Two-compressor brand refrigerators Atlant are deservedly popular due to their reliability and the ability to independently control temperature conditions. However, owners of such units often face the question: how to properly turn off the freezer without disrupting the operation of the entire system? This may be necessary for defrosting, saving energy, or storing food for a long time only in the main compartment. It is important to understand that the design features of a dual-circuit cooling system require the presence of separate thermostats, which greatly simplifies the local shutdown procedure.
Unlike single-compressor models, where shutting off one zone is often impossible without stopping the entire unit, equipment Atlant with two motors allows you to flexibly control the climate inside. Freezer in such devices it functions as a stand-alone module. Incorrect actions can lead to failure of the electronics or the compressor, so it is important to strictly follow the algorithm described in the technical documentation. Below we will look at all the nuances of this process.
Before starting any manipulations, you need to make sure that you understand the structure of your specific device. Models may differ in the type of control: mechanical or electronic. The sequence of your actions depends on this. Ignoring technical features may result in the system going into emergency mode or no longer maintaining the temperature in the main compartment.
The principle of operation of a two-compressor system
The fundamental difference between two-compressor refrigerators is the presence of two independent refrigerant circuits and two motor-compressors. One compressor is solely responsible for cooling the refrigerator compartment, and the second is responsible for freezing food in the lower or upper chamber. This scheme allows independently regulated temperature in each compartment, which is a key advantage over single-circuit systems.
When you turn off one of the chambers, the second compressor continues to operate as normal, maintaining the set temperature in the remaining active zone. This is especially convenient if you need to defrost the freezer without removing food from the main compartment. Thermostats or electronic control boards in the models Atlant are distributed in different circuits, which minimizes the risk of failures.
It is worth noting that even with the freezer compartment turned off, some models can retain slight cold in this compartment due to heat exchange through the partitions, but not complete freezing will be. Complete shutdown of the freezer compressor occurs only when the corresponding regulator is moved to the “Off” or “0” position. Understanding this physics of processes will help you avoid panic if you hear that one motor is working and the second is silent.
Why two-compressor models quieter?
Two lower-power compressors operate quieter and more efficiently than one powerful one, since each of them turns on less often and operates at lower speeds, creating less vibration.
Preparing to turn off the freezer compartment
Before you begin setting up the regulators, it is necessary to carry out a number of preparatory measures. This will ensure the safety of the procedure and the safety of the products. First of all, assess the number of frozen goods: if there are a lot of them, plan where you will put them, since the temperature will begin to rise immediately after the compressor stops.
The second important stage is checking the condition of the rubber seals on the doors. If you plan to keep the freezer unplugged for a long time, but open (for ventilation), make sure that the door will not slam shut spontaneously. It is also recommended to clear the space around the refrigerator to ensure normal ventilation, even if only one circuit is running.
Do not forget to prepare a container to collect melt water if your goal is defrosting. In two-compressor models Atlant often there is no No Frost system in budget series, so the formation of an ice coat is a natural process. The presence of a tray or rags at the base of the unit will save the floor covering from moisture.

Mechanical control: step-by-step instructions
In most models Refrigerators Atlant with mechanical control use rotary thermostats. They are usually located on the top panel of the case or inside the refrigerator compartment. Dual-compressor versions are characterized by the presence of two separate “knobs,” often marked with numbers from 1 to 7 or the inscriptions “Min” / “Max.”
To turn off the freezer, you need to find the regulator that is responsible specifically for it. It is often marked with a snowflake or the words "Freezer". Turning the knob counterclockwise all the way to position 0 or Off breaks the electrical circuit of the freezer compressor. The click that you can hear indicates the opening of the thermostat contacts.
☑️ Algorithm for turning off the mechanics
After turning the regulator to zero, the freezer compressor should stop within a few minutes. If you hear a humming noise, don't be alarmed - it could be the main motor. Make sure you do not mix up the controls, as turning off the main refrigerator will spoil fresh food.
⚠️ Attention: Do not use excessive force when turning the thermostat knob. Mechanical switches have limited travel, and forced rotation beyond the “0” limit can break the plastic rod inside the housing.
