Correct setting of the temperature mode in the refrigeration unit equipment is not just a matter of comfort, but a critical parameter for the safety of products and the durability of the equipment itself. Owners of Belarusian-made household appliances are often faced with the need for precise calibration, since this determines whether vegetables will freeze and milk will not spoil. Atlant refrigerators They are famous for their reliability, but require careful attention to the thermostat settings to ensure an optimal microclimate inside the chambers.
There are many nuances depending on the model of the unit, the number of compressors and the type of control (mechanical or electronic). Incorrectly set values can lead to the formation of a “fur coat” on the walls or, conversely, to insufficient cooling. In this article, we will look in detail at how to set the necessary parameters, what the numbers on the regulator mean, and how to understand that the equipment is operating normally.
Before taking active steps, you need to make sure that the device is installed correctly, is not skewed, and has sufficient clearance from the walls for ventilation. Only in such conditions thermostat will the correct data be shown, and the compressor will not operate in overload mode. Let's look at the basic principles of operation of climate control in these units.
The principle of operation of the thermostat and the scale of values
In most models with mechanical control, such as the series Atlant 4008 or 4502, adjustment is carried out turning the thermostat knob. The control panel usually has a graduated scale, which often causes confusion among users. It is important to understand: the numbers on the scale do not directly indicate degrees Celsius. These are conventional units of cooling power.
The higher the number you set, the below the temperature inside the chamber will be. That is, position “7” means maximum cooling, and “1” means minimum. If the knob is set to “0”, the compressor is completely turned off and no cold is produced. This is a basic principle that needs to be remembered in order to prevent food spoilage.
The optimal mode for everyday use is considered to be the position of the handle between 3 and 4. It is in this range that a balance is achieved between energy consumption and quality of freezing or cooling. When setting the maximum values, the compressor can work almost without stopping, which reduces its resource.
⚠️ Attention: Never set the regulator immediately to maximum after defrosting or loading a large volume of warm food. This will create an extreme load on the motor-compressor, which can lead to its premature failure.
Electronic models, for example, series Atlant XM-6025, have a digital display where the temperature is set directly in degrees. Here the logic is simpler: choose a value and get the result. However, even such systems have their own stabilization delays, which are worth remembering.
Setting up two-chamber models with one compressor
In classic two-chamber refrigerators Atlant with one motor, the cold is distributed unevenly. The main cold is generated in the freezer compartment, and it enters the refrigerator compartment through channels or simply due to convection. The adjustment here is carried out by one common thermostat, which is usually located inside the refrigeration chamber or on the body.
When you turn the knob, you change the compressor shutdown threshold. The temperature sensor (heat-sensitive tube) reacts to the heating of the evaporator. If you turn the knob to the maximum, the compressor will work until it becomes very cold in the freezer, which will automatically lead to For such models there is a golden rule: the setting is made based on the requirements for the refrigerator compartment, since this is where the bulk is stored heat sensitive products. The freezer in such systems usually keeps the temperature below normal if the regulator is set above the middle. freezing of food in the upper compartment.
For such models, there is a golden rule: the settings are made based on the requirements for the refrigerator compartment, since this is where the bulk of heat-sensitive products are stored. The freezer in such systems usually keeps the temperature below normal if the regulator is set above the middle.
If you notice that in the refrigerator compartment food begins to freeze at the back wall, and in the freezer the meat is soft, then the balance is upset. In this case, it is necessary to move the regulator towards decreasing the value. It is also worth checking the tightness of the seal sealing rubberas the suction of warm air disrupts the thermostat settings.
Temperature adjustment in models with two compressors
More modern and expensive models such as Atlant 1700 or 1800 series, equipped with two independent compressors. This allows you to adjust the temperature in each chamber separately, which is a huge plus for the user. The refrigerator compartment has its own thermostat, the freezer compartment has its own.
Independent control makes it possible to use the “Vacation” or “Super Freeze” mode without affecting the adjacent chamber. For example, you can turn off the refrigerator compartment completely, leaving the freezer operating normally. This is convenient if you are away for a long time or if you need to prepare a large number of semi-finished products.
The freezer compartment of two-compressor units often has a quick freezing function. When activated, it lights up yellow indicator, and the compressor operates continuously. You should not keep this mode on for more than 24 hours, as this is an emergency operating mode, not a normal one.
☑️ Checking the settings of two compressors
When setting up two compressors, it is important to monitor energy consumption. If both motors are running at maximum power, your electricity bill could rise significantly. A reasonable setting allows you to save up to 20% of energy compared to the chaotic use of modes.
