Two-compressor models Atlant are deservedly popular due to their reliability and the ability to independently adjust temperatures in the chambers. However, even the most advanced equipment requires periodic maintenance, and defrosting is the key step here. Many owners mistakenly believe that the presence of a system No Frost completely eliminates the need for manual intervention, but this is not entirely true.
In the freezer compartment of such units, ice can still accumulate, especially if the door is often opened or products with a high moisture content are placed in the chamber. Ignoring this process leads to an increase in energy consumption and a decrease in cooling efficiency. Full cyclic defrosting is required at least once a year, even if visually the ice crust seems thin.
The process of preparing for cleaning a two-compressor system has its own nuances that distinguish it from servicing single-compressor analogues. You will be working with two independent refrigerant circuits, which requires careful attention to the sequence of actions. Correct implementation of all stages guarantees a long service life compressors and the preservation of an optimal microclimate inside the chambers.
Preparation of equipment and premises for the procedure
Before starting any work, it is necessary to ensure safe conditions for the procedure. A two-compressor system Atlant uses more electricity, and proper shutdown is critical to protecting the electrical network and the unit itself. First, clear the space around the refrigerator to provide free access to the back wall and ventilation grilles.
Prepare a container for collecting melt water and absorbent materials in advance. In two-chamber models, the volume of water can be significant, especially if ice has accumulated over several months. Do not rely solely on the factory tray; it may not be enough during intense melting.
⚠️ Attention: Make sure that the floor in the work area is level and stable. Shifting a heavy unit on a wet, slippery floor may result in injury or damage to the frame.
You will need the following supplies for effective operation:
- 🧽 Sponges and soft microfiber cloths to remove moisture
- 🪣 A wide basin or several containers for water
- 🧴 Detergent for household appliances without abrasives
- 🔌 Dry towel for wiping electrical contacts
Pay special attention to ventilation. If the refrigerator is built into a niche or stands close to the wall, move it at least 50-70 cm. This will ensure air circulation and speed up the process of evaporation of moisture from the rear panels.
Correct shutdown of a two-compressor system
The most important step is the correct shutdown of power. Unlike simple models, it is important to understand that you have two independent motors. Before unplugging the cord from the socket, it is recommended to set the temperature controls in both compartments to the “0” or “Off” position.
This action is not strictly necessary from a technical point of view for modern electronic systems, but helps to avoid voltage surges at the moment of a circuit break if the plug has play. After moving the regulators to the neutral position, you can remove the plug from the network.
☑️ Checklist before disconnecting
Do not try to disconnect the refrigerator by pulling the wire. Grab only the fork body. If the socket is located in a hard-to-reach place behind the unit, it is better to temporarily move the equipment to gain direct access to the power source.
After turning off, do not rush to immediately open the doors wide if the chambers are very cold. Sudden temperature changes and the influx of warm, humid air can cause condensation on internal elements, which then freezes in hard-to-reach places. Let the unit stand closed for 10-15 minutes.
Releasing the chambers and removing elements
When the equipment is turned off, it is necessary to completely empty the internal volume. All products should be transferred to another cold place or used insulated containers. Even leaving food at room temperature for a short time can affect its safety.
Remove all removable elements: shelves, drawers, egg trays and bottle holders. In two-compressor models Atlant the design of the shelves may differ in the upper and lower compartments. It is better to take plastic parts to the bathroom for washing, where they are easier to clean from dirt and odors.
Glass shelves should not be washed with hot water immediately after removal from the freezer. Sudden heating can lead to microcracks or complete destruction of tempered glass. Let them warm up to room temperature for 20-30 minutes.
Inspect the rubber seals on the doors. While the drawers and shelves are removed, you have ideal access to check the condition seal. It is the loose fit of the door that most often causes the rapid growth of ice in systems that supposedly do not require defrosting.
The process of natural defrosting and acceleration of melting
Now comes the longest stage - the melting of the ice. Dual-compressor models are characterized by the presence of an evaporator in the freezer, hidden behind a plastic panel, and an open evaporator in the refrigerator compartment (if it is not completely No Frost). Ice must melt naturally.
