Correct setting of the temperature regime is the key to the safety of food and the long service life of the compressor of your household appliance. Owners of Belarusian brand equipment are often faced with the need to change the cooling strength, especially when the seasons change or after the chambers are fully loaded. Incorrect settings can lead to food spoilage or the formation of excessive ice.
The adjustment process directly depends on the type of control installed in your model Atlant. There are mechanical systems with rotary knobs and modern electronic modules with a digital display. Understanding the operating principle of a particular regulator will allow you to avoid mistakes and configure the device as efficiently as possible.
In this article we will analyze in detail the algorithms of action for different series of refrigerators, explain the meaning of the numbers on the scale and answer frequently asked questions about operation. A competent approach to thermoregulation will help you optimize energy consumption and maintain the freshness of products.
The principle of operation of thermostats in different models
The main element responsible for the microclimate inside the chamber is the thermostat. Classic models Atlant, such as the MXM-1700 or 1800 series, use a mechanical device. It consists of a bellows tube, sensitive to changes in refrigerant pressure, and a contact group that opens the compressor power supply circuit.
Electronic control systems, characteristic of newer lines with technology No Frost or multi-flow cooling, work differently. Here, temperature sensors (thermistors) transmit data to the main controller, which independently decides whether to turn the motor on or off. The user only sets the desired parameters through the panel.
Differences in design also dictate different approaches to calibration. Mechanics require “by eye” and experienced selection of the position of the handle, while electronics allows you to set the exact value in degrees Celsius. An error in setting a mechanical regulator is less critical, but requires more time to stabilize the mode.
⚠️ Attention: The internal structure of thermostats from different manufacturers may differ. If you are planning to replace the sensor, make sure that the new element has similar temperature response characteristics, otherwise the operating modes of the compressor will be disrupted.
Setting up a mechanical thermostat
Owners of refrigerators with a rotary handle inside the refrigerator compartment need to understand the logic of the digital scale. Typically it varies from 1 to 7 or from Min to Max. It is important to remember: the number does not indicate degrees Celsius, it indicates the cooling intensity.
The higher the number you set, the colder it will be in the chamber. Setting the knob to the “7” or “Max” position causes the compressor to work almost non-stop, which can lead to freezing of food and icing of the evaporator. On the contrary, position “1” minimizes motor operation.
For standard operating conditions, it is recommended to set the regulator to the middle position - usually numbers 3 or 4. This provides a balance between sufficient cooling and economical power consumption. Sharp switching of the knob is undesirable; give the system time to stabilize.
What is hidden behind the thermostat knob?
Inside the mechanical thermostat there is a bellows filled with freon or other gas condensate. When the temperature in the chamber changes, the gas contracts or expands, moving the membrane, which opens or closes the electrical contacts.
If you notice that the food in the refrigerator begins to freeze even at medium settings, try reducing the value by one scale division. Conversely, if the milk quickly sours and the chamber is warm, add one step towards increasing the power.
Temperature adjustment in electronic models
Modern refrigerators Atlant are equipped with convenient displays located on the outer door or inside the chamber. Control is carried out using touch buttons or mechanical keys under the screen. Here you operate with specific temperature values, which greatly simplifies the task.
The optimal temperature for the refrigerator compartment is considered to be the range from +3 to +5 degrees Celsius. For the freezer, especially in fast freeze mode or when fully loaded, you can set the value to -18 or -20 degrees. The electronics will automatically turn off the compressor when the specified threshold is reached.
Some models allow you to activate special modes, such as “Vacation” or “Super Freeze”. Mode "Vacation" puts the refrigerator compartment into economy mode (about +15°C), preventing the appearance of odors while the freezer continues to operate. “Super freezing” turns on the motor at maximum power for a certain time.
A long press on the temperature adjustment button is often required to access the settings menu. After the numbers on the display flash, use short presses to select the desired value. Confirmation usually occurs automatically a few seconds after the last action.
Seasonal adjustment of operating modes
Ambient temperature significantly affects the operation of refrigeration equipment. In summer, when the apartment is hot, heat inflows increase and the compressor takes more time to cool the chambers. In winter, the situation is the opposite, but there are some nuances, especially for equipment installed on unheated balconies.
In the summer, it is recommended to slightly increase the cooling power (translate the mechanics to a higher number or lower the degrees in the electronics). This compensates for the heating of the case from the warm air in the room. However, you should not set the maximum values so as not to overload the compressor.
In winter, if the refrigerator is in a warm kitchen, the load can be reduced. But if the equipment is located in a cold room (below +10°C), problems may arise with starting the motor or defrosting the freezer in single-compressor models. Many modern Atlant have a climate class SN, allowing operation at +10°C.
Monitor the behavior of the device as the seasons change. If you notice an increase in power-on cycles or, conversely, too infrequent starts, recalibrate. The stability of the temperature inside the chamber is more important than strictly following the numbers on the scale.
