Refrigerators Atlant for many years they have remained one of the most popular on the market due to their reliability and affordable price, however, even the most proven equipment over time requires attention to temperature control. The main element responsible for maintaining cold is thermostat, which controls the operation of the compressor, turning it on and off when the specified parameters are reached. Owners are often faced with the need to find this unit for replacement or diagnostics, but its location greatly depends on the specific series and year of manufacture of the device.
The search for this element may not be obvious, since manufacturers often hide it behind decorative panels or disguise it as general controls. Understanding where exactly in your Atlant model is the thermostat locatedwill save you time and avoid damage to plastic fasteners during dismantling. In this article we will analyze in detail all possible options for the location of sensors for different modifications.
Before you begin disassembling, you need to accurately determine the type of control of your refrigerator, since the physical location of the control unit depends on this. Mechanical systems require searching directly for the thermostat, while electronic models use sensors integrated into the overall control circuit.
Types of control systems and their impact on the search
The first step in the search is to identify the control system, since this directly determines where exactly you will have to look for the control mechanism. In refrigerators Atlant there are two main systems: mechanical, where a classic thermostat with a bellows tube is used, and electronic, where the temperature is controlled control module based on the readings of temperature sensors.
Mechanical models, usually older or budget ones, have an adjustment knob inside the refrigerator compartment, which is directly connected to the thermostat. In such devices, the device itself is most often hidden under a plastic cover or built into the housing, and it goes into the evaporator. Electronic models do not have a mechanical handle inside the chamber, the control is placed on an external panel, and the temperature sensors are located directly in the cooled space. capillary tube goes to the evaporator. Electronic models do not have a mechanical handle inside the chamber, the control is placed on an external panel, and the temperature sensors are located directly in the cooled space.
⚠️ Attention: An attempt to replace a mechanical thermostat with an electronic analogue without reworking the entire control system is impossible and will lead to equipment failure.
You can determine the type of your model by the presence of a display on the outer door or a characteristic twist handle inside. If you have a model with “no-frost” or a full system No Frostelectronic sensors are most often used, although there are also hybrid options with mechanical control of the dampers.
Location in models with mechanical control
In classic models Atlant with mechanical control thermostat most often located inside the refrigerator compartment. This is a standard solution that allows the sensor to respond directly to changes in air temperature. Usually it is hidden under a special plastic cover located in the upper corner of the camera, or is built into the light control unit.
To gain access to the unit, you often need to remove the lighting cover or carefully snap off the decorative panel behind which the adjustment knob is hidden. In some series, for example, in older two-chamber models, the thermostat may be located behind the rear wall of the refrigerator compartment, which requires partial disassembling the housing and removal of thermal insulation.
Access to the adjusting screws or the thermostat housing itself is opened after dismantling the protective cover. Be careful with plastic latches, as they become fragile over time and can easily break if handled carelessly.
- 🔍 Upper corner: The classic place is under the lamp shade or next to it in the upper right corner.
- ❄️ Evaporator: In models with manual defrosting, the thermostat can be mounted directly on the wall evaporator.
- 🔧 Rear wall: In some modifications, access is achieved by removing the rear panel inside the chamber.
Specifics of Atlant electronic models
In electronically controlled refrigerators the situation is radically different, since the classic mechanical thermostat is replaced here by thermal sensor (thermistor). These elements are small devices whose resistance changes depending on the temperature, and they transmit data to the main electronic control unit.
Sensors in such models Atlant are usually located in special technological holes on the back wall of the refrigerator or freezer. There may be several of them: one controls the air in the chamber, another controls the temperature of the evaporator for the system No Frost, and the third can monitor the temperature in the freshness zone.
To replace or check such sensors, it is often necessary to remove the rear plastic panel inside the chamber. Unlike mechanical models, there are no long capillary tubes, and the connection is made through connectors, which simplifies diagnostics, but requires knowledge in the field electronics.
| Sensor type | Location | Function | Resistance (at 25°C) |
|---|---|---|---|
| Air sensor | Upper part of the rear wall | General temperature control | ~2.2 kOhm |
| Evaporator sensor | Behind the evaporator panel | Defrost control (No Frost) | ~6.6 kOhm |
| Freezer sensor | Inside the freezer | Freeze control | ~5.0 kOhm |
| Fresh zone sensor | In the lower compartment (if equipped) | Maintaining 0°C | ~2.2 kOhm |
⚠️ Attention: Electronic sensors are sensitive to static electricity, so it is recommended to use antistatic gloves when working with them.
