Owners of two-compressor equipment are often faced with a dilemma: how to carry out scheduled maintenance of the unit without losing supplies of fresh food in the main compartment. Two-compressor refrigerator it is structurally different from single-circuit models in that each compartment has an independent cooling system. This unique advantage allows owners to service the freezer while leaving the refrigerator compartment in operating mode.
Many users mistakenly believe that to remove ice it is necessary to turn off the entire appliance. In fact, if you have a model Atlant with two motors, you can isolate processes. This saves time, since the products in the refrigerator compartment will not have time to heat up to critical temperatures during a short procedure. However, there are nuances that must be taken into account in order not to damage the equipment.
In this guide we will analyze in detail the algorithm of actions for models Atlantequipped with two compressors. You will learn how to defrost safely, what tools you will need and what you should absolutely not do. Compliance with the technology will extend the service life of the seals and the compressor.
Design features of two-compressor systems
The main feature that allows you to defrost only the freezer compartment lies in the engineering solution of the cooling system. Unlike older models with one motor, where the refrigerant circulates through a single circuit, two independent ones are installed here. One is responsible for low temperatures in the freezer, the second maintains the climate in the refrigerator compartment. compressor. One is responsible for low temperatures in the freezer, the second maintains the climate in the refrigerator compartment.
Each evaporator has its own thermostat or electronic sensor. This means that turning off one of the nodes does not affect the operation of the other. When you turn off the freezer, the refrigerator compartment compressor continues to operate as normal, maintaining the set temperature. It is this principle that underlies the possibility of partial defrosting.
What is the difference between No Frost and manual defrosting in two-compressor units?
In two-compressor Atlant models, a combination is often found: a refrigerator with a No Frost system (does not require defrosting) and a freezer with manual defrosting (requires removal of ice). Less common are models where both compartments require manual defrosting.
It is important to understand that even if there are two motors, the heat exchange between the chambers does not go away. The walls separating the compartments conduct temperature. Therefore, even if the refrigerator is working, prolonged opening of the freezer door or its full heating can provoke more active operation of the second compressor. Thermal insulation in such cases it works at the limit of its capabilities.
Preparation for the defrosting procedure
Before Before turning off the power, you need to properly prepare your food and workspace. Chaotic extraction of reserves will lead to a rapid increase in their temperature. Determine in advance which products can be temporarily transferred to the refrigerator compartment, and which are better left in thermal bags.
Prepare a place to collect water. Melt water can be dirty, so it is better to cover the floor in front of the refrigerator with rags or place wide containers. Do not use sharp objects to chip ice before starting the process - this may damage the evaporator evaporator.
- 🧊 Prepare basins or trays to catch the draining water so as not to flood the kitchen.
- 🔌 Find an outlet that can reach the power cord, or use an extension cord to convenience.
- 🧤 Prepare a soft rag and sponge to remove residual moisture from the walls of the chamber.
- 🌡️ Check that you have a thermometer to control the temperature of the food if necessary.
☑️ Ready for defrosting
Step-by-step instructions: how to turn off one chamber
The process of defrosting only the freezer compartment is technically simple, but requires consistency. The main rule: first turn off the power, then open the doors. If you open the door of a working freezer, the sensor will instantly react to the warm air, and the compressor will begin to wear out, trying to compensate for heat loss, which does not make sense at the time of defrosting.
First, find the temperature regulators. In models Atlant they can be mechanical (twists inside the camera) or electronic (display outside). For mechanical models, simply unscrew the freezer control to the “0” or “Off” position. In electronic models, you need to press the power button of the corresponding circuit.
⚠️ Attention: Never try to unplug the cord from the outlet by holding only the wire. This may cause the contacts inside the plug to break. Always grasp the plug body.
After the indicators have gone out and the compressor has stopped talking, you can open the doors. Remove all food. If the ice layer exceeds 5-7 mm, leave the doors open. Manufacturers do not recommend speeding up the process with a hair dryer or hot water, since sudden temperature changes are harmful to plastic and metal. Atlant not recommended, since sudden temperature changes are harmful to plastic and metal.
