How to correctly change the temperature in the Atlant refrigerator

Temperature adjustment is a basic skill necessary for every owner of household appliances who wants to ensure long-term storage of products and energy efficiency of the unit. In Belarusian brand refrigerators Atlant this process can vary significantly depending on the type of control: mechanical or electronic. Understanding the principles of operation of the thermostat allows you not only to set the optimal cold, but also to extend the life of the compressor, avoiding its overload.

Incorrectly set parameters often cause rapid spoilage of food, the formation of excessive ice, or, conversely, insufficient cooling. In this article we will analyze in detail how change settings for various series of equipment, consider the nuances of the system No Frost and give recommendations for seasonal adjustment of the operating mode.

Features of temperature control in different models

All refrigeration units Atlant are divided into two large groups according to the type of climate control inside the chambers. Older or budget models use a mechanical thermostat, which is a round disk with divisions. In modern series, especially with the system No Frost, electronic control panels with digital displays are installed, where the temperature can be set with an accuracy of a degree.

Mechanical control relies on the physical expansion of gases or liquids in the capillary tube of the sensor. When you turn the knob, you change the pressure at which the contacts close, starting the compressor. The electronics work based on the readings of thermistors (thermistors), which transmit data to the control board. This allows you to implement functions such as super freeze or open door indication.

⚠️ Attention: If the red alarm indicator is on the display, this does not always mean a breakdown. Often this is a signal that the temperature inside the chamber has risen above the permissible norm, for example, after defrosting or loading a large amount of warm food.

It is important to understand that in two-chamber refrigerators with one compressor (classic design), the temperature in the freezing and refrigerating chambers is controlled indirectly. The main emphasis is on cooling the freezer, and in the refrigerator compartment the cold is distributed according to the residual principle or through a special channel.

Adjusting the mechanical thermostat

In models with mechanical control, the regulator is usually located inside the refrigerator compartment on the top wall or on the side. It is a round knob with numbers from 0 to 7 (or Min to Max). Many users mistakenly believe that the numbers indicate degrees Celsius, but these are just conventional units of cooling power.

The principle of operation is simple: the higher the number, the lower temperature inside the chamber. Position “0” means the compressor is completely turned off, and position “7” (or Max) forces the unit to work continuously, which can lead to freezing of the evaporator and excessive consumption of electricity. The optimal handle position for year-round use is between 3 and 4.

If you notice that the food in the refrigerator compartment begins to freeze at the back wall, you need to turn the knob towards lower values. Conversely, if the milk turns sour quickly and the ice cream melts in the freezer, you should increase the cooling power. Do not make sharp turns of the regulator; it is better to change the setting by one division and wait a few hours for the mode to stabilize.

Setting up electronic control and display

Refrigerators Atlant electronically controlled units, such as the XM-4425 or XM-6025 series, allow the user to set precise temperature settings. The control panel can be located on the outside door or inside the chamber. To change parameters, a touch panel or physical buttons combined with a display are usually used.

To change the temperature, you often need to press and hold the button with the image of a thermometer or snowflake for 3-5 seconds until the flashing indicators appear. After activating the setting mode, you can change the values ​​with short presses. In two-compressor models, you can independently regulate the climate in the refrigerator and freezer compartments.

Sequence of actions to reset the settings:
1. Press the "Menu" or "Select" button.
2. Hold for 5 seconds until a beep sounds.
3. Select the camera using the "+" or "-" buttons.
4. Click "OK" to save.

The electronics also allow you to activate the Super Freeze (super freeze) mode, which forcibly turns on the compressor for a long time to quickly freeze fresh food. Do not forget to turn off this mode manually after 24 hours if the model does not support automatic return to previous settings, since constant operation at maximum harms the life of the motor.

⚠️ Attention: In some electronically controlled models, changing settings is blocked if the refrigerator door is open. Close the chamber tightly and wait 1-2 minutes before attempting adjustment.

Specifics of two-compressor refrigerators

Two-compressor models Atlant are more energy efficient and quieter, as they have two independent cooling circuits. This means that you can completely turn off one of the chambers (for example, the freezer if you're going on vacation) while the other continues to work normally. Temperature control in such systems is completely autonomous.

