operation of the device as a whole. A short circuit in the motor winding is also possible.

Thus

The normal duty cycle coefficient of any refrigeration device is 0.37-0.5. This means that the unit works for 15-30 minutes, and rests for the next 25-30 minutes. If the indicator increases to 0.6 or decreases to 0.2, the device requires repair. In the first case, the integrity of the cameras may be compromised, in the second, adjustment of the working sensors is required. In any case, the adjustment of the functionality of the refrigeration device should be carried out by a specialist.

The Dnepr2 refrigerator works for 4 minutes and rests for 4 minutes - this is the cycle with an empty freezer compartment, at any thermostat position. The temperature in the evaporator and in the cabinet is normal. What causes this cycle of on and off?

I use an Atlant refrigerator. The problems started from the very purchase - it would not start. After a day or two, the switching was adjusted and the store safely transferred us to the warranty workshop, which I was able to use only a year later. It worked at 4. The temperature in the refrigerator is closer to 10 (9.7). The working time coefficient was 0.3. Worked for 7 minutes. rested 15. At the moment, the master suggested switching to the maximum mode - 7. The refrigerator worked without a break for 3 hours, after which it was switched to 6 and it turned off and began working in mode 30 and rest 30. Is this correct? What am I supposed to do? Then, when purchasing online, the seller announced a promotion of 1000 rubles on the user’s phone. I went through the registration procedure and was assigned a registration number. I called repeatedly, but never received anything. Where to contact? In general, I had a better opinion about the refrigerator until I bought it

Hello! I have an Atlant refrigerator. After replacing the TAM-112 thermostat, with an empty freezer, it works for 2-3 minutes, with a break of 6-7 minutes. Please tell me what is the reason? Thank you in advance for your response!

Atlant electronic unit without a clock, but with a sound signal

The panel is used in the series from XM-6319 to XM-6326. The screen is hidden behind the door, so the developers abandoned the time display, but added a sound signal (triggered when the HK door is open for more than 60 seconds) with the ability to turn it off.

To adjust the temperature, just click the arrows next to the desired half and set the value. The rest of the functions work according to the old scheme.
