Where is the thermostat located in single-chamber, double-chamber refrigerators Atlant
In modern models, the concept of “thermostat” is supplemented with new technological terms. The role of a thermostat here is played by temperature sensors, which would more accurately be considered motivator elements in an electronic processor for controlling and even programming the operation of the refrigerator.
If in classic products the handle is located in the same place as the regulator, then in the new refrigerator manufacturers can place the electronic control module anywhere. The most likely place to locate the thermostat is the refrigerator door. It is easy to get to the object by removing the inner plastic door panel. We emphasize again the importance of maintaining the integrity of the rubber seal, latches and other fastening parts.
Thermal sensors are placed in different chambers of the refrigerator separately, since the control process for each of these chambers occurs individually. Separate sensors send a signal to turn on the heating element of the quick defrosting system.
They also often fail, which leads to malfunctions of the electronic control module. Timely replacement of the temperature sensor in the refrigerator is very important. As a result of failures, it is often necessary to “reflash” the processor’s RAM. This operation requires a special computer program and firmware codes.
In principle, no matter where the thermostat is located, its repair will be approximately the same:
- get to the details;
- disconnect the capillary tube from the evaporator body;
- carefully pull it out of the body;
- disconnect the relay itself;
- carefully insert the new bellows tube and securely fasten it to the evaporator;
- connect all the necessary wires and attach the relay in place.
About the work procedure
To replace the thermostat in the Biryusa refrigerator, the technician needs to disassemble the outer shell of the device to get to the required part. Usually the body and the top cover are dismantled, under which the required 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 the lighting unit in the Biryusa 3 refrigerator 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.

Rules for dismantling the thermal relay
If the refrigerator does not turn on at all, it will be impossible to carry out the diagnostics described above. The probable cause of the breakdown is an electrical failure of this element.
But a problem can also be a compressor malfunction, for example, a burnt out motor winding. To determine whether the thermostat needs to be replaced, it will have to be removed from the refrigerator for examination.
First you need to unplug the refrigerator. Now you should find the place where it is located, as described earlier. Usually you need to remove the adjustment knob, remove the fasteners and remove the protective elements.
Then you need to carefully inspect the device, paying close attention to the wires through which the power is supplied.
All of them have different color markings depending on their purpose. Typically, a yellow wire with a green stripe is used for grounding. This cable should be left alone, but all the others should be disconnected and shorted together.
Now the refrigerator is plugged in again. If the device still does not turn on, the thermostat is probably working properly, but there are serious problems with the compressor.
If the engine starts working, we can clearly conclude that the relay needs to be replaced. Before starting work, it doesn’t hurt to arm yourself with a smartphone or camera in order to consistently record all operations. When installing a new thermostat, these pictures can be very helpful, especially for beginners.
You need to clearly remember which cable core was used for what purpose. Typically, a black, orange or red wire is used to connect the thermal relay to the electric motor. A brown wire leads to zero, a yellow-green wire provides grounding, and a pure yellow, white or green wire is connected to an indicator light.
Sometimes removing a damaged regulator can be difficult, especially when it is placed outdoors. For example, in some Atlant refrigerator models you have to completely remove the chamber door from its hinges. To do this, you need to remove the trim that is installed above the top hinge and unscrew the bolts hidden under it.
How to check the thermostat in single-chamber, double-chamber Atlant refrigerators before replacing
Before replacing the thermostat, it is recommended to check its operation. The test procedure depends on the detected signs of malfunction. If the refrigerator operates continuously and the motor does not stop, you need to perform the following steps:
- disconnect the refrigerator from the power supply and remove all food from the chamber;
- switch the temperature control knob to the coldest mode or turn on the quick freezing function (if equipped);
- leave a thermometer on the central shelf of the chamber that can measure negative temperatures;
- run the refrigerator and leave for 2-3 hours;
- remove the thermometer and check the temperature - it should display 6-7 degrees, and if there is a strong deviation, the thermostat needs to be replaced.
To simplify the check and not waste a lot of time, you can get to the thermostat and move the plate to the sides, which is located near the pin that holds the handle. If no clicks are heard when the plate moves or it remains motionless, replace the thermostat.
How to find out if the thermostat is broken?
Users of Biryusa refrigerators are generally satisfied with the quality of these devices. But any technique fails. How do you understand that the thermostat is broken and needs to be replaced? You need to pay attention to the functioning of the freezer and refrigerator compartment. If the Biryusa 18 s model has one temperature regulator, both chambers will fail at the same time. Otherwise, the compartment in which the temperature regulator has broken down will not work.
Model Biryusa 18
The second, clear sign that the thermostat in the Biryusa 3 refrigerator is broken 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 a broken thermostat leads to an increase in temperature.