Table of recommended temperature conditions
To quickly navigate the settings of various storage zones, use the table below. It will help set the correct parameters for different types of products, ensuring their long-term preservation and safety.
| Storage area | Recommended temperature | What to store | Setting features |
|---|---|---|---|
| Refrigeration camera | +3...+5 °C | Dairy products, ready meals, vegetables | Standard position of the regulator |
| Zero zone (Fresh) | 0...+2 °C | Fresh meat, fish, herbs | Requires accurate settings, often a separate compartment |
| Freezer compartment | -18...-24 °C | Frozen semi-finished products, meat, berries | Long-term storage without loss of properties |
| Door shelves | +5...+7 °C | Sauces, drinks, eggs, medicine | The warmest zone, not for perishables |
Please note that the temperature in different parts of the same chamber may differ. It is always warmer on the upper shelves than on the lower ones, and it is colder near the back wall than near the door. Distribute products taking into account these thermal zones.
Using a probe thermometer or a separate household thermometer placed on a shelf will help you monitor the actual temperature inside and adjust the regulator settings with high accuracy.
Common mistakes when setting up
One of the most common mistakes is setting the maximum cooling level immediately after purchase or defrosting. Users think that this will cool the chamber faster, but in fact it only creates excess load on the engine without significantly speeding up the process.
The rule about filling the chambers is also often ignored. An empty refrigerator cools down faster, but holds the cold worse when the door is opened. A box filled too tightly with food blocks air circulation, which leads to local overheating and incorrect operation of sensors.
⚠️ Attention: Do not adjust the thermostat if the refrigerator door has been open for a long time or you have just loaded a large amount of warm food. products. Wait for the temperature to stabilize (usually 3-5 hours) before drawing conclusions about the need for adjustment.
Another mistake is changing settings frequently. The thermostat needs time to “sense” the change and react. By turning the knob back and forth every half hour, you disrupt the operating algorithm and do not allow the system to enter stationary mode.
☑️ Checking the correct settings
Diagnostics of thermostat faults
Sometimes the problem lies not in incorrect settings, but in the breakdown of the control device itself. If the knob turns without a characteristic click, and the compressor does not start even at maximum, the mechanical thermostat may have failed mechanical thermostat.
In electronic models, a sign of a malfunction may be a discrepancy between the display readings and reality (for example, it shows +3°C, but it is clearly warmer inside) or the chaotic turning on of the motor. In such cases, simple adjustment will not help; diagnostics of the sensors will be required.
If the refrigerator turns on and off too often (short cycles), this may indicate a loss of tightness of the thermostat bellows or displacement of the sensitive tube. In this case, replacement of the unit is necessary.
The influence of product placement on the temperature regime
The correct layout of products is half the success in maintaining the desired climate. Hot or warm dishes are placed only after they have cooled to room temperature. Heat getting inside causes the thermostat to “think” that the chamber is hot and turn on the motor at full power.
It is important not to block the ventilation holes. In models with a system No Frost and multi-flow cooling, air must circulate freely throughout the entire volume. Closed containers or bags placed against the back wall can block the flow of cold air.
Use containers and sealable containers. Opened products release moisture, which increases the humidity in the chamber and can lead to more frequent defrost cycles or the formation of a fur coat on the evaporator, which indirectly affects the temperature regime.
How often do you need to defrost the Atlant refrigerator to maintain the mode?
Models with manual defrosting require unplugging and defrosting at least once every 4-6 months. A thick layer of ice on the evaporator acts as a heat insulator, which is why the temperature sensor does not “feel” the cold, and the compressor works longer, trying to cool the chamber. No Frost systems defrost automatically, but it is also recommended to wash and dry them once a year.
Why is it too cold in the refrigerator compartment, although the regulator is at a minimum?
If the knob is set to "1" or "Min" and the food freezes, there are two main reasons: a malfunction of the thermostat itself (it does not open the circuit) or a problem with door seal. If the seal does not retain heat, warm air constantly enters the chamber, causing the motor to work harder, but at the same time, due to a draft, the sensor may not work correctly. It is also possible for the cold air supply damper to jam in two-chamber models.
Is it possible to use an external thermostat for a refrigerator?
Technically, it is possible to connect an external thermostat (thermostat socket), but for modern Atlant models this is not recommended. The refrigerator electronics may perceive frequent power outages as an emergency and block the operation of the compressor or reset the settings. In addition, this violates the defrost algorithms. It is worth using external regulators only on older, fully mechanical models, if a standard thermostat cannot be found.
What to do if, after adjustment, the temperature changes very slowly?
Inertia is a normal property of refrigeration equipment. Complete stabilization of the temperature after changing the settings can take from 6 to 12 hours, and sometimes up to a day. This depends on the volume of the chamber, the number of products and the ambient temperature in the room. Do not rush to turn the handle again, give the device time to react.
