Modern Atlant refrigerators are famous for their reliability and durability, but even the most advanced equipment requires periodic maintenance. One of the mandatory maintenance stages is complete defrosting, which allows you to remove the ice crust, clean the internal surfaces and extend the life of the compressor. Owners often wonder how to correctly perform this procedure without damaging complex electronics or the cooling system.
The process of preparing for defrosting depends on the specific model of your device and the type of control system. If you have two-compressor a unit, you can defrost the chambers separately without fear for the safety of the food in the second compartment. In the case of single-compressor a system with a No Frost system or drip defrosting, the approach will be different, requiring a complete power outage or switching to a special service mode.
Below we will analyze in detail the algorithms of action for various series of equipment, we will consider nuances of working with electronic controls and answer frequently asked questions about safety. Compliance with the technology will avoid breakdowns and ensure efficient operation of the equipment after switching on.
Determining the type of cooling system and model
Before you begin any manipulations with the power supply or settings, you need to clearly understand what kind of device you are dealing with. The line Atlant refrigerators includes hundreds of modifications, and the algorithm of actions for a model of the 1990s will be radically different from actions with a modern smart unit. An error in identification can lead to damage to products or even failure of the control board.
First of all, pay attention to the number of compressors. If you see two motors at the back of the device, then you are the happy owner of a system with an independent cooling circuit. This allows turn off the freezer separate from the refrigerator compartment, which greatly simplifies the defrosting procedure. In such models, it is often enough to simply turn off the corresponding switch or set the temperature to zero.
If there is only one compressor, and there is no ice inside the freezer thanks to the system No Frost or Frost Free, then the concept of “defrosting” is more likely to be used for you hygienic character. In such cases, a complete shutdown is rarely required, usually only for general cleaning or during long periods of absence. Mechanical models with manual control require a complete shutdown and waiting for the natural melting of the ice.
⚠️ Attention: Do not try to determine the type of system only by the appearance of the control panel. Some models with electronics may have one compressor, but complex logic for the operation of the dampers. Always check the technical data sheet or sticker on the inner wall of the camera.
It is also important to consider the age of the equipment. In older models Atlant with mechanical thermostats, the lack of automatic defrosting requires strict control over the ice melting process. New models with a digital display may have built-in timers that remind you of the need for maintenance.
Preparation for the defrosting procedure
Quality preparation is 80% of the success of the entire operation. Incorrect actions at this stage can lead to food damage or an emergency in the kitchen. Before you begin defrosting the refrigerator, you need to empty the cameras of their contents. Products that you plan to save should be transferred to another refrigerator, taken out to the balcony (in winter) or tightly wrapped in blankets with refrigerant.
Pay special attention to the safety of electrical appliances. Water from melting ice can leak out of the tray and onto electrical parts or simply onto the floor, creating a slip hazard. Prepare in advance several large rags, sponges and containers to collect water. If the kitchen floor is sensitive to moisture, cover the area around the device with old towels or waterproof film.
☑️ Preparing for defrosting
Do not forget to disconnect the device itself from the network. To do this, you need to remove the plug from the socket. Never pull on the wire, as this may damage the insulation or contacts. If access to the outlet is difficult, use an extension cord or temporarily turn off the circuit breaker in the panel, but only if you are confident in your actions. After turning off, allow the equipment to “rest” for a couple of minutes before starting active operations.
Remove all removable elements: shelves, drawers, egg trays and ice trays. It is better to wash them separately in warm water and a mild detergent. Plastic parts that have been exposed to frost become fragile, so wash them with warm, but not hot water to avoid deformation.
Shutdown algorithm for different Atlant models
The shutdown procedure directly depends on the design features of your model. Owners two-compressor refrigerators are the luckiest: they do not need to sacrifice products from the main chamber. There are usually two temperature controls located on the control panel or inside the refrigerator compartment. To defrost the freezer, just move its regulator to the “0” or “Off” position, leaving the main circuit operating in normal mode.
For models with electronic control (series with a display on the door), the process may look like activating a special mode. It is often necessary to press and hold a certain combination of buttons, such as the defrost or mode switch button, for 3-5 seconds. The corresponding indicator should light up on the display, indicating that the freezer compressor has entered service mode or turned off.
| Model type | Action | Waiting time | Risk for food in cold storage |
|---|---|---|---|
| Two-compressor | Turn off the freezer regulator | Until the ice disappears | None |
| Single-compressor (Mechanics) | Complete disconnection from the network | 10-24 hours | High (you need to remove everything) |
| With No Frost system | Shutdown for washing (optional) | 2-4 hours | Medium (short-term) |
If you have a classic single-compressor refrigerator with a drip system, then turning off just the freezer will not work. The compressor pumps freon through both circuits simultaneously. In this case, the only correct solution is to completely de-energize the device. You must be prepared for the fact that the refrigerator compartment will also defrost, so all the products will have to be removed.
What to do if the regulator is jammed?
If the handle of the mechanical thermostat does not turn, do not use excessive force - you can break the rod. Try rocking it slightly from side to side. If this does not help, it is better to defrost by completely disconnecting from the outlet than to risk the integrity of the unit.
