Do-it-yourself turquoise refrigerator repair

In detail: do-it-yourself turquoise refrigerator repair from a real master for the site my.housecope.com.

One of the most important elements in a refrigerator is a thermostat or temperature regulator inside the chamber. This is a small part that signals the motor to turn on and off the cooling mode. Thanks to the thermostat, a certain temperature is maintained in the refrigerating devices. In devices of the Biryusa brand, the thermostat is a resistor located inside the refrigerator compartment. Moreover, in the dimensional models of these parts there can be from 1 to 5 units.

Thermostats in Biryusa refrigerators are located in different places of the device, depending on the model. Experts say that this element can be located:

Not far from the evaporator of the refrigerator or freezer.
Inside the chamber.
In separate parts of the refrigeration device, where additional temperature sensors are located. For example, the freshness zone for vegetables in the Biryusa refrigerator can be equipped with an individual thermostat.

At first glance, replacing the thermostat in the Biryusa 22 refrigerator may seem simple. However, it is better to entrust this work to professionals. Immediately you need to understand that the thermostat cannot be repaired. It only needs to be replaced with a new one.

Temperature regulator inside the refrigerator compartment

To replace the thermostat in the Biryusa refrigerator, the master needs to disassemble the outer shell of the device in order to get to the desired part. Usually, the body and the top cover are dismantled, under which the desired element is hidden.

The next step is to remove the thermostat. First, you need to disconnect the contacts that connect the part to the rest of the device. Then, in the Biryusa 3 refrigerator, the lighting unit is dismantled, and the thermocouple is removed. In electronic refrigeration units, the control unit is turned off and only after that the broken thermostat is removed.

In such models as Biryusa 6, Biryusa 3, operating on the basis of mechanical control, the contact parts of the part are immediately connected to connect the thermostat. After that, a thermocouple is lowered into the hole, and a sealant is poured from above. In models with electronic control, thermostats for Biryusa 22 refrigerators are connected as follows:

A wire is threaded through the back panel, which has a temperature sensor.
The wire is connected to the control module by twisting or soldering.
To protect the wires, the junction is protected by heat shrinkage.

Replacing the thermostat in the Biryusa refrigerator does not end there. It is imperative to assemble the case. Often, a new thermostat cannot be replaced with your own hands, due to the large length of the thermocouple. To solve this problem, experienced craftsmen advise placing a thermocouple under the top of the structure. Before the final assembly of the refrigeration unit to its original position, it is imperative to check the resistance of the thermostat. This indicator should correspond to the factory values.

After completing all the steps, the master with his own hands is obliged to check the Biryusa 22 refrigerator for operability.

Users of Biryusa refrigerators are generally satisfied with the quality of these devices. But, any technique fails. How to understand that the thermostat has broken down and needs to be replaced? It is necessary to pay attention to the functioning of the freezer and refrigerator compartment. If one temperature regulator is provided in the Biryusa 18 s model, both chambers will fail simultaneously.Otherwise, the compartment in which the temperature regulator failed will not work.

The second, clear sign that the thermostat in the Biryusa 3 refrigerator has broken down is the constant operation of the compressor. In this case, the food inside the chambers will be frozen. The opposite option is also possible, in which the food inside the refrigerator heats up, since the breakdown of the thermostat leads to an increase in the temperature regime.

You can learn more about the process of replacing the thermostat in the Biryusa refrigerator from the video.

Household appliances repairmen recommend not replacing thermostats in Biryusa 22 refrigerators with their own hands. At first glance, this process seems straightforward. However, if connected incorrectly, the new temperature controller may break down. To protect the equipment from secondary damage and yourself from buying a new thermostat, it is recommended to immediately contact the master.

Tell me why the Biryusa 118 refrigerator does not turn off?

This is due to the fact that intensive operation of the compressor for a long time can lead to overheating and complete failure. Since this is the most expensive unit, replacing it will be much more expensive than eliminating the cause of incorrect operation. Among the most common reasons that lead to such a breakdown are the following: Freon leakage.
Short circuit in the control unit. Compressor wear. Thermostat malfunction.
The capillary tube of the evaporator is iced up.

Biryusa 10. The compressor works, does not turn off. The freezer is freezing. Ice builds up in the freezer. The evaporator tubes are slightly cool in the refrigerator compartment. I changed the seals on the doors, I thought they were the case, but everything is the same. What is the problem?

The problem is a partial leak of freon.

