Owners of Belarusian brand refrigerators Atlant often face a situation when the volume of the freezer becomes excessive, and the electricity consumption is high reduce. The question of how to turn off only the freezer compartment while leaving the refrigerator compartment running is one of the most discussed on home appliance forums. However, before you begin any manipulations with electrical wiring or settings, you must clearly understand the design features of your device. In most cases complete physical shutdown one of the circuits without consequences for the compressor is impossible.
Modern two-chamber models are more complex than they might seem at first glance. An attempt to roughly interfere with the electrical circuit can lead to failure compressoras it is designed to operate with a certain thermal load. In this article, we will look in detail at what standard methods exist to minimize the operation of a freezer, how electronic control systems work, and why mechanical shutdown is often a mistake. You will learn about the nuances of operating single-compressor and two-compressor systems.
It is important to immediately note that the universal “Turn off freezer” button does not exist in any model of household appliances. However, there are saving modes specific settings of thermostats that allow you to get closer to the desired result. We will look at the technical aspects of evaporator operation, the role of refrigerant and how changes in temperature affect the life of the unit. Understanding these processes will save you from expensive repairs.
The principle of operation of the Atlant refrigeration system
To understand why you can’t just “pull the cord” of the freezer, you need to understand the physics of the process. In classic models Atlant with one compressor, the refrigerant circulates through a single circuit, passing first through the freezer compartment and then through the refrigerator compartment. Temperature conditions is regulated by the amount of refrigerant entering the evaporator and the operating time of the compressor. If you artificially stop circulation in one of the compartments, the pressure in the system will change critically.
In models with a system No Frost or a “crying” evaporator, air often circulates between the chambers. Turning off the fan or heater in the freezer compartment will cause the cold to no longer be distributed evenly. This can cause defrosting of food in the upper chamber or, conversely, deep freezing where it is not required. Thermostat in such systems it usually controls the temperature in the freezer, so turning it off paralyzes the operation of the entire refrigerator.
⚠️ Attention: Attempt to break electrical circuit of the defrost heater or freezer fan without proper knowledge may result in a short circuit and fire hazard. Do not interfere with the factory circuit unless necessary.
Two-compressor models Atlant technically allow more flexible control, since each chamber has its own independent cooling circuit. However, even in them, the control panel usually does not provide the function of completely turning off one of the departments, leaving the other in working order. The designers assume that the refrigerator should operate normally. Violation of this balance leads to incorrect operation of electronic module control.
Why can’t you just shut off the capillary?
Pressing the capillary tube through which freon moves will lead to to an instant increase in pressure at the outlet of the compressor. This is guaranteed to disable the unit in a matter of minutes of operation, and repairs will cost more than a new refrigerator.
Models with one and two compressors
The key factor determining the temperature control capabilities is the number of compressors. In the line Atlant there are both options. Single-compressor models (series 40, 42, 45 and many others) have one motor that drives freon through both circuits simultaneously. In such systems independent shutdown it is physically impossible without disrupting the cooling cycle. Any attempt to isolate the freezer will result in the compressor working to wear out or not turning on at all due to the protection being triggered.
Two-compressor models (often series 60, 62 and higher) are equipped with two independent systems. Theoretically, it is possible to turn off the power to one of the compressors. However, in practice, this requires opening the technical compartment and tampering with the wiring, which voids the warranty and requires the qualifications of an electrician. The standard control panel of such refrigerators Atlant only allows you to regulate the temperature, but not completely turn off the circuits during operation.
- 🔹 Single-compressor models: single circuit, simultaneous operation of chambers, high energy consumption at full load.
- 🔹 Two-compressor models: independent circuits, possibility of theoretical separate control (requires modification), quiet operation.
- 🔹 Electronic control: allows precise adjustment of degrees, but does not have an “Off” function. freezer."
- 🔹 Mechanical control: adjustment is made by turning the thermostat knob, accuracy is lower.
It is worth considering that even if there are two compressors, the control system can block the start of one of them if the sensors detect incorrect operating conditions. Electronics of modern refrigerators Atlant is programmed for certain algorithms. Bypassing these algorithms is only possible by flashing the module, which is impractical in everyday conditions.
Temperature adjustment as an alternative to turning it off
Since completely turning off the freezer is impossible or impractical, the optimal solution is to set the maximum possible temperature in this compartment. In most models Atlant with electronic control, you can set the temperature in the freezer to -6..-8 °C. This is not enough for long-term storage of meat, but it is quite enough to maintain cold if you use the chamber as an additional refrigeration compartment.
