Correct setting of the temperature regime is the key to long-term preservation of food and health your family. In two-chamber models of the Belarusian brand Atlant the cold distribution system may differ depending on the year of manufacture and the type of compressor. Many owners are often faced with a situation where it is too warm in the refrigerator compartment, and, on the contrary, in the freezer compartment, food freezes or becomes covered with an ice crust.
Understanding the physical principles of operation of the device allows you to avoid common mistakes. Normal temperature in the refrigerator compartment should be in the range from +2 to +5 degrees Celsius. It is under these conditions that pathogenic bacteria multiply the slowest, and the freshness of vegetables and meat is preserved for the longest possible time. If the indicators go beyond these limits, the shelf life of the products is sharply reduced.
More stringent standards are relevant for the freezer. Here the air should cool to -18 degrees and below. This mode ensures deep freezing, preserving the fiber structure of meat and fish, as well as the vitamin composition of berries. Modern models Atlant equipped with electronic or mechanical regulators that allow the user to independently adjust the operation of the compressor depending on the load of the chambers and the ambient temperature.
Standard temperature conditions according to GOST and manufacturer's recommendations
According to technical data sheets and international standards, each compartment of the refrigeration unit has its own target indicators. In the refrigerator compartment, which is intended for storing ready-made food, dairy products and vegetables, optimal value considered to be +4°C. A short-term fluctuation within one degree in any direction is allowed, but the stability of the regime here is more important than the absolute minimum.
The freezer, or freezer, should maintain a temperature no higher than -18°C. This value is the standard for long-term storage (up to 12 months). If you plan to freeze large volumes of fresh food, the Super Freeze function allows you to temporarily lower the temperature to -24°C to quickly pass the critical point of crystallization of water in the product cells.
It is important to consider that the cold distribution inside the chambers is uneven. Cold air is heavier than warm air, so it sinks. The shelves near the back wall, especially near the evaporator, are always colder than those near the door. Therefore, the placement of products should be logical: perishable items are closer to the source of cold, and drinks and sauces are on the door.
How to set the thermostat depending on the model
Setting the climate inside the refrigerator depends on the type of control installed by the manufacturer. Older and budget models Atlant use a mechanical thermostat. It is a rotary knob with divisions from 1 to 7 (or from Min to Max). It is important to remember here: the number does not indicate degrees, but the work intensity compressor. The higher the number, the colder it will be inside.
For mechanical regulators, the "golden mean" is the position of the knob on division 3 or 4. Setting the value to maximum (6 or 7) forces the compressor to work almost without interruption, which can lead to freezing of the evaporator and increased energy consumption. The minimum value (1) may not be enough for high-quality cooling in hot weather.
In models with electronic control, the setting is made through a panel on the door or inside the chamber. Here you see the exact numerical values. Adjustment is carried out using the "+" and "-" buttons. The electronics itself controls the on and off cycles, maintaining the set parameter with high accuracy. This eliminates the need for the user to guess what temperature is actually set.
If you change the settings, don't expect instant results. The compressor takes time (4 to 8 hours) to stabilize the climate in all corners of the chamber. After changing the position of the regulator, allow the equipment to sit before a new check.

The influence of the type of defrosting on the distribution of cold
Two-chamber refrigerators Atlant may have different defrosting systems: drip (Static) or No Frost. This is a critical parameter that affects exactly how cold air will be distributed. In models with drip system moisture settles on the back wall, freezes and periodically thaws, flowing into the drain. In such chambers, the temperature difference between the back wall and the door can reach 3-4 degrees.
System No Frost (or Low Frost in some modifications) ensures air circulation throughout the entire volume. The fan forces air through the evaporator, cooling all shelves evenly. Here the temperature difference is minimal, which allows you to place food in any corner of the chamber. However, such a system dries out food that is not packaged in containers more strongly.
⚠️ Attention: In refrigerators with a drip defrosting system, never press food close to the back wall. This can lead to their freezing and damage to the thin plastic or enamel of the evaporator.
In No Frost freezers, air also circulates forcibly. This prevents the formation of an ice coat, but requires the doors to be tightly closed. If the door is not closed tightly, warm, moist air will constantly enter the chamber, which will lead to the formation of snow slush on the products and increased energy consumption.
Why does meat dry in No Frost?
The No Frost system constantly blows dry cold air. If meat is not packaged in a sealed bag or container, surface moisture will evaporate faster than under normal conditions. This is called "freezer burn". The product becomes safe, but loses taste and texture.