Natural defrosting process
After you have made all the necessary switches or disconnected the device from the network, the longest stage begins - waiting. Natural defrosting is the only safe way to remove the ice crust. Ice should melt on its own when exposed to room temperature. This process can take from 4 to 24 hours depending on the thickness of the ice and the temperature in the room.
It is strictly forbidden to use hair dryers, fan heaters or heaters to speed up the process. Sudden temperature changes can cause deformation of plastic panels, cracks in the evaporator, or damage to seals. Also, do not try to break off the ice with a knife, screwdriver or other sharp objects. One awkward move and you will break through the channel through which it circulates refrigerant. Repair in this case will not be economically feasible.
To speed up the process, you can place containers with hot water inside the chambers. Steam will settle on the walls and speed up the melting, but do this carefully, placing planks or thick towels under the pans so as not to damage the plastic bottom. The chamber doors should be kept open to ensure air circulation.
During the melting process, make sure that the water does not overflow over the edge of the pan. Periodically scoop out the liquid or blot it with rags. If water begins to flow under the unit, immediately tilt the refrigerator (being careful) or add additional absorbent materials.
⚠️ Warning: Never turn on the refrigerator until the inside is completely dry. Residual moisture may get on the electrical contacts or cause a short circuit when the compressor starts. Allow the device to stand open for another 30-60 minutes after the last ice has disappeared.
Care of seals and internal surfaces
While the chambers are free of food and ice, this is the ideal time for general cleaning. During operation, bacteria, mold, or unpleasant odors may have settled on the walls. Use a soft sponge and a solution of baking soda or a special refrigerator cleaner. Avoid aggressive chemicals, abrasive powders and chlorine-containing substances that can damage the coating.
Special attention is required rubber seals on the doors. It is in their folds that dirt most often accumulates and fungus develops. Carefully wipe the seal around the entire perimeter, bending it (without fanaticism) to clean the inside. After washing, lubricate the rubber with a special silicone grease or glycerin - this will restore its elasticity and extend its service life, ensuring a tight fit of the door.
Don't forget to wash and dry all removed shelves and drawers. Plastic and glass must be completely dry before reinstalling. Wet shelves can freeze to the walls or become a source of excess moisture after switching on.
Starting the refrigerator after defrosting
When you are sure that the inside is dry and clean, you can begin assembling and starting it up. Replace all shelves, drawers and trays. Make sure they are secured correctly and are not loose. Close the doors and only then turn on the device. If your model has a separate power button, press it.
After turning on, the compressor will start working. In the first minutes this is normal - the equipment reaches operating mode. Take your time loading products. Let the refrigerator run idle for at least 1-2 hours (for No Frost models) or up to 4-6 hours (for models with a drip system) so that a stable temperature is established inside.
Monitor the operation of the device during the first day. Pay attention to the following signs:
- 🧊 Uniform cooling in all chambers.
- 🔇 No extraneous knocks, rumbles or whistles.
- 💧 No puddles under the device (condensation is acceptable, but not flow water).
- ❄️ Correct switching on and off of the compressor according to the cycle.
If you notice that the refrigerator runs continuously without turning off, or does not get cold inside, check the thermostat settings. The settings may have gone wrong or the door may not fit tightly. If problems persist, contact the service center.
Typical errors and precautions
Many users, trying to save time, make mistakes that can cost them expensive repairs. The most common mistake is mechanical chipping of ice. As already mentioned, this is a direct path to a freon leak. Even if it seems to you that the layer of ice is thin and comes off easily, the risk of damaging the evaporator is too great.
Another common mistake is ignoring the tilt when transporting or moving. If you move the refrigerator to clean behind it, let it stand upright for at least 2-4 hours before turning it on. The oil from the compressor must drain into the crankcase, otherwise water hammer may occur.
Also, do not turn on the device immediately after washing if you have used a lot of water. Make sure that moisture does not get into the ventilation holes or onto the rear grille where the electrical components are located.
Is it possible to defrost the Atlant refrigerator with a hairdryer?
The use of a hairdryer is highly not recommended by manufacturers. Hot air can heat the plastic unevenly, causing it to deform or cause microcracks. In addition, there is a risk of moisture from the air or condensation getting into electrical parts. It is better to spend more time on natural defrosting than to risk the integrity of the case.
How long should the refrigerator dry after defrosting?
The minimum drying time is 30-60 minutes after the ice has completely melted. However, if you carried out wet cleaning with a lot of water, it is better to increase this period to 2 hours. Make sure that there are no drops left in the recesses and joints of the panels.
Why does the refrigerator not turn off for a long time after defrosting?
This is normal. After defrosting, it is warm inside, and the unit takes time to cool the volume of the chambers to the set temperatures. The compressor will work in enhanced mode until the target values are reached. If it does not turn off for more than 24 hours, this is a cause for concern.
Is it necessary to defrost a No Frost refrigerator?
The No Frost system involves automatic removal of moisture, so the formation of ice in it is minimal. However, once a year (or as it becomes dirty), it is still recommended to completely turn off such equipment, wash and dry it to maintain hygiene and check the operation of the fans.
