Modern two-chamber units of the brand Atlanteven equipped with the system No Frost, periodically require complete disconnection from the power supply to carry out maintenance work. Despite manufacturers' assurances that frost does not form, moisture can accumulate in the hidden channels of the evaporator over time, which turns into an ice crust and disrupts air circulation. Regular defrosting of the Atlant refrigerator allows you to extend the life of the compressor and avoid the appearance of foreign odors inside the chambers.
Many owners mistakenly believe that if there is no visible snow deposits in the freezer compartment, then the device does not need to be defrosted at all. However, the technical regulations for the operation of household appliances provide for scheduled maintenance at least once a year. This is necessary not only to remove microscopic ice, but also for disinfection internal surfaces, cleaning drainage holes and checking the tightness of sealing rubber bands.
The process of preparing for service begins long before you unplug the cord from the outlet. It is necessary to plan in advance a time when access to the power grid will be free and food will not spoil. In this article, we will analyze in detail the algorithm of actions for models with a drip system and system No Frostso that you can safely carry out the procedure and avoid damage to plastic or electronics.
Preparing for the defrosting procedure and releasing the chambers
The first and most important step is to completely disconnect the unit from the power supply. It is not enough to simply turn off the button on the case, if there is one; you must physically remove the cord plug from the outlet. This ensures that compressor t will not start up accidentally while you are handling water or sharp objects for cleaning. After turning off, leave the doors open for 10–15 minutes so that the internal pressure equalizes and the initial melting process occurs naturally.
Next, you should completely empty the refrigerator and freezer compartments of food. It is better to transfer all perishable items (perishable foods) to bowls with ice or to another cold place if you do not plan to consume them immediately. Shelves, vegetable drawers, egg trays and door containers must be removed. Plastic elements become brittle at low temperatures, so remove them carefullywithout sharp jerks so as not to break the guides.
To collect melt water, prepare several large towels, rags or special absorbent wipes. If the kitchen floor is sensitive to moisture (for example, laminate or wood), it is recommended to cover the area in front of the refrigerator with thick film or place a flat tray. Water flowing from the drainage channel may be dirty and contain bacteria, so its contact with a clean floor is undesirable.
☑️ Preparing for defrosting
While the chambers are empty, wipe the rubber contour of the door with a weak solution of vinegar or a special rubber care product. This will ensure a tight fit of the door after switching on, which is critical for energy efficiency Atlant refrigerator.
Natural defrosting: a safe method for any model
The most gentle way to remove ice is to wait. After turning off the appliance and removing food, simply leave the doors open. Depending on the room temperature and the thickness of the ice crust, this process can take from 4 to 24 hours. For two-chamber models Atlant with a large freezer, the average time is about 10-12 hours.
During this period, it is not recommended to use a hair dryer or other heating devices, since a sharp temperature change can lead to deformation the plastic case or damage to the evaporator tubes sealed in the walls of the chamber. Natural melting ensures that all materials in the unit are subject to minimal stress. You can speed up the process by placing bowls of hot water inside the chambers, but not boiling water.
Periodically, about once an hour, you need to go to the unit and change wet towels, wiping off the flowing water. If water is coming out of the drain hole, make sure it is not clogged with food debris or mold. For cleaning, you can use a soft syringe or a special brush, which often comes with instructions.
While the melting process is underway, it’s time to start washing the removed shelves and drawers. They can be washed with warm water and a mild detergent. Do not use abrasive powders or hard sponges, which may scratch the clear plastic. After washing, rinse the parts thoroughly and let them dry so that condensation does not form on them during assembly.
Accelerated defrosting: risks and control methods
Sometimes situations arise when it is not possible to wait a day, and you need to speed up the process. In such cases, the use of additional heat sources is allowed, but with extreme caution. It is strictly forbidden to pick the ice with a knife, screwdriver or other sharp objects. One awkward movement can break through a thin wall evaporatorwhich will lead to a refrigerant leak and costly repairs, which are often not economically feasible.
The safest method of speeding up is to use bowls of hot water. Pour water into pots or deep bowls and place them on wooden planks or folded towels on shelves inside the chamber. Close the door for 15–20 minutes. The steam will warm the ice, speeding up its melting. Repeat the procedure as the water cools. This method is especially effective for models Atlant with a drip system.
⚠️ Attention: The use of hair dryers, heaters or heat guns for defrosting is not recommended by manufacturers. A directed jet of hot air can melt plastic interior parts, damage wiring, or cause cracks in metal due to local overheating.
If you decide to use a hairdryer, keep it at least 30–40 cm from the surface of the ice and constantly move it without stopping in one place. Make sure that hot air does not reach the rubber seals and electronic control units, which are often located in the upper part of the refrigerator compartment. It is best to use the warm rather than hot air mode.
What to do if the ice does not melt?
If the ice crust is very thick and does not melt even with hot water, the defrost sensor or heating element (in No Frost models) may be faulty. In this case, mechanical chipping is prohibited. Leave the refrigerator turned off for a longer period or call a technician for diagnostics.
Features of defrosting the No Frost system in Atlanta
Owners of two-chamber refrigerators Atlant with the system No Frost often wonder: do they need to be defrosted? The answer is clear: yes, it is necessary. Although the open shelves of the freezer remain dry, the hidden evaporator located behind the rear plastic panel also develops frost. In normal mode, this frost is removed by automatic defrosting, but over time, an ice plug or mud mass may form in the drainage tube.
