Owning Belarusian-made household appliances requires the owners to understand the specifics of their maintenance. This is especially true for classic models with two compressors, where the cooling systems are structurally separated. Many users mistakenly believe that having two separate motors allows them to ignore regular defrosting, but this is not the case. An ice crust can disrupt heat transfer and increase energy consumption significantly.
The process of removing ice in brand units Atlant has its own technological nuances that distinguish it from servicing single-compressor analogues or No Frost systems. The dual-circuit design means that the evaporators of the refrigeration and freezer chambers operate independently of each other. That is why the approach to maintenance must be phased and consistent. Ignoring this rule can lead to breakdown of the thermostats or failure of one of the compressors.
In this article we will analyze in detail the algorithm of actions that will allow you to safely and effectively clear the chambers of ice. You will learn why you shouldn’t rush, how to properly prepare your equipment, and what tools you may need. Compliance with simple operating rules will extend the life of your refrigeration equipment and preserve the quality of products.
Before taking active steps, it is necessary to assess the current condition of the unit. If the thickness of the ice crust on the walls of the freezer exceeds 5-7 millimeters, the procedure can no longer be postponed. In two-chamber models with two motors, this situation often occurs unevenly: in one compartment there may be more ice due to frequent opening of the door or a loose seal.
The principle of operation of a dual-circuit cooling system
Understanding the internal structure helps to avoid fatal errors during maintenance. Unlike monoblock systems, where one compressor drives freon through both circuits, two independent units are installed here. One motor is responsible for low temperatures in the freezer, and the second maintains positive mode in the refrigerator compartment. This provides more stable temperatures, but doubles the number of potential points of failure if used incorrectly.
When you turn off the power, both compressors stop at the same time. However, the process of ice melting in different chambers can proceed at different speeds due to the difference in initial temperatures and the volume of heat inflow. An attempt to accelerate the melting process by external influence can lead to damage to fragile tubes or the evaporator itself.
A design feature Atlant is the location of the temperature sensors. They control the heating of the motors and the temperature in the chambers. If there is a thick layer of ice, the sensors can transmit distorted data, causing the equipment to run idle. The two-compressor circuit is good because it allows you to defrost the chambers one at a time, although a full cycle of turning off the power is still the preferred method for high-quality cleaning.
⚠️ Attention: In models with two compressors, it is strictly forbidden to turn off only one of the motors, trying to defrost one chamber while the other is running. This will lead to overload of the operating circuit and possible failure of the control system.
The refrigerant circulation in such systems is organized in such a way that each circuit has its own capillary pipeline and its own filter-drier. The disruption of heat transfer due to ice in one circuit should not (affect) the other, but in reality, the thermal conductivity of the housing materials makes its own adjustments. Therefore, completely stopping the system is the only safe way to restore the factory heat exchange parameters.
Preparing for defrosting: step-by-step algorithm
The beginning of the process requires careful preparation in order to minimize stress for equipment and inconvenience for household members. The first step is to free up the internal space. All products must be removed from the chambers. If it is winter outside, they can be taken out to the balcony, but only if the temperature there does not fall below the permissible storage values, otherwise the products will spoil. In the summer, you will have to use thermal bags or ask your neighbors to temporarily place supplies.
Next, you should disconnect the unit from the power supply. To do this, you need to unplug the plug from the socket. Some models Atlant equipped with a power button on the case, but physically breaking the circuit through the outlet is a prerequisite for safety. After this, open the doors of both chambers and let the interior space ventilate. This will help to quickly equalize the temperature and remove unpleasant odors.
Preparing the floor around the equipment is a critically important stage. Melt water can flow under the baseboards or get on the laminate, causing it to swell. Prepare several large rags, sponges and basins in advance. If your model has a water drainage channel, make sure it is not clogged with debris and prepare a container to collect liquid.
- ❄️ Clear shelves and drawers of food by packing perishable items in thermal bags.
- 🔌 Unplug the power cord from the outlet, making sure it is dry hands.
- 🧹 Cover the floor around the refrigerator with absorbent rags or towels.
- 🚪 Open the doors of both chambers as wide as possible, fixing them if necessary.
