How to defrost the freezer in a two-compressor Atlant refrigerator

Owners of Belarusian-made equipment often wonder about proper maintenance, especially when a snow coat begins to grow on the walls of the freezer compartment. The two-compressor system, which many models are equipped with Atlanthas its own technical features that distinguish it from single-circuit analogues. Understanding the operation of two independent refrigeration circuits is critical to performing safe and efficient defrosting without the risk of damaging compressors or compromising system seals.

Unlike older models, modern units can be equipped with a system No Frostthat theoretically does not require manual intervention, but even in this case, preventative cleaning is necessary. If you are the owner of a model with a drip system or combined defrosting, then regular removal of ice becomes a mandatory procedure to maintain energy efficiency. Ignoring the growth of ice more than 5 millimeters thick leads to increased load on the motor and increased energy consumption.

The defrosting process in dual-circuit devices is faster, since the compressors operate independently of each other, but requires careful attention to the temperature conditions of each compartment. You don't have to worry about the food in the refrigerator compartment going bad while you're working in the freezer if you follow the correct sequence of steps. Next, we will analyze in detail each stage of preparation and procedure so that your Atlant refrigerator serves for many years.

The principle of operation of a two-compressor system and the need for defrosting

The main feature of the equipment Atlant with two compressors is the complete autonomy of the refrigeration and freezer chambers. Each compartment has its own evaporator, fan (if a moisture removal system is provided) and a compressor unit. This means that if there is a need to defrost the freezer, you can turn off only it, leaving the refrigeration compartment to operate as normal to preserve food freshness.

The need for manual defrosting arises in models where the technology of complete No Frost is not implemented in the freezer compartment. In such devices, moisture from the products settles on the cold walls of the evaporator, gradually turning into an ice crust. Over time, this layer becomes a heat insulator, forcing the compressor to work longer and harder to maintain the set temperature inside the chamber.

⚠️ Attention: In models with a full No Frost system, manual defrosting is required only in the event of a breakdown of the moisture remover or a clogged drainage hole, which is indicated by the appearance of ice on the back wall.

Frequency The procedure depends on the intensity of use of the equipment and the humidity of the products you store. Typically, manufacturers recommend carrying out complete defrosting at least once a year, however, with active use or high humidity in the room, this may be required more often. Regular maintenance allows you to avoid situations when the door stops closing tightly due to ice, which leads to loss of cold.

Preparatory stage before starting the procedure

Before starting the active defrosting phase, it is necessary to perform a number of preparatory actions that will protect the equipment and simplify cleaning. First of all, you should empty the freezer of food. If it is winter outside, you can take them out to the balcony, otherwise use thermal bags or transfer the supplies to another working freezer.

Next you need to turn off the power to the specific compressor responsible for the freezer. On some models Atlant with electronic control, this can be done through the settings panel, turning the freezer into off mode while the refrigerator compartment continues to operate. If you have a mechanical control, you will have to disconnect the entire device from the power supply, but a two-compressor system allows you to do this faster, since the second circuit will quickly restore the temperature after switching on.

• 🧊 Prepare in advance a container for collecting melt water and several dry rags or sponges.
• 🔌 Check access to the outlet or the possibility of turning off a specific circuit through the electronic menu.
• 🧹 Remove all removable shelves and drawers from the freezer to facilitate access to the walls.
• 🌡️ Make sure that the room temperature is not lower than +5°C for the process to be effective.

It is also important to prepare the area around the refrigerator. Cover the floor in front of the doors with an absorbent cloth or towels, as if a large amount of ice melts, water may leak out of the tray. If your model has a special gutter for draining moisture, make sure that it is not clogged with food debris or crumbs.

Step-by-step instructions for defrosting the freezer

After all the preparatory work is completed, you can proceed to the direct defrosting process. Open the freezer door and leave it open. The natural process of melting ice is the safest for plastic elements and the evaporator, although it takes longer than using a hairdryer or hot water.

If you decide to speed up the process, you can use a hairdryer, but keep it at least 30-40 centimeters away from plastic surfaces and in no case direct a stream of hot air directly at the rubber door seal. High temperatures can deform the seal or melt the plastic, which will lead to seal failure in the future. It is also permissible to spray warm water from a spray bottle onto the ice crust.

During the melting process, regularly remove loose pieces of ice and scoop out water so that it does not get on the electrical contacts or inside the compressor housing. You should be especially careful with the drainage hole if it is located at the bottom of the chamber - clean it with a special brush or a cotton swab if you notice a blockage.

What to do if the ice does not come off?

If the ice crust is very thick and does not come off even after prolonged exposure, do not try to pick it out with a knife or sharp objects. This is guaranteed to damage the evaporator and leak freon. It is better to repeat the procedure of spraying with warm water or use a hairdryer at minimum power, constantly changing the heating zone.

Care for the No Frost system and drip defrosting

Owners of refrigerators Atlant with the system No Frost should understand that "defrosting" for This means, first of all, hygienic cleaning and maintenance of ventilation ducts. In such units, ice freezes on a hidden evaporator and is automatically removed during defrost cycles, but dust and food particles can clog the air ducts.