Access to the thermostat in the KShD and series KSD
Series Atlant KSD and KSD are among the most widespread, and they use time-tested solutions for placing the thermostat. In most two-chamber models of these series, the thermostat is located inside the refrigerator compartment, which makes it easier to service without completely disassembling the unit.
Most often it is located in the upper right corner, hidden under a decorative cover, which can also serve as an egg holder or simply cover the technological hole. To gain access, you must carefully pry the cover with a flat screwdriver, being careful not to damage the paintwork.
In some modifications of these series, especially the newer ones, the thermostat can be combined with a light control unit. In this case, when you turn the knob, you change the position of the contacts, which control not only the compressor, but also the cameras. lighting. Secrets of removing the thermostat cover. The cover is often held on by two latches. Don't pull it towards you harshly. It is better to insert a thin blade of a knife into the gap between the lid and the wall and carefully turn it to unclick the latches one by one. cameras.

Features of placement in single-chamber refrigerators
In single-chamber refrigerators Atlant (MXM series) the design is simpler, but finding a thermostat can be no less confusing due to the compactness of the case. Here, the thermostat is also most often located inside the chamber, but due to the lack of a separate freezer door, access to it may be limited to shelves or trays.
In older models with a “crying” evaporator, the thermostat can be installed directly on the front panel of the evaporator. The capillary tube in such cases is secured with special clamps, and its damage during careless disassembly will lead to leakage of freon.
If the adjustment knob is brought out to the front panel (which is rare, but occurs in retro models or specific series), then the mechanism itself will be located behind this panel, requiring removal of the entire facade refrigerator for replacement.
- 🧊 On the evaporator: Direct contact with the cooling surface for precise control.
- 🚪 Behind the front panel: In rare cases, the regulator is moved outside.
- 💡 In the light block: Combined placement in the upper part of the chamber.
Diagnostics of thermostat malfunctions
Understanding where the thermostat is located is necessary not only for replacement, but also for initial diagnosis. If the refrigerator Atlant stops turning off or, conversely, does not turn on, the problem often lies in this unit or the contacts suitable for it.
Symptoms of a faulty mechanical thermostat may be the absence of a click when turning the knob, freezing of food to the state of “stone” or, conversely, complete defrosting of the chamber with the compressor running. In electronic models, error codes may appear on the display indicating an open circuit in the sensor.
To check the mechanical thermostat, you can remove it and “ring” it with a multimeter, after first cooling it (for example, putting it in the freezer for 15 minutes) to check the contacts are open. Electronic sensors are checked by measuring their resistance, which must correspond to the temperature curve.
☑️ Diagnostics before replacement
⚠️ Attention: If you find that the capillary tube of the mechanical thermostat is pinched or has traces of oil, replace the entire assembly is mandatory, it cannot be repaired.
Frequently asked questions and answers (FAQ)
Is it possible to replace a mechanical thermostat with an electronic one in an Atlant refrigerator?
No, this is impossible without a deep rework of the entire control system. The mechanical thermostat physically breaks the compressor power circuit, and the electronic unit controls the relay based on sensor signals. Structurally and electrically, these systems are not compatible.
Why does the refrigerator not turn on after replacing the thermostat?
There may be several reasons: incorrect connection of the wires (phase and zero or ground are reversed), the new thermostat itself is faulty (defective), or the problem lies not in the thermostat, but in the starting relay or the compressor itself. Also check whether the bellows tube is tightly pressed to the evaporator.
How can I understand which thermostat is needed for my Atlant model?
You need to look at the markings of the old device. Thermostats have an alphanumeric code (for example, TAM-133, K-59, etc.) that indicates the temperature range and the length of the capillary tube. You need to buy an analogue with identical parameters.
Where is the thermostat located if there is no handle inside the refrigerator compartment?
If there is no handle inside, then you have an electronic model. In this case, the thermostat function is performed by temperature sensors located inside the chambers (usually on the back wall), and the control logic is located in an electronic module, which is most often hidden in the upper part of the refrigerator body or in a niche above the door.
