Disconnecting the freezer compartment in a two-compressor Atlant refrigerator

Two-compressor models of refrigeration equipment from the brand Atlant are deservedly popular due to their reliability and the ability to independently control temperature conditions. Owners of such equipment are often faced with a situation where it becomes necessary to temporarily or permanently turn off the freezer compartment, leaving the refrigeration compartment running. This may be due to defrosting, a long departure, or a desire to save energy if the freezer is empty.

The main advantage of the two-compressor circuit is the autonomy of the circuits. Unlike single-circuit systems, where turning off one compartment is physically impossible without stopping the entire unit, here different motors are responsible for cooling the freezer and refrigerator. Independent work allows you to manipulate modes without the risk of defrosting food in the main compartment. However, even in such a system there are some nuances that must be taken into account in order not to damage the equipment.

Before taking any action, it is important to understand the design features of your model. Some modern versions are equipped with electronic control with a “Vacation” function, while simpler models require mechanical intervention or the use of temperature regulators. Complete shutdown of the freezer compressor is only possible by setting the regulator to the “0” or “Off” position, if such an option is provided for by the thermostat design.

The principle of operation of a two-compressor systems

The design is based on the division of the refrigerant into two independent circuits. One freon circuit with its own compressor serves the refrigeration compartment, and the second, completely autonomous, is responsible for low temperatures in the freezer. This means that the breakdown or shutdown of one of the components does not in any way affect the performance of the other. Refrigerant circulation Each circuit is regulated by its own thermostat or electronic control unit.

When you regulate the temperature in the freezer, you act exclusively on the control circuit of the lower compressor. The upper motor, which cools the main compartment, continues to operate normally, maintaining the set parameters. This scheme ensures high energy efficiency, since the motors turn on only when it is really necessary to maintain cold in a particular zone.

It is worth noting that despite the autonomy, heat exchange between the chambers still occurs through common walls. Therefore, if you turn off the freezer completely, the temperature inside it will gradually rise, and some of the cold may go into the refrigerator compartment, causing the upper compressor to work a little harder. However, this influence is minimal and does not interfere food safety in the main compartment.

⚠️ Attention: Do not try to physically cut the wires or disassemble the electrical circuit of the refrigerator to turn off the motor. This will void the warranty and may cause a fire.

Mechanical shutdown through the temperature controller

In most models Atlant with mechanical control, the process of shutting off the freezer is carried out directly through the temperature controller. There are usually two handles located on the front panel or inside the compartment: one for the refrigerator, the other for the freezer. To stop cooling in the lower compartment, you need to turn the corresponding knob counterclockwise until it stops.

Indication that the compressor is turned off is a characteristic click and the engine stops running (if it was currently running). On the regulator scale, this position corresponds to a number 0 or a special inscription Off. In some modifications, the handle can be turned further, making a click, which signals the opening of the thermostat contacts.

It is important to understand that with this method of switching off, the light in the chamber may continue to burn if it is not connected to the operation of the compressor (which is rare). Thermostat it simply stops giving a signal to start the engine, but the electrical circuit backlight can remain active. If you plan not to use the freezer for a long time, it is also recommended to defrost it and leave the door ajar.

Electronic control and "Vacation" mode

More modern models of the brand Atlant equipped with an electronic display and control panel. In such devices, turning off the freezer can be done programmatically. Manufacturers often introduce a special mode, which is commonly called “Vacation” or “Eco”. When this function is activated, the refrigerator switches to an economical operating mode.

Usually, the “Vacation” mode involves increasing the temperature in the refrigerator compartment to +15°C, which prevents the appearance of mold and odor, while the freezer can either remain cold or turn off, depending on the specific model. Read the instructions carefully to your specific model, since the logic of the electronics may differ for different series. In some cases, to turn off the freezer, you need to set the temperature to maximum (for example, +5...+8°C), if the design allows such a range in the lower compartment.

If the alarm indicator lights up on the display or the temperature is flashing, this may indicate that the selected mode is not supported or the operating conditions are violated. Electronics Atlant are sensitive to voltage drops, so when setting modes, make sure that the power supply is stable.

