Modern models of household appliances are often equipped with No Frost systems, but the classic two-chamber units of the Belarusian brand Atlant are still very popular due to their reliability and affordability. Owners of such devices need to regularly carry out the defrosting procedure, since natural air circulation in them is not provided for by the design. Ignoring this process leads to the formation of a thick ice crust, which not only reduces the useful volume of the chambers, but also creates additional load on the compressor. Many users mistakenly believe that it is enough to simply turn off the device from the network and wait until the ice melts. However, for equipment compressor.
Many users mistakenly believe that it is enough to simply turn off the device from the network and wait for the ice to melt. However, for technology Atlant there are specific nuances, compliance with which will extend the service life evaporator and maintain the tightness of the seals. Incorrect actions, such as using sharp objects to chip ice or extreme temperature changes, can cause costly repairs. In this article we will analyze in detail the entire process of preparing, carrying out and completing defrosting.
It is important to understand that regular maintenance is not just a hygienic procedure, but a technical necessity. Ice thickness of more than 5 millimeters is already considered critical for effective work refrigeration unit. It acts as a heat insulator, interfering with the cooling of products, which is why the motor is forced to work almost non-stop. Let's look at an algorithm of actions that will protect your equipment and ensure ideal results.
Determining the type of defrosting system
Before taking active steps, you need to find out exactly what type of cooling system is installed in your model. The line Atlant includes both devices with manual defrosting and more modern options with partial automation. In two-chamber models, a combination is often found: in the freezer compartment, manual intervention is required, and in the refrigerator compartment there is a drip-type system If you have a model with a drip system in the main compartment, the water there flows down the back wall into a special chute and evaporates naturally when the compressor stops. In this case, complete defrosting of the entire device is required less often, but condition monitoring (Drop System).
If you have a model with a drip system in the main compartment, the water there flows down the back wall into a special chute and evaporates naturally when the compressor stops. In this case, complete defrosting of the entire device is required less often, but monitoring the condition freezers is still required. Make sure that the drainage hole is not clogged with crumbs or ice, otherwise moisture will begin to accumulate on the shelves.
⚠️ Attention: If a layer of snow or ice has formed on the back wall of the refrigerator compartment, this may indicate a malfunction thermostat or a loose fit doors, and not about the need for urgent defrosting.
To accurately determine the type of your model, refer to the technical documentation or find a nameplate with characteristics. It is usually located inside the camera or on the back wall of the case. Knowing the exact modification will help you avoid unnecessary manipulations with working components of the cooling system.
Preparation for the defrosting procedure
Proper preparation takes almost as much time as the defrosting process itself, and is the key to safety. The first step should always be to empty the interior space of food. Plan the procedure in advance in order to have time to use perishable supplies or transfer them to another cold place, for example, on a balcony (in winter) or in a thermal bag with refrigerants.
Next you need to completely turn off the power supply. Unplug the plug from the socket, but do not pull the wire to avoid damaging the contacts. If the outlet is in a hard to reach location, use an extension cord or contact the electrical panel if possible and safe to do so. After turning off, immediately remove all removable elements: shelves, drawers, egg trays and bottle holders.
It is best to wash removable parts with warm water and a mild detergent separately from the sink. This is the ideal time to check the integrity of plastic guides and sealers doors. While the parts are drying, you can prepare a place to collect melt water. Cover the floor around the equipment with rags or towels, since water can flow not only inside the pan, but also out if the drainage hole is clogged.
Ice thawing process
The safest and recommended by the manufacturer Atlant defrosting method - natural thawing with the doors open. This method takes from 4 to 10 hours depending on the thickness of the ice and the room temperature, but it guarantees safety aluminum evaporator. Never try to speed up the process by using a hairdryer, hot water or heaters directed into the chamber. A sharp temperature change can lead to deformation of the plastic and cracking of the tubes.
If there is a lot of ice, you can put a pan with warm (not boiling water!) water inside on a wooden board or towel so as not to damage the shelf. The steam will speed up the melting, but be careful not to splash the water. Periodically wipe off any draining water with a rag to prevent it from freezing again in the drainage channel. The main thing in this stage is patience.
Is it possible to use salt to speed things up?
The use of salt or chemical reagents to sprinkle ice is strictly prohibited. Salt causes corrosion of the metal parts of the evaporator, and chemicals can be absorbed into the plastic and subsequently get into the food, which is hazardous to health.
During defrosting, carefully inspect the inner surface of the chambers for mechanical damage. If you find blisters on the back wall or signs of rust, this may be a sign of more serious problems with refrigeration circuit. In this case, after defrosting, it is recommended to call a specialist for diagnostics.
Cleaning and disinfection of internal surfaces
While the ice is melting or after the chambers are completely free of ice, the deep cleaning stage begins. Even if the refrigerator appears clean visually, bacteria and mold may remain on the walls, which can cause an unpleasant odor. To wash, use a baking soda solution (2 tablespoons per liter of water) or a special cleaner for household appliances. Avoid aggressive chemicals with chlorine or abrasive particles.
Pay special attention to the corners of the chambers and the rubber seal door. It is in the folds of rubber that dirt most often accumulates and fungus develops. Wipe the seal carefully, without stretching it, moving from the top corner to the bottom. If black spots of mold appear on the rubber, they can be carefully removed with a cotton swab dipped in hydrogen peroxide or vinegar solution.
After washing with chemicals or folk remedies, be sure to wipe all surfaces with a clean damp cloth to remove any remaining detergent. Then dry the cameras with paper or cloth towels. After turning on the device, wet surfaces can quickly become covered with a new layer of frost, since excess moisture in the air instantly freezes on the cold walls.
