Modern two-compressor models of the Belarusian brand Atlant are deservedly popular due to their reliability and the possibility of independent operation of cooling circuits. However, even the most advanced equipment requires regular maintenance to maintain factory performance and energy efficiency. Many owners are wondering whether it is necessary to turn off the unit altogether if a layer of ice has formed on the walls of the chamber.
Unlike old single-compressor models, here the defrosting process has its own nuances associated with the design of the evaporator and the control system. Incorrect actions can lead to failure of the sensors or failure of the seals. Full defrosting is necessary not only for removing the ice crust, but also for hygienic treatment of internal surfaces.
In this material we will analyze in detail the algorithm of actions that will allow you to carry out the procedure safely and not damage the complex electronics of your device. You will learn how to speed up the process of natural ice melting without using aggressive methods and why a two-compressor scheme requires a special approach to timing.
Design features of two-compressor Atlant models
The main difference between such refrigerators is the presence of two independent refrigerant circuits and two separate motor-compressors. One compressor is responsible for the operation of the refrigerator compartment, and the second is solely responsible for the freezer compartment. This allows maintenance freezer without the need to defrost the upper compartment, which greatly simplifies food storage.
The control system in such models, be it mechanical thermostats or an electronic unit Control, responds to the temperature in each chamber separately. When one of the compressors is turned off, the second one can continue to operate normally, maintaining the set parameters. It is this autonomy that dictates the specific procedure for preparing for washing.
⚠️ Attention: Despite the independence of the circuits, prolonged opening of the freezer doors can lead to an increase in the temperature in the refrigerator compartment due to disruption of heat exchange, so control the process.
It is important to understand that the evaporator in the freezer can be hidden behind a plastic panel (in models with a system No Frost or Frost Free) or be open (in models with manual defrosting). The frequency of procedures and methods for removing ice plugs depend on the type of system.
When forced defrosting is necessary
The manufacturer recommends complete cleaning of ice and dirt at least once a year. However, there are situations when forced defrosting is required immediately, regardless of the schedule. Ignoring these signs leads to overload of the compressor and increased energy consumption.
If you notice that the door no longer closes tightly due to ice on the seal, or the layer of frost on the walls exceeds 5-7 millimeters, the procedure cannot be postponed. In manually controlled models, freezing occurs faster, and control of ice thickness falls on the user's shoulders.
- 🧊 The thickness of the ice crust on the walls or door exceeds the permissible standards specified in the passport.
- 🚪 The sealing rubber is deformed by ice and does not provide tightness.
- 🌡️ The temperature in the chamber no longer corresponds to the set values, despite the operation of the compressor.
- 👃 An unpleasant odor has appeared that cannot be eliminated by normal ventilation.
In some cases, ice can block the ventilation holes, which interferes with air circulation. This is especially critical for systems with forced circulation, where icing of the air exhaust channel can lead to fan failure.
Preparatory stage before shutdown
Before starting active actions, it is necessary to properly prepare the unit. This will ensure the safety and security of the products inside. The first step is always to empty the chambers of the contents.
Remove all food and place it in a cool place or wrap it in thick cloth and blankets to slow defrosting. In two-compressor models, the refrigerator compartment can be left on if the design allows blocking the access of warm air from the open freezer, but it is better to play it safe and turn off both circuits.
☑️ Preparing for defrosting
Be sure to remove all removable elements: shelves, trays, baskets and containers. They should be washed separately in warm water using a mild detergent. Plastic becomes brittle at low temperatures, so avoid sudden temperature changes when washing.
Prepare a place to collect melt water. Cover the floor around the refrigerator with absorbent cloth or place flat trays. Water can leak not only from the drainage hole, but also through leaks in the seal if the tilt of the housing is broken.
Step-by-step instructions for defrosting
The safest method recommended by the manufacturer is natural defrosting. It takes longer, but ensures that there are no thermal shocks to the evaporator materials and plastic parts. The process takes from 10 to 24 hours depending on the amount of ice.