Table of temperature zones inside the chamber
Understanding exactly where in the refrigerator it is colder and where it is warmer will help you use the space rationally. Not all shelves are equal in their thermal insulation properties. Below is a table showing the approximate temperature distribution in a standard chamber when setting the thermostat to +4°C.
| Location area | Approximate temperature | What to store |
|---|---|---|
| Top shelf | +5...+6°C | Ready food, drinks, cakes |
| Middle shelf | +3...+4°C | Dairy products, sausages, cheese |
| Lower shelf (above drawers) | +2...+3°C | Raw meat, fish, semi-finished products |
| Door shelves | +6...+8°C | Sauces, oil, medicines, juices |
| Vegetable boxes | +4...+5°C | Vegetables, fruits, herbs |
Using this scheme, you can extend the life of products. For example, raw meat, which is an ideal environment for bacteria, is best placed on the coldest bottom shelf. But ketchup or a bottle of water can be kept on the door, where the temperature is higher.
Factors influencing temperature changes
Even with the correct setting of the thermostat, the actual temperature inside the chambers may fluctuate. This is influenced by many external and internal factors. One of the main ones is chamber loading. An empty refrigerator takes longer to cool down and operates less stably, since foods (especially those containing water) tend to accumulate cold. A full refrigerator keeps the temperature better.
The frequency of door openings also plays a role. Each opening lets warm air from the kitchen into the chamber. If you cook and look inside often, the compressor is forced to turn on more often. In the summer, when the ambient temperature in the kitchen is high, it is recommended to increase the load on the cooling system by turning the control knob towards higher values.
- 🌡️ Room temperature: if the kitchen is hotter than +30°C, the refrigerator may not be able to cope with the load even at maximum.
- 🍲 Food temperature: loading hot or warm food sharply increases the average temperature inside.
- ❄️ Condition of the seal: worn rubber allows heat to pass through, causing the equipment to run idle.
⚠️ Attention: Never put hot pots in the refrigerator. This will not only spoil other products, but can also lead to compressor failure due to excessive load.
Common problems with temperature conditions
If you set the regulator correctly, but the temperature is not normal, there may be a technical malfunction. Users often complain that in the refrigerator compartment too warm, although the compressor is working. This may indicate a refrigerant (freon) leak. In this case, the gas evaporates and the cooling capacity drops.
The other extreme is that the freezer is covered with a thick layer of ice, but in the refrigerator compartment, on the contrary, everything freezes. This is a sign of a faulty thermostat or temperature sensor. The mechanical thermostat may “stick” in the “On” position, preventing the compressor from resting. The electronic sensor may transmit incorrect data to the control board.
It is also worth checking the condensate drainage system. If the drainage hole is clogged with crumbs or ice, the water does not drain, freezes on the walls and blocks the air circulation channels. In No Frost models, this causes the fan to stop effectively cooling the chamber.
To diagnose problems, you can use the visual inspection method. If a “fur coat” forms unevenly on the back wall of the refrigerator compartment (for example, only on one side or in the form of icicles), this is a sure sign of a malfunction of the defrosting system or a lack of freon.
Why does ice freeze on the back wall in the Atlant refrigerator?
The formation of ice on the back wall in models with a drip system is a normal operating process. Moisture from the air condenses on a cold surface and freezes. Periodically, the compressor turns off, the wall heats up, and the ice melts, flowing into the drain. This becomes a problem if the layer of ice turns into a thick “fur coat” that does not melt. This indicates a loose door fit or a malfunction of the defrost sensor.
Is it possible to store medicines in the Atlant refrigerator?
You can store medicines, but with caution. The standard temperature of +4°C is suitable for many drugs, but not for all. Some insulins or vaccines require strictly +2...+3°C, while others cannot be frozen even for a short time. Due to temperature differences at the back wall and at the door, it is better to use a separate thermometer and place medications away from the evaporator. Always read the instructions for the product.
How often do you need to defrost the Atlant refrigerator?
Models with the No Frost system do not require manual defrosting; it is enough to wash them 1-2 times a year. Refrigerators with a drip system (Static) also do not need frequent defrosting, since defrosting occurs automatically. However, manufacturers recommend complete defrosting and washing at least once every 6-12 months for hygiene and odor removal. If the layer of ice in the freezer exceeds 5-7 mm, defrosting is required.
