The need to temporarily or permanently turn off one of the chambers in a two-chamber refrigerator Atlant occurs among users for various reasons, ranging from preparation for a long departure to the desire to save energy with a minimum load. The owner is often faced with a dilemma: is it possible to turn off only the freezer or refrigerator compartment, leaving the second one to work? The answer to this question depends on the specific model of your unit and the type of temperature control system installed. In older models with one compressor and mechanical control, complete shutdown of one zone without affecting another is technically impossible without intervention in the design.
Modern models, especially those equipped with a system No Frost or electronic control, provide more flexibility in setting operating modes. However, even here there are limitations dictated by the physics of the refrigeration circuit. If you plan to turn off the chamber for defrosting or cleaning, the procedure is the same, but if the goal is to change the operating mode to save energy or store specific products, the approach should be different. It is important to understand that incorrect actions can lead to damage to the compressor or defrosting of food in the next compartment.
In this manual, we will analyze in detail the algorithms of actions for various series of equipment Atlant, explain the principles of operation of thermostats and warn about possible risks. You will learn how to use the “Super Freeze” function or the “Vacation” mode, and also in which cases the only correct solution is to completely disconnect the device from the power supply. A deep understanding of the structure of your refrigerator will allow you to operate it as efficiently and safely as possible.
The principle of operation of Atlant two-chamber refrigerators
To competently manage operating modes, you need to understand the basic architecture of the device. Most two-compartment refrigerators Atlant use one compressor, which pumps refrigerant into the evaporator. Cooled air or directly cold freon is distributed to both compartments. In the classic scheme, the evaporator is located in the freezer, and cold air circulates into the refrigerator compartment through special channels or due to natural convection.
The key control element is thermostat (thermostat). In models with mechanical control, it is usually alone and controls the temperature in the freezer, and the flow of cold into the upper chamber is regulated by a damper or simply by the intensity of the compressor. This means that when the compressor is turned off, heat stops being removed from both chambers at the same time. An attempt to isolate one chamber from the cold of another in such systems is not structurally provided by the manufacturer.
⚠️ Attention: In models with one compressor, it is impossible to turn off the cold supply to one chamber, leaving the other working, using only standard controls. Disabling the thermostat will stop the entire cooling cycle.
The situation changes in models with two compressors. Here the refrigerator and freezer compartments have independent cooling circuits. Each compartment is controlled by its own thermostat and its own motor-compressor. This allows you to completely turn off one camera while the second continues to operate normally. You can determine the type of your refrigerator by the marking on the nameplate or by the presence of two temperature regulators inside the chamber.
Features of models with one and two compressors
Determining the number of compressors is the first step before trying to change the operating mode. In single-compressor units, which make up the majority of the fleet Atlant, the refrigerant passes sequentially through the evaporators. Even if the instructions indicate the presence of the “Super Freeze” function, it only forces the compressor to work continuously, without turning off the refrigeration chamber, but on the contrary, often overcooling it.
Two-compressor models, such as some series XM-4008 or XM-6025, are structurally separated. They have two separate circuits, two capillaries and two thermostats. This gives the user a real opportunity to turn off, for example, the freezer if it is not needed, and use only the refrigerator compartment, which significantly reduces energy consumption.
To accurately determine the type of your model, use the following comparison table:
| Characteristics | One compressor | Two compressors | |||
|---|---|---|---|---|---|
| Number of regulators | One (usually) | Two (separately for each chamber) | |||
| Independence of operation | None | Complete independence | Ability to turn off one camera | Only by completely unplugging it from the socket | Yes, through the control panel or thermostat |
| Energy consumption | Higher when working on full | Below when using one camera |
If you find that you have a model with one motor, do not try to mechanically block the air supply channels or seal the holes. This will disrupt circulation, lead to the formation of ice jams and may cause a change in pressure in the system. The design of the refrigerator compressor overheating due to changes in system pressure. Refrigerator design Atlant is designed to operate in a certain heat balance.
Using the "Vacation" and "Super Freeze" functions
Many users confuse the mode "Vacation" with the ability to turn off the camera. In refrigerators Atlant with electronic control, this mode is designed to operate the refrigerator compartment in economy mode with a minimum load, while the freezer continues to operate normally. The temperature in the upper compartment rises to +15...+17°C, which prevents the appearance of mold and odor, but does not allow storing perishable products.
Function "Super Freeze" (often indicated by a snowflake or a button with the number 7 on the mechanics) works differently. It forcibly turns on the compressor in continuous operation mode, bypassing thermostat stops. This is necessary for quick freezing of large volumes of food. In this mode, the refrigerator compartment also cools more intensely, so it is impossible to leave the mode on for a long time - this will lead to freezing of food in the upper compartment.
