Maintaining the correct microclimate inside the refrigeration unit is a key factor in ensuring long-term preservation of products and stable operation of the compressor. For Belarusian-made equipment Atlant this parameter is especially important, since these models are often equipped with mechanical regulators that require precise calibration by the user. An incorrectly set mode can lead to rapid deterioration of perishable goods or, conversely, to the freezing of vegetables and fruits that are not intended to be stored at negative values.
Owners are often faced with a situation where the indicators on the panel are on, but the products inside spoil faster than expected. This is a direct signal that temperature regime it has been violated. Unlike modern digital systems, where values are displayed in degrees Celsius, classic models Atlant use a scale from 1 to 7 or from MIN to MAX. Understanding the physics of the thermostat operation and the influence of external factors will help you avoid common operating errors.
Let us examine in detail what values are considered reference for different departments, how seasonal changes affect the operation of the motor and why you should not blindly trust the position of the regulator knob without checking with a real thermometer. Proper adjustment will extend the service life compressor and save energy.
Standard temperature standards for the refrigerator compartment
According to technical regulations and sanitary standards, the ideal temperature for the main compartment of the refrigerator should be in the range from +2 to +5 degrees Celsius. It is within these limits that most pathogenic bacteria slow down their vital activity, which allows products to remain fresh for a long time. For equipment Atlant with a system No Frost or drip defrosting, these indicators are the targets that the automation or the user strives for during manual settings.
However, it is worth considering that the distribution of cold inside the chamber is uneven. On the shelves located closer to the back wall and the source of cold (evaporator), the temperature is always lower than on the door or in the upper drawers. Therefore, the placement of products should be logical: meat and fish are stored in the coldest zones, and sauces and drinks are stored on the door, where the temperature is most stable, but slightly higher.
⚠️ Attention: If you set the regulator to maximum, and the products on the bottom shelf begin to become covered with ice, this indicates a malfunction of the thermostat or a refrigerant leak, and not a need to reduce power.
.+8 degrees is allowed only when loading a large amount of warm food or when doors are opened frequently. Constantly keeping food in areas above +6 degrees is dangerous to health. Below is a table of recommended modes for various groups of products stored in the main chamber:
| Product group | Optimal temperature (°C) | Shelf life (approximate) | Recommended zone |
|---|---|---|---|
| Fresh meat and fish | +1..+3 | 1-2 days | Bottom shelf, at the back wall |
| Dairy products | +2..+4 | 3-5 days | Middle shelves |
| Ready meals | +2..+5 | 2-3 days | Middle and top shelves |
| Vegetables and fruits | +4..+6 | 3-7 days | Bottom drawers (vegetables) |
| Eggs and sauces | +4..+8 | 7-14 days | Door shelves |
⚠️ Attention: Specifications may vary depending on the specific model and year of manufacture. Always check the official product data sheet to clarify the climate class of your equipment.
Deciphering the Atlant thermostat scale
Most refrigerator models Atlant, especially the KSh-268, KSh-350 series and their modifications, are equipped with a mechanical thermostat. On its handle are numbers from 1 to 7 (sometimes up to 8) or the designations MIN and MAX. Beginners are often puzzled by the question: what do these numbers mean and which position is correct? Simple logic works here: the number does not indicate degrees, but the work intensity compressor.
Position “1” or “MIN” means that the compressor will turn on rarely and work for a short time, maintaining minimum cooling capacity. In this mode, the temperature in the chamber will be closer to +7..+8°C. This is acceptable in winter in unheated rooms or when the refrigerator is almost empty. On the contrary, the “7” or “MAX” position forces the motor to work almost non-stop, trying to reach the lowest possible temperatures, down to -5..-8°C inside the main chamber, which will lead to freezing of products.
Why are there no exact degrees on the handle?
The mechanical thermostat reacts to changes in freon pressure in the capillary tube, and not to a direct temperature reading. The numbers are conventional divisions of the spring tension force inside the relay. The exact temperature value depends on the ambient temperature (temperature in the room), the fullness of the chamber and the tightness of the seals.
The golden mean for most everyday situations is the position of the knob on the number 3 or 4. This mode provides a balance between power consumption and cooling quality. If you notice that the food in the depths of the chamber begins to freeze, and a “fur coat” appears on the walls, you should switch the regulator to a division closer to MIN. If the milk turns sour within a day, and you feel stuffy inside, you need to add power by turning the knob towards MAX.
- 🌡️ Division 1-2: Economy mode, suitable for storing canned food or when the chamber load is low in winter.
- ❄️ Division 3-4: Standard operating mode for daily use by a family of 2-4 people.
- 🧊 Division 5-7: Intensive cooling mode, used for quick freezing of fresh food or in hot weather.
- 🛑 OFF position (0): Complete shutdown of the power supply to the compressor.
The influence of the model and defrosting system on the mode
When setting the temperature, you cannot ignore the design features of a particular model Atlant. The equipment is divided into two main types according to the defrosting system: with manual defrosting (static) and with the system No Frost (or Low Frost). The fundamental difference lies in air circulation and humidity, which directly affects the temperature perception of products.
