Two-compressor models of refrigerators Atlant are deservedly considered one of the most reliable units in the post-Soviet space. Their key feature is the complete autonomy of the refrigerator and freezer compartments, which allows servicing one area without the need to turn off the entire device. However, even the most reliable equipment requires regular maintenance, and ignoring the formation of ice crust can lead to serious problems with thermoregulation and increased energy consumption.
Many owners mistakenly believe that the presence of a No Frost system or partial automatic defrosting completely eliminates the need for manual intervention. In reality, especially in conditions of high humidity or when doors are opened frequently, a layer of frost gradually grows on the evaporator of the freezer, which over time turns into a dense coat of ice. Defrosting freezers is a mandatory procedure that technical regulations require to be carried out at least once a year to maintain optimal compressor performance.
In this article we will analyze in detail the algorithm of actions for safely removing ice in two-compressor models, where the design allows you to turn off only the freezer compartment. You will learn how to speed up the process without harming the plastic elements and why you should not use sharp objects to chip off ice. The right approach will extend the life of your Atlant refrigerator and preserve the freshness of products.
Design features of two-compressor models
The main technical advantage of refrigerators Atlant with two compressors is independence cooling circuits. While one compressor works to maintain low temperatures in the freezer, the second provides coldness in the refrigerator compartment. This engineering feature radically changes the approach to defrosting: you do not need to unload all the products from the main chamber and wait for the stocks there to spoil.
When you initiate the defrosting process, you turn off only one of the compressors - the one responsible for the freezer. The second unit continues to operate as normal, maintaining the temperature in the upper compartment at +2...+5 degrees Celsius. This allows you to store perishable products, such as milk, meat or ready-made meals, directly during preventive maintenance.
It is important to understand that despite the autonomy, heat exchange between the chambers still occurs through a common partition. If the freezer is left open for too long, the temperature in the refrigerator compartment may begin to rise due to the insulation being compromised. Therefore defrosting time should be monitored, trying to stay within the 10-12 hours recommended by the manufacturer, although the actual melting of the ice takes much less time.
⚠️ Attention: Never try to turn off the freezer compressor by pulling out individual wires from the terminal box. This may result in a short circuit or failure of the control board. Use only standard controls on the case or in the electronic module.
The evaporator design in such models is usually hidden behind the rear plastic panel or located in the form of an open coil, depending on the series. Atlant. In models with an open evaporator, ice freezes directly on shelves and products, while in systems with a closed circuit (partial No Frost), ice accumulates mainly on the bottom and walls, not directly affecting the contents, but blocking the ventilation ducts.
Preparation for the defrosting procedure
Before When starting active operations, it is necessary to properly prepare the workplace and the unit itself. The first step is to estimate the amount of food in your freezer. If the chamber is completely full, take care in advance about where to put the supplies. Thermal bags, ice packs or, in winter, a balcony (provided the outside temperature is below freezing) are suitable for this.
Next, you should free up the space in front of the refrigerator. You will need access not only to the front panel, but also to the back of the device to clean up possible water. Prepare several terry towels, flat containers to collect melt water and, if necessary, a rubber mat to prevent water from getting onto the flooring of your neighbors below in case of leakage through the cracks.
☑️ Preparation checklist
A critically important step is to properly turn off the unit. Dual-compressor models Atlant often use a single power button or two independent switches. You need to find a temperature controller specifically for the freezer. On mechanical models, this is a rotary knob that must be set to the “0” or “Off” position. In electronic models, you should hold down the corresponding button or use the key combination described in the instructions.
After setting the regulator to the zero position, wait 1-2 minutes. During this time, the refrigerant in the system will have time to stabilize, and the compressor will be guaranteed to stop. Only after this can you safely open the freezer door and begin removing drawers and shelves. Plastic becomes fragile in the cold, so remove the elements carefully, without sudden jerks.
Step-by-step instructions for defrosting
The process of natural melting of ice is the safest for your refrigerator Atlant. Once you have removed all the food, removed the shelves and drawers, and turned off the power to the freezer, leave the door open. Place towels folded in several layers under the bottom edge of the freezer or install a shallow tray, as the initial flow of water can be intense.
