Correct adjustment of the climate conditions inside the refrigeration chamber is the foundation on which the safety of products and the durability of the unit itself are based. Many owners of household appliances Atlant are faced with a situation where food in one part of the chamber freezes, and in the other, on the contrary, quickly deteriorates due to lack of cold. Understanding the operating principles of the thermostat allows you not only to eliminate this imbalance, but also to significantly reduce energy consumption.
In refrigerators Atlant the temperature control system can be implemented differently depending on the model and year of manufacture. There are mechanical regulators with a rotary knob, electronic panels with a display, and combined options. Incorrect adjustment often leads to increased work of the compressor, which causes premature wear of the motor. That is why it is important to understand the nuances of setting up your particular model.
Before taking active steps, you need to determine the type of control of your device. This is a key point, since the action algorithms for mechanics and electronics are radically different. Incorrect actions when setting up the electronic unit may lead to the need to reset the settings or even call a technician. In this article, we will analyze in detail all aspects of the settings so that you can confidently control the climate in your refrigerator.
Principles of operation of the thermostat in different models
The main element responsible for maintaining the set temperature is thermostat (or thermostat). Classic models of Atlant refrigerators, such as the series MXM or KSH, use a mechanical regulator. It is a device that responds to changes in temperature in the evaporator or directly in the air environment of the chamber. When the temperature rises above the set threshold, the contacts close, starting the compressor.
In more modern models with a system No Frost or electronic control, the process is controlled by temperature sensors that transmit signals to the control module. There is no direct mechanical circuit break here, everything happens programmatically. The user sets the desired parameter, and the “brain” of the refrigerator decides when to turn the motor-compressor on and off. This provides a more stable climate, but requires an understanding of the digital logic of the device.
⚠️ Attention: In models with two compressors (separate for the refrigerator and freezer compartments), the temperature in each chamber is adjusted independently. Do not try to adjust the general mode if you have a two-compressor system.
It is important to consider that mechanical thermostats are not calibrated in degrees Celsius, but in conventional units (from 1 to 7 or from Min to Max). The number 1 means the least cooling, and 7 means the maximum. This often causes confusion as users mistakenly believe that the number indicates a specific temperature. In reality, this is only the degree of intensity of the compressor.
- 🔹 Mechanical regulators work based on the expansion and compression of gas or liquid in a sensitive element.
- 🔹 Electronic systems use thermistors that change their resistance depending on the heating.
- 🔹 Inverter compressors in new Atlant models allow you to smoothly regulate the power, and not just turn on and off.
Setting up a mechanical thermostat
If there is a round knob with divisions on the front panel of your Atlant refrigerator, then you are dealing with mechanical control. This is a reliable and time-tested system that rarely fails, but requires periodic manual adjustments. Adjustment is made by turning the knob to the right (increasing cold) or left (decreasing cold).
The average value is considered the optimal position for year-round use. For most Atlas models, this is a division 3 or 4 out of seven possible ones. Setting the regulator to position 7 (Max) forces the compressor to work almost without stopping, which can lead to freezing of food and overheating of the motor. Conversely, the position 1 may not be enough for high-quality cooling in hot weather.
The setup process cannot be rushed. After each turn of the knob, you must wait several hours for the temperature to stabilize. Only after this can you evaluate the result using a thermometer placed in a glass of water on the middle shelf. Sharp switching can disorient the system, especially if balance has not yet been established in the camera.
☑️ Checking the mechanical settings
There is a common misconception that in winter you need to set the knob to minimum, and in summer to maximum. This is not true for Atlant refrigerators unless they are equipped with a special winter mode (which is rare). In a room with room temperature (+18...+25°C), the regulator should be in its normal position. Changing the position of the knob is only required when the season changes, if the air temperature in the room changes significantly.
What happens if you set the knob to 7 (Max)?
Continuous operation of the compressor will lead to the formation of an ice crust on the back wall, drying out of food and a significant increase in energy bills. In addition, the motor's life will be exhausted faster.
Temperature control in electronic models
Electronically controlled Atlant refrigerators, often equipped with a display on the door, provide the user with more precise control tools. Here you operate in specific degrees Celsius. The standard factory setting is usually +3...+4°C for the refrigerator compartment and -18°C for the freezer. Changing these parameters is done through touch buttons or keys on the control panel.
To change the temperature in the refrigerator compartment, you usually need to press the button with the thermometer or snowflake icon. Holding the button for 3-5 seconds puts the system into editing mode, after which the flashing numbers allow you to select the desired value using the “+” and “-” buttons. In some models Atlant XM-4425 or XM-6025 the sequence of actions may differ, so it is always useful to look at the instructions for the specific model.
Electronics allows you to implement the “Vacation” or “Super Freeze” function, which temporarily changes the standard operating algorithm. The "Super Freeze" mode (Super Freeze) turns on the compressor for continuous operation to quickly freeze fresh products, but it cannot be kept on for longer than 24-48 hours, otherwise the system may go into error or damage the products.
| Operating mode | Temperature (HC) | Temperature (MK) | Recommendation |
|---|---|---|---|
| Standard | +3...+5°C | -18...-20°C | Daily use |
| Economy | +5...+7°C | -15...-18°C | Light load |
| Super freezing | No changes | -24...-26°C | Only for fresh products |
| Vacation | +10...+15°C | No changes | For long absence |
A feature of electronic models is the presence of child protection. If the control panel does not respond to touches, the lock may be activated. Usually it is removed by long (about 5 seconds) pressing the button with the image of a lock. This prevents small children from accidentally changing the settings or when wiping with a damp cloth.