After unplugging the appliance, leave the freezer doors open. To speed up the process, you can place a container of hot water inside, but not boiling water. The water temperature should not exceed 60 degrees Celsius so as not to damage the plastic.
| Stage | Action | Execution time |
|---|---|---|
| 1 | Disconnecting from the network and removing products | 10-15 minutes |
| 2 | Natural melting of ice (main stage) | 12-24 hours |
| 3 | Removing residual water and wiping | 20-30 minutes |
| 4 | Drying and turning on work | 2-4 hours |
If the ice does not come off on its own, you can carefully use the plastic scraper included in the kit or a wooden spatula. Metal tools are strictly prohibited, as they can damage thin tubes evaporatorwhich will lead to freon leakage and costly repairs.
What to do if the ice does not melt?
If the natural melting process is too slow, You can direct a stream of warm (not hot!) air from a hairdryer onto the ice crust, holding it at a distance of at least 30-40 cm. Move the hairdryer constantly, without stopping at one point, so as not to melt the plastic.
Cleaning and disinfection of internal surfaces
After all the ice has melted and the water has been removed, you must thoroughly wash the inner chamber. Even if there is no visible dirt, bacteria or mold could remain on the walls, causing an unpleasant odor. Use a weak solution of baking soda or a special refrigerator cleaner.
Wipe all surfaces with a soft sponge, paying special attention to corners, panel joints and where the evaporator tubes exit. Do not use abrasive powders, hard brushes or aggressive chemicals containing chlorine or acids.
⚠️ Attention: Avoid getting large amounts of water on the back wall of the chamber where the controls and temperature sensors are located. Moisture in electrical contacts can cause a short circuit.
After wet cleaning, be sure to wipe all surfaces dry with a clean cotton cloth. Remaining moisture can quickly turn into a new layer of ice when turned on, especially in the contact area with cold walls. Allow the camera to dry completely and ventilate for 15-20 minutes.
Completing the process and first launch
When the chamber is completely dry, reinstall all removed shelves, drawers and containers. Make sure they fit correctly and do not interfere with the free movement of the door. Now you can connect the refrigerator to the electrical network.
In two-compressor models Atlant the start occurs independently for each circuit. After turning on, allow the freezer to run empty for 2-3 hours. This is necessary for the system to reach operating temperature conditions before loading products.
Check the operation of the indicators (if any) and listen to the sounds of the compressor. There should be no extraneous knocking, hissing or vibrations. After a few hours, you can add food, but do not immediately overload the chamber with a large volume of warm food.
- ✅ Set the temperature regulator to the middle position.
- ✅ Check the tightness of the door after the seal has cooled.
- ✅ Make sure that the drainage hole is free and the water is leaving.
Frequently asked questions (FAQ)
Is it possible to defrost the freezer with a hairdryer to speed up the process?
Using a hairdryer is permissible only in extreme cases and with great caution. The air flow should be warm, not hot, and the distance to the ice should be at least 30 cm. Prolonged exposure to hot air can deform plastic parts and damage the seal.
Is it necessary to defrost the No Frost system?
The No Frost system (or Low Frost) involves automatic removal of moisture, therefore, the formation of an ice coat is not provided for in it. However, once every year or two it is recommended to carry out preventive defrosting for washing and disinfection, since dust and bacteria still accumulate.
What to do if after defrosting the refrigerator does not freeze?
Perhaps the compressor has not yet reached the operating mode or the protection has tripped. Wait 4-6 hours. If the problem persists, check that the door is closed tightly and that the thermostat is set correctly. In two-compressor models, one of the starting relays could fail.
How often does Atlant with two compressors need to be defrosted?
For models with manual defrosting - as an ice crust more than 5 mm thick forms, but at least once a year. For systems with partial No Frost one preventative cleaning every 12-18 months is sufficient.