The operating principle of the thermostat in Atlant refrigerators
First, let's figure out what it actually is. A thermostat is a device that controls the temperature in your refrigerator and sends signals to the compressor, causing it to turn on and off depending on the degree of cooling in the chamber. It works very simply. The thermostat is a relay. On one side there is a special hermetically sealed tube filled with freon. On the other hand, there are electrical circuit contacts, with their help the compressor is controlled.
It all works very simply. The end of the capillary tube is attached to the evaporator. Since it is filled with a refrigerant, for example, freon, when the t˚C rises inside the refrigeration chamber, the pressure in it increases. This closes the corresponding relay contacts and turns on the compressor. After some time, the t˚C in the refrigeration compartment decreases, the pressure in the bellows tube drops and the contacts open. The compressor turns off.
Another important component of the thermostat is a spring that compresses and releases its contacts. It depends on her how and when they will work. For example, in order to open contacts at low pressure in the system (low t˚C) less effort is needed, for high pressure - more. The spring tension 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 refrigerator models have 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 electronic temperature control, repairing it may require specialized knowledge.
Signs of malfunctioning thermoregulation in the refrigerator
Refrigerators, like other household appliances, are not immune to breakdowns. Regardless of the specific manufacturer, refrigeration equipment fails. Any part in the units can break, but often the reason for the lack of normal functioning of refrigeration equipment is a malfunction of the thermostat. When the thermostat fails, there are two main manifestations that signal this - a non-working chamber and a malfunction of the compressor.
When the refrigerator has two or more chambers, the temperature in the compartment whose thermostat is faulty will rise or the thermometer readings will be excessively low. Interruptions in the operation of the motor-compressor are the result of incorrect signals supplied by the temperature control sensor. In this case, the engine operates regardless of the actual temperature inside the compartments or does not work at all. This is due to the fact that a faulty thermodetector is not able to adequately assess the temperature and sends a signal to either the compressor to work continuously or not to work at all.

What indicates a breakdown of the thermostat in Atlant refrigerators
Do we really need a temperature controller? Maybe the reason for the breakdown is something completely different? Most often, the signs of a thermal relay failure are obvious:
- the refrigerator runs non-stop and does not turn off on its own;
- the unit begins to freeze very much in the refrigeration compartment, where in normal mode there should be a low, but still positive temperature;
- The refrigerator switches off spontaneously and no longer makes any sounds.
The cause of each of these malfunctions may be the temperature controller. In order not to waste money on calling a specialist, we will try to fix the breakdown ourselves.
Atlant refrigerator does not turn off by itself
To make sure that the temperature controller is the cause of the malfunction of the Atlant refrigerator or any other, you need to do this:
- disconnect the refrigerator from the power supply;
- remove all food from it and defrost well;
- move the thermostat knob to the “Max” position or turn on the freeze, if available;
- Place a thermometer on the middle shelf of the refrigerator compartment (not in the freezer), it is best if it has a negative measurement scale;
- turn on the refrigeration unit (empty, without food);
- wait 2 hours, then quickly remove the thermometer and evaluate its readings.
On the thermometer you should see at least 6–7˚С. If this is not the case, repairs are inevitable. And if the thermostat in your refrigerator is electronic, then it is unlikely that you will be able to carry out the repair yourself.
The Atlant refrigerator turns off and is silent
There can be only 3 reasons:
- The thermostat is broken;
- the engine start relay has burned out;
- The refrigeration unit motor burned out.
The last two reasons are, of course, very serious. But we are now interested in the first one. To make sure that it is the thermal relay that you need to replace, you need to check it:
- unplug the refrigerator;
- find the location of the thermal relay and remove the protective covers;
- inspect the device carefully.
Most often, the temperature controller has three or four different colored wires. One of them is usually yellow with a longitudinal green stripe. This is grounding. We won't need it, so put it aside so you don't accidentally snag it. Connect all wires that fit into the thermal relay body directly to each other. If, after turning on the refrigerator, you hear a steady hum from the engine, it means that the temperature controller has failed 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, wire leading to the socket;
- white, yellow or green - leads to a light indicating that the refrigerator is on;
- striped yellow-green - grounding.
The appearance of a snow coat in the refrigeration chamber of the Atlant refrigerator
If you find such a problem, there may be several factors causing it. So first you need to do all the steps described in the first paragraph. If the thermometer reading was +6˚C or less, quickly turn the thermostat adjustment knob until the refrigerator turns off.
If the refrigerator turns off, everything is fine. No? It is due to be replaced. In the event that the refrigerator turns off, leave it to work without food for at least 5–6 hours. After this, we begin to note the time intervals between turning on and off the compressor. For a properly operating refrigeration unit, this period should be approximately 40 minutes. If you get less, “add” the cold a little, that is, turn the switch a little to the right, clockwise.
If everything went well, you can load the products. No? The temperature regulator will still have to be replaced.