Comparison of Atlant models: mechanics and electronics
Different series of refrigerators Atlant may have different control systems. Understanding your model type will help you avoid disconnection errors. Below is a table showing the differences in the control of two-compressor models.
| Control type | Location of regulators | Shutdown indication | Features |
|---|---|---|---|
| Mechanical | Inside the chambers (twists) | Thermostat click, silence | Simplicity, reliability, no display |
| Electronic | On the outer door (display) | Indicator goes off, sound signal | Fine adjustment, child protection |
| Mixed | Refrigerator - fur, Freezer - electric. | Depends on the compartment | Found in older series |
In mechanical models everything is simpler: turn the knob counterclockwise all the way - and the camera is turned off. Electronic systems sometimes require you to hold the button for a few seconds to activate the shutdown mode. Control Panel can become locked, so be sure to unlock the buttons before attempting to shutdown.
If the compressor continues to hum or click after shutting down, do not panic. This could be the sound of refrigerant flowing or the operation of a second compressor. Make sure that you have turned off exactly the desired circuit by checking the indication or absence of cold after 15-20 minutes.
Cleaning and removing ice crust
After the main body of ice has melted and drained, a thin ice crust or dirt may remain on the walls of the chamber. To remove them, use a soft sponge soaked in a warm (not hot!) soda solution. Soda perfectly disinfects and removes odors without leaving a chemical taste.
It is strictly forbidden to use a knife, screwdriver or other sharp objects to chip ice. Aluminum evaporatorlocated behind the plastic panel or being the wall of the chamber, it is very easy to break through. Repairing a broken circuit is often not economically feasible and requires calling a technician with equipment for sealing and refilling with freon.
Wipe all surfaces thoroughly dry. The remaining moisture will turn back into ice when turned on, creating an unnecessary layer of insulation that will worsen heat transfer. Pay special attention to the corner joints and the door seal, where dirt often accumulates.
Starting the system after maintenance
When the camera is completely cleaned and wiped dry, you can start starting. First, download the products. You should not fill the freezer to capacity with warm food - this will create excess load. Spread the supplies evenly so that air can circulate.
Turn on the power to the freezer. If you have a mechanical model, turn the control to the operating position (usually number 3 or 4). For electronic models, press the power button. Please note that the second compressor (of the refrigerator compartment) may be running at this moment - this is normal.
⚠️ Attention: Do not load the freezer with a large amount of warm food immediately after turning it on. This can lead to prolonged operation of the compressor without stopping and spoilage of food in the refrigerator compartment due to heat exchange.
Allow the equipment to idle for at least 30-60 minutes before fully loading, if possible. This will allow the system to return to normal and stabilize the temperature. Complete cooling to the set values can take from 2 to 12 hours, depending on the ambient temperature in the kitchen.
Frequent errors and precautions
One of the common mistakes is ignoring the condition of the sealing rubber. While the chamber is open and empty, inspect seal. If it is dirty, wipe it with soapy water. If the rubber has cracks or has lost elasticity, the cold will escape, causing the compressor to work more often.
Another mistake is the use of chemicals with an aggressive odor (chlorine, ammonia) inside the chamber. Plastic easily absorbs odors, which are then transferred to products. Use only specialized products for refrigerators or proven soda.
- ❌ Do not pour boiling water on ice - the plastic can be deformed from high temperatures.
- ❌ Do not turn on the refrigerator immediately, if you washed it with water - let the electrics dry.
- ❌ Do not put hot pans next to the open refrigerator during defrosting.
Remember that frequent defrosting (more than once a year for systems with manual defrosting) is not necessary and even harmful. An ice crust of up to 3 mm is not critical for the operation of the compressor. Excessive zeal in care can lead to wear and tear on the mechanical parts of the door and the seal.
Is it possible to defrost a freezer if there are perishable foods in the refrigerator?
Yes, you can. Since the chambers are independent, the food in the refrigerator compartment will not be damaged. However, try not to keep the refrigerator door open too often during the process, so as not to disturb the temperature in the second compartment.
What to do if the refrigerator does not freeze after defrosting?
Wait 1-2 hours. The compressor needs time to build up pressure and reach operating mode. If after 3-4 hours there is no cold, but the compressor is running, check whether the door is tightly closed. If the compressor is silent, check the presence of electricity and the settings of the thermostat.
Do you need to wash the inside of the refrigerator every time it defrosts?
General washing with detergents is enough to do 1-2 times a year. Each time you defrost, it is enough to wipe the surfaces with a damp cloth to remove condensation and possible contaminants to prevent the growth of bacteria.
