The situation when products in the refrigerator compartment begin to freezing, and the milk turns into an ice block, is familiar to many owners of household appliances. Most often, this indicates that temperature conditions it is set too aggressively for the current operating conditions. In refrigerators of the Belarusian brand Atlant the control system may differ depending on the model, be it a classic mechanical regulator or a modern electronic panel.
Before calling a technician or looking for faults in the defrosting system, you need to check the settings. Raising the temperature isn't just a matter of turning a knob, it's a delicate balancing act between food preservation and energy consumption. In this article, we will analyze action algorithms for various modifications of units Atlantso that you can quickly adjust the operation of the device.
Incorrect operation thermostat or a failure in the electronic unit can lead to the compressor working almost without stopping. This not only increases energy consumption, but also reduces the life of the motor. Understanding the operating principles of your model will help you avoid unnecessary costs and damage to products.
Features of temperature control in different Atlant models
Refrigerators Atlant are divided into two main groups according to the type of control: mechanical and electronic. In mechanical models, which make up the majority of the equipment fleet, adjustment is carried out using a rotary control located inside the chamber or on the body. There is no digital display of degrees, but a scale from 1 to 7 (or from Min to Max), where each division corresponds to a certain temperature range.
In more modern models with a system No Frost or electronic control (XM, CM series with display), the process looks different. Here the user sees the exact values on the display, and the parameters are changed through touch buttons or mechanical keys on the front panel of the door. It is important to understand that in two-chamber models with one compressor, an increase in temperature in the refrigerator compartment indirectly affects the freezer compartment, since the refrigerant circulates through a single circuit.
⚠️ Attention: In models with electronic control, changes do not take effect instantly. The system requires from 10 to 30 minutes to stabilize the compressor after your intervention.
Particular attention should be paid to models with a freshness zone. In them, temperature zones can be adjusted independently, and a change in the general mode may not affect the special compartment for vegetables. Always check the product data sheet, since the logic of operation may differ for different years of manufacture. electronic module may differ for different years of manufacture.
Setting a mechanical thermostat
If your refrigerator is equipped with a round knob with numbers inside the chamber, you are dealing with classic thermostat. The principle of its operation is simple: the contacts close and open when a certain temperature of the sensitive element is reached. To increase the temperature (make the mode warmer), you need to turn the knob towards lower values. For example, if the regulator was at position “5”, move it to “3” or “2”.
The numbers on the scale do not indicate degrees Celsius. They indicate the intensity of the compressor. One is the minimum cooling (highest temperature inside), and seven or Max is the maximum freezing. When you turn the knob towards decreasing numbers, you increase the period of time during which the compressor rests, allowing the temperature in the chamber to rise.
The adjustment process requires patience. Once you have changed the position of the pen, do not expect instant results. The air in the chamber should warm up, and the thermostat should record new readings. Stabilization usually takes several hours. If after a day the products are still freezing, the procedure can be repeated, moving the regulator one more notch towards heat.
☑️ Algorithm for setting the mechanics
It is worth noting that mechanical thermostats may lose calibration over time. If the knob is set to minimum (1) and the food still freezes, the bellows itself may have failed or the bellows seal has broken. In such cases, replacement of the thermostat is required, since further adjustment will be ineffective. capillary sensor or the seal of the bellows is broken. In such cases, the thermostat needs to be replaced, as further adjustment will be ineffective.
Temperature adjustment in models with electronic control
Owners of refrigerators Atlant with a display on the door are more fortunate in terms of control, but there are some problems here too nuances. Control is carried out through a panel that displays the current temperature in the refrigerator and freezer compartments. To increase the temperature in the main chamber, you need to find a button indicating the refrigerator compartment (often this is a snowflake symbol or the inscription Fridge) and press it until the desired value appears on the display.
The standard value for storing most products is considered to be a range from +3 to +5 degrees Celsius. If you have it set to +1 or +2, food on the top shelves may freeze. Increase the value to +4 or +5. In some models, to activate the setting mode, you need to hold the button for 3-5 seconds, after which the numbers will begin to flash, signaling that you are ready to enter new parameters.
Electronics allows you to set the exact mode, but it is also more sensitive to power surges. If, after turning off the light, the settings are reset to the factory settings (usually maximum cold), they will have to be set again manually. Also, such models often have a “Super Freeze” or “Super Cool” function, which forcibly keeps the temperature low. Make sure this mode is disabled if you want to increase the temperature.
⚠️ Warning: Do not attempt to change settings if the panel is locked. Many models have a child protection function (Lock), which is activated by a long press on the corresponding button.
Therefore, the readings on the display may differ slightly from the actual temperature on the shelf measured with a household thermometer. An error of 1-2 degrees is allowed.
What to do if the buttons do not respond?
If the touch panel does not respond to touch, it may be blocked or dirty. Wipe the panel with a soft, dry cloth. If there is a lock (the lock icon is lit), hold down the Lock button for 3-5 seconds until the beep sounds. In rare cases, it is necessary to reboot the refrigerator from the network.
The influence of external factors on the temperature regime
Sometimes the problem lies not in the settings, but in the operating conditions. A refrigerator Atlant, like any other, works in conjunction with the environment. If you install the unit next to a radiator, gas stove, or in direct sunlight, the cooling system has to work at its limit. In such conditions, even with minimal thermostat settings, the temperature inside can be unstable, although more often the opposite effect is observed - insufficient cold.