Refrigerator Biryusa 133 has been in operation for 6-7 years. In the morning, I noticed that when I tried to turn on, the compressor began to rattle, shake and turn off. I turned it off, touched it in half an hour, the compressor was still hot. They disassembled the relay, see if nothing bad was visible, except for the fact that on RKT 2, where a piece of paper with the name is pasted. From the outside it looks like it's burnt. Maybe turned yellow from
temperature and time, or it is still not working properly. Or does the compressor need to be changed?

Check the compressor. You have a KV-140 compressor (check the sticker on the compressor). Remove the relay and ring the windings, there are THREE outputs in a circle (for 8-12-4 hours). Between 8-12 the starting resistance should be 18.3 ohms + 5%. Between 12-4, the working resistance should be 21.1 Ohm + 5%, at + 25C.

In operation, the Biryusa 127 refrigerator is two-chamber, the upper chamber does not freeze. In the heating element, where the freon should be, the noise is similar to water, and the engine heats up, tell me what to do?

Refrigerators Biryusa 127 models do not have heating elements. According to the technical documentation, these are single-compressor units with a manual defrosting mode of the freezer, a drip defrost system in the refrigerator compartment and one thermostat that simultaneously regulates the temperature in both chambers. The most likely reason why your refrigerator does not freeze is a freon leak. Try to completely defrost the cold-k for a day, and then turn it on again. If both chambers stop freezing, it's definitely a leak. Also, according to the symptoms you described, the cause may be a thermostat, but then in the freezer of this model there should also be malfunctions in the temperature regime, it should be above normal (minus 16 - minus 18 Celsius). It is normal for the compressor to heat up, it will heat up
and with the correct operation of the unit.

Biryusa 18, 1991 year of release. The compressor works for him, does not turn off. The thermostat is set to position “1” (at minimum). The temperature in the freezer compartment is minus 30. The temperature in the refrigerator compartment is plus 12. Where to look for a malfunction?

The most likely cause of the problem is a refrigerant leak. In this case, it is necessary to determine the location of the leak, eliminate it, and charge the refrigeration unit with refrigerant.

Why is there no cold in the refrigerator chamber Biryusa 18c (two-chamber with electromechanical control and one motor-compressor)? The freezer compartment is working properly.

Most likely, the thermostat of the refrigerating chamber is out of order, and it needs to be replaced. This is why it doesn't work. We also recommend defrosting the unit, if both chambers do not work after defrosting, then this is a freon leak in the system.

Biryusa 118 two-compartment refrigerator does not want to freeze. The compressor is not working well. What is the reason for this problem?

There are a number of possible malfunctions that cause incorrect operation of the unit: overheating of the motor-compressor; depressurization of the apparatus; malfunction of the thermal sensor; freon leak; a problem with heating elements - an element of the evaporator in modern units with the No Frost system; malfunction of the thermostat.

Refrigerator Biryusa 133 stopped working, when you plug it in, you hear clicks, lighting and LED sensors work, tell me what can break?

Most likely, the malfunction lies in the motor-compressor.

In the refrigerator turquoise 134 K (single-compressor with a drip defrost system in the refrigerator compartment and manual defrosting in the freezer). The upper chamber does not work (does not freeze). What could be the reason?

The temperature in both chambers is regulated by one thermostat. Possible breakdowns you may have the following: refrigerant leak, try to completely defrost the refrigerator (at least 12 hours, or preferably a day), if after defrosting the freezer also stops freezing, then you have a leak; malfunction of the thermostat that regulates the temperature in the refrigerator.

Biryusa 118 two-chamber, has stopped freezing. There is light, the compressor at first worked without interruption, now it turns on for a couple of seconds and a pause, after 5 minutes it repeats.

The compressor is probably out of order.

From the very beginning of the operation of the Biryusa 122 refrigerator, ice began to freeze. Once thawed for several hours, removed all the water from the freezer, after a couple of weeks the ice reappeared. Tell me what to do?

Everything is in order in the refrigerator compartment. This is the job of a “crying type” vaporizer. Moisture on the rear wall of the chamber in the form of frozen droplets thaws when the compressor is turned off and flows down the drainage system into the melt water tank, where it evaporates due to the heat generated by the compressor. Freezing in the freezer compartment can be caused by the following reasons: 1. You are placing food in the compartment that does not
cooled to room temperature; 2. You often open the MK door, or keep it open for a long time; 3. Probably, the MK door does not fit tightly to the body.

