The situation when food is in the refrigerator compartment are covered with an ice crust, and the milk freezes at the back wall, familiar to many owners of equipment from the Belarusian brand. Often users are looking for a solution, wondering how to turn down the cold in the Atlant refrigerator without calling a technician. This is a common problem that can be caused by both incorrect settings of the regulators and technical features of the compressor operating in hot weather or at full load.
Understanding the operating principles of your model is the first step to solving the problem. In most cases, it is enough to properly calibrate the thermostat or check the tightness of the seals to return to normal temperature conditions. However, it is important to act consistently so as not to upset the balance of the entire unit. cooling systems your model is the first step to solving the problem.

However, it is important to act consistently so as not to upset the balance of the entire unit.
In this material we will analyze all possible adjustment methods, from simple turns of the knob to complex settings of the electronic control unit. You will learn why Atlant refrigerator can work in enhanced mode and how to fix it yourself, maintaining food freshness and the serviceability of equipment.
Principles of operation of the thermostat in different models
The main element responsible for maintaining the microclimate inside cameras is thermostat. Depending on the series and year of manufacture, the Atlant refrigerator can be equipped with a mechanical handle or a modern electronic control panel. Mechanical models, such as the popular series KSh-280 or MHM-1700, use a rotary switch with a scale from 1 to 7 (or from Min to Max).
The logic of the mechanical regulator often causes confusion among users. The numbers on the scale do not indicate degrees Celsius, but the work intensity compressor. The higher the number you set, the longer the engine runs and the colder it gets inside. Therefore, to reduce the cold, you need to turn the knob towards a lower value.
- 🌡️ Position “1” or “Min” - minimum cold production, the compressor operates in short cycles.
- ❄️ Position “3” or “4” - standard mode recommended by the manufacturer for long-term operation.
- 🧊 Position “7” or “Max” - maximum cooling, used for quick freezing or in very hot rooms.
Electronic models, for example, series Atlant XM-4425 or 4025, allow you to set the exact temperature in degrees Celsius via display. Everything here is intuitive: to reduce the cold, you need to increase the target temperature value. However, even in such systems there are nuances associated with the super coolingmode, which we will discuss below.
⚠️ Attention: A sharp change in the position of the thermostat (for example, from 7 immediately to 2) may result in the compressor not starting immediately due to restart protection. Wait 10-15 minutes after adjustment before assessing the result.
It is important to understand that a mechanical thermostat is a device that responds to the temperature of the evaporator, not the air in the chamber. Therefore, changes in the settings do not appear instantly, but within several hours of operation of the unit.
Algorithm for manual adjustment of a mechanical regulator
If you determine that your refrigerator is working too intensely, you need to adjust the settings. This process requires patience and care as the temperature inside the chamber changes slowly. Start by assessing the current position of the knob.
To begin, turn the knob one notch downwards (for example, from 5 to 4). You should not try to immediately set the minimum value, as this can lead to food spoilage, especially if a lot of meat or dairy products are stored in the refrigerator. After adjustment, you need to give the equipment time to stabilize.
☑️ Setting up a mechanical thermostat
The next stage is monitoring the result. Use a household thermometer placed in a glass of water placed on the middle shelf. This will give the most accurate idea of the actual storage temperature, in contrast to the readings of the built-in sensors, which may have an error.
If, after 6-8 hours of operation in the new mode, the products are still freezing, repeat the procedure, reducing the power by another notch. The optimal mode is considered to be one in which the temperature in the main chamber is kept in the range of +2...+4°C, and condensation or frost does not form on the shelves.
In some cases, especially in older models, the regulator knob may “loose” or scroll without changing the internal resistance. In such a situation, the visual position of the number may not correspond to the actual operating mode. Only experimental selection or replacement of the thermostat itself will help here. Place a regular jar of water in the refrigerator and lower the thermometer into it. This is the most reliable way to find out the real temperature, since sensors on the walls can lie due to ice. thermostat.
Temperature control in models with electronics
Owners of modern Atlant refrigerators with a system No Frost and electronic control have greater opportunities for fine-tuning. The control panel is usually located on the outside of the door or inside the refrigerator compartment. Here you can independently adjust the temperature in the freezer and refrigerator compartments.
To reduce the cold in the refrigerator compartment, find the button responsible for this compartment (often indicated by a snowflake symbol or the inscription “HK”). By clicking on it, you cyclically change the temperature value. You need to increase the digital value. For example, if the setting is +2°C, change it to +4°C or +5°C.
Particular attention should be paid to the Super Cool function. This mode forces the compressor to run non-stop, quickly reducing the temperature. Often, users accidentally activate it, and then cannot understand why the food is covered with ice.
- 🔍 Look for an indicator on the panel that says “Super” or a picture of several snowflakes.
- 🔘 Press the corresponding button to deactivate the mode (the indicator should go out).
