Malfunctions of the Biryusa refrigerator - main breakdowns and their elimination

Refrigerator Biryusa two-chamber - malfunctions

Biryusa two-chamber refrigerators with one compressor are the main products of the plant. The configuration uses reliable imported units. If the requirements for the operation of the parting are met, problems arise as a result of metal fatigue, exhaustion of seats and wear of seals.

Signs of trouble:

the compressor runs without stopping;
the motor does not turn on, or turns on for seconds;
the cells do not maintain the regime;
The compressor switches off noisily.

Each of these signs requires diagnosis; there may be several reasons. Some breakdowns of Biryusa refrigerators are minor and can be repaired on your own, while others can be repaired by a professional.

Much depends on the model. It’s easier to find and fix faults in an electromechanical refrigerator with drip defrosting yourself. It is reasonable to entrust a two-compressor refrigerator with electronic control and a No Frost system to a specialist.

Several types of breakdowns of Biryusa 125

The main problems with the Biryusa 125 refrigerator are:

failure of the compressor, which does not work at all or turns on periodically;
control module malfunction;
problems with the temperature sensor;
wear of the rubber seal, which can cause water to remain in the refrigerator and food to freeze.

CAUTION: Among the reviews about the refrigerator you can find information about the not very high quality of the doors. Some users even had to change them during the first two years of use. Due to faulty doors, Biryusa 125 may even turn off.

Malfunctions of relay P-1 of the Biryusa 3 refrigerator

The most common breakdown in a refrigerator is the failure of the R-1 starting relay. If your refrigerator turns off with a loud click, it's time to replace the relay. This node is identical in Biryusa models 3, 6, 18, 22.

The reasons for incorrect operation may be oxidized contacts of the starting winding. The thermal fuse consists of a spiral and a bimetallic plate in contact. If there is a short circuit in the motor windings, the relay opens the contacts, interrupting the start.

When starting the motor, the device protects the motor winding from increased current, preventing the windings from overheating. After starting, the current decreases and the relay opens.

If a malfunction is detected in relay P1 of the Biryusa refrigerator, it can be repaired by finding the cause:

burning or melting of contacts;
destruction of the integrity of the nichrome spiral;
coil jamming or problems with the rod.

Any breakdown takes a long time to brew, gradually, in the first stages it is easier to eliminate it. Therefore, you need to listen to how the equipment works, clean the ice in time, and remove dust from the rear grille - the condenser.

General rules for replacing the start relay in refrigerators

The start-up relay, despite its small size, is important for the operation of the unit. It performs the following functions:

starts the motor-compressor engine;
organizes stable operation of the refrigeration unit, blocking the effects of power failures;
protects against temperature changes.

The starting protection mechanism combines two types of relays: thermal and starting. They are located in one building. A similar design is used in domestic and imported household appliances.

Problems in it are expressed through extraneous noise (knocks, humming, rattling), problems with starting the motor-compressor (does not turn on at all, starts and immediately dies down, takes too long to get into operating mode) and frequent activation of the protective part of the start-protection relay. These symptoms are caused by faults both internally and externally. The reasons explaining the latter include unreliable fastening or incorrect installation of the part inside the electrical circuit.

An accurate diagnosis can be determined only by disassembling the element completely. It is quite difficult to do this without the appropriate experience and special knowledge. One awkward movement can damage the unit forever.

The check begins by removing the cover. The first thing that catches your eye is the contacts. Particular attention should be paid to the nest from which they come. If traces of burning or oxidation are noticeable, then there is no point in further disassembling the part. It should simply be removed and replaced with a new one. If there are no problems with the contacts, the technician must inspect the rod and coil with the core.

If there are no obvious problems, all removed parts are cleaned with an alcohol wipe (from dirt) and sandpaper (from corrosion). The most common reasons include:

problems with one of the relays (thermal or starting);
violations of the regulation system;
contact divergence;
problems with the motor-compressor itself.

All of the above can be solved by replacing the relay. Before carrying out diagnostics, you should prepare the necessary tools. In particular, a flathead screwdriver and a tester. This is a device that checks the functionality of the spare part. It will help find the cause if a visual inspection does not produce results. You will also need a wiring diagram for your refrigerator. Without it, it will be difficult for a non-professional to understand.

