Refrigerator turquoise 6 DIY repair

Details: refrigerator turquoise 6 DIY 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.

Good day to all!

although the question is not about sound engineering, and not about the topic of the forum, I know that here we have people from different fields and with a good baggage of knowledge in different fields

so here's what help is needed:
one of the refrigerators went on strike, turquoise 6

it was so, there was a lot of frost on the evaporator (well, or snow to someone else), it stood for a long time, worked, the compressor started and turned off, really hard.
In short, there was a lot of frost, and I decided to turn it off to clean it so that it would all thaw.
washed mlyat.

now the symptoms and the operation of the refrigerator are as follows (such as the chronology of events):
1) I checked (not a cartoon, just visually) the starting and current-protective relay (P1 stands), not the insides, from above everything, again visually, the junction points of the contacts are normal.
2) plug into the socket, the compressor turns on
3) less than a minute passes - the compressor turns off, while you can hear how the refrigerant starts to flow (at least it seems to me that the sound of this particular phenomenon)
4) after a minute, another attempt to start the compressor, again less than a minute and then turn off again, while an extraneous short noise is heard in the starting relay (I think the protection is triggered).
5) after a minute, another attempt and again less than a minute and it turns off and again the coolant is heard
6) I feel the condenser - warm, I feel the freezer - cool
7) I feel the compressor - decently hot.

total thoughts in the ear-
or while defrosting, it violated the sealing and the refrigerant leaves, but if the condenser is warm in three attempts to turn on, and the evaporator becomes cool, I slowly cut off this thought.
second thought - the thermal relay drives.

In short, who has any other thoughts in the ear, but more.
and in general if anyone knows what kind of thermostats are there and where can you try to look for them?
Is it worth changing the starting relay too?
and how to check the first option with a refrigerant leak? except for a device? (Of course, the elimination method is also good, but the cost.)
and I also think to put the varistor in the plug (it will just fit there), for example 471 by 14, is there any point?

Question: I have a 1985 Honda Accord, B18A engine, CA2 body. So, something started to junk carb - does anyone have a diagram of its device or something similar. Thanks a lot in advance!

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.From time to time, any equipment fails and begins to require repair. Refrigeration equipment Biryusa is of high quality and durability, but, even it, periodically forces the owner to contact a specialized workshop or visit a service center.

How to repair a Biryusa refrigerator?

Of course, there are situations when the problem can be corrected with your own hands, but, even in this case, an electrical diagram of the unit may be required. To find it, you can use the resources of the Internet, or ask for help from the masters.

As a rule, each technique has a certain list of faults that are specific to it. All Biryusa refrigerators can operate stably for a long period of time. But, unfortunately, they are also not insured against breakdowns. Here is a list of the most common problems:

during engine operation, extraneous sounds are heard that are not characteristic of the normal operation of the unit;
an unpleasant odor appears inside the refrigerating chamber, which cannot be eliminated either by complete defrosting or thorough cleaning of the entire chamber;

lighting has disappeared and the problem cannot be solved by replacing the light bulb;
it seems that the electrical wiring closes;
the refrigeration unit simply refuses to turn on;
the motor-compressor works, but does not cool at all;
while the compressor is running, the evaporator starts to cool;
the motor-compressor stopped turning off;

an ice coat constantly appears on the walls of the evaporator;
moisture condenses on the partition separating the door.

It is worth noting that this or that breakdown does not necessarily require significant financial costs.In most cases, the malfunctions are justified by the failure of any sensors, sensors or relays, which means that it is enough to simply replace the inoperative element and the Biryusa refrigerator will start to function stably and smoothly again.

It is no secret that some problems that can interfere with the full operation of the Biryusa refrigerator can be easily eliminated with your own hands, without seeking help from specialists. Most often, these problems are associated with incorrect installation of the refrigeration equipment itself, improper care and power supply problems.

In most cases, repairing refrigeration equipment requires contacting a qualified technician. The only exceptions are those situations when the owner himself has the appropriate skills and knows how to read diagrams. Let's consider a few of the most common causes of the malfunction and how to fix them.

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

Incomplete thawing of ice during the previous defrosting or lack of defrosting for a long time. To eliminate it, it is necessary to disconnect the unit from the mains, defrost it, wash it and wipe it dry. It is also recommended to leave the refrigerator open for 1-2 hours for ventilation. After that, you can turn on the refrigerator to the network;

The work cycle was broken. The problem may be that the capillary tube of the temperature controller is simply squeezed out of the seat. To eliminate, you should return this tube to its rightful place;
The motor-compressor does not turn off in time. In this case, the temperature regulator is out of order. To fix the problem, the thermostat needs to be replaced.

The refrigerator continues to work, but has stopped freezing:

Freon leakage as a result of microcracks in the pipeline, depressurization of the seams. It is necessary to eliminate the leak, then fill in freon dosed and observe the functioning of the refrigerator;
Damage to the freezer compartment as a result of improper cleaning and damage caused by incorrect transport of the unit. In this case, only replacing the freezer will fix the problem.

The camera light works, but the refrigerator has stopped freezing:

The starting relay of the motor-compressor is out of order. To eliminate this problem, it is necessary to replace the corresponding relay;
The thermostat stopped working. Eliminated by replacement;
The electronic unit has ceased to function. To eliminate the problem, it is necessary to repair the unit in a special workshop or service center;

There are faults in the electrical wiring. To eliminate the malfunction, repair of all electrical wiring is required.

The refrigerator turns on, but after 2-5 seconds it turns off:

The mains voltage is insufficient for normal operation. Eliminated by installing a stabilizer;
Problems with the starting relay of the motor-compressor (weak or oxidized contact). To eliminate the problem, you need to clean the contacts or replace the relay itself;
The electronic unit is not working correctly. It is necessary to make repairs, or completely replace the unit;
The appearance of an interturn short circuit in the windings of the motor-compressor. Eliminated by replacing the motor-compressor;
Problems with the wiring. To fix the problem, it is necessary to check all wiring, connections and chips for weak or burnt contact;
Incorrect transportation. In this case, it requires a complete diagnosis of the refrigerator. It is likely that the unit itself will need to be changed.

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.