- ⏳ After turning off the mode, the refrigerator will return to the standard operating algorithm after a few hours.
Also in electronic models it is worth checking the freezer setting. If the temperature is extremely low (eg -24°C), the overall heat transfer may affect the adjacent walls of the refrigerator compartment, especially in single compressor models. It is optimal to keep the freezer at -18°C.
⚠️ Attention: In models with a display, locking the buttons (“Child Lock”) may prevent you from changing settings. If pressing does not respond, check if the lock indicator is on and unlock the panel according to the instructions (usually with a long press).
Why are the settings reset?
If the Atlant refrigerator periodically resets the temperature settings to factory settings, this may indicate power surges or a faulty control board. In this case, it is recommended to use a surge protector.
The influence of defrosting and load modes
Sometimes the problem of excess cold lies not in the settings, but in a violation of operating rules. The Atlant refrigerator, like any other appliance, is sensitive to how it is filled with food. An empty refrigerator and an overloaded one work differently.
If the chambers are filled to capacity with products, it is broken air circulation. Cold air cannot be distributed evenly, creating local areas of extremely cold temperatures while other places are warm. Products near the back wall may freeze, even if the thermostat is set to minimum.
On the other hand, working in defrost mode also affects the situation. In refrigerators with drip system (crying wall), ice periodically forms on the back wall, which then melts. If you set the temperature too low, the ice does not have time to completely melt, forming a “fur coat”. This isolates the temperature sensor, and the refrigerator continues to freeze, believing that there is still plenty of heat.
It is important to follow the following loading rules:
- 📦 Do not place food close to the back wall, leave a gap of 2-3 cm for circulation.
- 🥩 Hot dishes must be cooled to room temperature before placing in the chamber.
- 🌬️ Make sure that the ventilation holes (in No Frost) are not blocked by bags or boxes.
Regular defrosting (for drip systems) at least once every 6 months helps remove excess ice crust and restore normal heat exchange. This is a simple procedure that often solves the problem of “freezing” without interfering with the settings.
Technical reasons for excess cold
If adjusting the thermostat does not help, and the Atlant refrigerator continues to work at its limit, producing sub-zero temperatures in the refrigerator compartment, there may be a technical malfunction. There are several typical problems that simulate the “maximum” setting.
One of the common causes is a freon leak or a clogged capillary tube. Paradoxically, if there is a shortage of refrigerant, the compressor can work almost non-stop, trying to reach the set temperature. As a result, the evaporator in the freezer is only partially covered with ice, and in the refrigerator compartment there may be either a lack of cold or, conversely, local freezing near the supply channel. Another common problem is a malfunction of the temperature sensor itself. If the contacts inside the thermostat are “stuck” in the closed position, it does not give a command to turn off the compressor, even when there is already a deep minus inside. In electronic models, the sensor transmitting incorrect data to the control board could fail.

In electronic models, the sensor could fail, transmitting incorrect data to the control board.
It is also worth paying attention on door seals. If they are dry, dirty or do not fit well, warm, moist air constantly enters the chamber. Sensors detect the temperature increase and instruct the compressor to work harder. As a result, you get both water leaks and frozen food.
Comparative table of modes and temperatures
For ease of setup, we provide a table of correspondence between the regulator positions and approximate temperature values. Remember that these values may vary depending on the model Atlant and room temperature.
| Knob position | Operating mode | Approximate t° in HK | Recommendation |
|---|---|---|---|
| 1 (Min) | Economical | +6...+8°C | Summer or light load |
| 2-3 | Standard | +3...+5°C | Daily use |
| 4-5 | Reinforced | +1...+3°C | Large load of products |
| 6-7 (Max) | Frozen | 0...+2°C | Only for quick freezing |
Using this table as a guide, you can quickly select the optimal mode for your conditions. If you set the regulator to “2”, and the temperature is still about 0°C, then the problem is not in the settings, but in the serviceability of the components.
Frequently asked questions (FAQ)
Why does the water freeze in the Atlant refrigerator on the shelf next to the back wall?
This is typical for a drip system. The back wall is the evaporator, and its temperature is always lower than in the center of the chamber. If food touches or is pressed against the wall, it freezes. This may also indicate that the thermostat setting is too low (above 4-5).
Is it possible to turn down the cold if the thermostat knob is broken?
You can temporarily try to carefully turn the regulator rod with pliers, but this is risky. It is better to replace the knob or the entire thermostat. Using an electronic socket timer is a temporary solution, but it does not guarantee a stable food temperature.
Does the temperature in the room affect the operation of the refrigerator?
Yes, significantly. If the kitchen is hot (+30°C or higher), the compressor has to work longer to remove the heat. In such conditions, even at medium settings, the refrigerator can work to the limit. It is recommended not to place equipment near the stove or in direct sunlight.