A single-chamber refrigerator Biryusa 10 is in operation. Water does not leave, it accumulates inside it. What can you do yourself without calling the master?

In this case, you will need to clean the drainage system.

When you turn it on for the first time, the Biryusa 18c refrigerator works. If you turn it off and then turn it on, the thermal relay is triggered and then the relay cheeks go. If after a while the compressor is switched on again, it starts. The compressor rang, shows 32-21-53, there is no breakdown to the case. The relay was replaced, although with the old one the same situation. I thought about the thermostat, disconnected the wires, bridged them. The situation is the same.

Reconnecting the unit to the network should be carried out 5-6 minutes after disconnection.

In operation, a two-compartment refrigerator Biryusa 143 with electronic control, one compressor and No Frost in the freezer (2008). How to find out if there is a solenoid valve. And if so, where is he? Maybe in the foam part, because visually it is nowhere to be seen.

The valve in this model can be found at the back close to the compressor.The valve looks like a plastic box that contains 3 copper pipes.

A two-chamber refrigerator Biryusa 18 s (1 compressor) is in operation. The compressor turns on and after 10 seconds it turns off, after 2 minutes it turns on, etc. on this cycle. The relay clicks both on and off. The motor does not hum. What could have broken?

If the motor turns on and off immediately, the motor-compressor may be defective. After turning off, try to touch the compressor with your hand, if the hand cannot be held for 3-5 seconds, then the motor is faulty and it is turned off by the start-up relay.

Turquoise W 127 KLA does not cool well. By thermometer - in the freezer -20; in the refrigerator +14.
The regulator is in the middle position. The radiator is slightly warm. What does that mean?

Refrigerator turquoise 122 stops freezing (it freezes, then it does not freeze). The socket is working. I worked in the evening, water in the morning. Washed, turned on, works. An hour later, it does not work again. Tell me what to do?

Usually such models have a problem with the thermostat.

The Biryusa 133 refrigerator is in operation. The freezer does not work. What to do?

If the freezer does not work, then the thermostat is faulty, or freon is leaking, or the motor-compressor is faulty.

Two-chamber refrigerator Biryusa 134 with one compressor and mechanical control, purchased in 2010. The compressor does not turn off. On the back wall there is a hall. branch has grown a "coat" of ice. The temperature in the freezer is -18C, in the cold. department + 5c. Please tell me if it can be repaired?

If the compressor does not turn off, but there is a "fur coat" of snow in the refrigerator compartment, then the malfunction may be: a freon leak, a breakdown of a thermostat, or a clogged capillary system. Also, we recommend that you check if the sealing gum (seal) is torn anywhere. Due to an incomplete seal, warm air can enter the unit and freeze on the rear wall.

Refrigerator Biryusa 118 stopped freezing and generally buzzed. Tell me what could be?

Most likely, the thermostat is out of order.

Please tell me which thermostat model is needed for a single-chamber refrigerator Biryusa-10 C-1 12.2004? It has a freezer inside, electromechanical control and one motor-compressor.

The TAM-133 thermostat is suitable for your refrigerator.

Two-compartment refrigerator Biryusa 143 with electronic control and Nou Frost system in the freezer (runs on R600 refrigerant). After replacing the motor, the unit works for a long time and does not turn off. The display is set to a temperature of +7, and it cools the refrigerator to +1 and only then turns off. What is the problem?

The so-called "valve refrigerator". Perhaps the solenoid valve is stuck, or perhaps more refrigerant (freon) was charged than needed if a 134 gas compressor was used.

Refrigerator Biryusa 120, the freezer works and freezes well, but in the very cold. the compartment is not, and the back wall is wet.

Probably a freon leak from the system. There is still enough refrigerant for the freezer, because it is small, but the refrigerator is no longer there. We recommend calling the wizard to fix the leak and refill the unit with freon.

In the morning I discovered that the Biryusa 134 refrigerator was not working. The compressor (KV-140) is trying to start, it works as if it is “pedaling” and after 8 seconds it stops. The inscription on the RKT-2 relay turned black a little. There are no fused contacts. Compressor windings do not short to ground. There is no break between the conclusions. Replaced the compressor. For some time he worked without disconnecting. Replaced the thermostat. Began to turn off. But after a couple of days it does not turn off again, the fur coat is frozen inside from above and the case is hot between the doors. What else does he want?

