The situation when food in the refrigerator compartment begins to freeze and an ice crust forms in the freezer is familiar to many owners of household appliances. Two-chamber models of the Belarusian brand Atlant are famous for their reliability, but require proper handling of the thermostat to ensure optimal storage conditions. An incorrectly set compressor operating mode often causes damage to supplies or increased energy consumption.
Before proceeding with mechanical adjustment, you need to understand that temperature conditions depends not only on the position of the handle, but also on the loading of the chambers, the tightness of the seals and even the temperature in the room. In this article, we will analyze all the nuances of setting that are typical for various series of equipment and will help you avoid typical mistakes that can lead to breakdown of the unit.
Understanding the operating principle of your device is the key to its long service. We will look in detail at the difference between mechanical and electronic control systems, since the approach to them is radically different. We will also pay attention to the peculiarities of work in the winter, when operating conditions change.
Determining the type of control system
The first step towards proper setup is identifying the control system of your refrigerator. Models Atlant can be equipped with both classic mechanical thermostats and modern electronic units. The algorithm of your actions directly depends on this.
In mechanical models you will see inside the refrigerator compartment (usually at the top right or on the top wall) a round handle with divisions from 1 to 7 or from Min to Max. This is thermostat, which physically opens the electrical circuit when a certain temperature is reached. There are no exact degrees here, only conditional cold zones.
Electronic control systems are usually located on the outer door or in the upper part of the case. They are equipped digital displaywhere the temperature is displayed in degrees Celsius. Such systems allow you to set precise values and often have “Holiday”, “Super Freeze” or “Eco” modes.
⚠️ Attention: In models with electronic control, changing settings is often blocked after a few seconds of inactivity. If you did not have time to press the confirmation button, the system will have to be unlocked again by holding down the corresponding key.
It is important not to confuse the refrigerator temperature regulator with the freezer power regulator, if any. In some older models Atlant the freezer control is also located outside or is located inside it separately.
Setting a mechanical thermostat
If your refrigerator has a mechanical handle, the adjustment process requires patience and an understanding of the physics of the process. Turning the knob counterclockwise towards lower values (or towards Min) reduces the temperature, causing the compressor to turn on less often.
However, do not make sudden movements. The mechanics are inertial: after turning the handle, the compressor will take from 30 minutes to 2 hours to reach a new operating mode. If you immediately turn the knob to minimum, the food may not have time to cool, and you will mistakenly decide that the equipment is faulty.
☑️ Algorithm for setting the mechanics
The optimal position for year-round operation is considered to be the average value of the scale. For most models Atlant this is division 3 or 4 on a seven-step scale. In winter, when the room is cool, you can reduce the power a little (turn towards Min), and in summer you can add it.
There is a common misconception that the number on the regulator corresponds to the temperature in degrees. This is wrong. The number indicates the cooling intensity. The larger the number, the lower temperature there is inside the chamber. Therefore, to make it “warmer”, we turn towards lower numbers.
⚠️ Attention: Never try to remove the thermostat knob by force if it is stuck. The plastic on older models becomes brittle and can crack, which will require replacing the entire control unit.
Adjusting the electronic control
Owners of models with a display are more fortunate: here you can set the exact temperature, for example +4°C for the refrigerator compartment and -18°C for the freezer. To change parameters, you usually need to press and hold the button with the image of a thermometer or snowflake for 3-5 seconds.
After entering the setting mode, the values begin to flash. Using the arrow buttons + and -, set the desired value. To save the setting, simply stop pressing the buttons - after a few seconds the system will record the selection automatically. Some models require confirmation with a button OK or Enter.
What is Super Freeze mode?
The Super Freeze mode forces the compressor to operate continuously, ignoring sensor readings. It cannot be used for permanent storage of food, as this will lead to freezing and increased electricity bills.
Electronics are sensitive to power surges. If after turning off the light the settings are lost, most likely the battery in the device’s memory is dead or the controller has been reset. In this case parameters you will have to set it again manually.
Some advanced models Atlant allow you to independently adjust the temperature in different zones, if there are several of them. This is useful when you need to quickly cool drinks in one zone without freezing vegetables in another.
Optimal temperature values
Knowing the correct values will help not only preserve food, but also extend the life of the compressor. Manufacturers recommend maintaining the temperature in the refrigerator compartment in the range from +2°C to +6°C. In the freezer, the optimal value is -18°C and below.
Why exactly these numbers? At higher temperatures +6°C bacteria begin to actively multiply and food spoils faster. At temperatures below +2°C vegetables and fruits can lose moisture, wither or even freeze at the walls.