The time for complete defrosting depends on the thickness of the ice crust and the room temperature. On average, it takes 3 to 5 hours for the ice to completely disappear. Do not try to speed up the process by using a hairdryer or hot water if the ice layer does not exceed 5–7 mm. A sudden temperature change can cause deformation of the plastic case or damage the evaporator tubes, which will lead to freon leakage.
If the ice coat is thick, you can carefully help the process by using special soft plastic scrapers, which often come with the refrigerator. Movements should be directed from top to bottom, without strong pressure. It is strictly forbidden to use knives, screwdrivers or other metal objects - one careless puncture of the evaporator tube will make repairs expensive and difficult.
Check towels and empty water containers regularly during the melting process. Stagnant water may begin to flow into technical openings or under the door seal, which will lead to the appearance of an unpleasant odor or mold. After all the ice has melted, wipe the inside of the chamber dry with a clean rag.
Methods to speed up the process (Safe)
Sometimes the situation requires reducing the downtime of the freezer. There are safe ways to speed up the melting of ice in the refrigerator Atlantwithout resorting to aggressive mechanical action. One of the most effective methods is to use the heat of the surrounding air. If the room is heated, you can direct a flow of warm air from a fan (not a hair dryer!) towards the open freezer from a distance of at least 1 meter.
Another gentle method is to use containers with hot water. Pour boiling water into bowls or pans, place them on a wooden board or thick towel inside the chamber and close the door. The steam will settle on the ice walls, accelerating their melting. You need to repeat the procedure every 15–20 minutes as the water cools. This method is especially effective for removing ice from hard-to-reach corners.
Below is a table comparing different defrosting methods in terms of effectiveness and risks:
| Method | Exposure time | Risk of damage | Recommendation |
|---|---|---|---|
| Natural melting | 3–5 hours | Absent | Recommended by the manufacturer |
| Hot water in bowls | 1–2 hours | Minimum | Acceptable with a thick layer of ice |
| Fan (warm air) | 1.5–2.5 hours | Low | Safe if not brought close |
| Hair dryer (hot air) | 30–40 minutes | High | Not recommended (risk of plastic) |
⚠️ Attention: The use of a hair dryer or open fire (candles, burners) is strictly prohibited. Local overheating can melt the rubber seals or deform the internal plastic, which then cannot be restored.
Remember that even when using accelerating methods, it is important to control the temperature of the exhaust air. It should not be extremely high. Safe defrosting speed is a priority. If you are in a hurry, it is better to temporarily transfer the food to another place and carry out high-quality defrosting than to risk the integrity of the cooling system.
Caring for the chamber after defrosting
After the ice has completely disappeared and the surfaces have been wiped dry, do not rush to immediately turn on the refrigerator. Allow the camera to “air out” for 15–20 minutes so that the musty smell, if any, disappears. This will also allow the temperature of the internal walls to become equal to room temperature, which will reduce the load on the compressor when first starting.
Wash the internal surfaces thoroughly with a weak soda solution or a special refrigerator cleaner. Avoid using harsh chemicals, abrasive powders or chlorine-containing products, which can damage the finish or leave a lingering odor that lingers in the food. Pay special attention to the recesses and grooves for water drainage - dirt often accumulates there.
How to wash the refrigerator?
A baking soda solution is ideal for washing (1 tablespoon per 1 liter of warm water). It perfectly degreases and deodorizes. You can also use a weak solution of vinegar or citric acid to remove limescale. After washing, be sure to wipe all surfaces with a clean damp cloth and then dry.
Check the condition of the rubber seals on the door. During use, a coating may have formed on them, which prevents a tight fit. Wipe them with a soft sponge soaked in soapy water. If you find cracks or creases through which the cold escapes, consider replacing the seal, as this directly affects the frequency of ice formation in the future.
Before loading products, make sure that all removable elements (drawers, shelves, trays) are completely dry. Moisture on the plastic can quickly turn into a crust of ice during the first freeze cycle. Place the drawers in place, close the door and only then turn on the power to the freezer.