Failure of the first compressor, that is, turn-to-turn circuit due to overheating of the el. compressor motor due to refrigerant leakage. The compressor has been replaced, the cause has not been eliminated.

Malfunctions of Biryusa refrigerators

What are the most common malfunctions? According to the statistics of service centers, the following are the most common breakdowns. The unit runs without stopping. Does not turn on. It freezes badly. It turns off with a noise. These malfunctions are manifested not only in old-style models, but also in fairly new models. The reasons for the breakdown may be different, respectively, and the ways to eliminate them will also differ.

The unit does not turn off - If the x-k does not turn off, then there may be several reasons for such a non-standard operating mode. The door to the hall is not closed tightly. camera. In this case, the compressor is constantly running because it cannot reach the required temperature level. Check the door and the quality of the seal. The room temperature is too high. Or x-k can be installed next to a heat source. In this case, the motor also runs without interruption, trying to lower the temperature to a predetermined level inside the unit.

Damage to the temperature sensor. In this case, the unit freezes very much and does not turn off because the temperature sensor does not give a signal to the control unit that the set temperature level has been reached. Such a malfunction is fraught with a rapid failure of the compressor due to its wear. Replacing the sensor completely solves this problem. Failure of the control unit. In this case, the temperature sensor will transmit the correct signals, but due to damage to the control module, no further commands will be sent to the compressor and it will not turn off. In the first two cases, when the equipment does not turn off, the problem is eliminated on its own without the involvement of specialists. In case of failure of the control module or thermal relay - call the wizard.

The refrigerator does not turn on - If the unit stops working, then there are a lot of reasons for such a breakdown, ranging from a power failure to the device and ending with the failure of various systems. If the xc does not work, check the mains voltage and correct connection (the plug may not be fully inserted into the outlet, the power cord is damaged, and so on).

In the case when he stopped freezing or heats up instead of cold, such types of breakdowns are possible. Refrigerant leaking (capillary damage). As one of the signs - the compressor turns on only forcibly, it gets very hot and does not freeze. Some types of leaks can be seen without special diagnostics. To do this, disconnect the unit from the mains and expand it. If you see a bulge in the back in the foaming area, this is a 100% indicator of a system depressurization. Such malfunctions are eliminated only by specialists.

After the first shutdown, it does not turn on. Most likely, the protective relay has failed or the compressor windings have burned out. This happens if there is a voltage surge in the network. The motor hums but does not turn on. One of the obvious reasons is a jammed compressor. If the compressor is of the linear type, the cables may not be connected correctly. If the two-chamber x-k turns off with noise, then it may be a breakdown of the compressor or physical wear and tear of its components, especially after 15-20 years of operation. In the event of a shutdown with a loud click, there is only one breakdown option - the start-up relay has burned out, which must be replaced.

There are a number of other problems that owners face. Most of them arise due to violation of the rules of operation and through the fault of the user. But many of them can be solved at home (everyday problems). First of all, check the connection of the unit to the power supply, the tightness of the doors of the lower and upper chambers. One of the most common reasons when the unit does not freeze well is incorrect adjustment of the thermostat knob. You can just accidentally hit it while using the appliance, and the compressor will start producing less cold. The simplest solution is to increase the cooling level by moving the knob one or two notches higher.

The refrigerator is two-chamber, made in the form of a floor cabinet. The body of the refrigerator cabinet and door bodies are made of steel sheet with subsequent application of a protective and decorative coating, the inner cabinet and door panels are made of plastic. Polyurethane foam serves as thermal insulation.

On the side wall of the refrigerating chamber there is a block of devices, which contains a T-130 thermostat, a VOK-2 switch and an RN 220-15-1 electric lamp. The lamp automatically comes on when the door is opened and goes out when the door is closed.

The defrosting of the refrigerating chamber evaporator is automatic, during the non-working part of each cycle of the refrigeration unit operation, which is provided using a T-130 thermostat with a positive switch-on temperature and a heater fixed on the rear plane of the evaporator.

The design of the inner cabinet and door panel in the refrigerator compartment allows the height adjustment of shelves and barriers at intervals of 50 mm. The shelves can be removed from the refrigerator compartment by opening the door 90 °. The design of refrigerators provides for the possibility of re-hanging the doors so that they open from right to left. Doorways are sealed with an elastic seal with a magnetic insert. The low-temperature and cold rooms are cooled using sheet-tube evaporators.

