The situation when food in the refrigerator Atlant freezes where it should simply be cooled, or when a thick ice crust forms on the walls, is familiar to many owners of this equipment. Excessive cold not only spoils supplies, turning vegetables into ice blocks, but also causes the compressor to work harder, which inevitably leads to increased energy consumption. Understanding how to correctly reduce the temperatureis a basic skill for extending the life of the unit.
In most cases, the problem is solved by simply adjusting the mechanical or electronic thermostat, but owners often turn the knob in the wrong direction or do not fully understand the principle of operation systems No Frost. Wrong actions can lead to the fact that the equipment starts working idle or, conversely, stops freezing altogether. In this material we will analyze all the nuances of setting the temperature regime for various models of the Belarusian manufacturer.
It is worth noting that the algorithm of actions may vary significantly depending on the year of manufacture of your device and the type of installed control system. If you have an old mechanics with a “twist” inside the camera, the process will be one, but if you have a modern panel with a display, it will be completely different. It is important to immediately determine the type of your unit so as not to reset the factory settings unnecessarily.
The principle of operation of the thermostat in different models
In order to competently reduce cold, you need to understand which mechanism controls the climate inside your refrigerator Atlant. Older and budget models use a mechanical thermostat, which is a device with a bellows that responds to changes in freon pressure or temperature in the evaporator. Turning the knob changes the compression force of the spring, causing the contacts to open at a higher or lower temperature.
In more modern series, especially two-chamber ones, the control can be electronic. Here temperature mode it is controlled by sensors that transmit data to the control board. The compressor turns on and off (or changes power if there is an inverter) according to a signal from the processor. In such systems, you don’t need to “twist” anything, you just need to set a digital value on the display.
⚠️ Attention: In models with electronic control, after changing the settings, it may take 2 to 4 hours for the temperature background to stabilize. Do not try to change the parameters again during this time.
Systems stand apart No Frost, where the cold is distributed forcibly using a fan. In such refrigerators hypercooling it is often associated not with the operation of the compressor, but with a violation of air circulation or a loosely closed door. The thermostat in them is set to turn off the compressor when a certain temperature is reached in the evaporator, and not in the chamber itself.
Setting the mechanical thermostat
If inside the refrigerator compartment you see a round knob with numbers from 1 to 7 (or from Min to Max), then you are lucky with ease of control. To reduce cold in a refrigerator Atlant with a mechanical regulator, you need to turn the knob towards lower values. Many users make the mistake of believing that number 7 is the “weakest cold,” but the logic here is the opposite: the higher the number, the more freezing the unit is.
The adjustment process is as follows:
- 🌀 Find the thermostat, which is usually located on the right wall or under the lampshade.
- 🔢 Determine the current position of the handle. If it is set to 5-7, the food will freeze.
- 🔄 Smoothly turn the control counterclockwise one notch (for example, from 5 to 4).
- ⏳ Wait a few hours for the temperature to stabilize before making further adjustments.
Do not You should immediately turn the knob to the minimum (1 or Min). A sudden change in operating mode may result in the compressor being unable to reach the required pressure to start the next cycle, or the food in the freezer will begin to defrost. The optimal position for most refrigerators Atlant in summer is considered to be 3, and in winter - 4-5 if the equipment is in an unheated room.
Temperature adjustment in electronic systems
Owners of electronically controlled models, such as the series XM-6221 or XM-4425, are even luckier: there is no need to guess which way to turn. The interface allows you to accurately set the temperature degrees Celsius. Typically, there are touch buttons or a display with indication on the front panel.
To reduce the cold in the main chamber, follow these steps:
- ❄️ Press the "Temperature" button or the snowflake symbol for the refrigerator compartment.
- 📈 Using the “+” or “-” buttons, set the value to +3..+4 °C. This is the standard for storing most products.
- 🔒 If the panel is locked (the lock is on), hold the lock button for 3-5 seconds until it unlocks.
- ✅ Press the confirm button or just wait until the display goes off - the settings will be saved automatically.
By reducing the cold in the upper compartment, you do not affect the freezing in lower However, if you have a single-compressor model, then a decrease in power in the main chamber may indirectly affect the operation of the freezer, since they work in pairs.
☑️ Check before setting up the electronics
Features of the No Frost system and cold distribution
Refrigerators Atlant the system No Frost is more complex, and the concept of “reduce the cold” here may be incorrect. In such units, the temperature in the chamber is equalized due to constant air circulation. If your food freezes at the back wall, this does not always mean that you need to change the thermostat settings.
Often the reason lies in improper loading of the chambers. If you put a pot of soup right next to the hole from which cold air blows, or you packed the shelves too tightly, it breaks down. As a result, the temperature sensor, which may be located in another corner, “thinks” that the refrigerator is warm and does not give the command to turn off the compressor. Locally, at the source of cold, food freezes. circulation of air flows. As a result, the temperature sensor, which may be located in another corner, “thinks” that the refrigerator is warm and does not give the command to turn off the compressor. Locally, near the source of cold, food freezes.