However, if the refrigerator is in an unheated room in winter or near a window where the temperature drops below +10 degrees, this may disrupt the operation of the thermostat. The mechanical regulator may “think” that the chamber is already cold enough and not turn on the compressor, or, conversely, due to a violation of the viscosity of the oil and refrigerant, it may not work correctly. For normal operation, the refrigerator requires an ambient temperature in the range from +10 to +32 degrees (climate class N, SN).
Load density also plays a role. An empty refrigerator reacts faster to changes, but holds the cold worse when the door is opened. An overloaded unit, where products block the air ducts (in No Frost) or are pressed tightly against the back wall (in drip) will exhibit uneven temperature distribution. In areas of direct contact with the rear wall, food may freeze, even if the thermostat is set correctly.
The frequency of door openings is another critical factor. If the door is slammed every five minutes, or it remains open for a long time during cooking, the compressor does not have time to compensate for the heat gain. In an attempt to achieve the set temperature, it can work continuously, causing food to freeze at the back wall.
Table of correspondence between settings and temperature conditions
For ease of understanding the relationship between the position of the regulator and the actual temperature inside the chamber, we present average data. It is worth considering that actual indicators depend on the load, the temperature in the room and the technical condition of a particular instance.
| Regulator position | Expected temperature (°C) | Compressor operating mode | Recommendation |
|---|---|---|---|
| 1 (Min) | +7.. +9 | Short-term | Summer or for products that do not require extreme cold |
| 3 (Average) | +4.. +5 | Normal | Standard mode for everyday storage |
| 5 (Max) | +1.. +2 | Long-term | For quick freezing of fresh food or hot summer |
| 7 (Frozen) | 0.. -1 | Permanent | Not recommended for continuous use (risk of icing) |
The table shows that to increase the temperature it is necessary to shift the regulator towards lower values. However, you should not fall below one, since in the zone of +8..+9 degrees bacteria begin to multiply more actively, which shortens the shelf life of perishable foods.
Diagnosis of faults when adjustment is impossible
There are times when the user turns the knob or changes the numbers on the display, but the temperature does not change. Food continues to freeze, and the compressor hums without interruption. This is a sure sign of a technical malfunction. The most likely reason is sticking of the thermostat contacts or failure thermal sensor. In mechanical models, the contacts can simply “weld” to each other due to sparking, and the circuit will never break.
In refrigerators with the No Frost system, the cause may be a malfunction of the defrost sensor or the evaporator heating element. If the evaporator becomes covered with a “coat” of ice, the airflow is blocked. Cold air does not circulate normally, the sensor in the upper part of the chamber does not sense the cold and does not give a command to stop the compressor, although in reality there is already sub-zero temperature.
It is also worth checking the rubber seals on the doors. If they do not fit tightly, warm, moist air constantly enters the chamber. The compressor tries to cool this flow, working hard. This may not be noticeable visually, but the rubber band may be sticky or deformed to the touch.
⚠️ Attention: If you hear clicks of the thermostat, but the compressor does not turn off for hours, and the temperature inside is below 0 degrees, immediately unplug the device to avoid defrosting the products and contact service.
Placement rules products for optimal cold
Proper organization of space inside the refrigerator Atlant helps maintain a stable temperature without extreme settings. Cold air is heavier than warm air, so it sinks. In drip systems, the back wall is the coldest zone. This is where you should not store vegetables that are afraid of freezing (cucumbers, herbs, tomatoes).
To store such products, it is better to use bottom drawers or special freshness zones, if they are provided for by the design. It is better to place dairy products and ready-made food on the middle shelves, where the temperature regime is most stable. Door shelves are the warmest place, suitable for sauces, drinks and eggs, but not for milk or meat.
Do not place hot foods inside. This causes a sharp jump in temperature and humidity, forcing the compressor to work in emergency mode. Wait for the food to cool to room temperature. Also, do not overcrowd the refrigerator: air should circulate freely around the products, especially in models with No Frost.
Why does ice freeze on the back wall in the Atlant refrigerator?
Ice formation on the back wall of refrigerators with a drip system is part of the normal defrost cycle. The water flows into the groove and evaporates. However, if the ice turns into a snowdrift, it means that the outflow of water is impaired (the drainage hole is clogged) or the thermostat is faulty, which does not allow the chamber to warm up for defrosting.
Is it possible to increase the temperature in the freezer separately?
In single-compressor models (most Atlant), it is impossible to separately regulate the temperature in the freezer. By changing the settings in the refrigerator compartment, you affect the overall circuit. In two-compressor models (the index often contains the number 2, for example, 1702-..) the compartments are independent, and the temperature in the freezer can be changed separately through its own regulator.
How often do you need to defrost the Atlant refrigerator?
Models with manual defrosting require clearing of ice when its layer reaches 5-10 mm (about once every 3-6 months). Drip defrost systems (weeping wall) do not require defrosting more than once a year for hygiene. The No Frost system does not require defrosting, but preventive shutdown once a year for washing is recommended.
Does the amount of food affect the temperature?
Yes, it does. A full refrigerator holds cold better when the door is briefly opened, since the food acts as cold accumulators. However, if there are too many products and they block the air supply channels, the temperature will be distributed unevenly and the thermostat will not work correctly.
