Modern models of the Belarusian brand, equipped with two compressors, are often perceived by owners as fully automated devices that do not require human intervention in the defrosting process. Indeed, the presence of a system in the refrigeration chamber greatly simplifies life, eliminating the need to deal with ice every week. However, even in such advanced units as manual defrosting is required. This is due to the characteristics of operation, the condition of the seals or the specific operating conditions of the evaporator in the freezer compartment, where ice can still accumulate. No Frost or Frost Free in the refrigerator compartment greatly simplifies life, eliminating the need to deal with ice every week.
However, even in such advanced units as Atlant XM 6021 or XM 6221, manual defrosting may be required over time. This is due to operating conditions, the condition of the seals, or the specific operating conditions of the evaporator in the freezer compartment, where ice can still accumulate.
Understanding how to correctly carry out this procedure for your specific model will help avoid breakdowns and will extend the service life of equipment. Unlike old single-compressor systems, there are some nuances associated with the independent operation of the circuits and control electronics.
Features of a two-compressor cooling system
The main difference between such refrigerators is the presence of two separate refrigerant circuits and two compressor motors. This means that the refrigerator and freezer compartments operate independently of each other, which allows defrost one compartment while the other continues to operate normally.
This design provides more precise temperature control and energy savings, since the compressors are turned on only when it is really necessary to maintain the set parameters. In models with the system Full No Frost ice does not form at all due to the constant circulation of dry air.
Nevertheless, in the freezer compartment of some modifications there may be partial automatic defrosting, but you should not completely rely on it for years. Periodic maintenance is necessary to remove dust from the heat exchanger and check the condition of the drainage channels.
Ignoring simple maintenance rules can lead to the defrosting system failing ahead of time.
⚠️ Attention: If your refrigerator makes unusual sounds during the defrost cycle (clicking, humming), this may indicate a malfunction of the timer or heating element. Do not ignore such symptoms.
The electronic control board in such units strictly controls the operating and resting time of the motors. With frequent power outages or power surges in the network, failures in the algorithms may occur defrostingwhich will require manual intervention.
When manual defrosting is necessary
Many users mistakenly believe that the inscription No Frost on the body guarantees complete absence of ice forever. In practice, the thickness of frost on the evaporator may increase due to a loosely closed door or placement of hot products.
If you notice that the freezer has become less freezing and a noticeable layer of snow has appeared on the walls, it means that the automatic defrosting system is not coping or the drainage is clogged. In this case, manual defrosting is the only effective solution.
Also, the procedure must be carried out before a long departure or general cleaning of the kitchen. Leaving the refrigerator turned on unattended for several days is risky, especially if there is a possibility of power surges.
There are a number of signs indicating the need for urgent intervention:
- ❄️ The layer of frost or ice on the internal walls exceeds 5-7 millimeters.
- 💧 The appearance of puddles of water on the floor under the refrigerator due to the drain pan being overfilled.
- 🚪 The door stopped closing tightly due to ice frozen on the seal.
- 📉 The food in the freezer began to thaw, although the thermostat was set to maximum.
Ignoring these symptoms leads to increased load on the compressor, which is forced to work almost non-stop. This is a direct path to overheating and expensive repairs of the refrigeration unit Atlant.
Preparing for the defrosting procedure
Before starting any manipulations, it is necessary to empty the chambers of food. Take care in advance about where to put frozen meat or vegetables, since in a two-compressor model you can turn off the chambers individually.
If you are defrosting only the freezer, you do not need to transfer food from the refrigerator compartment anywhere. However, it is better to put the contents of the freezer in basins, wrap them in blankets or transfer them to a working neighboring unit.
Prepare a container for collecting water and rags. Although refrigerators Atlant have melt water drainage systems, if there is severe icing, it may not have time to go into the drainage hole.
☑️ Preparation checklist
In advance, find a soft plastic scraper or spatula that came with the kit. If it is lost, you can use a wooden spoon, but under no circumstances a knife or other sharp objects.
| Preparation stage | Necessary actions | Importance |
|---|---|---|
| Release | Remove all products and shelves | High |
| Floor protection | Lay with absorbent rags | Medium |
| Tools | Prepare a soft scraper | Critical |
| Safety | Check the integrity of the cord | High |
Make sure the floor around the refrigerator is dry and covered with rags. Melt water may contain particles of dirt and bacteria, so it is better to avoid contact with the floor covering.
Step-by-step instructions: how to defrost correctly
The process of defrosting a two-compressor refrigerator Atlant is technically simple, but requires a strict sequence of actions. First, you must completely turn off the power to the device from the outlet or set the temperature controls to the “0” / “Off” position.
After disconnecting, leave the chamber doors open. The natural process of ice melting will take from 2 to 4 hours, depending on the thickness of the ice and the temperature in the room. It is strictly prohibited to speed up the process with a hair dryer or hot water. strictly prohibited.
