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.

If the reason is in the thermostat

As a rule, the thermostat in the refrigerator is located on the front panel or in the chamber of the device, and is designed to set the required temperature. The most common malfunction of this element is the stem sticking out. You just need to put it in place. However, in some cases, the cause of the malfunction may be the failure of the thermostat (for example, due to a short circuit in its housing after water enters due to inaccurate defrosting), and then its replacement is also necessary.

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.

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.

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.

More information about faults

Failure of seal material

As a result of depressurization of the refrigerator doors, warm air constantly enters the chamber. To maintain the desired temperature, the refrigerator does not turn off, the unit continues to operate continuously. After replacing the gasket, the defect is eliminated, the required temperature is maintained for a long time.

The mechanism does not stop, the temperature is lower than planned

When the freezing function is disabled, the unit works, the refrigerator does not turn off. Why - poor performance of functions by a compressor controlled by a thermostat: the relay contacts are stuck together, unable to open the circuit, the shutdown does not work, the temperature sensor does not give a command to interrupt the relay contacts. The best solution is to replace the relay with a new one, if there is no option, hit it . In most cases, the contacts return to working condition. The thermostat power button may fail. You can check by turning the knob counterclockwise. In most cases the device turns on. Modern electronic control allows the board to be defective, which is why the command to turn off the engine cannot work.

Insufficient temperature in the chambers, no shutdown

The reason for continuous operation of refrigeration chambers may be a leak of refrigerant. You are faced with the result - deterioration of the refrigerator motor. After stopping, the unit is dismantled, the leak is found, the crack is eliminated, and the cooling system is completely recharged with freon. After defrosting, repairs must be made by a qualified worker. The work is responsible and takes a long time. The approximate cost of the service is about 3,500 rubles.

An ice bridge may form in the cooling system after burnt compressor oil enters. Violation of the circulation of the cooling agent disables the compressor motor, the unit works without stopping. After it stops and defrosts, the congestion is removed, and the refrigerator begins to function in the desired mode. For long-term operation, regular defrosting of the refrigerator is necessary. Modern refrigeration systems need to be defrosted twice a year. Old stamps defrost as ice accumulates in the chambers. It is necessary to constantly inspect the irreplaceable “home friend”, and then carry out minor preventive repairs.

The main thing is not to think about why the refrigerator is not working, but to remember that a refrigerator that cannot be switched off will lead to the burnout of the motor windings, the need to call a technician, and the search for alternative protection for spoiled products.

Troubleshooting Tips

If the refrigerator does not turn off, try to find the reason, use the tips in the article, and work with the unit. We think that after this your “home glacier” will work well.

There are many reasons why the refrigerator constantly works and does not turn off. This situation can arise not only in older models, but also in new equipment. We immediately draw your attention to the fact that it will not always be possible to solve the problem yourself, even if you are an experienced electrician. The fact is that repairing some breakdowns requires knowledge in the field of refrigeration equipment: you need to be able to refill freon, detect the exact location of the leak, and also look for the so-called “blood clot” in the system. However, you should not be upset ahead of time, since in most cases the malfunction is simple and you can independently repair a refrigerator that does not turn off around the clock. We will tell you further what to do for repairs!

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.

Refrigerator repair Biryusa

When the temperature of the controlled environment increases, the contacts close, and when the temperature decreases by the value of the dead zone, they open. Turn on the freezer and after 2-3 hours of operation the freezer will be ready to load food. The temperature is maintained in the lower refrigerating chamber. When replacing the thermostat and start-protection relay, check the integrity of the factory seal. There is no cooling when the compressor is running. Refrigerant leakage from the unit's piping system. Determine the location of the refrigerant leak by the presence of oil stains on the unit's pipes or with a leak detector.

Malfunctions are associated with failure of sensors and relays. When there is no refrigerant, the power consumption is less than W.

The number of springs in the suspension ranges from two to four. In this case, the power consumption should be within 10...12 W.

When replacing a light bulb, it is necessary to remove the diffuser 14, as shown in Fig. In many designs of thermostats it is absent.

On the outside of the casing, special removable clamps or blocks are put on the feed-through contacts for connection to the electrical wiring of the unit. Design of hermetic compressors A compressor coupled to an electric motor without an intermediate gear and located with it in a common tightly welded casing is called a hermetic compressor or motor-compressor.

Glass adheres well to metal and ensures the tightness of the casing. As the piston moves downward, the working volume of the cylinder increases the volume of the cylinder above the piston and the pressure of the refrigerant vapor in it drops. The evaporator inlet is warm. Refrigerators have a number of comfort elements: the ability to rehang the doors for right- or left-hand opening, as well as rearrange shelves and barriers in height with an interval of 50 mm; limiting the opening angle of the refrigeration chamber door; the presence of a system for automatically defrosting the evaporator of the refrigeration chamber and removing melt water outside the refrigerator with subsequent evaporation.

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.

Basic faults

So, now we’ll do the following: we’ll look at each cause of the breakdown in turn and how to repair it ourselves.

The door does not close tightly. In fact, this is a very commonplace option, but we still encounter this often. The point is not even that you did not close the door completely; perhaps the rubber seals have simply worn out and need to be replaced. How does this relate to the refrigerator not turning off? Everything is very simple - warm air enters one of the chambers, as a result of which it heats up. The temperature sensor sends a signal to the “brains” that the chamber needs to be cooled, and as a result, a closed cycle occurs: heat penetrates under the seal, and the compressor tries to lower the temperature by working without shutting down. At the same time, it seems to you that the equipment does not freeze at all or does not cool well, but it works. You can do the replacement yourself, the main thing is to find the same seal and carefully stick it on.
You have set this operating mode. As we said above, inattention and setting the temperature as low as possible can be the reason why the refrigerator runs and does not turn off all day. The cooling parameters need to be checked immediately, and then look for other possible faults.
High room temperature. When we looked at tips for choosing a refrigerator for your home, we paid attention to the fact that each appliance has its own climate class - the temperature conditions under which the device can operate. For example, if you installed equipment in a room where it is +30 o C, the compressor will naturally work without stopping. In this case, you need to move the refrigerator to a cooler room.
The thermostat has failed. If the reason is electrical, it is a malfunction of the thermostat or temperature sensor. In this case, you need to ring the product with a multimeter and if you find that when the set point is reached, the relay does not open the contacts, replace it. Replacing the thermostat or temperature sensor (depending on what is not working) with a new one will not be difficult.
The compressor has broken down. It also happens that the compressor works without interruption because it cannot “catch up” to the set temperature, so the refrigerator makes noise and does not turn off or does so rarely. At this point you will have to replace the part with a new one, unless, of course, the cause of the breakdown is trivial - placing the equipment in a warm room or damage to the seals. Replacing a compressor is not at all difficult; the main thing is to choose a model with the same characteristics.
Refrigerant has leaked from the system. It is extremely difficult to repair a leak with your own hands; in this case, you will have to call a specialist, whose work can cost up to 3,500 rubles. If you yourself know how to add freon to the system, do it and observe the equipment after refueling - whether the refrigerator turns off or works constantly and does not turn off.

Finally, I would like to note that the refrigerator malfunctions listed above can occur even in modern models with the no-frost function and other additional parameters. We recommend browsing thematic forums to view information about your specific equipment manufacturer, for example, Indesit or Ariston. Very often, people who have encountered a similar problem describe it in detail with all the smallest nuances. This way you will know exactly what needs to be done for repairs and, in fact, why the failure occurred.

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.

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.
