Correctly setting the temperature in a two-chamber refrigerator Atlant is the key to long-term preservation of food and energy savings. Many users encounter difficulties when starting up for the first time or after defrosting, not fully understanding how a mechanical thermostat works. Unlike modern electronic systems with a digital display, classic models require manual selection of the optimal position of the control knob.
Errors in setting can lead to rapid deterioration of frozen stocks or, conversely, to the formation of a thick ice crust on the walls of the chamber. Temperature in the freezer directly affects the operation of the compressor: if the mode is selected too “cold”, the equipment will work for wear without interruption. In this article we will analyze all the nuances of adjustment, decipher the scale values and answer frequent questions from owners of Belarusian equipment.
The principle of operation of the thermostat in Atlant refrigerators
In most two-chamber models of the brand, especially in the MXM and KXM, used mechanical thermostat. It is a device that responds to changes in temperature in the evaporator or directly in the chamber. Adjustment is made by turning a knob, usually located inside the refrigerator compartment or on the top of the cabinet. The mechanism does not show degrees Celsius, but operates in conventional units from 1 to 7 (or from Min to Max).
It is important to understand the physics of the process: the higher the number on the scale, the lower temperature there are chambers inside. This often causes confusion. Position “1” or “Min” means that the compressor will turn on rarely and work for a short time, maintaining a relatively warm mode. The “7” or “Max” position forces the unit to work almost continuously, trying to achieve the maximum possible cold.
The thermostat is connected to a bellows tube, which transmits data on the thermal expansion of the refrigerant. Temperature Settings is actually a calibration of the switch-on and switch-off point of the motor. If you set the knob to maximum, you reduce the difference between the on and off temperatures, causing the appliance to freeze more intensely. However, it is worth remembering that mechanical regulators have an error, and the actual temperature may differ from the expected one depending on the load of products.
⚠️ Attention: A sharp turn of the regulator knob from extreme minimum to maximum (or vice versa) can lead to false operation of the protection or a long compressor operation cycle. Change the settings smoothly, giving the system 30-40 minutes to stabilize.
Why are there no exact degrees on the handle?
Mechanical thermostats are calibrated at the factory for the average climate zone. The scale from 1 to 7 is not degrees, but relative cooling power. The exact value in degrees Celsius depends on many factors: how full the chambers are, the temperature in the room and the condition of the seals. Therefore, the manufacturer does not apply a degree grid so as not to mislead the user.
Deciphering the thermostat scale and optimal values
The regulator scale in refrigerators Atlant is usually graduated with numbers from 1 to 7, where 1 is the minimum cooling, and 7 is the maximum. There is also an option with the inscriptions “Min” and “Max”. For normal operation of a two-chamber refrigerator under standard conditions (room temperature +18...+25°C), it is recommended to set the handle to the middle position.
Position 3 or 4is considered the optimal value for everyday use. In this mode, the freezer can maintain a temperature of about -18°C, which meets international standards for frozen food storage. The refrigerator compartment keeps about +4...+5°C. This is the “golden mean” that provides a balance between food safety and energy consumption.
If you have loaded the freezer with a large amount of fresh food that requires quick freezing, you can temporarily move the regulator to position 5 or 6. However, it is not recommended to keep the equipment in this mode all the time. This leads to accelerated wear of the compressor and the formation of excess ice on the evaporator, which in models with manual defrosting will require more frequent maintenance.
Step-by-step instructions: how to set temperature
The setting process is simple, but requires following a sequence of actions to achieve an accurate result. First you need to open the refrigerator door. Find the thermostat knob; in different models it can be located inside at the top right, on the ceiling of the camera or on the outer end of the case.
Turn the knob to set the value that suits your current needs. If the refrigerator has just been turned on after transportation or long-term defrosting, it is better to start with the minimum value (1 or Min) and gradually increase it. This will allow the system to smoothly enter the operating mode without overload.
☑️ Initial setup algorithm
After changing the position of the regulator, do not expect instant results. Cooling cycle takes time. The compressor takes time to cool the freon, which, circulating through the system, will lower the temperature in the chambers. Typically, complete equalization of the temperature regime takes from 6 to 12 hours, depending on the ambient temperature and the number of products.
