The situation when food in the refrigerator Atlant begins to become covered with an ice crust, and milk freezes even on the vegetable shelf, is familiar to many owners of this equipment. Instead of cooling, the unit begins to operate in deep freezing mode, which indicates a violation of the temperature regime. Users are often frightened, believing that the device has failed, but in many cases the problem is solved by correct adjustment or simple prevention.
Increasing the temperature inside the chambers is not just a matter of comfort, but also a necessity to preserve the structure of products and save energy. Excessive cooling forces the compressor to wear out, which reduces motor service life. In this article, we will look at mechanical and electronic ways to solve the problem, and also consider cases when a technician’s intervention is required.
Before taking active steps, you need to understand the operating principle of your model. Older two-compartment refrigerators Atlant with one compressor and mechanical controls require physical rotation of the regulator, while modern No Frost systems are controlled by digital commands. Understanding the type of your device is the first step to successful setup.
Features of thermoregulation in Atlant models
Refrigerators of the Belarusian manufacturer Atlant are divided into two main groups according to the type of control: mechanical and electronic. In mechanical models, a device that opens the compressor power circuit when the set temperature is reached is responsible for maintaining cold. The user controls it using a rotary knob located inside the refrigerator compartment or on the body. thermostat - a device that opens the compressor power supply circuit when the set temperature is reached. The user controls it using a rotary knob located inside the refrigerator compartment or on the body.
Electronic models are equipped control unit, which reads temperature sensors and independently regulates the operating time of the compressor and fans. Here the settings are made via the display or LED indicators. It is important to note that in systems No Frost the temperature equalizes faster, but they also have higher requirements for door tightness.
⚠️ Attention: Never try to forcefully turn the mechanical thermostat knob beyond its natural course. This can lead to shaft breakage or displacement of the calibration spring, after which it will be impossible to restore the accuracy of the readings.
Differences in design also affect how exactly the temperature rise occurs. In “mechanics” you directly change the moment of contact opening, but in “electronics” you only set a target value, the execution algorithm of which is embedded in the board’s firmware. Therefore, the methods for solving the problem will be different.
Temperature adjustment in models with mechanical control
If your Atlant is equipped with a rotary knob with divisions from 1 to 7 (or from Min to Max), then increasing the temperature is achieved by decreasing the value on the scale. Paradoxically, the number “7” or “Max” means the lowest possible temperature (extreme cold), and “1” or “Min” means the minimum cooling (warmer). To make the chamber warmer, you need to turn the knob towards lower numbers.
The adjustment process takes time and patience. After turning the thermostat knob, the temperature inside the chamber does not change instantly, but over several hours. Thermal inertia The food and walls of the chamber are large, so you should not turn the regulator every 15 minutes in the hope of a quick result. The optimal step is to change the position by one division and wait 3-4 hours.
In two-chamber models with one compressor, a misalignment often occurs: in the freezer it’s perfect, but in the refrigerator everything is frozen. This is due to the fact that the thermostat sensor usually controls the temperature in the refrigerator compartment, and the freezer is cooled according to the residual principle. If it is too cold in the main chamber, then it will be even colder in the freezer.
☑️ Temperature increase algorithm (Mechanics)
There is a common mistake when users confuse the direction of rotation. On some models Atlant the scale may not be intuitive. If you turn the knob to minimum, but the cold does not go away, perhaps the problem lies not in the settings, but in sticking contacts of the thermostat itself or a freon leak, which is why the compressor works without stopping.
Setting up the electronic control unit
In models with electronics, such as series Atlant XM-4425 or XM-6025, control is carried out through a panel with buttons and a display. Here, temperature increase is an increase in the digital value of the target temperature. For example, if it is set to +2°C, and you need it warmer, you should set the value to +4°C or +5°C.
To enter the setup mode, you usually need to press and hold the button of the corresponding camera (with the image of a snowflake or thermometer) for 3-5 seconds until the numbers start flashing. After this, use the "+" or "-" buttons to set a new value. Do not forget to confirm the selection if the model requires separate confirmation, or simply wait until the flashing stops.
⚠️ Attention: In some models with the system No Frost a sharp increase in temperature (for example, from +3°C immediately to +10°C) may cause a sensor error or activation of the defrost mode. Change the settings smoothly, in steps of 1-2 degrees.
The electronics also allow you to independently adjust the temperature in different chambers if you have a two-compressor model or a Full No Frost system with separate circuits. This gives you flexibility: you can increase the temperature in the refrigerator compartment for storing fruit, while leaving the freezer in deep freeze mode for meat.
Hidden reset
If the electronics behave incorrectly and do not respond to buttons, try performing a hard reset. To do this, unplug the refrigerator for 15-20 minutes. In some models, a reset to factory settings is performed (by long pressing) a combination of buttons, but it is better to check the instructions for the specific model, since the combinations may differ.
