Correct adjustment of climatic parameters inside the chambers is the foundation long service life of household appliances and guarantee of product safety. Owners of Belarusian equipment are often faced with the need for calibration after the first installation or seasonal changes in the indoor climate. Incorrect operating mode of the compressor leads either to spoilage of supplies, or to the formation of an ice crust and excessive energy consumption.
Brand models Atlant are equipped with various types of controls: from classic mechanical knobs to modern electronic displays. Understanding the principles of operation thermostat will allow you to avoid common operating mistakes. In this article we will analyze the nuances of setting for different series of equipment.
Before you start changing the settings, you need to let the unit settle after transportation and initial startup. Sudden jumps in values can disorient the automation or lead to incorrect operation of the sensors. Let's look at how to find the optimal balance for your needs.
The principle of operation of a mechanical thermostat
Most classic models are equipped with a rotary knob located inside the refrigerator compartment or on the body. The numbers on a scale from 1 to 7 (or from Min to Max) do not indicate degrees Celsius, but the intensity of the compressor. The higher the number, the lower the temperature inside the chamber and the longer the motor runs.
Setting the regulator to the “7” or “Max” position means that the compressor will work almost non-stop, trying to achieve the lowest possible values. This is only permissible in fast freezing mode or at very high ambient temperatures in the room. Constant operation in this mode leads to accelerated wear of parts.
The optimal factory value for everyday use is considered to be position 3 or 4. This range provides a balance between efficient cooling and energy efficiency. If you have just installed a new refrigerator, start with these indicators.
Setting up electronic control and display
Modern series, such as Atlant XM-4425 or XM-6025, are equipped with digital control panels, often hidden behind a door or located on the outside of the case. Here the adjustment occurs with an accuracy of a degree, which gives the user complete control over the microclimate. To activate the menu, you often need to press and hold the setup button for several seconds.
When changing parameters, the numbers on the display flash, signaling the transition to editing mode. Using the Up and Down buttons allows you to select the desired value.
Some models allow you to independently adjust the climate in the refrigerator and freezer compartments. This is especially convenient if you have loaded the compartment with a large volume of fresh food that requires deep freezing, while the upper compartment is only storing drinks. Separate control helps optimize energy consumption.
Super freeze mode: when and how to turn it on
The “Super freeze” function (often indicated by a snowflake or button Super Freeze) is designed to quickly lower the temperature in the freezer to extreme values (about -24°C and below). This mode is necessary when loading a large amount of fresh, unfrozen products, so that they pass the crystallization point quickly and maintain the structure.
This mode should be turned on in advance, several hours before the planned loading of products, or simultaneously with them. In mechanical models, for this purpose the handle is moved to the extreme position; in electronic models, the corresponding function is activated on the panel. Automatic shutdown occurs after a certain time (usually from 8 to 72 hours depending on the model).
⚠️ Attention: Do not leave the super freeze mode on all the time. Long-term operation of the compressor at its maximum without interruption can lead to overheating of the motor windings and a reduction in the service life of the equipment.
After the products have frozen, it is necessary to return the settings to standard mode. If this is not done, an excessive layer of frost will form in the freezer and will waste extra electricity. In models with No Frost this will also accelerate the wear of the defrosting system.
Table of optimal temperatures for storage
Understanding what conditions are required for different types of products will help set the correct values on the thermostat. There is no universal "for everything" value, so it is important to know the average storage requirements. Below is reference information for setting.
| Product type | Recommended temperature | Shelf life (approx.) | Refrigerator area |
|---|---|---|---|
| Fresh meat and fish | 0°C.. +2°C | 1-2 days | Zero zone / Bottom |
| Dairy products | +2°C.. +4°C | 3-5 days | Middle shelf |
| Vegetables and fruits | +4°C.. +8°C | 3-7 days | Drawer below |
| Ready meals | +2°C.. +5°C | 1-2 days | Top shelf |
If you set the temperature to +5°C on the display, this does not guarantee that on all shelves it will be exactly +5°C. It is always colder in the upper part of the chamber, closer to the freezer, and warmer in the door and lower drawers. Take this gradient into account when arranging food.