If there is a lot of ice, you can carefully use a plastic scraper. Using light movements, pry up large pieces, but try not to put pressure on the back wall where the evaporator is located.
Sequence of actions:1. Remove food.
2. Disconnect from the network (or set to 0).
3. Open the doors.
4. Collect melting water.
5. Wipe dry.
6. Turn on after 30-60 minutes.
Water will flow into a special groove at the bottom of the chamber and go through the drainage channel into a container above the compressor. If the channel is clogged, carefully clean it with a soft wire or brush.
⚠️ Attention: Never use sharp metal objects to chip ice. One awkward movement can puncture the thin evaporator tube, and the refrigerator will have to be thrown away or expensively repaired.
After all the ice has melted, thoroughly wipe the internal surfaces with a dry soft cloth. Do not leave moisture in the corners and on the seals to prevent the rapid formation of ice again.
Why can’t you pour boiling water?
Pouring hot water onto the plastic body and shelves of the refrigerator is dangerous. A sharp temperature change can cause deformation of the plastic, cracks on the shelves and damage to the door seals.
Automatic defrosting systems in Atlant
Most modern two-compressor models are equipped with a system No Frost in the freezer compartment and a drip system (crying evaporator) in the refrigerator compartment. This combination is called Frost Free.
In No Frost mode, the fan drives air through the evaporator hidden behind the rear panel. The heating element is periodically turned on, which melts the yin on the evaporator, and the water goes into the drainage. The user does not notice this process.
In a refrigeration chamber with a drip system, moisture condenses on the back wall, freezes, and when the compressor stops, flows down the groove. If you see a “crying” surface on the back wall, this is a normal operating situation.
- 🔄 Cyclicity: Defrosting occurs automatically every 8-16 hours of compressor operation.
- 🌡️ Control: Sensors ensure that the temperature does not rise above what is safe for products.
- 💧 Drainage: All water evaporates from the hot surface of the compressor or goes into a special container.
However, if the system fails, ice can build up inside the housing, reducing the useful volume and worsening heat transfer. In such cases, even a “smart” refrigerator Atlant requires manual defrosting for a day for complete restoration.
Electronic control allows you to set different temperature conditions, but the basic defrosting algorithm is built into the factory settings and does not require user adjustment.
What you absolutely cannot do
There are a number of common mistakes that owners make when they want to speed up the process. These actions can lead to fatal damage to expensive equipment.
The most important rule: do not pick at the ice with a knife. Evaporator tubes in refrigerators Atlant are made of thin aluminum or copper. A breakdown of the tube leads to freon leakage and moisture entering the system, which requires complex evacuation and refilling.
It is also prohibited to use hair dryers, fan heaters, or pour boiling water directly onto an ice block. Sudden heating causes deformation of the plastic case, which then cannot be restored.
⚠️ Attention: Do not turn on the refrigerator immediately after the last piece of ice has melted. Allow the compressor and oils to stand for at least 30-60 minutes with it turned off.
Do not wash the internal shelves and drawers with hot water immediately after removing them from the freezer. Glass and plastic can burst from thermal shock. Let the parts warm up to room temperature.
Ignoring the instructions and trying to save time on defrosting often results in calling a technician and buying new components. Careful attitude is the key to long service.
Care after defrosting and frequently asked questions
After completing the procedure and drying the chambers, wipe the internal surfaces with a weak soda solution or a special refrigerator cleaner. This will remove odors and bacteria.
Plug in the empty refrigerator and let it run for 1-2 hours without loading. When the temperature reaches the set values, you can gradually load food.
Regularly check the cleanliness of the condenser (grid) at the back of the refrigerator. Dust on it interferes with heat transfer, forcing compressors Atlant to work longer and more often, which accelerates wear.
How often do you need to defrost a two-compressor Atlant?
Models with the No Frost system rarely require manual defrosting, approximately once a year or as needed (ice appears). Models with a drip system in the freezer - every 4-6 months.
Is it possible to defrost only one chamber?
Yes, in two-compressor models this is possible. Turn off one temperature control while leaving the other on. However, open the door of the operating chamber less often so as not to disturb the temperature regime.
What to do if the refrigerator does not freeze after defrosting?
Wait 2-3 hours. If it is not cold, check that the doors are closed tightly and that the operation indicator is on. If the problem persists for more than 5 hours, the refrigerant may have been damaged when cleaning the ice.
Why does a lot of ice form if there is No Frost?
Causes: the door is not tightly closed, a damaged seal, frequent opening in a hot room, or a malfunction of the defrost sensor/heating element.
Do the seals need to be lubricated?
Yes, once every six months it is recommended to wipe the rubber seals with glycerin or silicone grease. This preserves their elasticity and prevents cracks.