Drainage system and care for it
A critical element that is often forgotten is the drainage hole. In models Atlant with a drip system, it is located in the lower part of the rear wall of the refrigerator compartment. Through it, the condensate flows into a tray above the compressor, where it evaporates. If this hole is clogged, water will remain inside, turning into a puddle or ice.
To clean, use a special soft brush-brush (often included) or a piece of soft wire/wadding twisted into a bundle. Carefully insert the tool into the hole and make several rotational movements. Do not push the debris deep, it is better to remove it out. After mechanical cleaning, pour 100-200 ml of warm water into the hole to ensure free flow.
| Element | What to clean | Frequency | Risk of ignoring |
|---|---|---|---|
| Drainage hole | Soft brush, warm water | Every defrost | Water in the chamber, ice |
| Rubber seal | Wet wipe, baking soda | Once a month | Loss of tightness |
| Rear grille (outside) | Vacuum cleaner, dry brush | Once every six months | Compressor overheating |
| Tray above the compressor | Wet rag | Once a year | Corrosion, odor |
If the water does not go away, repeat the procedure several times. In difficult cases, you can use an enema bulb to create pressure and break the plug, but proceed carefully so as not to damage the tubes inside the case.
Startup and first cycle of operation
After all surfaces have been washed and wiped dry, and the removable elements have been installed in their places, the refrigerator is ready to turn on. However, don't rush to load the products. Plug in the device and leave it idle for at least 2-3 hours. This is necessary in order to unit reach the desired temperature and trigger the circuit breaker.
In the first hours of operation, the engine may run longer than usual and make more noise - this is normal, active cooling of air volumes is taking place. Make sure the doors are tightly closed and have not been opened unnecessarily. Only after stable cold has established inside can you begin to gradually load food.
☑️ Ready for loading
Do not fill the chamber with warm foods immediately after defrosting, this will cause motor-compressor to work with overload. It is better to let him get into working mode in a calm state. If, after several hours of operation, uniform droplets of moisture appear on the back wall, it means that the system is working properly.
Typical errors during defrosting
There are a number of common misconceptions that can lead to equipment failure. One of the most common mistakes is using a knife or other sharp objects to chip ice. The evaporator housing in refrigerators Atlant is often made of thin aluminum. One awkward movement can break through the wall, which will lead to leakage freon and moisture entering the system. Repair in this case is not economically feasible.
Another mistake is ignoring the tilt of the housing when installing after defrosting. If the refrigerator is not level, the door may not fit tightly, or, conversely, water will pour out of the drain not into the tray, but onto the floor. Check the position of the legs and, if necessary, tighten them to ensure the correct slope back.
⚠️ Attention: Do not turn on the refrigerator immediately after defrosting if there is water left in the chamber. Liquid can get on electrical contacts or cause a short circuit when in contact with working elements.
Also, do not leave the refrigerator turned off for a long time (weeks or months) unattended. Internal components can dry out, and mold will quickly grow in a closed space without air circulation. If you plan to be away for a long time, leave the doors slightly open.
Frequency and maintenance schedule
How often should you defrost the refrigerator Atlant? The frequency depends on the model and operating conditions. For devices with manual defrosting in the freezer, the optimal interval is once every 3-4 months. If you notice that the ice layer has reached 5-7 mm earlier than this, the procedure should be carried out immediately. Frequent opening of doors, high humidity in the room or loading warm products accelerates the formation of ice.
The regularity of maintenance directly affects energy consumption. A 1 cm layer of ice increases energy consumption by about 15-20%, since the thermal conductivity of ice is worse than that of metal. In addition, the efficiency of freezing food decreases, which can shorten its shelf life.
Keep a simple maintenance schedule, for example, timing defrosting with changing seasons or holidays. This will help you develop a habit and prevent the chambers from becoming critically fouled with ice. Remember that prevention is always cheaper and easier than complex repairs of refrigeration equipment.
What to do if the refrigerator does not turn on after defrosting?
If, after being plugged in, the refrigerator is silent and does not make any sounds, check for electricity in the outlet (connect another device). If the network is working properly, the compressor thermal protection relay may have tripped due to overheating or a power surge. Wait 30-60 minutes and try to turn it on again. If there is no result, the problem may be in the thermostat or start relay, you need to call a technician.
Is it possible to defrost a refrigerator without unplugging it?
Absolutely not. Defrosting is only possible when the power supply is completely turned off. A running compressor will try to compensate for the heat from the melting ice, working for wear, which will lead to its rapid failure. In addition, getting water on operating electrical components is life-threatening.
Why did a strong smell appear after defrosting?
The smell may appear if you used aggressive chemicals and did not wash them off well, or if there was stagnant water in the drainage system in which bacteria multiplied. The smell can also come from rubber parts if they have been in contact with chemicals. Rinse the chambers again with a solution of soda and citric acid, ventilate well.
Do door hinges need to be lubricated after defrosting?
Special lubricant for hinges is usually not required each time defrosting. However, if you notice a squeaking or stiffness in the door, you can lubricate the hinges with silicone grease. Do not use edible oils (sunflower, olive), as they oxidize over time, thicken and begin to smell unpleasant, attracting dirt.
How to understand that defrosting was successful?
Successful defrosting is characterized by the complete disappearance of ice, dry internal surfaces, the absence of puddles under the refrigerator and a clean drainage hole. After turning on, the device should reach the temperature in a standard time (2-4 hours) and turn off on its own, which will confirm the serviceability of the thermostat.
