Correct setting of the temperature regime in a two-chamber refrigerator Atlant is the foundation for long-term storage of products and preservation of their taste. Many equipment owners are faced with a situation where the freezer is not cold enough or, conversely, food freezes and loses moisture. In such cases, it is necessary to correctly adjust the thermostat, taking into account the model of your device and operating conditions.
Modern and classic models of the Belarusian brand can differ significantly in the type of control. Somewhere a time-tested mechanical thermostat with a rotary knob is used, and somewhere an advanced electronic system with a digital display is used. Understanding the operating principle of your particular unit will allow you to avoid mistakes that can lead to damage to the compressor or defrosting of supplies.
In this article we will analyze in detail the setting algorithms for various series, explain the physical meaning of the regulator positions and answer frequently asked questions. You will learn to determine the optimal parameters for freezing meat, vegetables and semi-finished products, and also learn how external factors affect the operation of the refrigeration circuit.
Principles of operation of the Atlant cooling system
Fundamentally, the cooling process in two-chamber models Atlant is based on refrigerant circulation and operation compressor, which is controlled by a temperature sensor. In classic models, this sensor is a thermostat that responds to changes in thermal conditions in the evaporator or directly in the chamber. When the temperature rises above a predetermined threshold, the contacts close, starting the motor.
It is important to understand that in systems with one compressor (which is typical for most brand models), the temperature in the refrigerator compartment and freezer are interconnected. By adjusting the cooling power, you influence both circuits, although priority is often given to the freezer. Thermoregulator in such systems it does not measure temperature directly with high accuracy, but reacts to the degree of cooling of the sensing element.
⚠️ Attention: In models with a system No Frost or "Crying evaporator" the principle of turning off the compressor may differ. Here, the sensor is often installed on the evaporator, hidden behind the rear wall, so the response to changes in the chamber occurs with a delay.
Electronic control, found in more expensive series, uses separate temperature sensors for each zone. This allows the system to independently regulate the operation of the fans and dampers that supply cold air. In such units, the freezer temperature is adjusted with an accuracy of a degree through the control panel on the door.
Determining the type of control of your model
Before you start setting up, you need to accurately identify the type of control of your refrigerator. The actions you have to take depend on this. A visual inspection of the front panel or interior of the chamber will provide comprehensive information about what kind of mechanism you are dealing with.
Mechanical controls are characterized by the presence of a rotary handle, usually located inside the refrigerator compartment (often in the upper right corner) or on the top of the case. The scale of this handle has numbers from 1 to 7 or from Min to Max. These numbers do not indicate degrees Celsius, but indicate the intensity of the compressor.
Electronic control is easily recognized by the presence of an LED display or a series of buttons on the outside of the door. The screen displays the current temperature readings. In such models, adjustment is made by pressing buttons with arrows or snowflake symbols, which allows you to set specific numerical values.
There are also combined options, where the main control is mechanical, but there are additional functions, such as “Super Freeze”, activated by a separate button. In this case, the basic setting is made using the handle, and the accelerated cooling mode is turned on temporarily as needed.
Setting the mechanical thermostat
If your refrigerator Atlant has a mechanical handle installed, the process of adjusting the temperature of the freezer requires an understanding of the logic of the thermostat. The numbers on the scale indicate the tension force of the spring inside the sensor, which determines at what temperature the electrical circuit will break and the compressor will stop.
The higher the number to which you set the pointer, the the temperature will be lower in the freezer compartment. Setting the knob to the "7" or "Max" position causes the compressor to run almost non-stop until the evaporator is covered in a thick layer of ice and cools to extreme temperatures. This can lead to icing of the products.
The optimal position for everyday use is considered to be "3" or "4". In this mode, the compressor operates cyclically, managing to reach the desired temperature and rest. This ensures a balance between high-quality freezing and energy consumption, and also extends the life of the engine.
☑️ Algorithm for setting the mechanics
It is worth noting that position "1" or "Min" means minimal cooling. In this mode, the compressor will rarely turn on, and the temperature in the freezer may rise above what is safe for long-term storage (above -12°C). Use such settings only in very hot rooms or when the chambers are minimally loaded.
Temperature control in electronic models
Owners of electronically controlled refrigerators are luckier: they can set the exact temperature in degrees Celsius. To enter the setting mode, you usually need to press and hold the snowflake or thermometer button for 3-5 seconds until the numbers on the display begin to flash.