A new or repaired start-up relay is installed as follows:

Install a new mechanism in place of the old one.
Screw the screws that attach the element to the compressor frame (mount the bracket).
Fix the external contacts using the previously marked wires.
Install the block and return the wire clamp to its original position.

Refrigerator Biryusa 131K – malfunctions

The model is two-chamber with a bottom-mounted freezer. Electromechanical control, drip defrosting in the positive chamber. The total volume of the refrigerator is 345 l, 4 drawers in the freezer are retractable. Isobutane is used as a refrigerant.

The most common question asked on forums is why the temperature in the upper chamber is higher than the target, but everything is fine in the freezer. Experts consider a common cause to be a lack of refrigerant. But after diagnostics, other breakdowns of the Biryusa refrigerator may also be revealed:

thermostat malfunction;
loose seal or door misalignment;
The light inside the camera does not turn off.

The most expensive operation is refrigerant injection. In order to finally make sure that there is not enough freon in the circuit, you should defrost both chambers. If, after turning on, the freezer stops freezing, you need to check for leaks in the circuit and pump in refrigerant. If the problem arose as a result of mechanical damage, the freezer will need to be replaced.

A removable nuisance is condensation leaking into the freezer, causing lumps to freeze. The reason is a clogged condensate drain from the refrigerator. It needs to be defrosted and cleaned of any crumbs and packaging. Water in the refrigerator compartment indicates a clogged hole, and when the water has nowhere to go, it gradually enters the freezer through leaks.

If there is no lighting in the chamber, the light bulb is working properly, or the refrigerator occasionally generates current, an inspection of the electrical wiring will be required - the insulation of the wires has been broken somewhere.

How to remove a starter relay

The part is removed when checking its functionality, as well as in case of damage. The procedure includes the following steps:

Disconnect the device from the power source;
Wait a while to de-energize the entire system;
Remove the screws from the bottom cover of the refrigerator where the compressor is located;
Disconnect the contacts connecting the relay to the engine;
Remove the screws or latches holding the part in place;
Carefully remove the relay.

Note: Buy a new mechanism taking into account its brand. If it is not on sale, select it according to the type of compressor.

Refrigerator Biryusa 130 RS - malfunctions

A two-compressor refrigerator with electronic control and automatic defrosting of the cold chamber is one of the modern models that is not inferior to foreign brands in technical parameters. A light indication indicates an increase in temperature in the cells, and an audible signal indicates an open door.

Malfunctions are associated with failure of sensors and relays. It is important that any Biryusa refrigerator is connected through a voltage stabilizer, but for electronic control, unstable power supply is the main cause of failure. Among the malfunctions, the control unit most often fails. The failure of the unit is clearly determined if there is no response to commands. After pressing the “Stop” button for 5 seconds, the display should go out. If this does not happen, other commands are not executed - the master can determine the malfunction.

Freon leakage problems can arise due to poor connection of the tubes to the evaporator. It is necessary to observe whether the doors are warped. The structure is heavy, and the brackets for it are rather weak. But the device has a 3-year warranty, all comments are corrected by the service department free of charge.

Where to look for a refrigerator thermostat

Well, we have examined the structure and characteristics of the device, let’s move on to the next question. To repair the thermostat yourself, you first need to find it.

This is not difficult to do. The thermostat is always connected to a knob or button for setting the temperature in the chamber. Depending on the refrigerator model, the thermostat can be installed:

inside the refrigerator compartment;
outside the refrigerator.

Inside

This arrangement is typical for earlier models of Atlant and other refrigerators. If you open the refrigerator compartment, you will see a small plastic box placed on one of the panels. This is the thermostat. To get to it, you just need to remove the temperature switch knob and unscrew the protective housing.

Outside

Modern refrigeration units are designed a little differently.
In them, the device we need is located outside the refrigerator chamber. It is usually located at the top of the refrigerator, above the door. But it may be in another place. In any case, the principle is the same - the temperature regulator is located in the same place as the switch knob. To get to it, you need to remove all protective parts. See also -

Refrigerator Biryusa 18C - malfunctions

Single-compressor models with mechanical control, bottom freezer and automatic defrost are easy to operate. The surface is made of decorative plastic framed with an aluminum corner.

