Modern two-chamber refrigerators of the brand Atlantequipped with two independent compressors are deservedly popular due to their reliability and ability to keep food fresh for a long time. However, even the most advanced equipment requires regular maintenance, and a key step in maintenance is proper defrosting of the freezer. Many owners mistakenly believe that the presence of two compressors completely eliminates the need to turn off the device, but this is not so.
The growth of an ice crust on the evaporator or chamber walls inevitably occurs in models with a manual or drip defrosting system, and also requires periodic monitoring in the systems No Frost. Ignoring this process leads to increased energy consumption, decreased cooling efficiency and, ultimately, breakdown of expensive unit components. In this article, we will analyze in detail the algorithm of actions that will help you carry out the procedure safely and quickly.
Why do you need regular defrosting of two-compressor models
The main reason for the need for defrosting lies in the physical properties of water vapor contained in the air and products. Each time the door is opened, moist air enters the chamber, where, under the influence of low temperatures, it condenses and freezes on the coldest surfaces - usually the back wall or the evaporator. Ice deposit acts as a heat insulator, interfering with effective heat exchange between the evaporator and the internal volume of the refrigerator.
In models with two compressors, such as the popular series Atlant XM-4000 or XM-6000, each unit is responsible for its own temperature circuit. If the freezer becomes covered in ice, the compressor is forced to work longer and harder to maintain the set temperature. This leads to premature wear of the motor-compressor and increased energy bills.
In addition, excessive amounts of ice can mechanically damage the door seals or block the ventilation holes, which will disrupt air circulation. In systems with partial automatic defrosting, ice can block the drainage of melt water, causing it to leak out or form puddles inside the chamber.
⚠️ Attention: Ice thickness of more than 5-7 millimeters is already considered critical and requires immediate intervention. Further operation in this mode may lead to deformation of the plastic elements of the case.
Regular maintenance extends the life of your refrigeration equipment and guarantees the preservation of the taste of the products. The frozen layer of ice also reduces the usable volume of the freezer, which is especially noticeable in compact models.
Preparation for the defrosting procedure
Before starting any manipulations, it is necessary to properly prepare the workplace and the unit itself. The first step is to empty the freezer of food. If you plan to defrost only one chamber (which is theoretically possible in two-compressor models, but is not always recommended by manufacturers), food from the refrigerator compartment can be left, but a full service cycle usually involves stopping the entire device.
Food should be placed in a cool place or placed in thermal bags with ice so that they do not have time to defrost and spoil during the procedure. After this, you need to disconnect the refrigerator from the power supply. To do this, remove the plug from the socket - this is mandatory requirement safety that cannot be ignored under any circumstances.
- 🧊 Prepare in advance several terry towels or absorbent rags to collect water.
- 🪣 Find a wide basin or shallow tray that will fit under the freezer to catch any draining liquid.
- 🧹 Prepare a soft sponge and neutral detergent for subsequent cleaning of the internal surfaces.
It is important to ensure access to all shelves and drawers. Remove all removable elements: plastic containers, glass shelves, bottle racks. It is better to wash them separately in the sink with warm water and soap while the main defrosting process is underway.
☑️ Preparing for defrosting
Step-by-step instructions for defrosting a freezer
The process of defrosting refrigerators Atlant with two compressors is not much different from servicing other models, but has its own nuances associated with the design of the evaporator. After you have turned off the appliance and emptied the chambers, you need to open the doors of the freezer and refrigerator compartments. This will provide an influx of warm air and speed up the melting of the ice.
Under no circumstances try to speed up the process using a hairdryer, hot water pouring directly onto the ice, or sharp objects. A sharp temperature change can lead to cracking of the plastic or damage to the evaporator tubes, which will render the refrigerator inoperable. Natural defrosting is the safest method, although it takes time.
If there is a lot of ice, you can put a container with warm (not boiling water!) water inside the chamber, closed lid so that the heat from it accelerates the melting. Periodically wipe off any draining water with a rag to prevent it from getting on the floor or flowing under the cabinet.
⚠️ Attention: The use of knives, screwdrivers or scrapers to chip ice is strictly prohibited. One awkward movement can break through the thin wall of the evaporator, and repairs will cost more than a new refrigerator.
The duration of the process depends on the thickness of the ice layer and the temperature in the room. On average, it takes 3 to 6 hours for complete thawing. Do not close the doors tightly until the moisture and ice have completely disappeared.