Use the Up and Down arrow buttons to set the desired value. For the freezer, the standard range is -16°C to -18°C. After selecting a value, you must confirm the setting, usually by pressing the setting button again or simply stopping for a few seconds so that the system saves the parameters.
Electronics allows you to implement the function Super freezing (Super Freeze). When this mode is activated (the corresponding indicator lights up), the refrigerator ignores the standard settings and operates at maximum power, lowering the temperature to -24°C and below. This is useful when loading a large volume of fresh products.
| Operating mode | Temperature (approximate) | Influence on the compressor | Recommendation |
|---|---|---|---|
| Economy / Min | -12°C... -14°C | Rare inclusions | For light load |
| Normal (Standard) | -18°C | Cyclic operation | Daily use |
| Max / Max | -20°C... -24°C | Continuous work | Stocking supplies |
| Super freezing | up to -26°C | Continuous operation | Only when loading |
⚠️ Attention: Do not leave the “Super Freeze” mode on for longer than 24-48 hours. Long-term operation of the engine at its maximum without interruption can lead to its overheating and failure.
Factors affecting the temperature in the chamber
Even correctly set settings may not give the expected result if external factors are not taken into account. Ambient temperature plays a critical role. If the refrigerator is in the kitchen, where it is hot (+28°C and above), or next to a heating radiator, the cooling system has to work under increased load.
The loading density of the chambers also affects thermodynamics. An empty refrigerator cools down faster, but also loses cold instantly when the door is opened. A chamber filled with products (especially if these are frozen semi-finished products) works as a cold accumulator, smoothing out temperature changes. However, if you fill the freezer to capacity, air circulation will be disrupted.
The technical condition of the door seals is another important aspect. If the elastic does not fit tightly, warm, moist air constantly enters the chamber. The compressor will try to compensate for the heat by working non-stop, but it will never reach the desired temperature in the freezer. In this case, adjusting the thermostat is useless.
Why is there ice in the freezer, but the food is melting?
This is a classic sign of air circulation problems or freon leaks. If the evaporator is overgrown with a fur coat, the cold does not enter the chamber. Defrosting or repair is required.
The frequency of door openings directly correlates with the loss of cold. Each opening triggers a convection exchange: heavy cold air flows out, and light warm air flows in. In the summer, this effect intensifies, which may require a temporary increase in the cooling mode.
Diagnostics and elimination (Common problems)
There are situations when adjusting the temperature does not help. If you turn the knob to maximum, but the freezer is still warm, or vice versa - everything turns into an icy monolith even at minimum, the problem may lie in a component failure. The first step is to exclude banal defrosting.
If the refrigerator runs continuously 24 hours a day, hums, but does not freeze properly, there may be a refrigerant leak or a clogged capillary tube. In such cases thermostat regularly gives the command to cool, but physically the system cannot remove heat. A call to the technician is required.
If the refrigerator turns off too often (short operating cycle) and the food in the freezer thaws, the thermostat may be stuck or lost sensitivity. He prematurely (prematurely) turns off the compressor, “thinking” that the cold has already been gained. Replacing the thermostat usually solves this problem.
Sometimes users are faced with a situation where it is warm in the refrigerator compartment, but "Antarctica" in the freezer. In single-circuit systems, this is often treated by adjusting the damper (if there is one) or simply reducing the overall cooling power, since priority is always given to the freezer.
How often do you need to defrost the Atlant refrigerator?
Models with manual defrosting require disconnecting from the network at least 2 times a year. The No Frost and “Crying Evaporator” systems in the refrigeration chamber do not require manual defrosting, but preventative washing and shutdown once a year for hygiene will not hurt.
Is it possible to set the temperature to -30 degrees?
In Atlant household models, such a temperature is not provided and is not needed. The deep-frozen standard is -18°C. Lower temperatures are required only for specific industrial tasks and will lead to excessive energy consumption.
Why, after setting the temperature, does it not change immediately?
The refrigerator is an inertial system. After changing the thermostat position or electronic settings, 4 to 8 hours (sometimes up to a day) must pass for the temperature regime to completely stabilize and the new values to be recorded.
What to do if the thermostat handle is jammed?
Do not use excessive force so as not to break the plastic rod. Try gently rocking the handle. If it does not give in, condensation may have gotten inside and frozen, or the mechanism may be damaged. In this case, the unit needs to be replaced.
