Owning reliable Belarusian household appliances production is often overshadowed by one inevitable procedure, ignoring which can lead to serious damage. A two-chamber Atlant refrigerator, equipped with two independent compressors, requires a special approach to maintenance, since the cooling system here is divided into two autonomous circuits. Unlike No Frost systems, it is necessary to manually remove ice, and this must be done strictly according to the manufacturer's regulations.
Many users mistakenly believe that the presence of two compressors simplifies the process, allowing only one chamber to be turned off, but this is not always safe for the motor and refrigerant. The correct sequence of actions guarantees the preservation of the life of the equipment and prevents the formation of puddles in the kitchen. We will consider a detailed algorithm of actions that will help you carry out maintenance safely.
Design features of a two-compressor system
The main difference between such models is the complete autonomy of the refrigeration and freezer chambers. Each compartment is served by its own compressor evaporator, which allows you to set different temperature conditions independently of each other. This means that when one part of the unit is defrosted, the second can continue to operate normally, keeping the food cold.
However, technically, the process of defrosting the evaporator in the freezer requires a complete stop of both compressors for safety. If active melting of ice occurs in the freezer, moisture can get onto the electrical contacts of an adjacent operating unit. Atlant system designed with this in mind, but it’s not worth the risk.
It is important to understand that the two-compressor circuit is more sensitive to voltage drops at the moment of switching on after inactivity. Therefore, before you start defrosting, make sure that your wiring is in good condition. Completely turning off both compressors before defrosting is imperative to prevent short circuits.
⚠️ Warning: Never try to speed up defrosting by running the refrigerator compressor while the freezer is open. This will lead to overload of the system and possible failure of the thermostat.
Preparation for the defrosting procedure
Before starting any manipulations, it is necessary to clear the space around the unit. Move refrigerator from the wall at least 50-70 centimeters to provide access to the back wall and the ability to freely walk around with rags. Prepare water containers and absorbent materials in advance.
The next step is to empty the chambers of food. All contents of the freezer and refrigerator compartment should be removed. If it’s winter outside, you can take the food out to the balcony, pre-packing it so that it doesn’t get airy. In the warm season, use thermal bags or transfer supplies to a nearby working refrigerator.
Don't forget to check the condition of the rubber seals on the doors before starting work. While the chambers are empty, inspect them for cracks or contamination that could affect the seal and cause excessive ice formation. The cleanliness of the seal is the key to proper operation heat removal system.
☑️ Preparation for defrosting
Compressor shutdown sequence
The most important stage is the correct one blackout. In two-compressor models Atlant, a single control unit or separate thermostats are often used, but power is supplied through one plug. You need to move the thermostats of both chambers to the “0” or “Off” position, if such a function is provided by the design.
After moving the regulators to the non-working position, wait 1-2 minutes. This is necessary to equalize the pressure in the system before shutting down completely. Then unplug the power cord from the outlet. It is strictly forbidden to pull the wire; hold only the plug body.
If your model is equipped with electronic control, the procedure may vary. In this case, you should use the power button on the control panel, holding it for several seconds until the indicators go off. Only after this can you remove the cord from the network. Electronic module It is sensitive to sudden surges, so a smooth shutdown is preferable.
What to do if the thermostat is jammed?
If the thermostat knob does not turn to position "0", do not make excessive efforts. Gently try to rock it from side to side. If the mechanical stop does not allow you to turn off the camera, simply unplug the refrigerator, skipping the adjustment step. The main thing is to stop the supply of electricity.
The process of removing ice and frost
After turning off, leave the freezer and refrigerator doors open. The natural melting process will take from 4 to 12 hours depending on the thickness of the ice and the room temperature. Do not try to immediately chip the ice with a knife or other sharp objects - this is the surest way to damage evaporator and lose the refrigerant.
You can use safe methods to speed up the process. For example, spraying warm (not hot!) water from a spray bottle onto an ice crust. It is also effective to place containers of hot water in the chamber, covered with a lid, so that the steam accelerates the melting. Change the water as it cools.