For the refrigerator compartment in such models, the optimal temperature is considered to be from +3°C to +5°C. It is recommended to maintain the temperature in the freezer at -18°C. If you store large stocks of meat or berries for long-term storage, you can lower the temperature to -20°C or -24°C, but this will increase energy consumption.

The independence of the circuits also means that a malfunction or adjustment of one thermostat does not in any way affect the operation of the second. This simplifies diagnostics: if one chamber is warm and the other is cold, the problem is most likely local (sensor, fan, freon leak in a specific circuit).

Seasonal adjustment and wintering mode

Many users wonder whether it is necessary to change the refrigerator settings in winter and summer. This is really important for mechanical thermostats. In the summer, when the ambient temperature in the kitchen is high, it is more difficult for the compressor to transfer heat through the condenser. In this case, it is better to move the regulator knob closer to the average values ​​to avoid continuous operation of the motor.

In winter, if the refrigerator is in an unheated room (for example, in a country house or in a garage), the situation is the opposite. The oils in the compressor thicken, and the temperature difference between inside and outside is minimal. Some older models Atlant may stop turning on because the thermostat “thinks” that it’s already cold.

Is it possible to store a refrigerator on the balcony in winter?

Manufacturers do not recommend storing a switched-on refrigerator on the balcony at temperatures below +5°C. This can lead to oil thickening, tube damage and compressor failure. If there is no other way out, use a special thermal cap.

Modern models are often equipped with a climate class SN-T, which means the ability to work in a wide range of ambient temperatures (from +10°C to +43°C). If your refrigerator belongs to class N (normal), then operating it at temperatures below +10°C may be incorrect without additional measures.

If you brought the refrigerator from the cold, let it stand turned off for at least 4-6 hours before turning it on, so that the condensation evaporates and the oil warms up.

Typical problems and their solution

Sometimes users are faced with a situation where changing the position of the regulator does not produce a visible result. The refrigerator compartment is still warm, or, conversely, everything is freezing. In mechanical models, a common cause is sticking of the thermostat contacts or loss of sensitivity of the bellows.

In models No Frost the problem may lie in a malfunction of the defrost sensor or fan. If the fan does not circulate air, cold does not enter the chamber, although the evaporator may be frozen. In this case, the electronics may show an error or simply display the temperature incorrectly.

• 🔍 Check the seals: If the door does not fit tightly, the cold escapes and the compressor works non-stop, trying to compensate for the losses.
• ❄️ Icing: A thick layer of ice on the back wall of a mechanical refrigerator indicates that the thermostat is not working turns off the compressor in time.
• 🔊 Noisy operation: The humming noise may get worse when running at maximum speed (high temperature settings).

If you have tried all the settings, but the refrigerator does not keep cold, there may be a leak. refrigerant. In this case, adjusting the thermostat is pointless - you need to call a technician to top up with freon and find the leak.

⚠️ Attention: Replacing the thermostat or sensors yourself requires skills in working with electrical equipment and, in some cases, with the refrigeration circuit. Careless handling may result in electric shock or damage to the system.

Frequently asked questions (FAQ)

Why in the refrigerator Ice freezes in Atlant, even if the minimum temperature is set?

Ice formation at minimum settings (number 1-2) may indicate a malfunction of the thermostat, which does not open the circuit, or problems with the door seal, through which moist air penetrates. Also, the cause may be a clogged drainage hole.

What temperature should be set in the Atlant freezer for long-term storage?

For long-term storage of food (up to 1 year), the optimal temperature is -18°C or lower. At a temperature of -6°C (one asterisk), products are stored for only a week, at -12°C - for about a month.

What does the flashing temperature indicator on the display mean?

A flashing indicator usually indicates that the current temperature in the chamber is higher than the set norm. This often happens immediately after turning on, defrosting, or loading a large amount of food. If the blinking does not stop after a day, check the tightness of the door.

Is it possible to turn off the freezer in a two-compressor Atlanta?

Yes, in two-compressor models you can control each chamber independently. To turn off the freezer, you usually need to press the corresponding button and hold it, or move the regulator to the “0” or “Off” position if it is a mechanical model.
