Correct temperature setting is a key factor influencing the safety of products and the durability of the compressor. Owners of Belarusian brand equipment are often faced with the need for precise calibration, especially after defrosting or loading a large volume of warm food. Errors in adjustment can lead to overfreezing of vegetables or, conversely, to spoilage of meat due to insufficient cold.
The company's product range Atlant is varied: from classic two-chamber units with a drip system to modern devices with technology No Frost. The setting principles for them may differ significantly. Understanding the physics of operation of your specific device will help you avoid common mistakes and reduce energy consumption.
In this article we will analyze the mechanics of adjusting thermostats, features of electronic control panels and the nuances of working in different climatic conditions. You will learn to determine the optimal values for the summer and winter periods, and also understand when a specialist’s intervention is necessary.
Principles of operation of the thermostat and mechanical adjustment
In classic models of refrigerators Atlant, such as the MXM-1700 or MXM-2800 series, control is carried out mechanically thermostat. This device is a relay that opens the electrical circuit when the set temperature inside the chamber is reached. The adjustment is made by turning the handle, usually located inside the refrigerator compartment or on the top panel of the case.
The thermostat scale is most often graduated from 0 to 7 (or from Min to Max). It is important to understand that the numbers do not represent degrees Celsius. They indicate the intensity of the compressor. The higher the value, the lower temperature inside the chamber. Setting the knob to the “7” or “Max” position causes the compressor to work almost without stopping, which can lead to icing of the evaporator.
⚠️ Attention: Constant operation of the compressor at maximum power (position 7) significantly reduces the life of the motor and increases energy consumption. Use this mode only for quick freezing.
For everyday use, it is recommended to set the regulator to the middle position - usually these are numbers 3 or 4. This provides a balance between cooling and resting the compressor. If you notice that the food in the back of the refrigerator compartment is starting to freeze, you should reduce the value on the thermostat.
Setting up electronic panels and displays
Modern models, for example, series XM-6221 or XM-4625, are equipped with electronic control. Here, the settings take place through the keypad and digital display located on the door. This allows you to set the temperature with an accuracy of a degree, which cannot be done mechanically.
The setting process usually looks like this: you need to press the button Temperature or Mode, after which the current temperature indicator will start flashing. Using the arrow buttons + and - you select the desired value. After the blinking stops, the new parameter is stored in the controller’s memory.
Electronics allows you to independently regulate the climate in the refrigerator and freezer compartments. For the refrigerator compartment, the range from +3°C to +5°Cis considered optimal, and for the freezer - -18°C. Some models have preset modes, such as "Holiday" or "Super Cooling", which are activated by separate buttons.
What is the "Holiday" mode?
In this mode, the temperature in the refrigerator compartment rises to +10...+15°C to prevent mold and odor in the absence of owners for a long time, and the freezer continues to operate as normal.
Optimal temperature conditions for different products
Not all products require the same storage conditions. Incorrect placement can lead to the fact that even with the overall temperature set correctly, some of the stock will spoil. The freshness zone, if provided for by the design, should have its own parameters that are different from the main shelf.
Meat and fish products are best stored at a temperature of about 0...+2°C. Dairy products feel comfortable when +4°C. Vegetables and fruits, especially sensitive to cold, should not be exposed to temperatures below +5°C, otherwise they will lose their taste and structure.
- 🥩 Meat and fish: require the coldest mode, it is better to place them closer to the back wall or in the zone of zero freshness.
- 🥛 Dairy products: the middle position is optimal, you should not put milk on the coldest shelf at the back wall.
- 🥬 Vegetables and herbs: store in the lower drawers, where the temperature is higher and more stable, to avoid freezing of moisture in the cells.
Compliance with these rules will extend the shelf life of products without extreme lowering of temperature throughout the entire volume of the chamber, which saves equipment resource.
