Modern two-chamber refrigerators, especially popular models of the Belarusian brand Atlant, are often perceived by users as monolithic systems that work exclusively in conjunction. However, in situations where defrosting, temporary storage of food only at above-zero temperatures, or energy saving is required, a reasonable question arises about the possibility of isolated operation of the refrigeration compartment. Understanding the principles of operation of the compressor and the refrigerant distribution system is the key to competent management of household appliances.
Many owners mistakenly believe that to stop freezing it is necessary to completely unplug the appliance, which is categorically unacceptable when it is necessary to preserve food freshness in the main chamber. In fact, the design of many models Atlant provides for various adjustment mechanisms that allow minimizing the refrigeration capacity in the freezer compartment or stopping it completely, while maintaining the operation of the main circuit. It is important to distinguish between mechanical and electronic control systems, since the algorithm of actions for them will be radically different.
In this article we will analyze in detail the technical nuances that allow you to achieve the desired result without the risk of damaging expensive equipment. We will look at the features of thermostats, the functions of the “Vacation” mode and specific combinations of buttons for different series of refrigerators. Completely stopping the operation of the evaporator in the freezer while the compressor is running is physically impossible in models with one compressor without the use of special modes or external timers. Therefore, it is important to understand that “turning off” most often means switching to the minimum load or defrosting mode.
⚠️ Attention: Before any manipulations with the settings, make sure that there are no products in the freezer that require deep freezing, as the temperature in the compartment will begin to rise rapidly.
The principle of operation of Atlant two-chamber systems
To effectively manage temperature modes, it is necessary to understand the basic physics of the process. Most two-chamber refrigerators Atlant use one compressor, which pumps refrigerant into both evaporator circuits at once. The system is designed so that freon first passes through the evaporator of the freezer, where it boils at very low temperatures, and then, already heated, enters the evaporator of the refrigeration compartment.
This sequence means that freezer compartment is always the priority cooling zone. A thermostat or electronic sensor most often reads the temperature in the freezer or evaporator area. Until the set low temperature is reached there, the compressor will not receive a signal to stop, and cold air will continue to circulate, affecting the upper compartment.
- ❄️ The refrigerant moves in a closed circuit, cooling first the lower, then the upper compartment.
- ⚙️ The compressor stops only after reaching target values in the priority zone (usually the freezer).
- 🌡️ Power adjustment affects the operating time of the compressor, but does not completely turn off the cold supply to one of the compartments.
There are models with the system No Frost and a drip defrosting system, where air distribution is forced through fans. In such systems, it is even more difficult to isolate the freezer, since air flows can mix through special channels. Understanding this architecture helps to avoid futile attempts to “block” the cold by simply adjusting the handles, if the model does not structurally provide for this.
Mechanical control: working with a thermostat
In refrigerators Atlant with mechanical control, adjustment is carried out using a thermostat, which is usually a rotary knob with digital markings or a scale from Min to Max. This device is located inside the fridge compartment, less often - on the outside of the housing. It is he who is responsible for turning the compressor on and off depending on the temperature in the chamber.
In order to minimize the intensity of freezing in the lower chamber, you need to turn the thermostat knob to position Min or to number 1. In this mode, the thermostat will allow the temperature in the chamber to rise to the maximum allowable value before starting the compressor. This will lead to short engine operation cycles and long pauses.
☑️ Setting up a mechanical thermostat
It is worth noting that even in the minimum position The compressor will turn on periodically to maintain a low temperature in the freezer. If your goal is to completely defrost the lower chamber while the upper compartment is running, a mechanical regulator will not allow you to do this in isolation. You will have to resort to completely turning off the device or using the forced defrosting mode, if it is provided for by the design.
⚠️ Attention: Do not try to forcefully remove the thermostat handle or disassemble its mechanism. This will lead to a violation of calibration and incorrect operation of the refrigerator in the future.
Electronic control and “Vacation” mode
More modern models Atlant are equipped with an electronic control unit with a digital display. Here the customization options are much wider. The user can set the exact temperature for each compartment independently if the model supports dual-circuit control or has dampers. However, even in such systems, complete shutdown of one circuit while the other is working is rare.
The function known as the "Vacation" (Vacation) mode deserves special attention. This mode is specially designed for situations when the owners leave for a long time. Its main task is to minimize energy consumption and prevent the appearance of mold and unpleasant odors in an empty refrigerator.
