Modern Belarusian refrigerators production Atlant are famous for their reliability, but even the most advanced equipment requires periodic maintenance. Owners often wonder whether their unit needs manual defrosting or whether the automation handles it itself. The answer lies in understanding the operating principle of your specific model, since maintenance approaches differ radically depending on the type of cooling system.
Incorrect operation or ignoring equipment signals can lead to a decrease in the efficiency of the compressor, an increase in energy consumption and even failure of important components. Ice coat on the walls is not just a cosmetic defect, but a sign of a heat transfer disorder that cannot be ignored. Understanding exactly how thawing occurs in your case will help extend the service life of the device and preserve the freshness of the products.
In this article we will analyze in detail the mechanics of thawing processes for different models, point out hidden nuances that the instructions are silent about, and give a clear algorithm of actions. You will find out why complete thawing of ice takes at least 24 hourseven if visually it seems that the water has already stopped dripping, and what mistakes users most often make when trying to speed up this process.
Principles of operation of Atlant cooling systems
All refrigerators Atlant can be divided into two large groups according to the type of defrosting: models with a manual system and units equipped with a system No Frost or Frost Free. In classic models that use a drip system, moisture from the air settles on the back wall of the freezer, turning into frost. Periodically, the compressor turns off, and this frost melts, flowing into a special pan, from where it evaporates. However, in the freezer compartment of such refrigerators, the ice does not go anywhere and requires manual intervention.
Models with the system No Frost work differently. In them, air circulation occurs forcibly through a hidden evaporator. Thanks to this, moisture does not settle on the products and chamber walls, but is frozen on a hidden heat exchanger. Such units are installed Defrosting heating element, a timer and a thermostat, which automatically start the defrosting process several times a day. The user may not have to deal with the need to break ice manually for years, since the system does it autonomously.
Despite the presence of automation, even in systems No Frost it is recommended to carry out preventive defrosting. This is necessary in order to remove odors, disinfect internal surfaces and check the condition of the seals. In addition, dust and microscopic ice particles can accumulate over time in hard-to-reach places of the drainage system, which the automation does not always have time to eliminate. Regular complete shutdown of the equipment allows the system to “rest” and reset accumulated errors in the operation of the sensors.
⚠️ Attention: In models with the system No Frost it is strictly forbidden to use sharp objects to remove ice from visible parts of the evaporator if you reached them during disassembly. Damage to the evaporator tubes will lead to freon leakage and costly repairs.
How to understand what kind of system you have?
If on the back wall of the refrigerator you see a plastic panel with slots or holes, and there is no frost in the freezer, you have No Frost. If the back wall of the refrigerator is metal and covered with frost, and ice builds up in the freezer, this is a drip system with manual defrosting.
When it is necessary to defrost the refrigerator manually
It is not difficult to determine the moment when the equipment needs your help if you carefully monitor its condition. In models with manual defrosting, the signal is the thickness of the ice cover. As soon as the layer of frost or ice on the walls of the freezer reaches 5-7 millimeters, the efficiency decreases. The compressor is forced to work longer and harder to maintain the set temperature, which leads to overload of the engine.
There are a number of signs indicating the need for urgent defrosting, regardless of the declared type of system:
- ❄️ A noticeable decrease in cooling capacity: food in the refrigerator begins to deteriorate faster, and “porridge” appears in the freezer instead hard ice.
- 🔊 Increased noise during operation: the humming becomes longer, and the compressor cycles become more frequent.
- 💧 The appearance of puddles around the refrigerator or inside the chambers, which may indicate a clogged drainage hole.
- 🧊 Visual narrowing of the usable volume due to frozen blocks of ice, preventing the drawers from closing.
The frequency of defrosting depends on the operating conditions. If you frequently open the door, load warm foods, or have high humidity in the room, ice will build up faster. On average, for refrigerators Atlant with a manual system, it is recommended to carry out the procedure 1-2 times a year. For systems No Frost a preventive shutdown once a year is sufficient for hygienic cleaning, if no emergency situations have arisen.