Starting and setting the temperature mode
Turning on the two-compressor Atlanta after defrosting requires following a certain sequence. First, make sure the power cord is securely plugged in. Then turn the freezer temperature regulator from position “0” to operating mode. For most models, the optimal temperature is -18°C.
In mechanical models, the knob must be turned to the mark corresponding to the required temperature. In electronic models with a display, press the power button and wait until the current temperature is displayed. Please note that immediately after switching on, the compressor may work with increased load in order to reach the set temperature - this is a normal operating situation.
It is recommended not to load food into the chamber immediately, but after 1.5–2 hours of operation, when the temperature inside has stabilized. If you put warm or room temperature food into a freshly started chamber, the compressor will run continuously trying to cool the large volume, which can cause it to overheat. Cool the empty compartment first, then gradually add supplies.
⚠️ Attention: In the first hours after turning on, the refrigerator may be louder than usual. Don't be alarmed by this: the system takes time to reach nominal mode. If the noise does not subside after a day or is accompanied by vibration of the case, contact the service.
Frequent errors when defrosting
Despite the apparent simplicity of the procedure, many users make mistakes that shorten the service life of the equipment. The most common of them is the use of sharp objects to chip ice. Even a light blow with a knife on the evaporator tube leads to the instant release of freon and the entry of air into the system. Repair in this case requires replacing the compressor and re-welding the tubes, which is often not economically feasible.
Another mistake is turning on the refrigerator immediately after the last stream of water has drained, without drying it out. Residual moisture at the bottom of the chamber or in the drainage holes will turn into an ice plug during sudden cooling. This can disrupt air circulation or damage temperature sensors if they are located at the bottom of the chamber.
Also, owners often forget to check the installation level of the refrigerator. If Atlant stands on a slope, water during defrosting may not enter the evaporator (in models with a drip system) or flow out, but accumulate in one corner, creating the illusion of a leak. Use a building level to check the horizontal position and adjust the legs of the refrigerator.
Preventing the formation of ice crust
To reduce the need for defrosting, you should follow simple operating rules. First of all, make sure that the door seals tightly. Check the seal regularly for dirt and damage. If the door does not close tightly, moist air constantly enters the chamber, which instantly condenses and freezes.
Do not place warm foods in the chamber. The evaporation of moisture from hot soup or freshly cooked meat creates a huge amount of steam, which settles on the walls and turns into a thick layer of frost. Allow food to cool to room temperature before freezing.
Regularly check the operation of the water drainage system (if provided by the design). The condensate drain hole must not be clogged with crumbs or ice. It can be carefully cleaned with a special stick or a cotton swab dipped in warm water. Cleanliness inside the chamber is the key to long and trouble-free operation of your Atlant refrigerator refrigerator Atlant.
Is it possible to defrost a refrigerator without unplugging it?
In two-compressor models Atlant this is possible if you turn the regulator freezer temperature to the “0” or “Off” position, while the second compressor continues to operate. However, for complete safety and to eliminate the risk of a short circuit when water gets on the contacts, experts still recommend completely de-energizing the unit before starting water procedures.
How long should the refrigerator rest before turning it on again?
After defrosting and washing the chamber, you do not need to wait long. 15–20 minutes is enough to ventilate and equalize the temperature of the walls. The main thing is to make sure that all surfaces are dry. Long downtime (days or weeks) unnecessarily is not necessary and is even harmful for compressor lubrication.
What to do if the refrigerator does not freeze after defrosting?
If more than 2-3 hours have passed after turning it on and the temperature does not drop, check whether the door is tightly closed and whether the regulator is installed correctly. If the compressor works, but there is no cold, the cooling circuit may have been damaged due to careless defrosting (freon leakage). In this case, you need to call a specialist.
Does the seal need to be lubricated after defrosting?
Yes, this is a useful procedure. Wiping the rubber seal with silicone grease or glycerin (you can use a special wipe for caring for rubber) preserves its elasticity, prevents drying out and cracking, ensuring a tight fit of the door.