Care for the No Frost and drip system
Model owners Atlant are often confused about the types of defrosting. Two-compressor models can be equipped with a system No Frost (in the freezer) and a drip system (in the refrigerator compartment), or a complete system No Frost. If you have a model with No Frost, then formally you do not need to unfreeze it “manually”, since this happens automatically. However, once every year or two it is recommended to carry out a complete defrost for hygienic cleaning and checking drainage.
In models with a drip system (crying evaporator) in the refrigerator compartment, water flows down a groove into the drainage hole. It may become clogged with crumbs or mold. After defrosting, be sure to check the cleanliness of the drainage channel. To clean it, you can use a special soft brush or a cotton swab.
| System type | Frequency of defrosting | Care features |
|---|---|---|
| No Frost (full) | 1 time a year (hygiene) | Drainage cleaning, washing |
| Drip + No Frost | 1-2 times a year | Checking the groove in the refrigerator compartment |
| Manual defrosting | When the ice layer is > 5 mm | Full defrosting, removing water |
After all the ice has melted, thoroughly wipe all surfaces with a dry cloth. Pay special attention to the corners of the chamber and the rubber seals on the door, where dirt and moisture often accumulate. The cleanliness of these elements ensures a tight fit of the door.
Why does it smell after defrosting?
An unpleasant odor after defrosting may appear due to stagnant water in the drain pan or the remains of old food. Thoroughly rinse all removable parts with a soda solution (1 tablespoon per liter of water) and wipe the inner walls. If the smell remains, put an activated carbon tablet inside.
Completing the process and first launch
When you are sure that there is no ice, all surfaces are dry and clean, you can begin assembly. Replace clean and dry shelves, drawers and containers. Make sure they are level and not blocking air flow or closing the door. Now you can add food, but it is better to do this gradually.
Plug in the refrigerator. Dual-compressor models Atlant may make different sounds when first started - this is normal as the refrigerant begins to circulate through the system. Let the device operate empty or with minimal load for 1-2 hours so that it reaches operating mode and stabilizes the temperature.
- ❄️ Check that the temperature controls are set to the middle position (usually this is value 3 or the "Normal" mark).
- 🔌 Make sure that the plug sits tightly in the socket and the wire is not pinched.
- 🚪 Check that the door is tightly sealed - it should close easily force and do not bounce.
Only after the refrigerator has gained cold, can you load the main volume of food. Sharp loading with warm products immediately after defrosting will cause the compressors to work with overload.
Typical errors and problems during defrosting
One of the most common mistakes is an attempt to speed up the process mechanically. As already mentioned, chipping ice with a knife is a direct path to expensive repairs. Another mistake is turning on the refrigerator ahead of time. If there is water left inside, it may freeze in the drainage system during the next cycle of operation, creating an ice plug.
Some users forget to check the drainage hole, which leads to water starting to flow under the refrigerator after defrosting. This happens because the channel is clogged with dirt or frozen. Also, you should not use aggressive chemicals to wash plastic, as they can damage the structure of the material and cause an unpleasant odor.
⚠️ Attention: If, after defrosting and turning on, the refrigerator makes loud knocks, whistles or does not freeze for 3-4 hours, immediately turn it off and contact the service center. Perhaps moisture has entered the system or the compressor has malfunctioned.
Ignoring regular maintenance leads to the fact that the refrigerator begins to consume up to 30% more electricity. Timely defrosting saves money and guarantees a long service life of the equipment.
How long does it take to defrost an Atlant refrigerator?
The defrosting time depends on the thickness of the ice and the temperature in the room. Typically the process takes from 3 to 6 hours. Do not try to artificially speed up the process, this may damage the equipment.
Is it necessary to defrost a refrigerator with a No Frost system?
The No Frost system involves automatic removal of moisture, but once every 1-2 years, complete defrosting is recommended for hygienic treatment and cleaning the drainage channels from dust and mold.
What to do if a smell appears after defrosting?
It is necessary to thoroughly rinse all surfaces with a solution of baking soda or vinegar. Check the drain hole for debris. Place an odor absorber (charcoal, special tablets) inside.
Is it possible to defrost only the freezer compartment?
In two-compressor models, it is technically possible to turn off only one compressor, but manufacturers recommend turning off the entire device for complete sanitization and checking the tightness of the circuits.