The influence of product loading and season on the settings
The temperature regime is not a static parameter; it should be adjusted depending on the season and the fullness of the chambers. In summer, when the room temperature is high, heat flow through the walls of the refrigerator increases. On hot days, it is recommended to move the control knob towards higher values (4 or 5) to compensate for the heating.
In winter, if the refrigerator is in an unheated room or simply in a cold room, the situation changes. At an air temperature below +16°C, the compressor may stop turning on, since it “seems” that it is already cold enough inside. In such conditions, if the model is not equipped with a winter mode, it may be necessary to set the regulator to stronger cooling, but it is better to ensure that the room is not colder than +10°C.
- 🧊 Full load: if the freezer is densely packed with food, the cold lasts longer, but the initial cooling takes time. Set the regulator to 4.
- 🥩 Fresh food: to freeze a large volume of meat or berries, temporarily turn on the super freezing mode (if there is a button) or set the knob to 6-7 for 12 hours.
- 🌡️ Empty refrigerator: if chambers are almost empty, position 2 or 3 is enough, since the heat capacity of the air is small and cold accumulates quickly.
⚠️ Attention: Do not fill the freezer to capacity with food immediately after turning it on. This blocks air circulation and can lead to the fact that the temperature sensor does not calculate the correct temperature, and the compressor will work without stopping.
Table of correspondence of modes and operating conditions
For the convenience of users, we have systematized recommendations for choosing the position of the regulator depending on external factors. Remember that these values are averaged for standard two-chamber models Atlant with mechanical control.
| Handle position | Operating conditions | Expected effect | Recommendation |
|---|---|---|---|
| 1 (Min) | Minimum load, cool room | Energy saving, mild cold | For short-term storage only |
| 3 (Average) | Standard conditions, mixed load | Optimal mode (-18°C) | Recommended for continuous work |
| 5-6 (Max) | Heat, full load with fresh products | Intense freezing | Use temporarily (up to 12 hours) |
| 7 (Max) | Quick freezing mode | Maximum cold, risk of freezing | Only for emergency cases |
Typical problems during setup temperature
Incorrect settings often mask real faults or create them. If you set the regulator to the average value, but the food in the freezer is melting, and there is no condensation on the walls of the refrigerator compartment, the compressor may be faulty. In this case, twisting the knob will not help, you need to call a technician. freon leak or the compressor is faulty. In this case, twisting the handle will not help; you need to call a specialist.
The other extreme is the constant formation of a “coat” of ice even at medium settings. This may indicate a loose door fit or worn sealing rubber. Also, the problem may lie in sticking contacts of the thermostat: it “thinks” that the heat has not yet been gained and does not give a command to turn off the motor.
Sometimes users complain that when the knob is set to 3, the freezer is too warm, and when set to 5, everything freezes. This is a typical sign of an unbalanced system or aging refrigerant. In such cases the only way out is often to find a compromise position between scale divisionssince the mechanical regulator does not have fixed steps and allows you to place the knob in between.
FAQ: Frequently asked questions
What does the red indicator light next to the control knob mean?
The red indicator lights up when the temperature in the freezer rises above a safe level (usually above -12...-15°C). This is an alarm. If the light is constantly on when the refrigerator is on, check whether the door is tightly closed, whether the chamber is overloaded with warm food and whether the thermostat is set correctly.
Is it possible to keep the Atlant refrigerator at maximum (7) all the time?
It is strictly not recommended. The maximum power mode is intended for short-term intensive freezing. Constant operation at the limit leads to rapid wear of the compressor, increased energy consumption and excessive freezing of the evaporator, which impairs heat transfer.
Why does the temperature not change immediately after changing the setting?
The refrigerant takes time to circulate through the system and change the thermal regime of the entire volume of the chambers. In addition, the products themselves have a high heat capacity. It may take 6 to 12 hours to completely stabilize the temperature after adjustment.
How to understand that the thermostat is broken?
The main signs of a malfunction: the refrigerator does not turn on at all (or works without stopping), relay clicks without starting the motor, or lack of response to turns of the regulator knob. If when you turn the knob you do not hear a characteristic quiet click (in silence), the regulator mechanism may be damaged.