Seasonal adjustment: Summer and Winter
The ambient temperature directly affects the operation of refrigeration equipment. In summer, when the room is hot, heat exchange is disrupted and the compressor takes longer to cool the chambers. In winter, the situation is the opposite, but there are nuances here, especially for equipment installed on unheated balconies.
In summer, the thermostat should be switched to “colder” values (numbers 4-5 or setting +3°C). This compensates for the heating of the case from the warm air in the room. However, you should not set the maximum mode if the room is cool - this will lead to the formation of a “snow coat.”
⚠️ Attention: If the refrigerator is installed in a room where the temperature drops below +10°C (for example, in a country house in winter), the compressor may not turn on at all. In such cases, a special low-temperature kit (heating element) is required, since the standard thermostat will not turn on.
In winter, when heating is operating, the air in the kitchen is dry and warm. Check to see if the condenser (grid at the back) is overheating. If the radiator is hot, provide better air flow by moving the appliance away from the wall. In winter, you can slightly reduce the cooling intensity if the room is cool.
Super freezing and fast cooling modes
The function Super Freeze (super freezing) is designed for quick freezing of large quantities of fresh food. When this mode is activated, the compressor runs continuously, ignoring the thermostat readings. This allows you to quickly lower the temperature in the freezer to -24°C or lower.
This mode should be used with caution. In mechanical models, a separate button or the extreme right position of the regulator with a red dot is often responsible for turning on super freezing. A lit red light indicates operation in enhanced mode.
It is critically important not to leave the refrigerator in this mode for longer than 24-48 hours. Long-term operation without stopping will lead to overheating of the compressor windings and failure. After freezing the products, you must manually return the regulator to the normal position.

Diagnosis of problems: when the settings do not help
There are situations when changing the position of the regulator does not produce results: temperature does not fall or, on the contrary, everything freezes even at a minimum. This may indicate a malfunction. Most often the problem lies in a refrigerant leak or a stuck thermostat.
If the compressor hums, but there is no cold, or if it turns on only for a few seconds and clicks, these are signs of a serious breakdown. It is also worth paying attention to the sealing rubber bands: if they do not fit tightly, warm air enters inside, and the equipment cannot cope with the load.
| Symptom | Possible cause | Action |
|---|---|---|
| Temperature does not goes down | Freon leak or compressor breakdown | Call a technician |
| Food freezes at a minimum | Thermostat is faulty (contacts are stuck) | Replacing the thermostat |
| Ice only at the back wall | Normal for a drip system | Carry out defrosting |
| The compressor does not turn off | Lack of refrigerant or wear | System diagnostics |
Independent replacement of the thermostat is only possible if you have the skills to work with electricians and tools. In models with electronics, diagnostics are more complicated and often require a special tester.
Frequently asked questions (FAQ)
Why does ice freeze in the Atlant refrigerator, even if the temperature is set to average?
This can happen for several reasons: a door that is not tightly closed, loading hot products, a leak in the seal, or a malfunction of the defrost system (heating element or timer). In models with a drip system, a small layer of ice on the back wall during compressor operation is the norm.
What temperature should be set in the Atlant freezer in the summer?
The optimal value for the freezer all year round remains -18°C. If you have a mechanical control, leave the regulator in position 3 or 4. In the summer, just make sure that the refrigerator is not standing in the sun and the radiator at the back is well ventilated with air.
What does the blinking Alarm indicator on the display mean?
The alarm indicator signals that the temperature in the chamber has risen above the permissible limit. This often happens immediately after turning on the refrigerator or after loading a large amount of warm food. If the indicator does not go out after a few hours, check that the door is closed tightly.
Is it possible to transport the Atlant refrigerator at temperatures below zero?
You can transport it, but you cannot immediately plug it into the network. The oil in the compressor thickens in the cold. After being brought into a warm room, the equipment must stand turned off for at least 4-6 hours (preferably a day) so that the oil warms up and the glass into the crankcase, otherwise the compressor will burn out.
