Correct temperature adjustment is the foundation for long and high-quality operation of any refrigeration equipment. For owners of Belarusian equipment Atlant this issue is especially acute, since the shelf life of products and the absence of ice on the walls of the chambers directly depend on the correct settings. An incorrectly set mode can lead to rapid spoilage of food or, conversely, to freezing of vegetables and fruits.
In this article we will analyze in detail all the nuances of setting climate control in various models of refrigerators Atlant. You will learn how mechanical thermostats work, how they differ from electronic control systems, and what values are optimal for different seasons of the year. Understanding the principles of operation of your unit will help you avoid common operating mistakes.
Before taking active steps, you need to determine the type of control in your model. Thermostat design can differ radically depending on the year of manufacture and series of the device. In older models you will see a rotary knob, while in modern ones you will see a digital display or touch buttons. The algorithm for your further setup steps will depend on this factor.
Determining the type of control and location of the regulator
The first step should always be a visual diagnosis of the control panel. In most classic models Atlant, especially in the MX and MXM series, the regulator is a round knob located inside the refrigerator compartment. Usually it is located in the upper right or left corner, sometimes hidden behind decorative plastic or a lampshade. The scale can contain numbers from 1 to 7 or from Min to Max.
Modern two-chamber refrigerators are often equipped with electronic control unit. In this case, there is no handle inside the camera, and all settings are displayed on the display located on the outer door or on the top of the body. The presence of a display greatly simplifies the task, since you see the exact temperature in degrees Celsius, and not abstract divisions. However, even in such models there may be additional mechanical dampers to regulate air flow.
⚠️ Attention: Never try to forcefully turn the mechanical thermostat knob if it is jammed. A sudden force may break the plastic stem or damage the internal membrane, which will require replacement of the entire assembly.
If you cannot find the regulator, refer to the technical documentation for your model Atlant. The location of the controls is strictly regulated for each series, and knowing the exact modification will help you quickly navigate the camera space. Sometimes the regulator is combined with a defrost button or a "Super Freeze" mode switch.
Settings mechanical thermostat
Mechanical thermostat is a reliable and simple mechanism that opens the electrical circuit when the set temperature is reached. Turning the knob clockwise increases the spring tension, causing the compressor to work longer and cool the chamber more intensively. The values on the scale do not correspond to degrees Celsius, but indicate the degree of cooling: the higher the number, the colder.
For standard food storage mode, the optimal position of the knob is at number 3 or 4. This corresponds to a temperature of about +4..+5°C in the main chamber. Setting the value to 6 or 7 puts the refrigerator in maximum power mode, which is only justified during initial startup or quick freezing of a large volume of food. Constant operation at maximum leads to accelerated wear of the compressor.
It is important to consider that mechanical systems have a certain inertia. After turning the knob, the actual temperature in the chamber does not stabilize immediately, but within several hours. Therefore, you should not turn the regulator every 15 minutes in an attempt to get results faster. Give the system time to complete the cycle and reach the specified mode.
There are also models with separate adjustment, where one handle is responsible for the refrigerator compartment, and the second (often smaller) for the freezer. In such cases temperature balance is set consistently: if you increase the freezing power, the load on the system increases, and the temperature in the upper compartment may also change.
Adjustment in models with electronic control
The electronic control system allows you to set the temperature with an accuracy of one degrees. In refrigerators Atlant with a display (XM series, some models of two-compressor refrigerators), the settings are carried out through a panel on the door. Usually the process looks like this: you need to press the chamber selection button (refrigerator or freezer), after which the flashing numbers will allow you to change the value using the “+” or “-” buttons.
The advantage of electronics is the ability to set an exact value, for example, +3°C for storing meat or +7°C for fruit. Also, such systems often have a child lock function that prevents accidental changes to settings. If the lock icon lights up on the display, press and hold the corresponding button for 3-5 seconds to unlock.
| Mode | Temperature (Refrigerator) | Temperature (Freezer) | Purpose |
|---|---|---|---|
| Eco / Standard | +4°C.. +5°C | -18°C | Daily storage |
| Cooling | +2°C.. +3°C | -18°C | Perishable foods |
| Super freezing | +4°C | -24°C (temporary) | Fresh food freezing |
| Holiday | +10°C.. +15°C | Off / -18°C | Long absence |
When setting up the electronic unit, it is important not to allow simultaneous changes parameters in both cameras, if the model allows this. It is better to first set the mode for the refrigerator compartment, wait for stabilization, and only then adjust the freezer parameters. This will help the control system correctly distribute the compressor resources.
☑️ Checking the electronic settings
Optimal temperature conditions for different products
Understanding which products are stored where helps to configure climate mode as efficiently as possible. The Atlant refrigerator compartment, like most modern chambers, has zones with different temperatures. The upper shelves are warmer, the lower ones are colder. Knowing this, you can correctly distribute supplies without overloading the compressor with unnecessary work.