A heater for defrosting ice is attached to the rear cavity of the evaporator. It turns on between compressor cycles. Both chambers are cooled by sheet-tube evaporators.

The main causes of malfunctions are considered to be;

temperature sensor failure;
faulty start relay;
freon leak;
clogged drain hole and tube.

If the refrigerator or subzero chamber is not working, there may be several reasons. An accurate diagnosis can be made by a specialist based on a combination of symptoms. Perhaps the ice is freezing due to a failure of the defrost thermostat; the drainage tube is not only clogged, but cracked. The absence of freon in the system or a plug in the capillary will help determine the temperature of the condenser.

Problems with the Biryusa 6 model

In terms of size, the Biryusa 6 model corresponds to budget refrigeration units; in other characteristics it is quite capable of being compared with more expensive solutions. But, even with high wear resistance and reliability, the model may experience the following breakdowns:

clogging of drainage capillaries, which causes an unpleasant odor;
breakdown of the compressor or temperature sensor, causing a loud humming sound - the problem requires immediate repair of the faulty device;
malfunction of the automation or compressor, as a result of which the required temperature is not maintained in the freezer and refrigerator compartments.

The list of Biryusa 6 faults includes problems with the electrical circuit, which can break or burn out. Because of this, the sensors stop functioning and the operation of the equipment is disrupted. Owners of the same equipment are faced with breakdowns of the starting relay, which requires replacement rather than repair. The electrical diagram of the refrigerator will help determine the location of the part, after which it is enough to disconnect it from the terminals and install a new one.

Malfunctions of the Biryusa 226C refrigerator

The two-chamber model with a bottom freezer has one compressor and an electromechanical thermostat. Energy efficiency class of the refrigerator Biryusa 226C - C.

Often, loss of cooling is due to a faulty thermostat. The breakdown is accompanied by signs:

The refrigerator motor does not turn on, the cooling does not work, and the light in the compartment is on;
the compressor runs without interruption;
the refrigerator is very cold, food freezes in the plus chamber;
The refrigerator does not freeze, while the thermostat knob is in the working position.

The purpose of the thermostat is to read sensor readings in the chambers and regulate the operation of the compressor. In case of failure, a comprehensive repair of the unit is required.

Other reasons may be a malfunction of the cooling circuit associated with a freon leak. A failure of the start relay or a malfunction of the compressor is determined by a specialist.

Start protection relay device

Let's look at the relay design using the Tablet as an example. The part we are interested in is located near the compressor motor. Its color is black, as it absorbs heat better than all other shades. Next, you need to note two phases (one for 220 V, and the other for grounding) and, accordingly, two inputs/outputs. Some refrigerator models have three phases (the third is considered the ground phase). There is also a motor winding and a direct starting winding.

Connecting the refrigerator start relay is not difficult. The main thing is to have certain skills, an electrical diagram and instructions for the refrigerator. To make work easier for craftsmen and ordinary users, the wires are already painted. You just need to remember their location when removing the old relay, and when installing a new one, return them to their place. Next, all that remains is to connect a working device.

But even wires, each decorated in its own color, will not prevent a malfunction. Regardless of the operation, all movements must be careful and smooth. With one sharp jerk it is possible to completely damage the refrigerator. Before you start working, you should check all contacts. The easiest way to do this is to remove some paint from the body, but this should only be done as a last resort.

Malfunctions of the Biryusa-18 refrigerator

The refrigerator is two-chamber, assembled in a metal case, painted white. Energy efficiency - class C device. One compressor with a common cooling circuit. The refrigeration chamber is equipped with a T-130 thermostat, a VOK-2 switch and a 15 V incandescent lamp. An evaporator defrost is installed in the chamber and is turned on by the T-130 signal.

The cause of ice freezing in the refrigerator compartment may be a malfunction of these components or the influx of fresh air through leaks in the door. Diagnostics of models 18 and 18 C are the same. They are distinguished only by their appearance. The refrigerator compartment does not work - watch how to diagnose and repair in the video.