To service the system, it is necessary to remove the back panel inside the freezer (if the design allows the user to do this according to the instructions) and carefully vacuum the area around the fan and defrost heater. It is also important to check the condition of the drain tube, which drains condensate into the evaporation tank on the compressor. A blockage in this tube is a common cause of ice appearing on the bottom of the chamber or on the door.

⚠️ Attention: Removing the back panel on No Frost models may void the warranty. Check the official user manual or contact a service center if you are not confident in your abilities.

The drip system in the refrigerator compartment of two-compressor models usually does not require intervention other than periodic washing. However, if you notice that water does not drain into the drainage hole on the back wall of the refrigerator, clean it with a soft wire or a special brush. This will prevent the formation of puddles on the shelves and the appearance of an unpleasant odor.

Cleaning and washing the internal surfaces

After complete removal of ice and After snow comes the stage of thorough cleaning of internal surfaces. Even if the chamber visually seems clean, during operation bacteria could settle there or food odors could be absorbed. Use a soft sponge and warm soapy water to clean the walls, shelves and drawers.

To remove stubborn dirt or yellow discoloration on plastic, you can use a baking soda solution. It is strictly forbidden to use abrasive powders, metal brushes or aggressive chemical solvents, which can scratch the surface or damage the plastic evaporator. Scratches on plastic will eventually become a place for dirt and bacteria to accumulate, which will be difficult to get rid of.

• 🧼 Thoroughly rinse all removable drawers and grates under running water.
• 🌿 Wipe the inner walls with a soda solution (1 tablespoon per liter of water) to eliminate odors.
• 🚿 Be sure to rinse all surfaces with clean water to remove any remaining detergent.
• 🧻 Wipe the camera dry with a dry soft cloth before turning it on.

Pay special attention to the rubber seal on the door. Dirt and mold often accumulate in its folds. Wipe the seal with a cotton pad soaked in a weak vinegar solution or a special rubber care product to maintain its elasticity and tightness.

Completing the process and the first start

The final stage of defrosting is drying and the correct first start. Make sure the inside of the chamber is completely dry, especially in the recesses and around the seals. When you first turn on the residual moisture, it will instantly turn into an ice crust, nullifying all your efforts. Leave the doors open for 15-20 minutes for the final evaporation of moisture.

Place all shelves and drawers in their places. Now you can plug in the refrigerator. Since you have a two-compressor model, you can first start only the freezer compartment, if the design allows for separate control, or turn on the entire appliance. Let the equipment run idle for 1-2 hours so that it reaches operating temperature conditions.

Only after the refrigerator reaches the required temperature (usually the indicator goes out or a signal sounds), you can load food. A sudden load of warm food will cause the compressor to work with overload, which is undesirable immediately after defrosting. Distribute food evenly without blocking the ventilation holes.

Common mistakes and ways to prevent them

Many users make common mistakes when trying to speed up process or neglecting safety rules. The most common one is using a knife or screwdriver to chip the ice. Mechanical damage to the evaporator tubes leads to an immediate release of freon and requires expensive professional repairs with sealing and refilling.

Another mistake is turning on hot water directly into the chamber in large volumes. Sudden temperature changes can lead to cracks in the plastic housing or deformation of internal bulkheads. In addition, a large amount of water can flow into the technical holes, causing a short circuit or corrosion of the contacts.

⚠️ Attention: Do not turn on the refrigerator until you are sure that it is completely dry and warmed up to room temperature, especially if you used a hair dryer or hot water.

Also, do not ignore the appearance of extraneous noise or buzzing after defrosting. If you notice that the refrigerator is louder than usual or does not turn off for a long time, the fan may have been damaged during cleaning or the temperature sensor may have been dislodged. In such cases, it is better to contact a specialist.

Is it possible to defrost in the cold?

It is absolutely forbidden to take the refrigerator out into the cold to speed up defrosting. Extreme cold can damage compressor oil and plastic components. Defrosting should take place at room temperature.

Table of recommended service intervals

For the convenience of users, we have compiled a summary table that will help determine the optimal defrosting frequency depending on the operating conditions of your Atlanta.

Following these recommendations will extend the life of your refrigerator and keep food fresh. Remember that regular maintenance takes less time and money than subsequent repairs.

Is it necessary to completely defrost an Atlant refrigerator with No Frost?

Full defrosting with unplugging for models with Full No Frost is rarely required, usually once a year for hygienic cleaning. The system itself removes condensation, but dust and odors require manual removal.

How long does it take to defrost a two-compressor refrigerator?

With natural defrosting, the process takes from 6 to 12 hours, depending on the thickness of the ice and the room temperature. Using a hairdryer can reduce this time to 1 hour, but requires caution.

Is it possible to turn on the second compressor while the first one is defrosting?

Yes, in two-compressor models this is possible. You can turn off only the freezer compartment, leaving the refrigerator compartment to work, which is especially convenient in the summer.

What to do if the refrigerator does not freeze after defrosting?

Let the appliances stand turned off for another 30-60 minutes. If the problem is not resolved, check that the door is closed tightly and that the temperature settings are not off. If the problem persists, contact the service.

How to remove odor after defrosting?

Use activated carbon, lemon or special odor absorbers. Thoroughly rinse the chamber with a solution of soda or vinegar, paying attention to the drainage hole.