In refrigerators with a drip system (crying wall), the cold comes from the back panel. It is important here not to press the products close to the back wall, otherwise they may freeze or, conversely, spoil due to lack of air circulation. In models No Frost cold air is pumped by a fan and distributed evenly throughout the entire volume. In such units, the temperature difference between the top and bottom shelves is minimal, but there is a higher risk of chairing products.
It is also worth considering the number of chambers and compressors. Two-compressor models Atlant allow you to independently adjust the temperature in the refrigerator and freezer compartments. This has the advantage that you can set the refrigerator to +4°C and the freezer to -18°C without fear of overloading the system. In single-compressor models, the adjustment is made by one regulator, which controls both compartments, which requires more careful control.
Seasonal adjustment of settings
The ambient air temperature in the room has a tremendous impact on the operation of refrigeration equipment. In the summer, when it can be +25..+28°C in the apartment, heat exchange in the condenser (the grill at the back of the refrigerator) is difficult. The compressor takes more time and effort to remove heat from the chamber. During this period, it is recommended to set the regulator closer to average values (3-4), but make sure that it does not overheat.
In winter the situation changes. If the refrigerator is located in an unheated kitchen or in a hallway where the temperature drops below +16°C, the oil in the compressor may thicken and the thermostat will no longer give a signal to turn on. As a result, the camera will defrost. For the winter period, if the temperature in the room is below +18°C, experts advise not to use modes below 2-3 divisions, so as not to create excess pressure in the system.
⚠️ Attention: Installing the refrigerator next to heat sources (radiators, ovens) or under direct sunlight makes it impossible to maintain the correct temperature even at maximum settings regulator.
The change of seasons is the ideal time to revise the settings. The transition from winter to summer mode should be accompanied by checking the tightness of the door and cleaning the condenser from dust. These are simple steps that will help the cooling system work efficiently without putting extra strain on the electrical network.
How to check the real temperature inside
You cannot trust only the sensations (“it seems cold”) or the position of the thermostat knob. Mechanical controls wear out over time, and the number “3” on the old knob may no longer correspond to the actual +4°C. The only reliable way to find out what temperature is in your Atlanta is to use an external measuring device.
A regular household water thermometer or a special thermometer for refrigerators is ideal for this purpose. Carry out an experiment: pour water into a glass, place a thermometer in it and place the glass on the middle shelf of a working refrigerator. Leave for 2-3 hours without opening the door. After this, quickly open the door and take readings. This will give you an objective picture.
☑️ Checking the temperature
If the readings differ from the norm (+2..+5°C), adjust the position of the thermostat knob. Shift it by one division and repeat the measurement procedure every other day. You should not turn the knob sharply to several positions at once, since the system requires time (up to 24 hours) to stabilize heat balance.
Common problems and their solutions
Even with correct settings, users may encounter anomalies. For example, the refrigerator compartment is too cold and the food is covered with frost. Often the reason lies not in a breakdown, but in the fact that the air duct damper (if the model has one) is stuck in the open position, or the thermostat is “stuck.” In such cases, careful defrosting of the refrigerator during the day with the power turned off helps.
The other extreme is that the refrigerator runs continuously, hums, but the temperature does not drop below +10..+12°C. This may indicate a freon leak or loss of compressor performance. Another common cause is a leak in the door seal. Check the integrity of the seal: clamp a sheet of paper between the door and the body and try to pull it out. If the paper is pulled out without effort, the seal requires replacement or adjustment.
- 🔧Thermostat malfunction: The refrigerator does not turn on or off. The sensor needs to be replaced.
* 🌬️Clogged capillary tube: The compressor is running, but there is no cold. The system needs to be cleaned by a technician.
* 🚪The door is not tightly closed: The entry of warm air causes constant operation of the motor. Check the load on the shelves.
Why does ice freeze in the Atlant refrigerator, although the temperature is set correctly?
The formation of ice (coat) with the correct thermometer readings most often indicates that you leave the door open for too long or foods with a high moisture content without packaging get into the chamber. It is also possible that the tightness of the seal is broken, and moist air from the room constantly penetrates inside, condensing on the cold walls. In No Frost models, the cause may be a malfunction of the defrosting system (heating element or timer).
Is it possible to store watermelon in the Atlant refrigerator and at what temperature?
Yes, you can, but not for long. The optimal temperature for storing cut watermelon is +2..+3°C. It is better to store a whole watermelon at a temperature of +1..+3°C, but no more than 1-2 days, since at lower temperatures the pulp may lose its taste and become flabby. It is recommended to wrap the cut watermelon in cling film.
What to do if the temperature is not restored after defrosting?
After complete defrosting, the refrigerator takes time to return to operating mode. For models Atlant this time ranges from 4 to 8 hours (up to 24 hours for the first start). During this period, do not completely load the chamber with food and do not open the door unless necessary. If after 24 hours the temperature has not dropped to normal, check the position of the regulator and the integrity of the seals.
Does the amount of food in the chamber affect the temperature?
Yes, it does significantly. An empty refrigerator cools down faster, but also heats up faster when the door is opened. A full chamber holds cold better (products act as cold accumulators), but to initially cool a large volume of warm products, the compressor will have to work in increased mode. It is recommended to fill the chamber gradually.
