Owners of modern household appliances often face situations when it becomes necessary to temporarily decommission one of the chambers of the refrigeration unit. Atlant two-compressor refrigerator is designed in such a way that it allows you to control freezer and refrigerator compartments independently of each other. This design solution provides the advantage of being able to turn off the freezer, while leaving the main compartment working to cool food.
Such a need may arise for various reasons: from banal defrosting and cleaning to the need to save energy during a long absence of deep-frozen products. It is important to understand that individual control system in models with two compressors, it significantly simplifies the process, but requires compliance with certain safety rules to prevent damage to equipment.
In this article we will analyze in detail the algorithms of action for various series of refrigerators Atlant, consider the operation of thermostats and electronic control panels. You will learn how to correctly carry out the procedure without risk to the compressor and refrigerant, as well as what operating nuances owners of equipment with a system No Frost or drip defrosting should take into account.
The principle of operation of a two-compressor cooling system
The fundamental difference between equipment Atlant with two compressors is complete autonomy of the cooling circuits. While in single-circuit models one motor drives the refrigerant throughout the entire volume, here each compartment is responsible for its own unit. This means that stopping one of them does not affect the operation of the other, which is physically impossible in systems with one motor without loss of cold in the entire volume.
Each compressor has its own thermostat or electronic control unit, which reads the temperature in its zone. When you change settings or turn off power to the freezer, the second compressor continues to operate as normal, maintaining the set parameters in the refrigerator compartment. This scheme significantly reduces the load on the electrical network during startup, since the engines do not start at the same time.
⚠️ Attention: Despite the independence of the circuits, heat exchange between the chambers through common walls and seals is maintained. Long-term shutdown of the freezer while the refrigerator is running can lead to a slight increase in temperature in the main compartment due to thermal inertia.
The technical implementation of separate control may vary depending on the year of manufacture and series of your of the Atlant refrigerator. Older models use mechanical thermostats, while modern versions are equipped with electronics. Understanding the type of control is critical for correctly performing the shutdown procedure.
Preparing the equipment to turn off the camera
Before you begin manipulating the settings or power supply, you must properly prepare the contents of the freezer compartment. If you plan to completely defrost, all food should be removed or placed in thermal containers in advance to avoid spoilage as the temperature rises. For two-compressor models this is especially true, since the main refrigerator will continue to work.
It is important to free up space around the unit, providing access to the rear wall and the base where the compressor is located. Make sure that the floor is dry and clean, as during defrosting it may be necessary to collect melt water if the design does not provide automatic drainage to the evaporator. Check the condition hoses and tubes for visible damage before any intervention.
- 🧊 Completely empty the freezer compartment of food and drawers.
- 🔌 Prepare dry rags and a container for collecting water on case of mechanical defrosting.
- 📖 Find the technical data sheet of your model Atlant to clarify the control circuit.
- ⏱️ Plan the shutdown time so that it does not coincide with the hours of peak voltage in the network.
If your goal is not defrosting, but temporarily stopping the operation of the freezer to save energy, make sure that there are no quickly perishable foods left in the chamber. Even when turned off, the insulated chamber will keep the cold for some time, but this will not replace the full operation of the compressor.
☑️ Preparing to turn off the freezer
Disconnection methods via the control panel
Modern refrigerators Atlant with electronic control allow you to turn off the cameras programmatically. This is the safest and most correct method provided by engineers. The front panel usually contains a display and control buttons that allow you to adjust the temperature or activate special modes.
To turn off the freezer, you need to find the button responsible for setting the temperature of this particular compartment (often indicated by a snowflake or a letter F). By pressing it, increase the temperature value to the maximum (usually this is +5...+8°C) or until the shutdown symbol appears (a dash or OFF). Some models require a long press (3-5 seconds) to activate the shutdown mode.
⚠️ Attention: In models with the No Frost system, complete software shutdown may not be provided by the manufacturer. In such cases, the system can automatically start the fan or heating element if the sensors detect a critical change in conditions.
If the alarm indicator lights up on the display or a sound signal is heard, this is a normal reaction of the system to the lack of cold. The alarm can usually be turned off with a separate button, but the camera operating mode itself will remain changed until you return the settings back. Electronics Atlant reliably remembers the last set parameters.
What to do if the button does not respond?
If pressing the buttons on the electronic panel does not change the indicators, the child lock may be activated. Find the button with the image of a lock and hold it for 3-5 seconds until the corresponding sound signal appears or the indication changes. After removing the lock, repeat the procedure for changing the temperature.
Mechanical regulation of thermostats
In classic models Atlant, where control is carried out by mechanical regulators, the process looks different. Here, a thermostat, which is a device with a bellows and a contact group, is responsible for the temperature. Turning the freezer control knob counterclockwise to the extreme position opens the contacts and stops the Atlant compressor. On the scale of a mechanical thermostat, the extreme position is often indicated by a dot, a word, or number compressor.
On the scale of a mechanical thermostat, the extreme position is often indicated by a dot, the word OFF or number 0. When you move the handle to this position, you will hear a characteristic click - this is a sign that the electrical power supply circuit to the engine is broken. The freezer compressor will stop while the second motor continues to operate.