Household two-chamber refrigerator BIRYUSA-22 KShD-255 are intended for storing food in a chilled and frozen state, making food ice and cooling drinks at home. The refrigerator can work in the "Freeze" mode.

Rice. 2 Appearance and structure of the Biryusa-22 refrigerator

Rice. 3 Melted water removal scheme

The refrigerator has a number of comfort elements: the possibility of re-hanging doors for right- or left-sided opening, as well as rearrangement of shelves and barriers in height with an interval of 50 mm; limiting the opening angle of the refrigerating chamber door; the presence of a system for automatic defrosting of the evaporator of the refrigerating chamber and removal of melt water outside the refrigerator with subsequent evaporation. The refrigerator is provided with light signaling of operating modes ("Freezing" and "Storage").

The refrigerator is designed as a base cabinet divided into two chambers, each with its own door. In the lower refrigerating chamber, the temperature is maintained at 0. 10 ° C, in the upper low-temperature (freezing) chamber for storing frozen products, the temperature is -18 ° C. The refrigerator is made with a mounting plane; a control and alarm unit is built into its edging, which consists of an operation mode switch that provides two modes of operation of the freezer ("Freezing" and "Storage"), a voltage indicator and a switch for electric heating of the middle bar.

The electric heater of the middle bar is turned on with a switch when condensation (moisture) appears on the front surface of the middle bar. Condensation can occur when the ambient humidity is high. The electric bar heater can remain on all the time. The temperature regime in the refrigerator is set using the thermostat knob. The mode is supported automatically; at the same time, in case of insufficient cooling, the handle is turned clockwise, in case of hypothermia - in the opposite direction. The thermostat handle has a graduation from 1 to 7 (0 - shutdown of the refrigerator). On the side wall of the refrigerating chamber, an instrument block is fixed, which consists of a light bulb, a thermostat and a switch. When replacing a light bulb, the diffuser must be removed.

Not every consumer knows that the repair of any home appliances, including the refrigerator, can be done independently without contacting a service center. Even a novice master can deal with simple breakdowns. Today we will try to figure out how to replace the refrigerator thermostat with our own hands.And also let's talk about what kind of device it is and what are its characteristics and purpose?

First, let's figure out what it actually is. A thermostat is a device that monitors the t˚C in your refrigerator and gives signals to the compressor, causing it to turn on and off depending on the degree of cooling in the compartment. It works very simply. The thermostat is a relay. On one side of it there is a special hermetically sealed tube filled with freon. On the other hand, the contacts of the electrical circuit, with their help, the compressor is controlled.

See also - How to adjust the thermostat (thermostat) in the refrigerator

Everything works very simply. The end of the capillary tube is attached to the evaporator. Since it is filled with a refrigerant, for example, freon, then with an increase in t˚C inside the refrigerating chamber, the pressure in it increases. This closes the corresponding relay contacts and turns on the compressor. After a while, t˚C in the refrigerator compartment decreases, the pressure in the bellows tube drops and the contacts open. The compressor turns off.

Another important component of the thermostat is the spring, which compresses and expands its contacts. It depends on her how and when they will work. For example, in order to open the contacts at a low pressure in the system (low t˚C), less effort is needed, for a large one - more. The tension of the spring is adjusted using the thermostat switch knob. This is how the temperature regime changes in the Atlant refrigerator and other models with mechanical control.

Some models of refrigerators are equipped with an electronic thermostat. It consists of a temperature sensor and a control module. In modern models, several sensors can be installed for each cooling zone. If your refrigerator has an electronic temperature control mode, it may require specialized knowledge to repair it.

Well, we have disassembled the device and characteristics of the device, we move on to the next question. In order to repair the thermostat with your own hands, you first need to find it.

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

inside the refrigerating chamber;
outside the refrigerator.

This arrangement is typical for earlier models of Atlant refrigerators and others. If you open the refrigerator, you can 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 selector knob and unscrew the protective case.

Modern refrigeration units are arranged 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 controller is located in the same place as the switch knob. To get to it, you need to remove all protective parts.

See also - Why does a refrigerator need a voltage regulator

Do we really need a temperature controller? Maybe the cause of the breakdown is completely different? Most often, the signs of a breakdown of a thermostat are obvious: (See also: Why the refrigerator does not freeze - what to do?)

the refrigerator works without stopping and does not turn off on its own;
the unit begins to freeze strongly in the refrigerator compartment, where, in normal mode, there should be, albeit a low, but still positive temperature;
the refrigerator shuts down spontaneously and no longer makes any sounds.

