Searching for a thermostat in two-compartment refrigerator Atlant often becomes the first step in diagnosing problems with temperature conditions. If your appliance has stopped freezing or, on the contrary, turns food into ice blocks, the reason may lie in this small but important control element. Understanding where the thermostat is located will allow you to independently conduct an initial inspection and decide whether to call a specialist.
The design of Belarusian-made refrigerators has its own characteristics that distinguish them from many European analogues. In most models Atlant the thermostat is hidden inside the case, which requires careful dismantling. It is important not to damage the insulation and plastic latches, which can become fragile after prolonged use at low temperatures.
In this article we will examine in detail the architecture of the refrigeration chamber, methods of access to the control device and nuances that are often overlooked during self-repair. The exact location of the sensor directly depends on the series of your refrigerator and the year of its manufacture. Be careful, as an erroneous determination of the installation location can lead to unnecessary damage disassembly.
Design features of Atlant thermostats
Thermostat, or thermostat, in refrigerators Atlant performs the function of the “brain” responsible for turning it on and off compressor. In two-chamber models, this element is most often located in the upper compartment, where products that require refrigeration rather than freezing are stored. Mechanical models, which were installed in the technology of previous years, have a long capillary tube that goes deep into the evaporator.
Modern modifications can be equipped with electronic control systems, where the temperature sensor is a small resistor hidden in a plastic casing. However, the classic mechanical thermostat is still widespread in everyday life. Its body is usually hidden behind a decorative panel or directly mounted into the chamber wall.
⚠️ Attention: Before any manipulations with the electrical components of the refrigerator be sure to disconnect the device from the network. Working with live wiring is deadly.
Understanding the operating principle helps you find the node faster. The capillary tube responds to changes in gas pressure inside it by closing or opening contacts. If you see the temperature control knob, the mechanism itself is located immediately behind it, inside the case.
What is the difference between thermostats of different series?
Mechanical thermostats of the TAM and T-133 series have different lengths of the capillary tube and type of fastening. Installing an unsuitable model can lead to incorrect operation of the compressor or its constant inclusion.
Where to look for a thermostat in classic models
In classic two-chamber refrigerators Atlant with a top freezer, the thermostat is most often hidden in the upper right corner of the refrigerator compartment. To get to it, you need to remove the plastic cover that covers the lighting lamp and the lampshade. This is a standard scheme for most models released before the full implementation of the No Frost system.
The access process usually looks like this: carefully pry up the lamp diffuser, unscrew the screws holding the control unit. The element you are looking for is hidden under this block. Sometimes, for a full view, it is necessary to move or partially dismantle the top shelf if it interferes with the view.
- 🔍 Inspect the upper right corner of the refrigerator - this is the most likely place.
- 🔧 Look for hidden screws under decorative plugs or behind the lamp shade.
- ❄️ Pay attention to the corrugated tube going from the regulator deep into the wall.
- 🧊 Check for the presence of a plastic cover that hides the electrical contacts.
In some modifications, the thermostat may be shifted closer to the center of the upper wall. If you removed the lamp shade but did not see the regulator, try carefully removing the top decorative panel of the refrigerator compartment. It can be attached to latches that require careful handling.
Location in models with the No Frost system
Refrigerators Atlant equipped with the system No Frost or “Crying Evaporator” have a more complex internal architecture. Here the thermostat is often hidden behind the back wall of the refrigerator compartment or in a niche above the freezer compartment. Access to it may be limited by massive air ducts and a cold air circulation system.
To find the sensor in such models, partial disassembly of the internal space is often required. All shelves, drawers and decorative panels must be removed. The back wall in refrigerators with automatic defrosting is sometimes part of the evaporator, and extreme care must be taken when accessing the thermostat so as not to damage the cooling circuit.
In models with electronic control, temperature sensors can be built directly into the air ducts. In this case, you will not see the usual “twist” inside the camera, since control is carried out through the display on the outer door. In this case, the internal sensor is a small element secured with a clamp to a metal tube.