The influence of the super freezing mode on the temperature
A frequent cause of extremely low temperatures is the accidentally activated mode super freezing (Super Freeze). On the control panel it is indicated by a lit indicator with a snowflake or the letter "F". In this mode, the compressor operates continuously, ignoring the thermostat readings, which leads to freezing of moisture and deep freezing of food.
To increase the temperature, this mode must be forcibly turned off. In mechanical models, a separate red button next to the thermostat knob is responsible for this. It should be turned off (pressed down or pressed down, depending on the design; usually in working condition it does not light up or protrude). In electronic models, you need to press the corresponding button until the indicator goes off.
After turning off super freezing, the refrigerator will return to normal operation. However, it will not immediately become warmer: the compressor will need time to bring the air to the desired temperature, and the sensors will need to record the change. Typically, the normalization process takes from 2 to 6 hours.
Technical causes of excess cold
If adjusting the settings does not help and the temperature continues to drop, the problem may lie in a technical malfunction. One of the most common reasons is refrigerant leak or clogged capillary tube. If there is a shortage of freon, the compressor tries to compensate for the lack of cold by operating in continuous mode, which ultimately leads to freezing of the evaporator and, as a result, excessive cooling of the products at the beginning of the cycle.
Another reason is a malfunction of the thermostat or temperature sensor. If the thermostat contacts are “stuck” in the closed state or the sensor transmits incorrect data to the control board that the chamber is warm, the compressor will not receive a command to stop. In such cases, replacement of the defective part is required.
It is also worth checking the defrosting system in refrigerators No Frost. If the defrost heating element is burnt out or the timer is jammed, the evaporator becomes covered with a “coat” of ice. The fan begins to drive air through this ice, which has a temperature significantly lower than the set one, which is why a supercooled flow enters the chamber.
A comparative table of settings and problems
For the convenience of diagnosing and adjusting the temperature regime in refrigerators Atlant is given below Pivot table. It will help you quickly determine what action needs to be taken depending on the symptoms and type of control.
| Symptom | Mechanical control | Electronic control | Probable reason |
|---|---|---|---|
| All products are frozen | Turn the knob 1-2 divisions to Min | Increase the value on the display to +4...+5°C | Incorrect thermostat setting |
| The "Snowflake" indicator is on | Press the red button (turn off) | Press the mode button until extinguished | Super freezing mode is activated |
| The refrigerator hums without stops | Check the door fit | Check the closing tightness | Freon leakage or compressor wear |
| Ice only at the rear wall | Defreeze 24 hour | Defrost 24 hours | Drainage clogged or defrosting malfunction |
As can be seen from the table, user actions are often symmetrical for different types of control, but have their own nuances of execution. The main thing is not to ignore technology signals. If, after defrosting and resetting the settings, the problem returns after a few days, this is a sure sign of a technical malfunction.
Prevention and correct placement of products
Sometimes the temperature falls not due to breakdown, but due to violation of operating rules. A clogged refrigerator compartment prevents normal air circulation. Cold air, especially in systems No Frost, should freely wash the products. If the shelves are packed tightly, the temperature sensor may not “feel” the real heat in the center of the chamber and give a command for additional cooling.
Try not to place warm foods directly on the shelf. A sharp jump in temperature forces the compressor to work at its limit, which can disrupt electronic algorithms or lead to freezing of neighboring products. Allow food to cool to room temperature before loading.
Regular defrosting (for drip systems) and cleaning the drainage hole are mandatory procedures. Even a thin layer of ice on the back wall impairs heat transfer and distorts the operation of the thermostat. Keep the seals clean by wiping them with a soft cloth to ensure a tight fit of the door.
Frequently asked questions (FAQ)
Why does everything freeze in the Atlant refrigerator, although the handle is at the minimum?
If the handle of the mechanical The thermostat is turned down to minimum (number 1), but the food still freezes; most likely, the thermostat itself is faulty (the contacts do not open) or there is a misalignment in the cold distribution system. This is also possible if there is a strong freon leak when the compressor works non-stop.
Is it possible to completely turn off the freezer in a two-chamber Atlanta?
In most two-chamber models Atlant with one compressor, it is impossible to completely turn off the freezer separately, since the refrigerant passes through both circuits. You can only increase the temperature in the entire refrigerator. Complete shutdown of the freezer is only possible in models with two compressors through a button on the panel.
How can you tell if the temperature sensor in an electronic refrigerator is broken?
A faulty sensor is often indicated by an error code on the display (for example, F1, F4, etc., the explanation is in the instructions) or chaotic behavior: the refrigerator either freezes too much, then stops cooling completely, or constantly turns on and off at short intervals.
How long should you wait after changing the temperature settings?
It takes from 2 to 6 hours to stabilize the temperature after changing the settings of the thermostat or electronic panel. During this period, it is not recommended to frequently open the doors and load new products in order to allow the equipment to enter a new operating cycle.