How can I troubleshoot?

In most cases, refrigeration repairs require the intervention of a qualified technician. The exception is when the owner himself has the skills and can read the diagrams. Let's look at some of the most common causes of failure and how to fix them.

There is a large amount of ice frozen on the evaporator, as shown in the photo below. There may be three reasons for this:

Failure to completely defrost ice during a previous defrost or failure to defrost over an extended period of time. To fix this, unplug the device, defrost, wipe and dry. It is also recommended to leave the refrigerator open for 1-2 hours for ventilation. The refrigerator can be connected to the network;
The operating cycle is interrupted; the problem may be that the capillary tube of the thermostat is simply squeezed out of its socket. To correct the situation, this tube should be returned to its place;
The motor-compressor turns off at the wrong time. In this case, the thermostat has failed. To solve the problem, it is necessary to replace the thermostat.

Malfunctions of the Biryusa-22 refrigerator

The Biryusa 22 refrigerator is two-door, the freezer is on top. There are two operating positions on the installation panel - “Storage” and “Freezing”. The control unit has a voltage indicator and a middle bar heating switch. The temperature in the chambers is set using a common regulator with graduation in 7 positions.

You can independently eliminate only some problems associated with improper installation of the device or contact of tubes with the housing or other components. You can separate them a little or put soft spacers. Tighten the bolts. Check whether the installation of the refrigerator complies with the requirements of the operating instructions. If a smell occurs, you need to wash and ventilate the chamber and replace the burnt out light bulb. Experts are called when irreparable problems arise.

Typical malfunctions of the Biryusa 22 refrigerator:

The electrical wiring is broken, current passes through the housing, and the light in the chamber does not turn on. Here the voltage in the network, contacts with terminals in the relay, and winding resistance are checked.
The thermostat is faulty. The reasons are a breakdown in the electrical circuit or a malfunction of the bellows tube, but the thermostat needs to be changed in any case.
Faulty compressor or start relay.
Refrigerant leak or capillary tube clogged.
If a fur coat grows on the evaporator, the heater is not working, the reason is the thermostat or a malfunction of the device itself.
The heater on the partition does not work, the condensate does not evaporate.

The Biryusa 22 refrigerator has been operating for decades without breakdowns if the manufacturer’s requirements are met. You need to remember that the device will not cool well if the room temperature is below +16 and above 35 degrees, and there is high humidity in the room. This is not considered a breakdown, the climate class of the device is N.

Current type protection relay

An asynchronous motor is a complex electrical device that is prone to breakdowns. If a short circuit occurs, the circuit breaker installed in the distribution panel will trip.

If the fan, which cools the winding and mechanical moving elements, fails, the built-in thermal protection of the compressor will react.

However, a situation may arise when the motor begins to consume 2-5 times more rated current for a long time (more than 1 second). Most often this occurs when there is an unplanned load on the shaft resulting from a jammed motor.

The current increases, but does not reach the short circuit values, so the machine selected for the load will not work. There is also no reason for the thermal protection to turn off, since the temperature will not change in such a short period of time.

The only way to quickly respond to the situation and avoid melting of the working winding is to trigger the current protection, which can be installed in different places:

inside the compressor;
in a separate current protection relay;
inside the start relay.

A device that combines the functions of turning on the starting winding and current protection of the motor is called a starting protection relay. Most refrigerator compressors are equipped with just such a mechanism.

The action of current protection is based on three principles:

as the current increases, the resistance increases, which leads to heating of the conductive material;
under the influence of temperature, the metal expands;
The thermal coefficient of expansion differs for different metals.

Therefore, a bimetallic plate is used, which is welded from metal sheets with different expansion coefficients. Such a plate bends when heated. One end of it is fixed, and the other, deviating, opens the contact.

The plate is designed for a temperature response when a current of a certain strength passes. Therefore, when replacing the start-up relay, it is necessary to check its compatibility with the installed compressor model.

What could be the causes of the problem?

Due to the typical nature of all refrigerator breakdowns, we can conclude that they must have characteristic features. This is true. Therefore, you can often quickly diagnose it yourself. To do this, you only need to know about the key features of the malfunction, so you can decide what is best to do in a particular situation - repair the refrigerator yourself or involve a specialist in the work.