In models with mechanical control, adjustment is made by turning the thermostat knob. Typically the scale goes from 1 to 7 or from Min to Max. To minimize cold, the handle should be moved to the 1 or Minposition. In this mode the compressor will turn on less often, and the temperature in the freezer will rise to the maximum possible value allowed by the design of the thermostat.
The temperature there will still be below zero. If your goal is to have extra space for vegetables or drinks, this option will not work as the food may freeze. However, for storing frozen semi-finished products that you plan to use quickly, this mode is ideal for energy saving.
Holiday Mode and its features
Many users confuse the ability to turn off the freezer with the Holiday Mode function. In refrigerators Atlant this mode is designed to save energy when the owners are absent for a long time. When Vacation is activated, the refrigerator compartment switches to minimum consumption, maintaining a temperature of about +12..+15 °C to prevent the appearance of mold and odor, but the freezer continues to operate in normal mode.
Some people mistakenly believe that this mode turns off the freezer, leaving cold in the main compartment. In fact, the opposite is true: “Vacation” protects the main chamber from damage, but the freezer continues to freeze. It is not possible to turn off the freezer compartment, leaving the refrigerator compartment in operating mode (for example, +5 °C), using this function. The design does not allow for a scenario where the freezer is warmer than the refrigerator. it won't work. The design does not allow for a scenario where the freezer is warmer than the refrigerator.
| Operating mode | Temperature in the refrigerator compartment | Temperature in the freezer | Energy consumption |
|---|---|---|---|
| Normal mode | +3..+5 °C | -18..-24 °C | Standard |
| Vacation mode | +12..+15 °C | -18 °C | Reduced |
| Max. temperature (knob 1) | +6..+8 °C | -6..-8 °C | Minimum |
| Full shutdown | Room temperature | Room temperature | 0 W |
Using the “Vacation” mode is only justified when you do not need the refrigerator compartment and the freezer is full of supplies. If the goal is the opposite, this mode is useless. The electronic control module Atlant strictly monitors the execution of the programmed programs, and the user is not given the opportunity to change the logic of their operation.
Technical limitations and risks of intervention
Attempts to independently turn off the freezer often end disastrously for the equipment. The most common mistake is trying to turn off the temperature sensor or defrost heater. In systems No Frost this leads to the evaporator becoming overgrown with ice, blocking the air ducts, and the refrigerator stops cooling altogether. The compressor may operate continuously, trying to reach an unattainable temperature.
Another risk is associated with the oil in the compressor. The refrigerant circulates along with oil, which lubricates the rubbing parts. If you change the pressure or stop circulation in part of the circuit, oil may remain in one of the compartments and not return to the compressor crankcase. This will lead to dry and fast work. Repair in this case will require replacing the motor and purging the entire system. compressor wedge. Repair in this case will require replacing the motor and purging the entire system.
⚠️ Attention: Interfering with the electrical circuit of the refrigerator automatically removes the device from warranty service. If the equipment is under warranty, any manipulations other than adjusting the thermostat knob are prohibited.
There are also models with one evaporator located in the freezer. Cooling of the refrigerator compartment occurs due to forced air circulation. If you try to stop the fan or close the damper, the cold will stop flowing into the upper chamber, but the freezer will continue to freeze. It is technically impossible to turn off only the freezer in such a scheme without stopping the entire cycle.
☑️ Check before changing the settings
FAQ: Frequently asked questions
Is it possible to physically disconnect the wires going to freezer?
Theoretically, you can turn off the power to the defrost heater or fan, but this will lead to incorrect operation of the entire refrigerator. On single compressor models this will cause icing and damage. In two-compressor systems, you need to turn off the compressor itself, which is difficult and unsafe without a specialist.
Why is there no information in the instructions about turning off the freezer?
Because the manufacturer Atlant does not provide for such operation. The refrigerator is designed as a single system. Improper use can lead to food spoilage and equipment breakdown, so this scenario is not described in the documentation.
What happens if you set the temperature in the freezer to maximum?
The temperature will rise to about -6..-8 °C. Foods that require deep freezing (-18 °C and below) will begin to spoil. However, for short-term storage of ice or already frozen food that will be used quickly, this is an acceptable energy saving mode.
Is there an "Eco" button to turn off the freezer?
No. The "Eco" or "Vacation" button usually puts the refrigerator compartment into economy mode (+12..+15 °C), but the freezer continues to work. There is no special function for turning off only the freezer in household models. Atlant does not exist.
In conclusion, it is worth saying that the desire to optimize the operation of equipment is commendable, but in the case of refrigerators Atlant it is better to use standard adjustment means. Setting the temperature to the minimum cooling level is the only safe way to reduce the load on your freezer. Any other methods carry high risks and may lead to the need to purchase a new unit.