The temperature in the freezer -18°C guarantees that meat, fish and other products will retain their properties for up to 12 months. Lower values (for example, -24°C) are needed only for quick freezing of fresh products, but constantly maintaining this mode is not economically profitable.
| Product type | Recommended zone | Optimal temperature | Shelf life (approx.) |
|---|---|---|---|
| Meat and fish (chilled) | Bottom shelf / Zero zone | 0°C ... +2°C |
1-3 days |
| Dairy products | Middle shelves | +2°C ... +4°C |
3-7 days |
| Vegetables and fruits | Drawers below | +4°C ... +8°C |
3-10 days |
| Ready meals | Top shelves | +3°C ... +5°C |
1-2 days |
The influence of loading and placement of products
Often users complain about uneven cold, not suspecting that the problem lies in improper loading. Cold air in two-chamber Atlanta circulates naturally or using the system No Frost. If you block the ventilation holes with food, the cold will not reach the far corners.
Leave a gap of 2-3 centimeters between the back wall of the chamber and the products. This will ensure free circulation of air flow. The tight “packing” of the chamber leads to the fact that the temperature sensor located near the wall considers that the cold has already set in and turns off the compressor while the food in the center of the chamber is still warm.
It is absolutely forbidden to put hot foods in the refrigerator. This will not only increase the overall temperature inside, causing the compressor to work harder, but will also create condensation that will turn into ice. Allow the food to cool to room temperature before storing.
If you have just placed a large amount of room temperature food in the chamber, it makes sense to temporarily turn on the intensive cooling mode (if it has one) or temporarily turn the mechanical control to stronger cooling, and after a day return it back.
Seasonal characteristics and external factors
The room temperature directly affects the operation of the refrigerator. In the summer, when the kitchen +25°C or higher, the refrigerator Atlant requires more time and energy to remove heat. During such periods, a slight adjustment of the regulator towards lower temperatures (large number) may be required.
In winter the situation is the opposite. If the refrigerator is in an unheated hallway or in the kitchen with an open window, where the temperature drops below +16°C, the compressor may not turn on at all. In mechanical models, this is solved by installing a special winter kit or heating the thermostat zone, but it is easier to move the unit to heat.
Direct sunlight falling on the body, or proximity to the stove/battery are the enemies of proper thermoregulation. Heating the case from the outside makes the sensors “think” that it’s hot inside, and the refrigerator works without interruption, freezing food.
⚠️ Attention: Installing the refrigerator closer than 10 cm from the wall or heating devices disrupts the heat exchange of the condenser (grid at the back), which leads to overheating of the compressor and incorrect temperature maintenance.
Diagnostics of temperature problems
If you lower the temperature according to the instructions, but the food still freezes or, conversely, spoils, it may not be the settings. Check the door for tightness. A sheet of paper sandwiched between the door and the body must be removed with force. If it falls out freely, seal requires replacement or wiping.
Icing on the back wall of the refrigerator compartment (in models with a drip system) is normal. The ice should flow into the groove when the compressor is turned off. If all products and shelves are covered with ice, the defrost sensor may be faulty or the thermostat is “stuck” in the extreme cold position.
Extraneous noise, humming or complete absence of sound from a running compressor in warm chambers are signs of a technical malfunction. In such cases, adjusting the knobs is pointless; you need to call a technician to diagnose the refrigerant or electronics.
Regular defrosting (for models with manual defrosting) also affects the temperature regime. A thick layer of ice on the evaporator acts as a heat insulator, interfering with cooling. A layer of ice of more than 5 mm already significantly reduces operating efficiency.
Frequently asked questions
Why does the temperature not change immediately after adjusting the knob?
A temperature regulator is a mechanical or electronic device with a certain inertia. The refrigerant in the system needs time to redistribute and change the temperature of the evaporator. Typically, stabilization takes from 1 to 3 hours, depending on the load of the chambers.
Is it possible to keep the refrigerator constantly at maximum cold (7 or Max)?
This is not recommended. The maximum power mode is designed for quick freezing or cooling of large quantities of food. Constant operation at the limit leads to accelerated wear of the compressor, excessive consumption of electricity and the risk of defrosting food during any short-term blackout.
What to do if the refrigerator compartment is +10°C, and the regulator is already at a minimum?
If the knob is turned to the minimum cold (highest number), and the temperature is still high, There may be a freon leak, a malfunction of the thermostat or compressor. You need to defrost the refrigerator (at least 24 hours) and check if it works. If not, repair is needed.
Does the color of the Atlant refrigerator body affect the temperature inside?
No, the color of the external enamel does not affect thermal insulation. However, dark colors heat up more in the sun, which can indirectly increase the load on the cooling system if the refrigerator is in a lighted place.
How to understand that the thermostat is faulty?
Main signs: the compressor either does not turn on at all, or works non-stop, not turning off even at a clearly low temperature inside. Another sign may be the absence of a click when turning the mechanical regulator knob (although some modern models operate silently).