Even the main types of breakdowns of the refrigerator are quite numerous, but they are all typical, that is, they have characteristic features, which simplifies the task of detecting and eliminating them

All breakdowns can be divided into several large groups:

mild (not a serious problem and can be fixed by the user);
complex (repairs will be carried out by a qualified specialist, for which you will have to pay);
hopeless (rare, can be solved mainly by purchasing a new refrigerator).

Main signs of refrigerator malfunctions

Note! To save money and time, you need to be able to identify breakdowns from all of the listed groups - this will allow you to take appropriate measures in time or even avoid the problem.

How to protect your freezer from damage?

There are several tips for saving your freezer:

Do not freeze food that is above room temperature. Wait until they cool down.
Do not help the device defrost.
Close the door tightly to prevent warm air from entering.
Set the temperature on the thermostat correctly. Monitor it constantly.
Watch for water accumulation inside. Get rid of it to avoid rust.
Follow the operating instructions.

There are many reasons why your freezer won't freeze. If you are well versed in details and know where and what is located, you can make the replacement yourself. It will be more economical than calling a specialist.

Why does the refrigerator constantly work?

The basis is:

failure to close the lid due to poor placement of objects in the chamber, which allows warm air to enter there. The temperature sensor tries to maintain the required temperature, the motor runs constantly. You just need to rearrange the contents and close the door tightly. When the desired temperature is reached, the compressor will automatically turn off;
the place for its installation is inappropriate - the battery is mounted close to the heat pipe. Move the unit away from the heating source;
serious breakdown, it is necessary to de-energize the refrigeration unit without expecting it to overheat or the windings to catch fire.

The refrigerator works and does not turn off

If the refrigerator (or rather, its compressor or motor) does not turn off for a long time or does not turn off at all, constantly working, the reasons may be the following:

The unit was installed incorrectly. For example, the owner forgot about the need for an air gap between the case and the wall, or placed the device near the battery.
The room temperature is too high and does not correspond to the climate class of the refrigeration equipment.
The thermostat was set to the lowest possible temperature given the hot environment.

A similar option is to activate the super-freezing function (available in almost all modern No Frost refrigerators), due to which the device does not turn off after the allotted time (on average 10-15 minutes).

All of the above problems can be eliminated on your own and quickly enough, but often the causes can be more serious.

Group No. 2. Complex breakdowns

If all the recommendations listed above did not help to identify the cause of the refrigerator’s malfunction, then you cannot do without the help of a specialist, because eliminating such complex problems requires special skills and tools.

Refrigerator compressor

Signs of such malfunctions include:

long pauses in the operation of the electric motor (combined with insufficiently low temperature);
broken heater (applies only to No Frost models);
incorrect operation of the temperature sensor;
improper operation of the compressor;
motor overheating;
freon leak;
that the refrigerator does not work at all.

A frozen fan is a common cause of abnormal refrigerator operation. All that is needed to eliminate the problem is to defrost the unit. Even if it turns out that the fan is burnt out, most men can handle the replacement

On a note! We will not describe such problems in detail, since specialists should still deal with them. So let's move on to the next point.

Refrigerator electricity consumption calculator

Go to calculations

The warning light, together with the indicator of the selected mode, can indicate that the operating program has been selected incorrectly by the user. Therefore, you should check whether the button that activates defrosting or quick freezing is turned off

Group No. 3. Hopeless faults

In almost all cases, any household appliance can be repaired. Fortunately, spare parts are sold for all models, and in fairly large quantities. However, in some cases it is better not to spend money on expensive repairs, but to purchase a new refrigerator.

Freon leaks are caused by breakdowns like the one shown in the photo. Most often this is a consequence of improper operation of the refrigerator by the owner.

For example, if the unit is already 8-10 years old, and repair work will cost a considerable amount. This period, by the way, is the average operating period of any refrigerator. Therefore, there is no point in paying ¼ of the cost of the unit to replace the electric motor and still wait several weeks until the required structural element is delivered. After all, a new incident may occur soon.
