Owners of Belarusian-made equipment often wonder how to properly defrost a two-compressor Atlant refrigerator without damaging the complex cooling system. Despite the fact that modern models are equipped with No Frost systems, many units, especially earlier series or the budget segment, require manual defrosting a freezer. Ignoring this procedure can lead to a decrease in the efficiency of the compressor and even damage to the evaporator.
The two-compressor system is not just a marketing name, but a technical feature that allows you to independently regulate the temperature in the refrigerator and freezer compartments. This means that the process of thawing ice here has its own nuances that distinguish it from the defrosting of single-compressor analogues. In this material, we will analyze in detail the algorithm of actions, time intervals and critical points that will ensure a long life for your device.
Before starting any manipulations, you need to understand that the dual-circuit temperature control system requires careful attention to each node. Automatic defrosting in the refrigerator compartment does not mean that the freezer is cleared of ice by itself. The accumulation of a snow coat more than 5-7 millimeters thick is already considered critical and requires user intervention to restore heat exchange.
Preparation for the defrosting procedure
The process should begin by preparing the workspace and the unit itself. The first step is to disconnect food devices from the electrical network. In two-compressor models, a separate motor-compressor is responsible for the operation of the freezer, which must also be de-energized. Do not try to pull out the plug with wet hands if the water in the chamber has already begun to melt - this violates safety precautions.
Next, you should empty the chambers of food. Since we are talking about a two-compressor system, you can theoretically leave the refrigerator compartment running if the model allows independent control, but for high-quality defrosting of the freezer it is better to turn off the entire device. This will prevent temperature changes and condensation on the inner walls of the adjacent chamber.
Prepare a container for collecting melt water and absorbent materials. Water will drain by gravity if the tray design allows it, or drip onto the floor if the drainage hole is clogged or missing. Lay old towels or rags on the floor in front of the refrigerator in advance.
- 🧊 Remove all shelves, drawers and trays from the freezer - it is better to wash them separately in warm water.
- 🔌 Make sure that the power cord is completely unplugged from the outlet, and not just turned off with the toggle switch on case.
- 🧹 Prepare a soft rag and a plastic scraper to remove large pieces of ice.
- 💧 Prepare in advance a basin or tray that will fit under the freezer to collect the bulk of the water.
⚠️ Attention: It is strictly forbidden to use sharp metal objects (knives, chisels) to chip ice. In two-compressor Atlant refrigerators, the evaporator is often located directly behind the back wall, and its damage will lead to freon leakage and expensive repairs.
Algorithm of actions: step-by-step instructions
After all the preparatory stages are completed, you can proceed directly to defrosting. Open the freezer door and leave it open. In two-compressor models, air will circulate differently than in single-compressor models, so it is important to ensure maximum flow of warm air from the room to the evaporator.
If the ice layer is very thick, you can carefully collect large layers of ice with gloved hands or a plastic scraper, but only those pieces that have already moved away from the walls. Don't use force. The bulk of the ice should melt on its own when exposed to room temperature. Accelerate this process with hair dryers or heating pads with boiling water not recommendedas a sharp temperature change can cause microcracks in the plastic or deformation of the seals.
During the melting process, watch where the water flows. In some Atlant models with two compressors, the drainage system of the freezer may be less efficient than that of the refrigerator. You may have to periodically scoop out the water from the bottom tray.
☑️ Checklist for proper defrosting
After the ice has completely melted, it is necessary to thoroughly wipe the inner surface of the chambers. Use a weak soda solution or a special refrigerator cleaner. It is important to remove not only visible dirt, but also mucus that may have formed on the walls.
Defrosting time and influencing factors
The duration of the procedure directly depends on the thickness of the ice crust and the temperature in the room. Dual-compressor refrigerators often have larger freezer compartments and may have thicker insulation, which increases defrosting time. On average, a full cycle takes from 3 to 6 hours.
Several factors influence the speed of the process. Firstly, this is the initial temperature of the evaporator. Secondly, the air humidity in the room - in a dry room the ice melts more slowly, but less condensation forms. Thirdly, how densely the chamber was filled with products before turning off (although we had already taken out the products, the plastic itself and the shelves can retain cold).