When the "Vacation" mode is activated, the following processes occur:
- 🏠 The temperature in the refrigerator compartment is set at +15°C, which prevents empty shelves and saves energy.
- 🧊 The freezer continues to operate normally, keeping food frozen.
- 🔌 The light inside the chambers goes out, and the control panel can go into sleep mode.
Unfortunately, there is no inverse mode, which would turn off the freezer and leave the refrigerator compartment working, there is no “Vacation” in the standard functionality. To implement this task, owners of electronics have to look for workarounds, for example, using external timers or manual control, if the model allows you to set the freezer temperature above 0°C, which technically turns it into a second refrigeration compartment, but this is not possible in all modifications.
What happens to the compressor in the “Vacation” mode?
The compressor turns on extremely rarely, so how to maintain a temperature of +15°C in a well-insulated refrigerator box is very easy. This significantly extends the life of the engine.
Using the quick freezing and defrosting function
Some refrigerator models Atlant are equipped with accelerated cooling or defrosting functions. The Super Freeze button causes the compressor to run continuously for several hours, ignoring the thermostat readings. The opposite effect - “Super defrosting” for a separate chamber - is usually not provided in household models.
Nevertheless, knowledge of the system’s operating cycles is important. If you forcefully defrost your freezer (by turning the refrigerator off completely), it is important to restart it properly. After defrosting and turning on, it is recommended to activate the maximum freezing mode for 2-3 hours to quickly increase the temperature, and then return the regulator to the normal position.
In models with electronics, it is sometimes possible to temporarily disable the alarm or certain zones, but this is rather an exception. The main method of influencing the cycle is to set the target temperature. If you set the freezer temperature to -6°C instead of the standard -18°C, it will operate in gentle mode, consuming less electricity.
| Parameter | Standard mode | Vacation mode | Min mode (Mechanics) |
|---|---|---|---|
| Refrigeration chamber temperature | +3...+5°C | +15°C | +6...+8°C |
| Freezer temperature | -18°C | -18°C | -6...-10°C |
| Electricity consumption | Normal | Minimum | Reduced |
| Compressor operation | Cyclic | Rare | Short cycles |
Alternative methods and external timers
Since it is impossible to programmatically turn off only the freezer compartment using the standard means of refrigerators Atlant (especially older series), leaving the refrigerator compartment, users often resort to external solutions. The most effective and safest method is to use a timer socket.
The timer socket allows you to set power on and off cycles for the entire device. For example, you can set up a cycle: 30 minutes working, 30 minutes resting. During periods of “rest”, the temperature in the freezer will slowly increase, and in the refrigerator it will remain longer due to better insulation and lower heat capacity of the air. This allows you to simulate the operation of only the refrigerator compartment, albeit with temperature fluctuations.
When using such methods, it is important to be careful:
- ⏱️ Shutdown intervals should not be too long so that the food in the upper compartment does not have time to spoil.
- 🔌 The power of the timer must be appropriate starting current of the refrigerator compressor.
- 🌡️ It is necessary to constantly monitor the temperature inside the chambers with a thermometer in the first days of using such a circuit.
This method is especially relevant for country refrigerators or older models, where there are no electronics, and the need for savings or a specific storage mode is high. However, remember that frequent on/off cycles may shorten the life of the compressor.
⚠️ Warning: The use of external timers may void the warranty on new equipment. Use this method only on devices out of warranty.
Frequent errors and precautions
When trying to achieve isolated operation of cameras, users often make mistakes that can lead to equipment failure. One of the most common is an attempt to block the air supply channels to the freezer yourself, by sealing the holes with tape or plugging them with rags. It is strictly forbidden to do this Blocking the air flow disrupts the operation of the fans (in No Frost systems) and leads to overheating of the compressor, since freon does not give off heat in the evaporator. This may cause the motor to jam or the system pipes to rupture. It is also not recommended to leave the refrigerator turned on with the doors open to “ventilate” the freezer if food remains inside - this will lead to their spoilage and the formation of ice on the evaporator..

Another mistake is ignoring alarms. If the model is equipped with an audible temperature alarm, it will constantly beep when attempting to manipulate the temperature regime. In such cases, it is better to use the mute button, if there is one, but do not ignore the very fact of changing the storage conditions of the products.
FAQ: Frequently asked questions
Is it possible to completely turn off the freezer with the button without removing the cord from the outlet?
In most models Atlant there is no separate button to completely turn off only the freezer compartment. The Holiday function turns off the refrigerator compartment, not the freezer compartment. Paul