Each of these faults can be caused by the temperature controller.In order not to spend money on calling a specialist, we will try to fix the breakdown with our own hands.

To be sure that the temperature regulator is the cause of the malfunction of the Atlant refrigerator or any other, you need to do the following:

disconnect the refrigerator from the power supply;
remove all food from it and defrost it well;
move the thermostat knob to the “Max” position or turn on the freeze, if any;
place a thermometer on the middle shelf of the refrigerator compartment (not in the freezer), it is best if it also has a negative measurement scale;
turn on the refrigeration unit (empty, no food);
wait 2 hours, then quickly remove the thermometer and evaluate its reading.
On the "thermometer" you should see at least 6-7˚С. If this is not the case, repairs are imminent. And if the thermostat in your refrigerator is electronic, then it is unlikely that it will be possible to carry out repairs with your own hands.

There may be only 3 reasons:

broken thermostat;
the motor start relay has burned out;
the engine of the refrigeration unit burned out.

The last two reasons are, of course, very serious. But we are now interested in the first one. To make sure that you need to replace the thermal relay, you need to check it:

disconnect the refrigerator from the network;
find the location of the thermostat and remove the protective covers;
inspect the device carefully.

Most often, the temperature controller has three to four colored wires. One of them is usually yellow with a longitudinal green stripe. This is grounding. We won't need it, so set it aside to avoid accidentally snagging it. All wires that fit the body of the thermal relay, short-circuit each other directly. If, after turning on the refrigerator, you hear a steady hum of the engine, it means that the temperature regulator is out of order and you will have to replace it with a new one.
By the way, the wires suitable for the thermostat have the following purpose:

orange, red or black - connects the thermostat to the motor;
brown - zero, the wire leading to the outlet;
white, yellow or green - leads to a light indicating that the refrigerator is on;
striped yellow-green - ground.

If you find such a nuisance, several factors may be the reason. So first you need to do all the steps described in the first paragraph. If the thermometer readings were + 6 ° C or less, quickly turn the thermostat adjustment knob until the refrigerator is turned off.
If the refrigerator turns off, everything is in order. Not? It will be replaced. In the event that the refrigerator is turned off, we leave it to work without food for at least 5-6 hours. After that, we begin to mark the time intervals between turning the compressor on and off. For a properly operating refrigeration unit, this period should be approximately 40 minutes. If you did it less, "add" some coldness, that is, turn the switch a little to the right, clockwise.
If everything went well, you can load the groceries. Not? The temperature controller will still have to be replaced.

Do-it-yourself thermostat repair does not take much time. For example, let's take a refrigerator of the Atlant trademark:

remove the cover of the upper hinge and unscrew the bolts under it;
remove the refrigerator compartment door;
further, remove the plug in the refrigerator roof and unscrew one screw (most often it has a built-in hexagon);
we unscrew the screws holding the roof (located at the back) and remove it;
remove the temperature control knob;
take out the temperature regulator by unscrewing 2 self-tapping screws that secure the bracket;
change the node to a new one and perform all actions in the reverse order.

In principle, wherever the thermostat is located, its repair will look about the same:

get to the detail;
disconnect the capillary tube from the evaporator body;
carefully pull it out of the case;
disconnect the relay itself;
carefully insert the new bellows tube and secure it to the evaporator;
connect all the necessary wires and attach the relay in place.

If this is your first time doing this kind of work, take pictures of your every step with your phone or camera. The photos will help a lot when assembling, if you forget what and where was connected.

The only plant in Siberia that has been producing refrigerators since 1960, which did not change the name of the Biryusa brand after the division of the Union's property. There are currently 23 series in production. Single-chamber, two-door, with electronic control and the Know Frost system, refrigerators of high quality at an affordable price are loved by the people. 3-year warranty for household equipment, availability of service centers and reliability of devices - the policy of the company.

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

the compressor runs without stopping;
the motor does not turn on, or turns on for seconds;
the regime does not hold in the cells;
the compressor shuts down noisily.

Each of these signs requires diagnosis, there may be several reasons. Some breakdowns of Biryusa refrigerators are insignificant, and their elimination is possible on our own, others - by a master.

Much depends on the model. It is easier to find and independently eliminate malfunctions in an electromechanical refrigerator with drip defrost. An electronically controlled two-compressor refrigerator with No Frost system is reasonably entrusted to a specialist.