Why is the temperature different in different zones?
Cold air is heavier than warm air, so it sinks down. However, in modern models with forced circulation (No Frost), the fan mixes the flows, making the distribution more uniform, but the gradient at the door is still maintained due to opening.
The influence of external factors on the settings
The environment has a direct impact on the operation of the refrigeration circuit. If the refrigerator Atlant is installed near a gas stove, radiator, or in direct sunlight, the thermostat will be forced to work more intensely. In such cases, the standard setting “3” or “+4°C” may not be enough.
In the summer, when the room temperature exceeds +25°C, heat transfer from the condenser is difficult. The compressor turns on more often and runs longer. During this period, it is recommended to shift the regulator towards lower temperatures (increase the number on the mechanics or lower the degrees on the electronics) to compensate for the heating.
In winter, the situation is the opposite. If the kitchen is cool, the compressor may rarely turn on, which will lead to an increase in the temperature inside the chambers above the permissible level. However, if the refrigerator is in an unheated room (balcony, garage), operation may be prohibited by the instructions due to solidification of the oil in the compressor.
Typical errors during adjustment
One of the most common mistakes is an attempt to cool hot products by turning the regulator to the maximum. This leads to the formation of a “snow coat” on the evaporator and false sensor readings. The compressor will run empty until the food cools down naturally.
Another mistake is changing the settings frequently. Thermal stabilization takes time. If you change the position of the handle in the morning, do not expect results in an hour. Give the system 4-6 hours to reach the new mode. Constant manipulations only disrupt the operating algorithms (in electronic models) and wear out the mechanics.
⚠️ Attention: Never use sharp objects to chip ice when setting up. Damage to the evaporator (tubes inside the chamber) will lead to freon leakage and expensive repairs, which are often not economically feasible.
Also, users often ignore how tightly the doors are closed. If the seal is worn out or the door is warped, the cold will escape, and the thermostat will “think” that the chamber is warm and will constantly drive the motor. Check the fit of the doors before turning the settings.
Diagnostics: when the settings do not help
There are situations when you have set the correct temperature, but the refrigerator Atlant behaves strangely: it either freezes too much, turning vegetables into ice, or does not keep the cold at all. If the regulator is set to “3” or “+4°C”, and it is clearly warmer or colder inside, the thermostat or sensor itself may be faulty.
In mechanical models, a sign of a malfunction of the thermostat may be the absence of a click when turning the knob or, conversely, constant operation of the compressor even when the knob is turned to “0”. In electronic models, error codes may light up on the display, for example F4 or F7, indicating problems with temperature sensors.
☑️ Checking the serviceability of the system
If you suspect damage, do not try to disassemble the device yourself, especially if it is under warranty. Unqualified tampering with the electrical circuit or refrigeration circuit will void the manufacturer's warranty. Contact an authorized service center for professional diagnostics.
Why did the refrigerator start working louder after adjusting the temperature?
When switching to a lower temperature (increasing cold), the compressor is forced to work longer without stopping in order to cool the volume of air and food. This creates a feeling of constant noise. In addition, the refrigerant may circulate more actively through the pipes, creating gurgling sounds. If the noise is not accompanied by vibration or knocking, this is a normal adaptation process.
Is it possible to change settings while the refrigerator is running?
Yes, you can change the thermostat settings at any time without disconnecting the device from the network. The mechanics can be turned smoothly, and the electronic buttons can be pressed according to the instructions. However, a sharp change from minimum to maximum (and back) creates a stressful load on the system, so it is recommended to do this gradually.
What to do if ice freezes in the Atlant refrigerator with the correct settings?
Ice formation at the correct temperature (about +3..+4°C) most often indicates problems with tightness (the door does not close well, is torn seal) or that you are loading high-moisture products into the chamber without a lid. It is also possible that the drainage hole through which moisture should escape is clogged.
How often should you check the temperature in the refrigerator?
It is enough to check seasonally: with the onset of summer heat and winter cold. It is also worth checking after defrosting, general cleaning, or if you notice a change in the quality of food storage (milk quickly sours, meat loses color).
