Two-compressor refrigerator models Atlant are deservedly popular due to their reliability and the ability to independently control the temperature in different chambers. However, even the most modern equipment, be it a classic system with drip defrosting or an advanced one, requires periodic maintenance. Many owners mistakenly believe that the presence of two separate motors completely eliminates the need to manually remove ice, but this is not always the case. No Frost, requires periodic maintenance. Many owners mistakenly believe that having two separate motors completely eliminates the need to manually remove ice, but this is not always the case.
The process of thawing ice in units with two compressors has its own technical features, which are important to consider in order not to damage the cooling system. Incorrect actions can lead to failure thermostats or damage to the internal coating of the cameras. In this article, we will analyze in detail the algorithm of actions, the required time interval and nuances for various modifications of Belarusian equipment.
It is worth immediately noting that ignoring the need to clear ice leads to a thickening of the ice crust, which causes compressors to wear out. This not only increases energy consumption, but also reduces the life of expensive unit components. Therefore, knowing how to correctly carry out this procedure is a must-have skill for every owner.
⚠️ Attention: Before starting any manipulations, make sure that you have disconnected the device from the power supply. Working with electrical wiring with wet hands or the presence of water in the access area to the outlet is strictly prohibited by electrical safety rules.
Design features of two-compressor Atlant models
The main difference between equipment Atlant with two motors is the presence of two independent circuits refrigerant. One compressor is responsible for the freezer compartment, and the second for the refrigerator compartment. This allows you to set and maintain different temperature conditions independently of each other, which is impossible in single-circuit systems.
Such models often use a combined heat removal system. The freezer can be equipped with a system No Frost (or “Full No Frost” in top models), where the evaporator is hidden behind a plastic panel and is blown by a fan. At the same time, the refrigerator compartment can operate on the drip principle, where moisture flows down the back wall into a special groove.
The presence of two separate cooling zones means that when defrosting you may have to consider the state of both circuits. If ice has formed in only one compartment, it is theoretically possible to defrost only it, leaving the second in operating mode, although manufacturers often recommend turning off the entire unit for comprehensive sanitary treatment.
Understanding the design of your specific model is critically important. If you have installed Atlant with full No Frostthen the formation of a massive ice coat indicates a malfunction of the defrosting system, and not normal operation. In classic models, ice is a natural process of condensation of moisture from the air of food.
When manual defrosting is necessary: signs and timing
The frequency of the procedure directly depends on the type of cooling system installed and the intensity of use of the refrigerator. For models with a drip system, manufacturers recommend defrosting at least once every 3-4 months. However, the actual frequency may vary depending on operating conditions.
There are a number of clear signs indicating that you can no longer delay maintenance. Ignoring these signals may result in the door no longer closing tightly and the tightness of the circuit being broken.
- ❄️ The thickness of the ice layer on the walls or door of the freezer has exceeded 5 millimeters, which significantly reduces the usable volume.
- 💧 Periodically appearing on the floor under the refrigerator or on the shelves of the lower tier puddles of water that do not have time to evaporate through the drainage hole.
- 🔊 The compressors began to work almost without interruption, the humming became more intense, and the rest cycle practically disappeared.
- 🌡️ The temperature inside the chambers no longer corresponded to the set values, food began to deteriorate faster than usual or, conversely, to freeze in the refrigerator compartment.
If you notice that the rubber seal on the door has lost its elasticity or does not fit tightly in some places, this may also be a consequence of the pressure of expanded ice. In such cases, mechanical removal of ice becomes the only way to restore tightness.
⚠️ Attention: Do not wait until the ice crust turns into a monolithic block. Removing a thick layer of ice mechanically (with a knife or screwdriver) will most likely lead to breakdown of the evaporator, which is a complex and expensive repair.
Preparation for the procedure: necessary tools and actions
Quality preparation takes less time than defrosting itself, but it depends on it process safety and safety of your property. Collect everything you need in advance so as not to run around the apartment with wet rags in your hands.
First of all, you need to empty the cells of food. If it’s winter outside, you can take perishable goods out to the balcony, having previously packed them. In the warm season, use thermal bags or ask your neighbors to temporarily place some of the supplies in their refrigerator.
☑️ Checklist for preparing for defrosting
To collect melt water you will need wide containers with low sides that can be placed under the drain, and a large number of well-absorbing rags. It is also a good idea to prepare a soft plastic scraper (often included) or a regular wooden spatula to speed up the process.
Don't forget to shut off the water supply if your model Atlant is equipped with a dispenser or water supply system. Although dual-compressor models rarely have such options, double-checking the technical documentation will not be superfluous. Also remove all removable shelves, drawers and containers - it is better to wash them separately in warm water with detergent.
Step-by-step instructions: how to defrost a refrigerator correctly
The defrosting process itself does not require complex engineering knowledge, but requires patience and following a sequence of actions. The main rule is not to rush things with aggressive methods that can damage the plastic or evaporator tubes.