It is strictly forbidden to use sharp objects (knives, screwdrivers) to chip ice. Damage to the evaporator tubes will lead to leakage refrigerant and expensive repairs, which are often not economically feasible. It is also not recommended to use a hairdryer to speed up the process, since a directed flow of hot air can deform plastic parts and damage wiring.
Why can’t you heat with a hairdryer?
Using a hairdryer creates uneven heating. The plastic contracts and expands at different rates, which leads to cracks. In addition, hot air can melt the insulation of the wires located next to the evaporator, which will create a risk of a short circuit the next time you turn it on.
To speed up the process without harm to the equipment, you can place containers with warm (not hot!) water inside the chambers. Change the water as it cools. This will create a mild thermal effect that is safe for all materials.
Regularly wipe off any draining water to prevent it from getting on the floor or inside technical openings. In dual-compressor models, drainage holes can be located in both compartments. Make sure they are not clogged with crumbs or dirt.
Cleaning the drainage system and internal surfaces
After the ice has completely melted, thoroughly rinse the internal surfaces. Use a weak solution of baking soda or a special refrigerator cleaner. Avoid using strong acids or alkalis, as they can damage the protective coating.
Pay special attention to the drainage hole in the refrigerator compartment. It often gets clogged, which leads to puddles under the vegetable drawers. You can clean it using a special flexible brush or a cotton swab.
| Cleaning area | Recommended product | Frequency of treatment |
|---|---|---|
| Internal walls | Soda solution (1 tbsp per 1 liter of water) | At each defrost |
| Door seals | Warm water with mild soap | Once every 3 months |
| Drainage hole | Warm water, brush | At each defrost |
| Outer body | Glass cleaner or polish | As it gets dirty |
Remember to wash and dry all removed shelves and drawers before reinstalling them. Wet elements can immediately freeze to the walls or become a source of excess moisture.
Completion of work and first start-up
The final stage is assembly and switching on. Make sure all surfaces are completely dry. Residual moisture at the first start will instantly turn into an ice crust, nullifying all your efforts.
Put the shelves and drawers in their places. Check that nothing prevents the doors from closing freely. Now you can turn on the refrigerator. Two-compressor models Atlant are characterized by sequential starting of engines with a slight delay, which is the norm.
Do not load products immediately. Let the equipment run idle for 1.5–2 hours so that it reaches operating mode and stabilizes the temperature in both circuits. Only after this can you return the products.
⚠️ Attention: If after turning on you hear a loud knocking, humming or the refrigerator does not cool after 3-4 hours, immediately turn it off and contact the service center. This may indicate a malfunction that occurred during operation.
Typical mistakes and answers to questions
Users often make mistakes that shorten the life of the equipment. For example, trying to quickly defrost a refrigerator by placing a pan of boiling water inside can lead to cracks in the plastic. It is also dangerous to leave the refrigerator turned off for a long time without drying - mold may appear.
Another common mistake is ignoring the slope of the floor. If the refrigerator is not level, the door may not close completely on its own, which will lead to permanent freezing. Adjust the legs so that the door opens smoothly and closes itself at an opening angle of about 30-45 degrees.
Below are answers to frequently asked questions that will help you avoid common ones problems.
Is it possible to defrost only the freezer compartment, leaving the refrigeration compartment running?
In two-compressor models, it is theoretically possible to turn off one compressor, leaving the second one to work. However, in practice this is difficult to implement, since the regulators are often located in one place, and the physical separation of the circuits within the housing does not allow them to be completely isolated for defrosting. It’s easier and safer to turn off the entire unit.
What to do if there is a plastic smell after defrosting?
A slight odor may be associated with the heating of the elements during the first start-up or detergent residue. Ventilate the cells. If the smell is pungent and does not go away after a day, the wiring or insulation may have overheated - in this case, diagnostics by a specialist is required.
How often should the drainage hole be washed?
You should check its condition every time it is completely defrosted, that is, once a year. However, if you notice water under the crisper drawers early, cleaning should be done immediately, regardless of the schedule.
Can a steam cleaner be used for defrosting?
Using a steam cleaner is not recommended. High steam temperatures and pressure can damage plastic parts, seals and electronic components, as well as drive moisture deep into the insulation, causing corrosion and mold.