Ignoring these symptoms leads to the fact that the ice shell blocks normal air circulation or contact of the thermostat with the chamber. As a result, the temperature sensor “does not see” the real cold and does not give a command to turn off the compressor. This is a direct path to a breakdown of the compressor motor or failure of the start relay.
Preparation for the defrosting procedure
High-quality defrosting is impossible without proper preparation. Before unplugging the power cord, you must empty the chambers of food. Take care in advance about where to put frozen supplies: you can use thermal bags, take the food out to the balcony (in winter) or put it in a nearby refrigerator. It is better to transfer the products from the main chamber to a cool place or temporarily use them for cooking.
After emptying the shelves and drawers, it is necessary to remove all removable elements: glass shelves, plastic containers, grilles, egg trays and ice trays. They should be washed separately with warm water and a mild detergent. This is the ideal time to check the integrity of the seals and clean them of dirt, as adhered dirt will disrupt the seal of the chamber.
Now you can proceed to turning off the power supply. Remove the plug from the outlet. If the outlet is located in a hard-to-reach place, you can use a surge protector with a power off button, but the best option is to physically disconnect from the network. Make sure the temperature control is set to “0” or “Off” before turning off to avoid a power surge when you turn it back on.
☑️ Preparation checklist
It is important to prepare the space around the refrigerator. Cover the floor with absorbent cloth or towels, as if a large amount of ice melts, water may flow over the edge of the tray and end up on the floor. Prepare several containers with warm (not hot!) water and sponges in advance to speed up the process if you decide to use the active defrosting method.
Step-by-step defrosting process
The safest and most correct way to defrost a refrigerator Atlant is natural thawing with the doors open. This method takes longer, but ensures that there is no thermal shock to the plastic parts, evaporator tubes and compressor. Just leave the doors open and wait. Depending on the thickness of the ice and the temperature in the room, the process can take from 10 to 24 hours.
If time is running out, you can use the accelerated method, but with extreme caution. Pour warm water into the containers (about 40-50°C) and place them on the shelves inside the chambers. Close the doors for 15-20 minutes. Warm evaporation will speed up the melting of ice. Change the water as it cools. You can also use a hairdryer, but you need to direct the stream of warm air strictly at the ice crust, without staying long in one place on the plastic parts to avoid their deformation.
During the melting process, keep an eye on the drainage hole, which is usually located at the bottom of the back wall of the refrigerator compartment. If it is clogged, water will drain onto the floor or into the bottom drawer. You can clean the hole using a special flexible brush or soft wire wrapped in cotton wool. After cleaning, rinse the channel with a small amount of warm water from a syringe or syringe.
| Defrosting method | Execution time | Safety for equipment | Recommendation |
|---|---|---|---|
| Natural | 12-24 hours | High | Recommended by the manufacturer |
| Warm containers | 3-5 hours | Medium | Acceptable with temperature control |
| Hair dryer (warm air) | 1-2 hours | Low (risk of overheating) | Only for experienced users |
| Hot water/Knife | 30 min | Critical | Prohibited |
When all the ice has melted, thoroughly wipe all surfaces with a soft cloth soaked in a weak soda solution or a special refrigerator cleaner. This will remove any remaining grease and bacteria. After wet cleaning, be sure to wipe the camera dry. Leave the doors open for another 30-60 minutes to completely evaporate the moisture and remove the smell of the detergent.
⚠️ Attention: Never use knives, screwdrivers, axes or other sharp metal objects to chip ice. One awkward movement can puncture the thin evaporator tube, through which the refrigerant will instantly escape. Repairs in this case will be difficult and expensive.
Typical mistakes when defrosting
One of the most common mistakes is the desire to speed up the process at any cost. Users pour boiling water, use hair dryers at maximum temperatures, or pick at the ice with a knife. Thermal shock can lead to cracks in the plastic housing of the chambers, deformation of the seals, and even failure of the soldering of the evaporator tubes. Plastic becomes brittle in the cold, and a sharp temperature change is detrimental to it.