Nuances of operation with the freezer turned off

Operating a refrigerator with the freezer turned off has its own characteristics. First of all, this concerns the temperature regime inside the refrigerator compartment itself. As already mentioned, the absence of active cold from below may slightly increase the overall temperature inside the unit, but for the main compartment this is not critical.

However, if the freezer is turned off for a long time, condensation will begin to form inside it, and then moisture. To avoid the appearance of an unpleasant odor and the growth of bacteria, the chamber must be thoroughly washed and dried. The freezer door In this case, it is better to keep it slightly open, ensuring air circulation.

It is also worth considering that the compressor of the refrigeration compartment may begin to work longer than usual, trying to compensate for the heat coming from warm freezer through the partition. This is a normal process, but it can lead to an increase in energy consumption, which paradoxically negates the point of saving if the freezer is simply turned off, but not defrosted.

Saving energy: myths and reality

Many users wonder how profitable it is to turn off the freezer in a two-compressor refrigerator. Theoretically, stopping one of the two compressors should reduce energy consumption by almost half. In practice, the numbers may differ. The second compressor, responsible for the refrigeration compartment, will continue to consume current, and its work may become even more intense due to heat gain from the warm freezer.

The real savings are noticeable if the freezer is empty and not used for months. If you just set the temperature in it to a minimum, the compressor will still turn on periodically to maintain the set (albeit high) value. Complete shutdown via 0 on the regulator is the only way to guarantee stop the motor.

Let's compare energy consumption in different operating modes:

⚠️ Attention: Different models Atlant The power of compressors may vary. The indicated percentages are averaged and depend on the volume of the chambers and the energy efficiency class.

Frequent errors when turning off the chamber

When trying to adjust the operation of the refrigerator, users often make mistakes that can shorten the service life of the equipment. One of the most common is trying to turn off the freezer by unplugging the cord from the outlet for a short time. This is absolutely useless for selective shutdown and is harmful for compressors.

Another mistake is setting the freezer temperature control to minimum cooling (the maximum number) with the idea that it is “resting”. On the contrary, you force the motor to work at its limit, trying to reach ultra-low temperatures, which leads to overload. Correct shutdown This is always moving the regulator to the “Off” position.

Also, do not forget about defrosting. If you unplug your freezer, there will be ice left in it. At room temperature it will begin to melt. If water is not properly drained, it may get on electrical components or leak onto the floor. Always use a tray to collect melt water.

Return to normal operation

When the need to turn off the freezer is no longer necessary, it is important to correctly return the refrigerator to operating mode. Sudden switching on of full load is not recommended. First, make sure the camera is dry and clean. Then turn the temperature control to the middle position (usually this number 3 or 4).

After turning on, the compressor will take time to reach the required temperature. In two-compressor models Atlant this process can take from 2 to 6 hours depending on the ambient temperature in the room. Do not load the freezer with food immediately. Let it work idle to stabilize temperature conditions.

If after turning on you hear unusual sounds or the compressor does not start within an hour, check the position of the regulator. Sometimes the thermostat contacts can “stick”, and a light knock on the regulator body (without fanaticism) helps to close them. If the problem persists, diagnostics will be required.

Is it possible to turn off the freezer if there is only one refrigerator?

In single-circuit refrigerators (one compressor for both chambers), it is impossible to turn off the freezer separately. Stopping the cooling will lead to defrosting of all products. There are models with the “Full No Frost” system and special valves, but classic Atlantakh with one motor this is not provided.

Why did the refrigerator become warmer after turning off the freezer?

This may occur due to a violation of heat exchange. The warm freezer has become a source of heat for the refrigerator compartment. Also check that. Are the settings of the main thermostat lost? Perhaps the refrigerator compressor simply cannot cope with the increased heat load.

Is it harmful for the compressor to remain in the “0” position for a long time?

No, it is not harmful. The “0” position on the thermostat simply opens the electrical circuit, which is even more favorable for its resource. constant on-off cycles. The main thing is to ensure ventilation inside the chamber to avoid corrosion.

How to find out which compressor has worked?

In two-compressor models Atlant the motors are usually located at the bottom, at the back. They can work independently. You can hear which one is humming, or you can feel the vibration on the back. wall of the corresponding chamber. If the bottom is humming, the freezer is working, if the upper part of the rear panel is warm and a sound is heard from above, the refrigerator compartment is working.