Is it possible to keep the Super Freeze mode constantly?
No, this will lead to accelerated wear of the compressor and freezing evaporator. The mode is intended for short-term use (up to 24-48 hours).
To activate the “Vacation” mode on electronic panels, you must press the corresponding button. There is no such function on mechanical models, and you can simulate it by setting the thermostat to the minimum value (number 1 or Min), however, this will not turn off the chamber completely, but will only reduce the cooling intensity.
⚠️ Attention: The “Vacation” mode does not turn off the refrigerator completely, but only maintains its temperature above the freezing point of water, but below the temperature of bacterial growth. Products cannot be stored in this mode.
Instructions for turning off the chamber in two-compressor models
If your Atlant is equipped with two compressors, the procedure for turning off one of the chambers is simple and safe. You don't need to reach inside the device or unscrew the wires. All control is carried out through the temperature control panel.
To turn off the freezer or refrigerator compartment, follow these steps:
- 🔌 Find the temperature regulator responsible for the chamber you want to turn off (usually they are labeled or located next to the corresponding compartment).
- ❄️ Turn the regulator knob counterclockwise until it stops.
- 🛑 In the “Off” or “0” position you will hear a light click - this is the opening of the thermostat contacts.
- ✅ Check that the compressor responsible for this chamber has stopped buzz, and work continues in the next chamber.
☑️ Checklist before turning off the camera
In models with electronic control, just press the camera selection button and hold the temperature reduction button until a dash or the “Off” symbol appears on the display. After this, the system will automatically stop supplying refrigerant to the selected circuit.
What to do if there is only one compressor: alternative solutions
Owners of single-compressor refrigerators Atlant have it more difficult. As mentioned earlier, you cannot disable one camera using standard methods. However, if your goal is to save energy or use the refrigerator only as a freezer (or vice versa) on an ongoing basis, there are technical solutions that require qualifications.
One of the options is to install an additional thermostat in the compressor power circuit, which will turn off the unit when a certain temperature is reached in the desired chamber. But this is a complex modification that violates the factory warranty. A simpler, but less effective method is to adjust the air damper (if there is one). By blocking the cold air supply channel from the freezer to the refrigerator compartment, you can turn a two-chamber freezer into a single-chamber freezer.
Important: In models with a weeping evaporator (drip system) in the refrigerator compartment, this method is dangerous. If you block the outflow of heat, the moisture will stop evaporating, and the entire chamber will become covered with ice, and the compressor will work for wear.
Safety rules and common mistakes
Whenever manipulating the refrigerator settings Atlant it is important to follow safety precautions. The most common mistake is trying to “trick” the thermostat by sealing its sensitive element or heating it with a hairdryer to turn off the compressor. This leads to failure of the thermostat itself and the risk of freon leakage if the tubes are damaged.
Another mistake is frequent switching of modes. Sudden changes in temperature conditions place a high load on the oil in the compressor and can shorten the service life of the unit. If you switched the refrigerator to the “Vacation” mode or turned off one of the chambers, allow the system to stabilize for 5-6 hours before loading with food.
Do not forget that when you turn off one of the chambers in a two-compressor model, heat exchange between them through a common partition still occurs. Therefore, the disconnected camera will slowly heat up (or cool down) under the influence of its working neighbor. This is normal, but requires monitoring if you store temperature-sensitive substances there.
⚠️ Warning: Never use third-party timers to cycle the refrigerator on/off to regulate the temperature. This can damage the compressor start relay.
Is it possible to turn off a freezer in Atlanta with one compressor?
No using standard means. There is only one thermostat, and it controls the operation of the compressor for both chambers. Turning off the thermostat will stop cooling everywhere. The only option is to mechanically shut off the air supply channel, but this will disrupt the operation of the refrigeration chamber.
What does a flashing indicator mean after the chamber is turned off?
In electronic models Atlant blinking may signal an increase in the temperature in the compartment. If you just turned off the camera, it's normal that the temperature is rising. If it lights up constantly after turning on, check that the door is closed tightly.
How to understand which compressor is responsible for what in a two-compressor refrigerator?
Usually compressors are numbered. Compressor No. 1 is most often responsible for the freezer compartment, and No. 2 for the refrigerator compartment. However, in different series Atlant numbering may differ. The easiest way to trace it is through the tubes: the tubes from the compressor go to the evaporator of the corresponding chamber.
Is it harmful for a refrigerator to work for a long time in the “Vacation” mode?
No, this mode is specially designed for long-term operation in the absence of owners. It saves energy and prevents damage to seals and the appearance of odors inside the empty chamber.