⚠️ Attention: In No Frost systems, the ventilation holes on the back wall cannot be completely blocked by food. This can lead to the formation of ice on the evaporator and failure of the fan.
It is also worth checking the rubber seals. If the door does not fit tightly, warm, moist air constantly enters the chamber. The system No Frost tries to cool and dry it, working in enhanced mode, which leads to freezing of the contents and the formation of ice build-ups inside the case, which are not visible from the outside.
The influence of external factors on the temperature regime
Before grabbing the regulators, analyze the operating conditions. A refrigerator Atlant is a heat pump, and its efficiency directly depends on the ambient temperature. If the equipment is located next to the battery, in direct sunlight or in a niche without ventilation, the compressor will work almost without stopping.
Under such conditions, even a minimal thermostat setting may not save food from freezing, since the unit does not physically have time to turn off. Heat exchange is disrupted and the internal temperature drops below the set temperature due to intense engine operation. Check the gap between the back of the refrigerator and the wall - it should be at least 5-7 cm.
The seasonal factor also plays a role. In winter, when the apartment is cool, the refrigerator can freeze more than in summer. If you have a mechanical regulator, in winter it makes sense to switch it to a “weaker” division, and in summer to a “stronger” one to compensate for the difference in room temperatures.
Why can’t you place the refrigerator near a window?
Direct sunlight heats the case, causing temperature sensors to distort readings. The compressor turns on more often, consuming more energy and creating excess cold inside, while the outside of the housing is heating up.
Diagnostics of faults when it is impossible to reduce the cold
There are situations when you turn the knob to the minimum, set +5°C on the display, but the food still turns into ice. This is a signal that the problem is not in the settings, but in technical malfunction. The most common reason is sticking thermostat contacts. The mechanism “sticks” in the “on” position and does not open the circuit, even when the temperature inside has dropped to -10°C.
Another possible reason is a freon leak or a clogged capillary tube. If there is a shortage of refrigerant or poor circulation, the compressor may run longer in an attempt to build up pressure, but the cooling efficiency drops unevenly. Some areas may experience local hypothermia while others remain warm.
Below is a table for quickly diagnosing symptoms:
| Symptom | Possible cause | Action |
|---|---|---|
| The compressor does not turn off | The thermostat is faulty | Replacing the sensor |
| Ice only at the back wall | Air circulation is impaired | Place food correctly |
| The refrigerator hums, but does not freeze | Freon leak | Call a technician |
| Temperature fluctuates | Electronics problems | Board diagnostics |
⚠️ Attention: If you hear the continuous hum of the compressor for 10-12 hours without breaks, and the food is frozen, immediately unplug the refrigerator to avoid burning out the motor and call a specialist.
Frequent errors during operation
Often users create problems for themselves by handling equipment incorrectly. For example, loading hot products. If you place a hot pan in the chamber, the sensors will detect a sharp rise in temperature and give a command for maximum cooling. While the soup has cooled, neighboring products may have time to freeze. Atlant hot pan, sensors will detect a sharp jump in temperature and give a command for maximum cooling. While the soup has cooled, neighboring foods may have time to freeze.
Another mistake is ignoring defrosting in models with a drip system. If a “coat” of ice more than 5 mm thick grows on the back wall, it acts as a heat insulator. The evaporator cannot effectively release cold, the sensor does not see the required temperature and keeps the compressor on. Regular defrosting (at least once every six months) helps to avoid this.
Use available means for control. Place a separate thermometer in a glass of water on the middle shelf. Check the readings after a day. If the thermometer shows +1°C and the regulator is set to minimum, it means that the equipment requires repair, not adjustment.
FAQ: Frequently asked questions
Why does milk freeze in the Atlant refrigerator, even if the knob is at minimum?
Most likely, the thermostat itself and its contacts have failed “stuck” in a closed state. This could also be a sign of a freon leak, causing the compressor to run non-stop. Diagnostics by a specialist is required.
What position of the thermostat knob is considered normal for Atlanta?
The middle position is considered optimal. If the scale is from 1 to 7, then the norm is position 3 or 4. In winter you can set 4-5, in summer 2-3, depending on the temperature in the room.
Is it possible to reduce the cold in the freezer separately?
In single-compressor models - no, the overall temperature is regulated. In two-compressor models Atlant and models with the Full No Frost system, there are often separate regulators for each compartment.
What to do if, after defrosting, the refrigerator begins to freeze more strongly?
Perhaps there is excess moist air left in the system. Let the refrigerator run idle for 5-6 hours without food. If the situation has not changed, check the tightness of the door and the condition of the seal.
Does the amount of food in the chamber affect the strength of the cold?
Yes, a full refrigerator keeps the cold more stable, but if you jam it full, air circulation will be disrupted. An empty refrigerator will turn on more often. The optimal load is about 50-70% of the volume.
