Modern two-chamber refrigerators of the Belarusian brand Atlant are deservedly popular due to their reliability and functionality. However, even the most advanced models, especially those equipped with a No Frost or Low Frostsystem, require user intervention over time to maintain effective operation. The formation of an ice crust on the walls of the chamber is a natural physical process that cannot be ignored, since it directly affects the energy consumption and service life of the compressor.
Owners often wonder how often this procedure needs to be carried out and whether it is possible to speed up the process without harming the equipment. Unlike old single-chamber models, which required a complete shutdown for a day, modern units allow you to optimize this process. The main thing is to understand the principle of operation of the evaporator and not try to speed things up by mechanical action, which is the most common mistake.
Below we will analyze in detail the algorithm of actions that will help you safely get rid of ice, maintaining the tightness of the seals and the integrity of the cooling tubes. Compliance with these simple rules will ensure that your Atlant refrigerator will serve for many years without expensive repairs.
Causes of ice formation and the need for defrosting
The accumulation of a snow coat occurs due to the moisture contained in the air that enters inside the chamber when the door is opened. Moisture condenses on cold walls and freezes. In systems Low Frost, which are often installed in models Atlant XM-4425 or XM-4525, this process is slowed down, but not completely eliminated. If the ice layer exceeds 5-7 millimeters, the thermal conductivity of the walls is disrupted, and the compressor is forced to work in increased mode.
⚠️ Attention: Ignoring the growth of ice more than 10 mm thick can lead to overheating of the compressor motor and its premature failure, as heat exchange is disrupted.
In addition In addition, ice build-ups can mechanically damage products by pinching packaging and reduce the usable volume of the freezer compartment. In some cases, a dense ice crust blocks the flow of water into the drainage hole, which leads to the appearance of puddles on the kitchen floor. Regular defrosting (defrosting) is necessary to maintain hygiene and cooling efficiency.
It is worth noting that the frequency of defrosting depends on the frequency of door opening and room humidity. In summer, when there is more moisture in the air, this process may be required more often. If you notice that the refrigerator begins to hum louder than usual or does not turn off longer, this is a sure signal that it is time to do maintenance.
Preparing for the defrosting process
Before starting any manipulations, you must empty the freezer of food. If you plan to defrost quickly, food can be temporarily placed in a bowl of ice or wrapped in thick blankets to slow down the melting. For a longer procedure, it is better to use thermal bags or ask your neighbors to borrow some of the supplies for a while.
It is important to prepare equipment in advance so that the water flowing down when the ice melts does not flood the kitchen. You will need:
- 🧽 Absorbent rags or towels for the floor.
- 🥣 A container with a wide neck for collecting water (if drainage is not provided structurally).
- 🪣 Plastic spatula or spatula (only made of soft material!).
- 🧴 Cleaning agent for internal surfaces (soda or a special product).
After the food has been removed, the refrigerator must be disconnected from the power supply. Unplug the plug from the socket or turn off the circuit breaker on the panel. Under no circumstances try to clean the unit while it is connected to the network, even if you are just wiping the shelves - this is a question of electrical safety.
☑️ Preparation checklist
Natural defrosting: a safe method
The most gentle way for your Atlant refrigerator is the natural melting of ice. Leave the freezer and refrigerator doors open. The process will take from 4 to 10 hours depending on the amount of ice and the room temperature. This method eliminates the risk of damage to the evaporator and deformation of the plastic.
While waiting, you can start cleaning the external surfaces and radiator grilles at the back of the unit. Dust accumulating there impairs heat transfer, forcing the compressor to work harder. Carefully vacuum the back wall, being careful not to damage the thin condenser tubes.
When the ice has completely melted, carefully wipe the inside walls with a dry rag. Pay special attention to the grooves and rubber seals. Moisture remaining in the folds of rubber can cause mold or unpleasant odors in the future. Make sure that the drainage hole is free of debris.
⚠️ Attention: Do not use hot water to accelerate the melting of ice inside the chamber - a sudden temperature change can cause microcracks in the plastic case or damage the evaporator tubes.