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

The oxidized contacts of the starting winding can become the reasons for the malfunctioning. The thermal fuse represents the spiral and the bimetallic plate in contact. If there is a short circuit in the motor windings, the relay opens the contacts, interrupting the start.

During the start of the motor, the device protects the motor winding from increased current strength, preventing overheating of the windings. After starting, the current decreases, the relay opens.

If a malfunction of the P1 relay of the Biryusa refrigerator is established, it can be repaired by finding the reason:

burning or melting of contacts;
destruction of the integrity of the nichrome spiral;
coil jam or stem problems.

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

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

The most common question asked on the forums is why the temperature in the upper chamber is higher than the task, but everything is in order in the freezer. A common reason for the craftsmen is the lack of refrigerant. But after the diagnosis, other breakdowns of the Biryusa refrigerator may also be revealed:

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

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

An eliminable nuisance is the leakage of condensate into the freezer with freezing of lumps. The reason is a blocked condensate drain from the refrigerator. It must be defrosted and cleaned from trapped crumbs and packaging. Water in the refrigerator compartment indicates a clogged hole, and when the water has nowhere to go, it gradually gets into the freezer through leaks.

If the lighting in the cell is gone, the light bulb is in good order, or the refrigerator occasionally shocks - a revision of the electrical wiring is required - somewhere the insulation of the wires is broken.

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 terms of technical parameters. An increase in temperature in the chambers is indicated by a light indication, and an open door is indicated by a sound signal.

Malfunctions are associated with the failure of sensors and relays. It is important that any Biryusa refrigerator is connected through a voltage stabilizer, but for electronic control, unstable power is the main reason for failure. Of the faults - most often the control unit fails. Block failure is clearly defined if there is no response to commands. After pressing the "Stop" button for 5 seconds, the board 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 skewed. The structure is heavy and the brackets are weak for it. But the warranty for the device is 3 years, all remarks are eliminated by the service department free of charge.

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

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

The main causes of malfunctions are considered;

temperature sensor failure;
malfunction of the starting relay;
freon leak;
clogged drain hole and tubing.

If the refrigerator or minus chamber does not work, 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 the failure of the defrost thermostat, the drain pipe 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.

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

Frequently, the loss of cold is due to a malfunctioning thermostat. Breakage is accompanied by signs:

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

The purpose of the thermostat is to read the readings of the sensors 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. Failure of the starting relay or compressor malfunction is determined by a specialist.

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

The cause of ice freezing in the refrigerating chamber may be a malfunction of these units or the influx of fresh air through the door leaks.The diagnostics for models 18 and 18 C are the same. They are distinguished only by their appearance. The refrigerator does not work - see how to carry out diagnostics and repairs in the video.

Refrigerator Biryusa 22 has two doors, the freezer is located on top. There are two working positions on the installation panel - "Storage" and "Freezing". The control unit has a voltage indicator and a switch for heating the middle bar. The temperature in the chambers is set by a common regulator with a graduation in 7 positions.Only some problems associated with improper installation of the device or contact of the tubes with the housing and other assemblies can be eliminated on our own. They can be slightly diluted or put on soft pads. Tighten the bolts. Check if the installation of the refrigerator complies with the instructions for use. If a smell occurs, wash and ventilate the chamber, replace the burnt out light bulb. Wizards are called when unrecoverable problems have arisen.Typical malfunctions of the Biryusa 22 refrigerator:

The electrical wiring is broken, the current passes through the body, the light in the chamber does not light up. Here, the voltage in the network, contacts with terminals in the relay, and the resistance of the windings are checked.

Thermostat is defective. The reasons are a breakdown in the electrical circuit or a malfunction of the bellows tube, but the thermostat must be changed in any case.

Defective compressor or starting relay.

Refrigerant leaking or capillary blockage.

If a fur coat grows on the evaporator, the heater does not work, the reason is in the thermostat or a malfunction of the device itself.

The heater on the partition does not work, the condensate does not evaporate.

The Biryusa refrigerator has been working for 22 decades without breakdowns, if the manufacturer's requirements are met. It must be remembered that the device will not cool well if the room temperature is below +16 and above 35 degrees, the room has high humidity. This is not considered a breakdown, the climate class of the device is N.

Refrigerators Biryusa are reliable in operation. The main problematic unit is the thermostat. The devices do not have protection against a drop in the power supply; they should be connected through a voltage stabilizer.