Some users practice setting the minimum temperature (warmest setting) without turning the thermostat completely off. However, for a complete shutdown, for example, for defrosting, it is necessary to open the circuit. Mechanical thermostats are reliable, but over time their calibration may get lost, so you should rely on scale divisions with caution.
| Type of regulator | Shutdown designation | User action | Indication |
|---|---|---|---|
| Mechanical (old) | Point or 0 | Rotate counterclockwise | Click, silence |
| Electronic (display) | OFF symbol or - | Short/long presses | Camera screen goes dark |
| Semi-electronic | Green indicator | Slider adjustment | Changing lamp color |
| Touch | Lock/power icon | Touch screen | Beep |
When working with mechanical handles, avoid excessive force. If the regulator is tight, do not use force, as you can break the plastic rod or the internal axis of the thermostat. Smooth rotation is the key to longevity control body.
Physical shutdown of compressor power
There are situations where software or mechanical methods are unavailable or faulty. In this case, you can resort to physically turning off the power to a specific compressor. This method requires caution and basic knowledge of electrical engineering, as it involves working with electrical voltage. Two-compressor refrigerators often have separate switching inside the case, but a single power cord. To disconnect just one motor, you must access the terminal block or start relay of the specific unit. Typically, compressors are located in a niche in the lower rear part of the housing. electrical voltage.
Double compressor refrigerators Atlant often have separate switching inside the case, but a single power cord. To disconnect just one motor, you must access the terminal block or start relay of the specific unit. Typically, compressors are located in a recess at the lower rear of the housing.
Sequence of actions:1. Unplug the refrigerator (pull out the plug).
2. Remove the rear protective cover (crankcase).
3. Find the start relay of the desired compressor.
4. Carefully remove the relay or disconnect the power supply.
After completing the manipulations, the cover is put in place and the refrigerator is turned on. Only one circuit will work. This method is good for long-term preservation of the freezer, but is inconvenient for regular use, since it requires climbing to the back wall every time.
Features of defrosting when the refrigerator is running
One of the main advantages of the two-compressor circuit is the ability to defrost the freezer without removing food from the main compartment. However, there are some nuances here. While the main circuit is running, the walls between the chambers can cool, which slows down the melting of ice in the turned off freezer.
To speed up the process, you can leave the freezer door open. In this case, the main refrigerator will continue to gain cold, and its compressor may work in increased mode, trying to compensate for the influx of warm air through the open door of the adjacent compartment. This will temporarily increase electricity consumption.
Do not use hair dryers or other heating devices to speed up the thawing of ice. A sharp temperature change is dangerous for the plastic elements of the internal lining and the evaporator. Natural melting or using bowls with warm water (closed with a lid) are the only safe methods for Atlant refrigerators.
⚠️ Attention: During defrosting, make sure that water does not flow into the channels of the No Frost system (if any) or onto the floor. Moisture that gets into the technical holes can cause corrosion or a short circuit when turned on again.
Frequent errors and precautions
When turning off one of the cameras, users often make mistakes that can shorten the life of the equipment. One of the common problems is trying to turn on the compressor immediately after turning it off. Refrigerant and the oil must have time to flow to the required zones, and the pressure in the system should equalize.
If you turned off the freezer mechanically or through the panel, do not try to start it again earlier than after 10-15 minutes. Electronics may have a built-in delay, but a mechanical thermostat does not have this protection. Frequent starts lead to wear and tear of the starting relay and the engine itself.
- ❄️ Do not leave the door open for a long time unattended so as not to overheat the operating compressor of the main compartment.
- 🔌 Do not use extension cords and tees when temporarily turning off/on - only direct connection to socket.
- 🧹 Do not use sharp objects to chip ice, even if the camera is turned off.
It is also worth remembering that rubber door seals can “stick” during prolonged inactivity or, conversely, dry out if you do not wipe them periodically. Maintenance of the equipment is mandatory even during the period when one of the chambers is not used for its intended purpose.
Frequently asked questions (FAQ)
Is it possible to operate a two-compressor Atlant with the freezer turned off all the time?
Technically this is possible, since the compressors are independent. However, manufacturers do not recommend keeping one of the circuits disconnected (for a long time) unless necessary. This can lead to acidification of the oil in an idle compressor or disruption of the refrigerant circulation in its circuit. If the freezer is not needed, it is better to keep it turned off, but clean and dry, periodically turning it on for a short time.
Why, after turning on the freezer, does it not freeze for a long time?
After a long period of inactivity or defrosting, the system takes time to return to mode. The compressor needs to drive the refrigerant throughout the circuit and cool the evaporator. B two-compressor models this process can take from 2 to 6 hours. Do not load the chamber with food until the temperature stabilizes.
Does turning off the freezer affect energy consumption?
Yes, electricity consumption is reduced, but not by 50%, as many people think. The main energy consumer, the refrigeration chamber compressor, continues to operate. In addition, heat exchange between the chambers may cause the main motor to work a little harder. The savings will be approximately 30-40% of total consumption.
What to do if the red light is on after switching on?
The red indicator indicates an increased temperature inside the chamber. This is normal immediately after switching on or defrosting. If after several hours of operation (3-4 hours) the light does not go out, check the tightness of the door, the position of the thermostat and the absence of excessive loading of food.