After you have unplugged the device and removed the food, open the doors of both chambers wide. This will provide an influx of warm air and start the natural process of ice melting. If your freezer has a “Super Freeze” or similar function, make sure it is turned off.
To speed up the process, you can use safe methods that do not involve the use of sharp objects or boiling water. For example, place containers with hot water inside the chambers (but not boiling water, so as not to deform the plastic). Close the doors for 10–15 minutes, then repeat the procedure.
| Stage | Action | Execution time |
|---|---|---|
| 1. Disconnection | Removing the plug from the socket, opening the doors | 2 minutes |
| 2. Natural melting | Waiting for ice to soften without intervention | 3–5 hours |
| 3. Removing ice | Carefully removing thawed layers with a soft spatula | 30 minutes |
| 4. Water removal | Wiping moisture from the walls and bottom of the chambers | 20 minutes |
| 5. Startup | Plugging in and loading with products | 1 hour after drying |
When most of the ice has disappeared, thoroughly wipe all surfaces with a dry soft cloth. Pay special attention to the drainage hole in the refrigerator compartment - it often becomes clogged with food debris or dirt. You can clean it using a special brush or soft wire wrapped in cotton wool.
Can a hair dryer be used for defrosting?
Using a hair dryer is only permissible in cold blowing mode or at minimum temperature from a long distance. A hot stream of air can locally overheat the plastic, causing it to deform or crack, and also damage the rubber seals. It’s not worth risking the integrity of the camera to save 20 minutes.
Typical mistakes and what you should absolutely not do
The desire to quickly complete an unpleasant procedure often leads to fatal mistakes. Statistics from service centers show that a significant portion of refrigerator breakdowns Atlant occur precisely through the fault of users during defrosting.
The most common and dangerous mistake is the use of knives, forks, screwdrivers or other sharp metal objects to chip ice. The inner walls of the chambers contain tubes evaporatorwhich are located very close to the surface of the plastic. One awkward movement will lead to a breakdown and instant release of the refrigerant.
- 🚫 Do not pour boiling water directly onto the ice block - a sudden temperature change can cause cracks in the plastic case or damage the glass shelves.
- 🚫 Do not turn on the refrigerator, until it is completely dry - moisture that gets on the electrical contacts or in the insulation of the wires will cause a short circuit.
- 🚫 Do not use aggressive chemicals (bleach, acetone, solvents) to wash the internal chambers - this can destroy the plastic and leave toxic traces that are dangerous for the products.
⚠️ Attention: If you accidentally if the evaporator tube is damaged and you hear the hissing of escaping gas, immediately ventilate the room and call a technician. It is impossible to repair such a hole on your own; professional sealing and refilling with freon is required.
It is also a mistake to load products into chambers that have not yet cooled down. If you turn on an empty refrigerator, let it run for at least an hour (preferably two) to reach operating temperature. Loading warm products will cause both compressors to work in overload mode, which will negatively affect their service life.
Care after defrosting and preventing ice formation
After successfully completing the procedure and turning on the unit, it is important to properly organize the space inside in order to minimize the rate of re-formation of ice. Cleanliness and proper air circulation are your main allies.
Regularly check the tightness of the doors. If the seal is dirty, wipe it with a weak soda solution or a special rubber cleaner. You can also lubricate the seal with silicone grease or glycerin so that it does not dry out and adheres elastically to the body.
Do not put hot or warm foods directly into the refrigerator. Let them cool to room temperature. The evaporation of moisture from hot soup or compote will instantly turn into frost on the cold walls, starting a cycle of ice growth.
Also make sure that the drainage hole always remains clean. If the water stops draining, it will freeze and create a plug, disrupting the operation of the entire condensate drainage system. Preventative cleaning of the groove once a month will extend the life of your Atlanta.
How long does it take on average to defrost a two-compressor refrigerator?
The full defrosting cycle, including preparation, natural melting of ice, water removal and primary cooling of empty chambers, usually takes from 4 to 6 hours. The time may vary depending on the thickness of the ice layer and the temperature in the room.
Is it necessary to defrost both chambers at the same time if they are independent?
Technically, thanks to two compressors, it is possible to defrost the chambers in turn, turning off only one zone (if the design allows local shutdown). However, manufacturers recommend turning off the entire unit to carry out complete sanitization and prevent temperature imbalances.
What to do if the refrigerator does not freeze after defrosting?
Let the device run idle (without food) for 2-3 hours. If the temperature does not decrease, check whether the doors are tightly closed and whether the thermostat setting is lost. If the problem persists, diagnostics by a specialist will be required.
Is it possible to wash the inside of the refrigerator with soap and water?
Yes, you can and should. Use warm water with mild detergent or baking soda. Thoroughly rinse the surfaces with clean water and wipe dry before turning on to eliminate the appearance of foreign odors.