Features of setting up the No Frost system
Refrigerators Atlant with the system No Frost (or “Full No Frost”) have a fundamentally different air circulation scheme. Here, cold air is forced into the air by a fan, which ensures uniform temperature throughout the chamber. Adjustment in such models is often more accurate, but also more sensitive to air duct contamination.
In models with electronic control, adjustment is made through a panel on the door. You set the target temperature, and the electronics decide when to turn on the compressor and fan. In mechanical versions of No Frost, the principle remains the same: the higher the number, the colder.
A feature of such systems is that they respond faster to door opening. However, if you fill the grocery shelves to capacity, blocking the air circulation holes, the temperature sensor will show incorrect data. This will lead to incorrect operation compressor and possible formation of ice in hidden places.
⚠️ Attention: In No Frost refrigerators, it is strictly forbidden to seal the ventilation holes inside the chamber or tightly fill the shelves with products “to capacity”. This interferes with air circulation and leads to system failure.
If you feel that the food in the No Frost refrigerator compartment is drying out faster than usual, try reducing the cooling intensity by 1 notch. Also check the condition of the drainage system, as a clogged drain can cause a local increase in humidity and temperature.
Table of recommended temperature conditions
In order for products to retain their properties for as long as possible, certain temperature ranges must be observed. Below is a table that will help you navigate the settings for various product groups. This data is relevant for most household models.
| Product type | Recommended temperature (°C) | Storage area | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat and fish | from 0 to +2 | Zero zone / Bottom | 1-3 days |
| Dairy products | from +2 to +4 | Middle shelves | 3-7 days |
| Vegetables and fruits | from +4 to +6 | Bottom drawers | up to 14 days |
| Ready meals | from +2 to +5 | Upper shelves | 2-4 days |
As can be seen from the table, the temperature spread inside the chamber can be significant. That is why it is important not only to adjust the thermostat, but also to correctly distribute food on the shelves. Temperature gradient in the refrigerator is a physical reality that must be taken into account.
Why does the temperature change in different zones?
Cold air is heavier warm, so it sinks down. However, in refrigerators with a fan (No Frost) this effect is smoothed out, but the back wall is always colder due to the proximity to the evaporator.
Use a thermometer to check the actual temperature on different shelves of your unit. Place a regular household thermometer in a glass of water and place it on the middle shelf overnight. This will give the most accurate picture of what is happening inside.
Common problems and solutions
Even with proper settings, users may encounter situations where the refrigerator behaves strangely. For example, the compressor turns on too often or, conversely, remains silent for hours. Often the reason lies not in a breakdown, but in incorrect operation or settings.
If condensation or ice crust appears on the products, and the regulator is set to minimum, the problem may be door seal. The rubber band may have dried out, become dirty, or become deformed. Check the tightness with a sheet of paper: hold it with the door and try to pull it out. If the sheet slips out easily, the seal requires replacement or cleaning.
If the refrigerator hums and does not turn off, and the temperature does not drop below +10 degrees, there may be a refrigerant leak or a thermostat failure. In such cases, self-adjustment with the handle will not help - you will need to call a technician.
It is also worth considering external factors. If the refrigerator is located next to the radiator or is exposed to direct sunlight, the thermostat will “think” that the chamber is too warm and will cause the compressor to work harder. In such conditions, it is almost impossible to set the correct temperature.
Frequently asked questions (FAQ)
Why does ice freeze on the back wall in the Atlant refrigerator?
This can happen for several reasons: the temperature is set too low (the regulator is at maximum), the door is often opened, or warm food gets into the chamber. It is also possible that the seal may fail. Try increasing the temperature by 1-2 notches.
What temperature should be in the freezer of a two-chamber Atlanta?
The optimal temperature for long-term storage of food in the freezer is considered to be -18°C and below. If you have a mechanical control, this usually corresponds to the position of the handle in the middle or slightly higher (3-4 divisions out of 7).
Is it possible to set the temperature in the Atlant refrigerator to zero?
Position “0” on the thermostat means forced shutdown of the compressor. The cold will stop being produced, and the temperature inside will begin to rise to room temperature. This is used only during defrosting or prolonged downtime of the equipment.
How to understand that the refrigerator thermostat is faulty?
Main signs: the refrigerator does not turn on at all (if there is voltage in the network), or it works without interruptions, without gaining temperature. Also, a symptom may be a sudden turning on and off of the motor every few minutes.
Does the amount of food affect the temperature setting?
Yes, a full refrigerator keeps the temperature more stable, but it takes longer to reach the operating mode after loading. An empty refrigerator cools faster, but when the door is opened, the temperature in it fluctuates more. It is recommended to keep the chambers filled at least 50-60%.