Below is a table showing the approximate defrosting time depending on conditions:
| Ice thickness | Temperature in the room | Approximate time | Recommendations |
|---|---|---|---|
| 3-5 mm | +22...+24°C | 2-3 hours | Natural melting is sufficient |
| 5-10 mm | +20...+22°C | 4-5 hours | Water control required |
| More than 10 mm | +18...+20°C | 6-8 hours | It is better to leave overnight |
| Any | Below +18°C | 8+ hours | The time increases significantly |
Do not try to artificially speed up the process by placing a pot of boiling water inside. Steam can damage the electrical contacts of the thermostat or sensors located inside the chamber. Natural defrosting is the safest method for the compressor and evaporator.
Why can’t you turn on the refrigerator until it is dry?
Residual moisture in hard-to-reach places when the compressor is turned on may cause a short circuit or corrosion of the contacts. In addition, sudden cooling of wet walls will lead to the instantaneous formation of new ice, which will negate all efforts.
Caring for a two-compressor system after defrosting
When the ice has completely melted and the internal surfaces have been washed and wiped dry, do not rush to immediately load the products. Let the refrigerator stand with the doors open for another 30-40 minutes. This is necessary so that the remaining smell of the detergent disappears and the moisture completely disappears from the pores of the plastic.
Plug in the device. In two-compressor Atlant models, you can hear how one compressor starts first, and after a while the second. This is normal operation electronic control unitwhich sequentially runs circuits to reduce the peak load on the network.
Let the refrigerator idle for at least 1-2 hours before loading food. During this time, the system will reach the required temperature, and the sensors will record readiness for operation. Only after this can you place the products, distributing them evenly so as not to block the ventilation holes.
- 🧼 Wipe the rubber door seals with glycerin or special lubricant - this will prolong their elasticity.
- 🌬️ Check the ventilation grilles on the rear wall of the case - they must be clean for effective heat exchange.
- 🌡️ Make sure the thermostat is set to the correct position (usually the average value).
⚠️ Attention: If the refrigerator makes an unusual noise or knocking noise after turning on, do not panic immediately. A dual-compressor system may be louder than a single-compressor system due to the design of the motors. However, if the sound resembles a metallic clang, the device should be turned off and called a technician.
Frequent errors when defrosting
Many users make mistakes that shorten the life of the equipment. One of the most common is an attempt to defrost the refrigerator without unplugging it from the mains, simply by setting the temperature regulator to minimum. In two-compressor models, this is ineffective, since the operating cycles of the motors are independent, and the ice will melt for too long, consuming electricity.
Another mistake is the use of aggressive chemicals for washing. Abrasive powders scratch the plastic, and dirt and bacteria then accumulate in microcracks. Only neutral detergents are suitable for the plastic of Atlant cameras.
It is also a mistake to ignore the drainage hole. If there is water left inside after defrosting, it means the channel is clogged. It must be carefully cleaned with a special brush or soft wire to ensure the removal of condensation in the future.
Prevention of ice formation
In order to reduce the need for defrosting, you should follow the operating rules. First of all, make sure that the doors are closed tightly. If the seal is worn out or the door is skewed, moist air will constantly flow in and condense on the walls.
Check the condition of the food regularly. Open containers with liquids (soups, compotes) must be closed with lids. Evaporation of moisture from food is one of the main reasons for the formation of a “snow coat” even in a working refrigerator.
Do not forget that a two-compressor system is more sensitive to overloads. Don't overcrowd the freezer, leave room for cold air to circulate. This will ensure uniform cooling and reduce the load on the evaporator.
Questions and answers (FAQ)
Is it possible to defrost an Atlant refrigerator hair dryer?
Using a hair dryer is possible, but with great caution. Direct the flow of warm (not hot!) air only onto the ice, avoiding contact with plastic parts and rubber seals, which can be deformed by high temperatures. It’s better to use the natural method.
Why doesn’t the refrigerator freeze for a long time after defrosting?
The two-compressor system takes time to reach the operating mode. If you load food too early or when it's warm, the compressor will wear out. Also, the reason may be incorrect installation of the thermostat or loose closing of the door.
Do you need to lubricate door hinges after defrosting?
Yes, this is a good practice. After washing and drying, you can lubricate the door hinges with a small amount of machine oil or silicone grease to prevent squeaking and corrosion, as moisture could get into the mechanisms.
What to do if the water does not drain into the drain?
Most likely, the drain hole is frozen or clogged with debris. Take a thin wire or a special brush and carefully clean the channel. You can also pour a little warm (not hot!) water into it with a syringe without a needle to melt the ice plug.