Optimal temperature conditions for products
Correct temperature adjustment is not just comfort, it is safety. Different groups of products require different storage conditions. In Atlant refrigerators, thanks to the air circulation system, the temperature may vary slightly on different shelves, so it is important to know where to store what.
Dairy products, meat and fish are the most demanding of cold. The ideal temperature for them is +2...+4°C. At higher values, bacteria begin to actively multiply in them, and at lower values, the product may lose its structure or freeze. Vegetables and fruits, on the contrary, are better preserved at +5...+8°C, so it is recommended to place them in special drawers at the bottom of the chamber.
- 🥛 Dairy products: require stable cold, do not place them on the door where the temperature fluctuates.
- 🥩 Fresh meat and fish: store on the bottom shelf closer to the back wall, where it is coldest.
- 🥦 Vegetables and herbs: feel optimal in the freshness zone or lower drawers with high humidity.
⚠️ Attention: Be sure to pack ready-made dishes and products with a strong odor (fish, smoked meats) in airtight containers. The No Frost system actively circulates air, spreading odors throughout the entire volume of the chamber.
The freshness zone (if it is provided in your Atlant model, for example, in the series Premium) is a separate compartment with a temperature of about 0...+1°C and high humidity. Here you can store chilled meat or fish for several days without freezing. Adjusting the dampers in this zone allows you to adapt it to a specific type of product.
Typical errors during setup and their consequences
One of the most common mistakes is overloading the refrigerator compartment with warm products. If you put a pot of soup or a package of just purchased food at room temperature in the refrigerator, the sensor will record a sharp increase in temperature. In response to this, the system (especially the mechanical one) will force the compressor to work hard, trying to cool the volume. This can lead to the formation of a “fur coat” on the evaporator, even in models with No Frost, if the system does not have time to thaw.
Another mistake is frequent changes in settings. Users, seeing that the milk has turned sour, immediately turn the knob to maximum. This cannot be done. You must first analyze the reasons: whether the door closes tightly, whether the ventilation holes are clogged with food, whether the refrigerator is located next to the radiator. Blindly increasing the cold without addressing the root cause will only make the situation worse.
Improper placement of food also blocks air flow. In Atlant refrigerators with the No Frost system, cold air is supplied through special channels. If you press the shelves tightly against the back wall, the circulation will be disrupted, and the temperature will be critically different in different corners of the chamber. There should be a gap of at least 2-3 cm between the products and the back wall.
Ignoring seasonal factors also plays a role. In the summer, when the apartment is hot, it is more difficult for the refrigerator to release heat through the condenser (the grille at the back). At this time, you should not set the regulator to minimum, hoping to save money - the food will spoil. In winter, if the room is cool, the load on the compressor drops, and the operating mode can be slightly weakened.
Diagnostics: when adjustment does not help
There are situations when you set the regulator correctly, but the temperature does not correspond to the set one. If the knob is set to “4”, and the chamber is +10°C or, conversely, everything is frozen at minimum, this is a signal of a malfunction. First of all, check the door seal: if it is worn out or dirty, the cold will escape and the refrigerator will not be able to gain temperature.
Another common reason is the failure of the thermostat itself. In mechanical models, this manifests itself in the fact that the compressor either does not turn on at all or works without stopping, regardless of the position of the handle. In electronic models, it may be necessary to replace the temperature sensor, which may have oxidized or broken.
It is also worth paying attention to the defrosting system. If the evaporator is covered with ice (even if it is not visible from the outside), the cold will not enter the chamber. This could be a problem with the defrost heating element, timer or control module. In such cases, simply adjusting the handle will not help - it requires repair and diagnostics by a specialist.
Why does ice freeze in the Atlant refrigerator with the correct settings?
Most often this is due to a loosely closed door or damage to the seal. The reason may also be the placement of hot products that release a lot of moisture, or a malfunction of the defrosting system (clogged drainage hole, burnt heating element). Check if anything is preventing the door from sealing tightly.
How often do you need to change the thermostat settings?
Under normal conditions, settings set once when installing the refrigerator do not require changes for months. Adjustment is only needed if there is a significant change in the temperature in the room (for example, turning off the heating in winter or abnormal heat in summer) or when the chamber is fully loaded with fresh food.
Is it possible to completely turn off the refrigerator if you go on vacation?
Yes, you can. But before this, the refrigerator must be defrosted, washed and dried, leaving the doors ajar. If you are leaving for a short time and want to preserve food, use the "Vacation" mode (if available) or simply set the minimum temperature, freeing the chamber from perishable food.
What to do if the electronic display shows an error?
If error symbols light up on the display (for example, flashing temperatures or codes), try unplugging the refrigerator for 10-15 minutes to reboot the system. If the error persists, write down the code and contact a service center, as this may indicate a problem with the sensors or control board.
Does the amount of food in the refrigerator affect the temperature setting?
Yes, a full refrigerator keeps the temperature more stable, since the food acts as cold accumulators. An empty refrigerator will have to be set a little “colder”, since every time the door is opened, cold air will be quickly replaced by warm air, and the compressor will have to work more often.