For dairy products, ready meals and sausages, the ideal zone is the middle shelves, where the temperature remains stable around +4°C. It is better to place meat and fish that are planned to be cooked in the next 24 hours on the lowest shelf, directly above the vegetable drawer, where the air is coldest. Fruits and vegetables require higher humidity and a temperature of about +8°C, so their place is in sealed boxes at the bottom of the chamber.
⚠️ Attention: Do not fill the refrigerator with food close to the back wall. There are air circulation channels or an evaporator. Blocking the air supply will lead to local hypothermia and the formation of an ice crust.
If you notice that the milk is turning sour faster than usual, and vegetables are losing their elasticity, the temperature in the chamber may be too high. In this case, it is necessary to turn the regulator knob towards higher values (or reduce the number on the electronic display if it indicates degrees). Conversely, if food freezes at the rear wall, the cooling power should be reduced.
Using the Super Freeze mode
The mode Super Freeze is designed for quickly freezing large quantities of fresh food. When this function is activated, the refrigerator compressor Atlant begins to work continuously, ignoring the thermostat readings, in order to quickly lower the temperature in the freezer to -24°C and below. This allows you to preserve the cell structure of the product and prevent loss of juice during defrosting.
In mechanical models, this mode is often activated by a separate red button or switch next to the thermostat. When turned on, the corresponding indicator lights up. After freezing a fresh portion (usually it takes from 12 to 24 hours), the mode must be turned off manually.
What happens if you forget to turn off Super Freeze?
If you leave the super freeze mode on for a long period of time (weeks), a thick layer of ice will form in the freezer compartment, and the compressor will work for wear without interruption. This will significantly reduce the service life of the equipment and increase energy consumption. In some models with electronics, this mode turns off automatically after a day, but in mechanical models it is only turned off manually.
In electronic models, the super freezing function may have a timer. You activate the mode, and the system itself will turn it off after a specified time (for example, after 8 or 12 hours). This is a more convenient option that eliminates the human factor. Follow the display on the panel: a flashing snowflake icon usually indicates that the mode is running, and a lit one indicates its completion or the need to turn off.
Seasonal adjustment and external factors
The ambient temperature directly affects the operation of the refrigerator. In summer, when the apartment is hot, heat exchange worsens and the compressor takes more time to cool the chambers. During this period, it may be necessary to set the regulator to more powerful cooling (closer to maximum). In winter, on the contrary, when the room is cool, the load can be reduced by turning the knob towards the minimum.
However, it is worth taking into account the minimum permissible operating temperature specified in the passport Atlant. Most models are not designed to operate at temperatures below +10°C (for example, on an unheated balcony). Under such conditions, the oil in the compressor thickens and starting the engine may become impossible or lead to breakdown. If you plan to operate equipment in non-standard conditions, make sure that the model has the appropriate climate class.
The temperature inside is also affected by the frequency of door openings. If the refrigerator is in a kitchen where there is a lot of cooking or children often look into it, the internal temperature will fluctuate more. In such cases, it makes sense to set the average power value so that the system has time to compensate for heat inflows, but does not work idly.
Frequent problems and their solutions
Sometimes users are faced with a situation where adjusting the temperature does not give the expected result. In the refrigerator Atlant this may be due to several factors. First, check the tightness of the door seals. If the rubber band is worn out or dirty, the cold will evaporate and the compressor will thresh without stopping, not reaching the desired temperature.
Secondly, the cause may be a malfunction of the thermostat itself. If you do not hear a click when you turn the knob, even at extreme values, or if the refrigerator does not turn on/off at all, most likely the sensor has failed. In electronic models, erroneous display readings may indicate problems with the control module or NTC sensors.
- 🔍 Check that the ventilation holes are not blocked by food.
- 🌡️ Give the refrigerator 5-6 hours after adjustment to stabilize the mode.
- 🧊 Make sure that there is no thick layer of ice in the freezer compartment (more than 5 mm).
- 🔌 Check the voltage - if the voltage is low, the compressor may not start.
If simple adjustment methods do not help, and the temperature in the chamber does not correspond to the set values, professional diagnostics may be required. Repairing the refrigerant system or replacing the thermostat yourself requires special skills and tools. Do not ignore signs of malfunction, as operation in abnormal mode quickly disables the equipment.
Why does the Atlant refrigerator not maintain the temperature after adjustment?
There may be several reasons: freon leak, malfunction of the thermostat, problems with the compressor, or a banal violation of the chamber seal. It is also worth checking whether the defrost button (if there is one) is stuck, which forcibly turns off the heating of the evaporator or changes the operating cycle.
Is it possible to regulate the temperature in a working refrigerator?
Yes, the mechanical thermostat can be turned at any time. Electronic settings also change on the fly. However, sharp changes in settings (from minimum to maximum) are undesirable for the compressor. It is better to change the parameters gradually.
What temperature should be in the Atlant freezer?
The optimal temperature for long-term storage of food in the freezer is considered to be -18°C. In this mode, most bacteria are inactive, and products retain their properties for up to 12 months.
