Defrosting an Atlant freezer with two compressors: complete instructions

Owners of Belarusian brand refrigerators are often faced with the need for scheduled maintenance, and the question of how to defrost a separate Atlant 2 compressor freezer is one of the most popular among users. The presence of two independent cooling circuits greatly simplifies life, allowing you to turn off only the freezer compartment while food continues to be stored in the refrigerator compartment. However, even in systems with fully automated ice formation processes, there is periodically a need for manual intervention to maintain efficient operation of the unit.

The process of removing ice crust requires compliance with a certain sequence of actions so as not to damage the delicate evaporator and not to break the tightness of the seals. Unlike old single-compressor models, here you are dealing with more complex electronics and separate thermostats, which dictates its own safety rules. Proper defrosting extends the life of the compressor and reduces the energy consumption of the device.

Many users mistakenly believe that the presence of a system No Frost completely eliminates the need for defrosting, but this is not entirely true. Even in modern models, over time a layer of frost can accumulate on the dampers or in hard-to-reach places in the air ducts, especially if the door is used frequently or has not been closed tightly. Let's look at the algorithm of actions for models with two motors in detail.

⚠️ Attention: Before starting any manipulations with the power supply, make sure that your hands are dry and the floor under the refrigerator is not slippery to avoid injuries when working with water and electricity.

The principle of operation of the Atlant two-compressor system

Refrigerators of the brand Atlant, equipped with two compressors, are actually two independent devices in one housing. One motor is responsible for cooling the refrigerator compartment, and the second is solely responsible for the freezer compartment. This architecture allows servicing of one compartment without affecting the temperature regime in another. This is a key advantage that must be used wisely.

When you initiate defrosting of the freezer, the refrigerator compartment continues to operate as normal, maintaining the set parameters. Thermoregulator or the electronic control module at this moment continues to cycle on and off the first compressor. It is important to understand that heat flows between the chambers still exist, so keeping the freezer door open for a long time can indirectly affect the temperature in the upper compartment.

The water drainage system in such models often has separate channels. In the freezer, the water from the melting ice has to go somewhere, and unless the design provides for automatic draining when the compressor is turned off (which often happens in older models with a “crying” evaporator in the freezer), you will have to collect the water manually. In new models with No Frost moisture evaporates through the heater, but during manual defrosting this mechanism does not work.

• 🧊 Independent temperature control in each compartment allows you to save energy.
• ❄️ Turning off the freezer does not affect the safety of food in the fridge compartment.
• ⚙️ Two compressors are quieter, since each of them is less loaded.
• 💧 The condensate removal system may require manual control when completely defrosting.

Understanding this mechanics is necessary in order not to panic if, after turning off the freezer, the refrigerator continues to buzz. This works as a second circuit, keeping your vegetables and drinks fresh. Insulation of chambers Atlant models are made with high quality, which minimizes heat exchange during the procedure.

⚠️ Attention: Do not try to speed up the defrosting process by opening the door of the refrigerator compartment to “release the cold” from freezers - this will disrupt the temperature regime for storing food from above.

Preparation for the defrosting procedure

Before taking active steps, it is necessary to properly prepare the workplace and the unit itself. Safety and the safety of food is priority number one. Start by reviewing the contents of the freezer: if there is a lot of frozen food, take care of where to put them during the procedure.

The ideal option would be to use thermal bags or ice packs if defrosting is planned quickly. However, if the ice layer is large, the process may take from 3 to 10 hours. During this time, food should not be at room temperature, otherwise it may begin to spoil. Prepare water containers and absorbent materials in advance.

You will need the following tools and accessories for effective work:

• 🧽 Deep baking trays or basins for collecting melting water.
• 🧻 Terry towels or rags for wiping shelves and walls.
• 🧤 Rubber gloves to protect hands from cold and household chemicals.
• 🧼 Mild detergent for final surface treatment.

Free up space in front of the refrigerator. You will need to be able to open the freezer door, bend over, and possibly rearrange shelves. Remove the mat if it is slippery to eliminate the risk of falling. Electrical cord Should be easily accessible for quick shutdown if necessary, although in dual-compressor models a complete shutdown is often not required.

Step-by-step instructions: how to turn off only the freezer

The most important step is to properly turn off the freezer. In two-compressor refrigerators Atlant this is usually the responsibility of a separate temperature regulator located inside the freezer or on the top panel of the case, depending on the model. Find the switch marked with a snowflake icon or the letter "M" (freezer).

Turn the control to the "0" or "Off" position. In some electronic models, you need to hold down a certain combination of buttons or select the “Vacation” mode (if it turns off only the freezer, read the instructions for the specific model), but most often it is enough to simply set the minimum temperature or shutdown mode. After this, the freezer compressor should go silent after a few minutes.

If your model allows physical shutdown (for example, through a separate plug, which is rare, but happens in some older versions or when installing additional equipment), use this method. However, the standard procedure for most users is to change the thermostat. Make sure that the freezer compressor operation indicator has gone out.

After shutting down, let the system “rest” for a couple minutes before opening the door to remove food. This will allow the pressures in the system to stabilize. Now you can start removing boxes and trays.

The process of defrosting and removing ice

When the freezer is turned off and empty of food, the main stage begins. Natural defrosting is the safest method for plastic parts. Just leave the door open. The ice will begin to melt on its own under the influence of room temperature. evaporator and plastic parts. Just leave the door open. The ice will begin to melt on its own when exposed to room temperature.