Water will flow into special grooves and then into the drainage hole. Make sure the condensate drain is not clogged with crumbs or debris. If water sits in the pan and does not drain, use a soft rubber bulb or a syringe without a needle to carefully pump out excess liquid.
| Defrost method | Time taken (min) | Risk of damage | Efficiency |
|---|---|---|---|
| Natural melting | 240-720 | Low | High |
| Warm water in a container | 60-120 | Low | Very high |
| Hair dryer (warm air) | 30-40 | Medium (plastic) | High |
| Mechanical (knife) | 10-20 | Critical | Average |
⚠️ Attention: Using a hair dryer is allowed only at the minimum temperature and from a distance of at least 30 cm. A directed stream of hot air can deform the plastic body of the freezer or damage the seals.
Cleaning internal surfaces and drainage
When all the ice has melted, it’s time for general cleaning. The internal surfaces of the chambers, shelves and drawers must be washed with a solution of mild household chemicals or soda. For plastic elements Atlant, a weak solution of baking soda (1 tablespoon per liter of water) is best suited, which perfectly removes odors.
Pay special attention to the drainage hole in the refrigerator compartment. It often becomes clogged with mucus or food debris, resulting in puddles under the vegetable drawers. You can clean it with a special soft brush included in the kit, or with a regular cotton swab.
After washing, thoroughly wipe all surfaces with a dry soft cloth. Moisture should not remain on the walls, since when you first turn it on, it will instantly turn into an ice crust, nullifying all your efforts. Allow the chambers to dry completely for 15-20 minutes with the doors open.
Starting the refrigerator after defrosting
Before turning on, make sure that all removable elements (shelves, grilles, drawers) are in place and completely dry. Insert the plug into the outlet. If your model has a separate power button on the body, press it. The thermostats in both chambers should be set to the middle position (usually this value is “2” or “3”).
Do not load food into the chambers immediately. Let the refrigerator run idle for at least 2-3 hours. This is necessary for the system to reach operating temperature and for the thermostat to automatically turn off the compressors. Loading warm products immediately after switching on will cause the motor to wear out.
Monitor the operation of the compressors in the first hours. They can be turned on one by one or simultaneously - this is normal for two-compressor systems. If you hear an unusual knock, hum or whistle, or if one of the compressors does not start at all, immediately turn off the device and contact service.
Frequent maintenance errors
One of the most common mistakes is the use of chemical solvents or abrasive sponges for cleaning. Aggressive chemistry can corrode the plastic and damage the antibacterial coating, if any. The surface of the evaporator The inside of the chamber is also very sensitive.
Another mistake is ignoring the regularity of defrosting. Many people wait until the layer of ice is as thick as a finger. This significantly increases energy consumption, since the ice acts as a heat insulator, preventing the food from cooling. The compressor is forced to work longer, which shortens its service life.
Also, users often forget to check the horizontal installation after moving the refrigerator back to the wall. If the unit is not level, the doors may not fit tightly, which will lead to constant entry of moist air and rapid accumulation of ice.
How long should the camera dry before turning on?
15-20 minutes of active drying with a towel and another 10-15 minutes just with the doors open are enough. The main thing is that there are no visible drops of water on the bottom and walls. The residual air humidity inside the chamber will be removed by the circulation system itself upon first start-up.
Is it possible to defrost only the freezer without touching the refrigerator compartment?
Technically, this is possible in two-compressor models, since the circuits are independent. However, to avoid the risk of condensation getting on operating components and to simplify cleaning, manufacturers recommend turning off the entire unit. This also makes it possible to carry out complete sanitization.
What to do if after defrosting the refrigerator does not freeze?
If after 3-4 hours of operation the temperature does not decrease, check whether the doors are tightly closed. If the problem persists for more than 6-8 hours, the circuit may have been damaged during cleaning or an electronic failure may have occurred. In this case, you need to call a specialist.
Do you need to wash the condenser at the back of the refrigerator?
Yes, it is useful to do this once a year. Dust on the black condenser grille (at the back or on the sides) impairs heat transfer. Carefully vacuum the grille or blow it with compressed air, after unplugging the appliance from the mains.