Electronic control and display
Modern models Atlant are often equipped with an electronic control unit with a digital display. Here the shutdown process looks different and requires sequential button presses. The interface may differ depending on the series, but the logic remains similar: you need to enter the settings menu or use a dedicated button for each camera.
Usually there is a button on the panel with an image of a snowflake or a caption corresponding to the freezer. A short press can change the temperature, and a long press (3-5 seconds) will often put the camera into off mode. In this case, the symbol of a crossed out snowflake or the inscription OFFmay appear on the display. Some models require you to press a combination of buttons, such as "Mode" and "Temperature" at the same time.
If the alarm indicator lights up on the display or the temperature flashes, this is normal for the transition period. The electronics records the change set parameter and stops sending a signal to turn on the freezer compressor. It is important to wait until the system stabilizes and stops beeping.
In models with the function Smart Control or connection to Wi-Fi, disconnection can be done remotely through the application. This is convenient if you are away from home and want to have the refrigerator ready to defrost when you arrive. However, for initial setup it is better to use a physical control panel.
Nuances of operation in single camera mode
The operation of a two-compressor refrigerator with one working chamber has its own characteristics. First of all, this concerns heat transfer. The partition between the compartments is not an absolute thermal insulator, so the cold from the main compartment may partially penetrate into the turned off freezer. This can lead to the formation of condensation on the walls of the idle chamber.
To avoid the appearance of mold and unpleasant odors, it is recommended to keep the door of the disconnected freezer slightly open, if the design allows, or regularly wipe the internal surfaces with a dry cloth. It is also worth considering that the main compressor can work in a more intense mode if you often open the freezer door, letting warm air in.
| Parameter | Both compressors on | Freezer off | Refrigerator off |
|---|---|---|---|
| Energy consumption | Maximum | Reduced by ~40-50% | Reduced by ~40-50% |
| Temperature in the freezer | -18°C and below | Increases to room temperature | Increases to room temperature |
| Temperature in the refrigerator | +2...+5°C | +2...+5°C (state) | Grows to room level |
| Noise background | Medium/High | Low (1 motor) | Low (1 motor) |
Possible problems and their solutions
During operation in partial shutdown mode, users may encounter a number of non-standard situations. For example, a refrigerator Atlant may continue to hum even after the freezer is turned off. Most often, this is the main compressor working, but if you are sure that you have turned off both regulators, and the sound does not stop, the relay may be faulty or the contacts are stuck.
Another common problem is the appearance of ice in the switched-off chamber. This occurs due to high humidity in the room and its entry into the room when the doors are opened. There is only one solution: regularly dry and check the integrity of the main compartment door seal, which can let cold in.
⚠️ Attention: If, after turning off the freezer compartment, the main refrigerator stopped freezing or started working without stopping, there may have been a problem in the refrigerant circulation or a failure in the electronic module. In this case, diagnosis by a specialist is necessary.
It is also worth mentioning the smell. Stagnant air in an idle chamber quickly takes on a musty hue. To avoid this, you can put an open container with activated carbon or a special odor absorber inside. This is especially true if the freezer is turned off for a long period of time.
Frequently asked questions (FAQ)
Is it possible to completely unplug the cord from the outlet to turn off the freezer?
No, this will turn off the entire refrigerator, including the main compartment. To isolate the freezer, you must use the built-in regulators or control buttons on the body of the device.
How long does the freezer keep cold after switching off?
When fully loaded with food and the door closed, the temperature can stay up to 10-15 hours. An empty chamber will warm up to room temperature in 2-4 hours, depending on the temperature in the room.
Is it harmful for the compressor to operate only one of the two?
No, two-compressor systems Atlant are designed specifically for independent operation. The compressor life is not reduced when operating in single mode if the temperature mode is selected correctly.
What to do if the regulator does not turn to zero?
Do not use force. Perhaps in your model range the minimum value is not indicated by zero, but by one or the word “Min”. In this case, you cannot completely turn off the camera through the regulator; you will need to disconnect from the network or call a technician to block the circuit.
Do you need to defrost the freezer before a long shutdown?
Yes, if you plan to keep the camera turned off for more than a day, the ice will melt and turn into water. It is better to defrost in advance, wash and, most importantly, dry the chamber, leaving the door ajar.