Warning: I am not a master and this was my first time doing this! I consider this post useful, since the salary remained the same (or even less), but the equipment has doubled in price and become less accessible.
My refrigerator is about 13 years old and it started to freeze. Half a year ago I replaced the seal, things got better.
Now the choice is yours, you can watch the video or read the photo with a description:
At the moment, the refrigerator has begun to respond to adjustments and the compressor does not thresh constantly.
Reliable technology and good luck to everyone!

Up to minus 50... arrived yesterday from China. I’ll set it for myself
It’s probably easier to buy this one for 360 rubles: ru.aliexpress.com/item/W3…=a2g0s.9042311.0.0.ijAxbm maybe someone will need a link to the thermostat
I think it is without protection against restarting. Mine with protection
On the ZIL refrigerator everything is much easier to change, I changed it a couple of times)
How did you change the seal and where did you get it?
If you're interested, here it is.
Yeah. For specialists, entry into the “foam zone” is very expensive. Well done! Good luck!
That's what I thought too.
Which store did you buy it from?
DaromByt on Lermontova
And I told my family that it’s not a good idea to keep the refrigerator lid open for a long time. It helped)). If something breaks and I can’t fix it myself, I call the specialists. They find a breakdown and name the cost of repair. I refuse, citing lack of finances, pay them for diagnostics, and go to the market to purchase a spare part.
Maybe because of this, but children don’t care))))
Test. And who knows how long the coolant should be threshed before the first shutdown of the compressor after such a repair?
I also installed a Chinese thermostat in the old Biryusa at the dacha three years ago and placed the sensor on the side wall inside next to the “wailing wall”. The compressor started working as expected, but the temperature still did not allow storing anything for a long time. The soup went sour after a few days. The freezing inside could not be stopped. I decided to put a 120 case cooler from the computer inside, on top, at the very back wall. Now the freezing has passed in a few days and the temperature remains strictly 2-4 degrees. I connected the cooler from an old 10 volt adapter to constant operation. It is practically inaudible, but it blows across the weeping wall and creates air circulation in the refrigerator compartment. This is the second year I’ve been using this lifehack and I’m happy as an elephant. If anyone is interested, I can post photos later. I'll be at the dacha in a couple of hours and can take a photo
Do-it-yourself thermostat repair in Atlant refrigerators
In most situations, repairing the thermostat does not make sense, since only replacing the component can completely eliminate the malfunction. At the same time, there are modern types of refrigeration equipment with electronic thermostats that are subject to repair. Such thermostats consist of a temperature sensor and a control module.
There are also models with multiple sensors designed for different cooling areas.
Repair is possible if the relay elements that need to be replaced are damaged. It is carried out like this:
- Gain access to the temperature sensor. Sometimes this requires removing the upper chamber door. To do this, remove the hinge cover and unscrew the screws. Before dismantling the adjusting handle, remove the plugs and unscrew the bolts. All actions are performed carefully, keeping the fasteners in a small box.
- The sensor attached to the bracket is removed by unscrewing the screws.
- If the regulator is located in the main chamber, you need to remove the protective cover of the lighting system. After removing the bolts, the sensor is removed from the seat.
- Inspect the item. Sometimes it does not work correctly due to a broken bellows (capillary tube). This part can be replaced, eliminating the need to dispose of the relay.
- The bellows is disconnected from the condenser and removed from the thermostat housing. Install a new tube, connect it to the evaporator, and assemble the relay. The sensor is inserted into the seat. Reassemble the refrigerator in the reverse order.
About the location
Thermostats in Biryusa refrigerators are located in different places in the device depending on the model. Experts say that this element can be located:
At first glance, replacing the thermostat in the Biryusa 22 refrigerator may seem simple. However, it is better to entrust this work to professionals. You need to understand right away that the thermostat cannot be repaired. It only needs to be replaced with a new one.