Another mistake is turning on the refrigerator immediately after the water has stopped dripping. Moisture may remain inside porous materials, insulation and hidden cavities. If you turn on the compressor too early, residual water may freeze in parts that should be dry or cause an electrical short circuit. In addition, the compressor needs time for the oil, which could escape into the circuit during tilting or vibration, to flow back into the crankcase.
People often forget about cleaning the outside of the refrigerator, especially the condenser grille on the back wall. Dust and pet hair, accumulating there for years, create a “thermal insulating” layer. The compressor overheats because it cannot efficiently release heat to the environment. This leads to increased energy consumption and a reduction in the service life of the motor.
Some users immediately fill the chambers with warm food after defrosting. This creates a colossal load on the system. The refrigerator takes time to reach operating temperature when empty. Products should be loaded gradually, in small portions, giving the equipment the opportunity to cope with the heat.
Completing the procedure and first start-up
After you have made sure that the chambers are completely dry and there are no ice plugs in the drainage, you can prepare for start-up. Place the refrigerator in place, maintaining clearances from walls and furniture for normal ventilation. Insert the plug into the outlet. Make sure that the temperature regulator is in the middle position (usually this is division 2 or 3 out of 5, or temperature +4...+5°C).
Turn on the device and leave it to work without load (without food) for 2-4 hours. During this time, it should reach operating mode. You will hear the compressor turn on and off. This is a signal that the thermostat is working and the temperature has been reached. Only after this can you gradually load the products.
Pay attention to the operation of the fans in the models No Frost. After switching on, they may not start immediately, but after a few minutes. This is fine. If you hear extraneous knocking, grinding or humming noises that were not there before, it is possible that something got into the fan during defrosting or the tray has moved.
⚠️ Attention: Technical characteristics and operating requirements may vary slightly depending on the specific series and year of manufacture of your refrigerator. Atlant. Always check the official instructions (passport) attached to your model, especially in the sections on electrical safety and refrigerant types.
What to do if the refrigerator does not freeze after defrosting?
If more than 6 hours have passed since turning on, and there is no cold, check whether the light is on and whether the fan is working. Contact oxidation or electronics failure may have occurred. In this case, diagnostics by a specialist is required.
Frequently asked questions (FAQ)
Is it possible to defrost the Atlant refrigerator in winter by placing it on the balcony?
It is strictly not recommended to take the refrigerator out into the cold to defrost. Sudden temperature changes can damage plastic and seals. In addition, the oil in the compressor thickens in cold weather, and if you turn on the refrigerator immediately after it is warm, it may break down. Defrost appliances only at room temperature.
How long can you not turn on the refrigerator after defrosting?
The minimum waiting time before turning it on is 2 hours after the ice has completely melted and the surfaces have dried. This is necessary to evaporate moisture from hard-to-reach places and drain compressor oil. The optimal time is 4-6 hours.
Why did an unpleasant smell appear in the refrigerator after defrosting?
Most often it is the smell of stagnant water in the drain pan or channel that has not been washed. The odor can also be caused by food debris trapped under the seals. It is necessary to thoroughly rinse the drainage system with a solution of soda or citric acid and wipe all hidden cavities.
Is it necessary to defrost a No Frost refrigerator if ice is not visible?
Yes, preventive defrosting and washing once a year are necessary even for systems No Frost. This is necessary for hygiene, removing bacteria, mold and checking the condition of fans and sensors that are not visible to the user without disassembling.
What to do if water from the drain flows onto the floor?
Most likely, the drainage hole inside the chamber is clogged or the external drainage tray above the compressor is overfilled/displaced. Check the inner funnel on the back wall of the refrigerator compartment and clean it with a brush. Make sure that the refrigerator itself is level, without tilting forward.