Accelerated defrosting: acceptable and prohibited methods
If you wait for time a few hours away, you can resort to accelerated methods, but this must be done with extreme caution. It is strictly forbidden to use sharp objects (knives, screwdrivers, scrapers) to chip ice. The plastic in modern models Atlant is quite fragile, and the evaporator tubes are located very close to the wall - one careless blow will lead to a freon leak and expensive repairs.
It is permissible to use a hair dryer, but only in the mode of supplying warm (not hot!) air and at a distance of at least 30-40 cm from the surface. Direct the air flow evenly, without lingering at one point for too long, so as not to melt the plastic. You can also place bowls of warm water inside the chamber, closing the door for 10-15 minutes, then repeat the procedure.
Below is a table comparing defrosting methods:
| Method | Time spent | Safety for equipment | Recommended frequency |
|---|---|---|---|
| Natural melting | 4-10 hours | 100% safe | As needed |
| Hair dryer (warm air) | 30-60 minutes | Medium (risk of plastic overheating) | In emergencies |
| Bowls with warm water | 1-2 hours | High | With average ice |
| Mechanical chipping | 10-20 minutes | Critical danger | Prohibited |
Why can't you use a knife?
Using a knife to chip ice is the most common reason for refrigerator failures. The blade easily penetrates the thin wall of the evaporator where the refrigerant circulates. Repairing such a hole requires calling a technician, evacuation of the system and refilling with freon, which can cost up to 50% of the price of a new refrigerator.
Care for the No Frost and Low Frost system
Many users mistakenly believe that the systems No Frost (in the refrigerator compartment) and Low Frost (in the freezer) do not require defrosting at all. This is not entirely true. Although the automation periodically removes the main condensate, the moisture does not completely disappear. It settles in hard-to-reach places, mixes with food particles and turns into an ice porridge, which hardens over time.
In models Atlant with a system Low Frost (for example, series XM-6025), the evaporator is hidden behind the back wall, but ice can build up on the wall and door itself. It is also recommended to defrost such equipment once every 6-8 months. This will help eliminate unpleasant odors and restore the efficiency of the fans.
If you notice that ice is constantly forming in the No Frost chamber, check the tightness of the door. The seal may have become dirty or deformed, allowing warm air to pass through. Also, the cause may be a clogged drainage channel that drains melt water into the evaporator.
Completion of the process and first start-up
After you have removed all the ice, washed and, most importantly, wiped the internal surfaces dry, you can start launching. Leave the doors open for another 15-20 minutes so that any remaining moisture completely evaporates and the temperature inside becomes equal to room temperature. A sudden start of the compressor in a still humid environment is undesirable.
Plug in the refrigerator. In the first 30-40 minutes, do not load the chamber with food. Allow the unit to reach operating temperature. Indicators on the control panel (if any) or the characteristic sound of a running compressor will indicate that the process has begun. In models with electronic control, you may need to reset the settings or activate the mode Super Freeze.
When the temperature stabilizes (usually after 2-3 hours), you can carefully add food. Do not overload the freezer with a large amount of warm food at once - this will create unnecessary load. Distribute supplies evenly, leaving space for air circulation between bags.
⚠️ Attention: Specifications and location of controls may vary depending on the specific series of the refrigerator. Always check the official user manual (operation manual) that comes with your device.
Frequently asked questions and troubleshooting
Is it possible not to unplug the refrigerator from the outlet when defrosting?
Absolutely not. Defrosting is only possible when the power is completely turned off. A running compressor will try to compensate for the heat from the melting ice, working to wear out, and the water can cause a short circuit in the electrical circuit.
What to do if the refrigerator does not freeze after defrosting?
Let it run empty for 4-5 hours. If the cold does not appear, check whether the hose is pinched or the thermostat is moved. If the problem persists, the circuit may have been damaged during cleaning or the start relay has burned out.
How often does Atlant with Low Frost need to be defrosted?
The optimal frequency for Low Frost systems is once a year or when a layer of frost becomes visually noticeable (more than 2-3 mm). Complete defrosting is also useful for sanitizing.
Can a steam cleaner be used for defrosting?
Using a steam cleaner is risky due to the high temperature of the steam and the pressure of the jet. Moisture can get into electrical components or damage the plastic. It is better to use proven methods with warm water.