⚠️ Attention: In No Frost refrigerators, the back wall can be very fragile. Do not use excessive force when removing it, so as not to break through the freon channels.
Diagnostics of thermostat malfunctions
Before you start disassembling, you should make sure that the problem lies in the thermostat. Symptoms may be similar to a compressor failure or freon leak. The main sign of a malfunction thermostat is the lack of cyclical operation of the compressor: it either works without stopping or does not turn on at all.
If the refrigerator Atlant hums continuously, and the food in the refrigerator compartment freezes, most likely the contacts the regulator is “stuck” in the closed state. Conversely, if the equipment is silent and it’s warm inside, the contacts might not close. A simple jumper test allows you to check the hypothesis without completely replacing the part.
| Symptom | Probable cause | Action |
|---|---|---|
| The compressor does not turn on | Open circuit thermostat | Checking contacts with a jumper |
| The refrigerator does not turn off | Sticking contacts | Replacing the thermostat |
| Weak cooling | Incorrect calibration | Adjustment with a screw or replacement |
| Sparking inside the camera | Short circuit | Urgent disconnection from the network |
Also It is worth paying attention to the adjustment knob. If it scrolls freely, without characteristic clicks, or, conversely, is jammed, this is a direct indication of mechanical damage to the internals of the device. A visual inspection of the wires going to the unit is also mandatory: they should not be melted or cut through.
Instructions for replacing the thermostat
If the diagnostics confirmed a malfunction, it is necessary to replace it. For the job you will need screwdrivers (Phillips and flat head), pliers and possibly a multimeter to check. The new thermostat should have markings identical or as close as possible to the original, especially along the length of the capillary tube.
First, disconnect the old regulator from the electrical circuit, remembering or photographing the color markings of the wires. Then carefully pull the capillary tube out of its seat. Be careful: the tube is thin and easily breaks, and the contents are under pressure.
☑️ Procedure for replacing the thermostat
Installation of the new element is carried out in the reverse order. The capillary tube of the new thermostat must be carefully inserted into the same hole, without bending it at an acute angle. After connecting the wires and assembling the plastic panels, you can turn on the refrigerator and monitor its operation for several hours.
⚠️ Attention: Do not try to repair the thermostat itself (soldering, opening the case). This is a disposable element that can only be completely replaced.
Common mistakes during self-repair
The most common mistake is incorrect identification of the thermostat model. Visually, they may be similar, but differ in the temperature range of operation. Installing an inappropriate regulator will lead to the refrigerator either undercooling the food or working for wear.
Another mistake is damage to the capillary tube during installation. If you accidentally break the tube or damage its insulation, gas will escape and the thermostat will stop responding to temperature. It is also not recommended to use “non-original” fasteners or electrical tape where factory clamps should be.
Ignoring electrical safety rules is a critical risk. Even if the refrigerator is unplugged, a charge may remain in the capacitors, and careless handling of the wires while the power is on during testing may result in electric shock. Always double-check that there is no voltage before touching the contacts.
Questions and answers (FAQ)
Is it possible to temporarily close the thermostat to make the refrigerator work?
Yes, if you connect the wires going to the thermostat, the compressor will start and run constantly. This will allow you to temporarily preserve food, but you cannot use the refrigerator in this mode for a long time, since it will not turn off and may overheat.
Where to buy an original thermostat for Atlant?
Original spare parts are best purchased in specialized household appliance stores or official service centers Atlant. When purchasing, pay attention to the markings and length of the capillary tube.
Why doesn’t the new thermostat click?
Some modern electronic or specific mechanical thermostats can operate silently or make a very quiet click. If the refrigerator begins to freeze and turns off in a cycle, then the device is working properly, regardless of the sound.
How much does it cost to replace a thermostat with a specialist?
The cost consists of the price of the spare part and the work of a specialist. On average, the service is cheaper than buying a new refrigerator, but more expensive than replacing it yourself if you have the skills.