Place flat containers on the bottom of the chamber (or on the bottom shelf if the bottom is occupied by a grate) to collect water. Place thick towels under and in front of the refrigerator, as water may overflow or drip from the seal. Periodically, every 30-40 minutes, check the fullness of the containers and change wet rags.

It is strictly forbidden to use sharp objects (knives, screwdrivers, scrapers) to chip ice. The inner walls of the Atlant freezer contain tubes with refrigerant, which are located very close to the surface. Mechanical damage will lead to an instant release of freon and expensive repairs, which are often not economically feasible.

⚠️ Attention: Using hair dryers, heating pads or boiling water to speed up the melting of ice is not recommended by manufacturers. A sharp temperature change can cause deformation of the plastic and cracks in the evaporator housing.

If there is a lot of ice and there is no time to wait, you can use the “warm air cushion” method. Place a bowl of hot (not boiling!) water in the chamber and close the door for 10-15 minutes. Steam will speed up the melting. Repeat the procedure several times. This is a more gentle method than direct heating with a hairdryer.

After the main body of ice has melted, thoroughly wipe all surfaces. Pay special attention to corners and rubber seals where water may have accumulated. A clean chamber is the key to the absence of unpleasant odors in the future.

What to do if the ice does not melt?

If the ice crust does not melt within 5-6 hours, the defrost sensor or heating element (in No Frost models) may be faulty. Check whether the freezer compressor has actually turned off by placing your hand on the grille at the back - it should be warm or room temperature, not hot.

Care for the No Frost system in the freezer

Many Atlant models with two compressors are equipped with a system No Frost in the freezer compartment. In such units, ice should not freeze on food and walls. However, this does not mean that they never need defrosting. Once every year and a half, it is recommended to carry out preventive defrosting to clean the drainage channels and check the operation of the drain.

In the No Frost system, moisture is removed through a special drainage hole. Over time, dust, crumbs, or mold can accumulate there, causing a clog. As a result, water begins to accumulate at the bottom of the chamber or under the drawers. When defrosting, be sure to check this hole.

To clean the drainage:

• 🔍 Remove the bottom panel in the freezer (if the design allows).
• 💧 Gently rinse the hole with warm water from a syringe.
• 🧹 Use a soft brush or cotton swab to remove dirt.

Also check the condition of the defrost heating element (heating element), if visual inspection is possible. It should not have any signs of burnout or mechanical damage. A working defrosting system is a guarantee that the refrigerator will operate silently and efficiently.

After cleaning the drainage and removing any remaining ice, leave the chamber open for another hour to dry completely. A humid environment is an ideal place for bacteria to grow. Make sure that all parts are completely dry before assembly.

Completing the procedure and starting the refrigerator

The final stage is preparing to turn it on. Wipe all interior surfaces thoroughly with a dry, clean cloth. There should not be a drop of water left, especially in the corners and around the seal. Assemble the drawers and shelves, install them in their places.

Now you can turn on the freezer. Move the temperature regulator to the operating position. It usually takes 2 to 6 hours for the initial temperature to set. At this time, do not load food into the freezer, let it return to normal. The refrigerator compartment, which has been working all this time, most likely will not even notice the break, but check the temperature there too.

It is better to load food in small portions so as not to create a sudden thermal load on the newly started compressor. Stable temperature it will be established after about a day of active operation. Listen to the operation of the unit: there should be no extraneous knocking or excessive noise.

Typical errors and measures precautions

Despite its apparent simplicity, users often make mistakes that can shorten the life of the refrigerator. One of the most common is trying to break the ice with a knife. Damage to the cooling circuit is the reason for 90% of cases when a refrigerator ends up as scrap. Be sensible and patient.

Another mistake is not cleaning the rear condenser grille. While the freezer is defrosting, wipe the dust off the black grille at the back of the refrigerator (only with a dry cloth!). A condenser clogged with dust causes the compressor to work with overload, which leads to increased electricity consumption and wear.

Also, you should not turn on the refrigerator immediately if you accidentally broke the seal or carried out some manipulations with the tubes (although this is excluded during simple defrosting). But if you touched the cooling system, let the oil drain into the compressor (about 2-4 hours in a vertical position).

Is it possible to defrost the Atlant freezer with a hairdryer?

Using a hairdryer is not recommended by the instructions. Hot air can melt the plastic housing of the evaporator or deform the seals. In addition, there is a risk of moisture getting inside the electrical components of the hair dryer or the refrigerator itself, which will lead to a short circuit. Better be patient.

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

The time depends on the thickness of the ice and the temperature in the room. Typically the process takes from 3 to 8 hours. If the ice layer is more than 1 cm, the process may take longer. Do not use aggressive acceleration methods.

Do you need to unplug the refrigerator when defrosting the freezer?

In two-compressor models, it is enough to turn the freezer control to the “0” or “Off” position. Complete unplugging is required only if you plan to wash the entire refrigerator or are leaving for a long time. However, if you doubt the serviceability of the thermostat, it is better to turn off the power to the device completely.

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

Let it work for 4-6 hours without loading food. If the temperature does not drop, check to see if the door is tightly closed, if the hose is kinked, and listen to whether the compressor is working. If the compressor is humming, but there is no cold, or is silent, you need to call a technician.