When the drainage is clogged, the condensate does not go into the tray, but accumulates at the bottom of the freezer, forming a puddle that freezes. In some models, water may even leak outside, under the refrigerator. Complete defrosting within 24 hours allows the ice in the hidden channels to melt and come out, naturally cleaning the system. For models with No Frost this is the only opportunity to clean hidden air ducts without disassembling the case.
| System type | Defrost frequency | Average time | Key feature |
|---|---|---|---|
| Drip (crying) | 1–2 times a year | 8–12 hours | Ice visible on the walls |
| No Frost (full) | 1 time per year | 12–24 hours | Ice hidden behind the panel |
| Combined | once a year | 10–15 hours | Different modes in cameras |
| Low Frost | once a year | 6–10 hours | Minimum plaque |
When defrosting the system No Frost pay special attention to the fan. After removing the back panel (if you have repair skills) or simply through the grille holes, you can check whether anything is preventing the rotation of the blades. However, for normal preventive defrosting, the user simply needs to withstand the shutdown time so that all internal moisture evaporates or glass.
Caring for the drainage system and removing odors
One of the main reasons for the appearance of an unpleasant odor in the refrigerator Atlant is contamination of the drainage hole. During the defrosting process, when water actively drains, the channel is naturally flushed. However, if the odor persists, further cleaning may be necessary. Use a soft brush or twisted cotton wool on a wire, soaked in a disinfectant solution.
To eliminate persistent odors after washing the cameras, it is recommended to wipe the internal surfaces with a solution of baking soda (1 tablespoon per liter of water) or a weak solution of vinegar. These products perfectly neutralize bacteria and do not leave toxic traces. Do not use chlorine-containing products, as their vapors can be absorbed into the plastic and subsequently transferred to the products.
After treating with chemicals or folk remedies, be sure to let the chambers completely dry and ventilate. It is best to collect moisture with paper towels, as they absorb well and do not leave lint. Make sure that there is no water left in the recesses and joints of the plastic, which will turn into ice when turned on.
⚠️ Attention: If the smell does not disappear after defrosting and cleaning, the problem may not be dirt, but a malfunction. Check the expiration date of the products, the condition of the seal or the operation of the ventilation system. In rare cases, a smell may indicate burnt wiring insulation.
Starting the refrigerator after defrosting
When the chambers are completely dry and clean, you can begin assembly. Replace all shelves, drawers and containers. Make sure they are in place and secure. Now you can turn on the refrigerator. However, don't rush to load the products. Let the unit run idle for at least 2-4 hours so that it reaches the required temperature and (the compressor) reaches operating mode.
Indicators on the front panel refrigerator Atlant will help control the process. When the alarm indicator goes off or the sufficient cooling indicator lights up, you can gradually load food. You should not fill the chambers completely at once - this will create an excessive load on the Atlant refrigerator compressor. It is better to do this in stages over several hours.
During the first hours of operation, listen to the sounds of the unit. A quiet hum and occasional gurgling of the refrigerant is considered normal. If you hear loud knocking, grinding or whistling noises, immediately turn off the device and contact a service center. Perhaps an error was made during the defrosting or assembly process, or a hidden malfunction appeared.
Frequent errors when servicing Atlant refrigerators
Many users make typical mistakes that negate the benefits of defrosting. One of the most common is turning on a wet refrigerator. Residual moisture on the walls and shelves instantly turns into an ice crust, and the cycle has to be repeated again. Always wipe all surfaces dry before turning on.
Another mistake is the use of aggressive chemicals. Acetone, gasoline, and strong solvents can damage the plastic of the inner case, making it cloudy or sticky. For plastic Atlant only mild detergents are suitable. Also, do not use metal brushes to clean the condenser at the back of the refrigerator - this can damage the thin radiator tubes.
Do not ignore the regularity of procedures. Even if it seems to you that the refrigerator is working normally, annual defrosting is required. It prevents the formation of “age-old” ice build-ups, which over time can block the operation of dampers or fans, which will lead to breakdown of expensive system components. No Frost.
Is it possible to defrost a refrigerator on the balcony?
No, it is not. The refrigerator should defrost at room temperature. In cold weather, the oil in the compressor will thicken, and the plastic will become brittle, which will lead to breakage the next time it is turned on.
How long should you keep the refrigerator turned off?
The optimal time for completely defrosting an Atlant two-chamber refrigerator is from 12 to 24 hours. This time is enough for all the ice to melt, including hard-to-reach places in the No Frost system, and the inner surface to dry. The minimum time is 4–6 hours, but it is only suitable for models with a thin layer of ice.
What to do if after defrosting the refrigerator does not freeze?
If after turning on the unit hums, but does not cool, the system may have been damaged due to careless defrosting (for example, hit with a knife) or an electronics failure. Let it sit off for another 1-2 hours and try turning it on again. If there is no result, call a technician, there is likely a freon leak.
Do you need to wash the condenser at the back of the refrigerator?
Yes, cleaning the black lattice radiator (condenser) at the back or bottom of the refrigerator from dust and animal hair significantly improves heat transfer. This reduces the load on the compressor and energy consumption. This can be done with a vacuum cleaner or a soft brush during defrosting.
Can a steamer be used for defrosting?
The use of steam generators or steamers is highly not recommended. The steam has high temperature and pressure, which can lead to deformation of plastic elements, peeling of decorative panels and damage to electrical contacts inside the case.
Why did a whistle appear after defrosting?
A whistling sound may indicate that water has entered the heating elements (if they were open) or friction in the fan motor due to residual ice. If the whistling does not stop after a day of operation, you need to check the condition of the blower fan.