While the equipment is turned off, it’s time to inspect the rubber seals. They should not have cracks, tears or sticky residue. Dirt on the magnetic tape breaks the seal, which leads to increased ice formation. Wipe the seals with a soft cloth dampened in a mild soap solution and wipe dry. This is a simple but effective preventive measure.
Do not forget to remove all removable elements: shelves, vegetable trays, plastic containers. It is better to wash them separately in the bathroom under running water. Plastic may crack due to a sharp temperature change (if washed with hot water in the cold), so let the parts warm up to room temperature before contacting water.
The process of natural defrosting of chambers
The safest method recommended by manufacturers is the natural melting of ice. In two-chamber Atlantakh with two compressors, this process can take from 6 to 12 hours, depending on the thickness of the ice and the room temperature. You should not try to speed things up by using hair dryers or heaters, as this can lead to deformation of the plastic elements and damage to the evaporator tubes.
During the melting process, water will flow into special channels or simply drip to the bottom of the chamber. Your task is to remove the liquid in a timely manner. If the model is equipped with an external water drainage system, check whether the hose is kinked. In classic models, water will have to be scooped out with a mug or wiped with a sponge as it accumulates. The main thing is to prevent water from overflowing over the edge of the door threshold onto the floor.
Pay special attention to hard-to-reach places: the corners of the chamber, the space behind the ledges for bottles and under the trays. This is where water most often accumulates, which when turned on again will turn into an ice plug. After the visible ice has melted, let the equipment stand with the doors open for another 30-40 minutes. This will allow residual moisture to evaporate and equalize the temperature of the internal walls.
☑️ Defrosting checklist
If the ice in the freezer has not melted for several hours, although the refrigeration water is already knee-deep, this may indicate a malfunction of the thermostat or problems with defrosting (if the model offers automatic defrosting evaporator). However, in most classic two-chamber Atlantov defrosting is completely manual, and (patience) is the main tool here.
After the ice has completely disappeared, you must thoroughly wipe all internal surfaces with a dry, clean cloth. The humidity inside the chambers should be minimal before switching on. The remaining moisture will instantly turn into an ice crust when the compressor starts, and the whole process will have to be repeated again.
What you absolutely cannot do
There are a number of common misconceptions about how to quickly defrost a refrigerator, which can lead to expensive repairs. The most dangerous thing is using sharp objects (knives, screwdrivers, scrapers) to chip ice. Aluminum evaporator tubes in refrigerators Atlant located very close to the inner wall of the chamber. One awkward move and the freon will come out, and repairing the cooling system will be very expensive.
The second common mistake is the use of open fire sources or powerful fan heaters aimed directly at the plastic. The plastic panels inside the chambers are not designed to withstand high temperatures. They may melt, change geometry or lose their thermal insulation properties. Even a hair dryer should be used with extreme caution, directing the air flow not at the ice, but at the walls of the chamber, and constantly changing the angle.
⚠️ Attention: Never pour boiling water directly onto an ice block. A sudden change in temperature can cause cracks in the plastic of the inner chamber or damage the glass shelves if they are installed inside.
It is also forbidden to turn on the refrigerator until the internal surfaces have completely dried. Water entering electrical contacts or wiring channels may cause a short circuit. In addition, moisture that gets into the drainage hole, when frozen, forms an ice plug, which is then extremely difficult to remove without disassembling the back panel.
You should not defrost the refrigerator if there are power surges in the network. It is better to wait for the power supply to stabilize or use a stabilizer. A sudden start of compressors after defrosting at low voltage can lead to their burnout. Two compressors create a double load on the network at the time of startup, so the quality of electricity plays an important role here.
- 🔪 Do not use knives and metal scrapers to remove ice.
- 🔥 Do not use hair dryers at maximum temperatures and heaters against plastic.
- 💧 Do not fill the chambers with boiling water to speed up the process.
- ⚡ Do not turn on the equipment until the insides are completely dry.
Ignoring these rules often leads to the fact that instead of prevention, the user gets a breakdown. Repairing an evaporator or replacing a compressor are complex procedures that require calling a technician and special tools. Simply following safety rules saves not only money, but also nerves.
fridge care after defrosting
After you have successfully completed defrosting and wiped the chambers dry, do not rush to immediately load the food. The refrigerator needs time to reach operating temperature. Plug in the unit and leave it empty for at least 2-3 hours. During this time, both compressors (in turn or simultaneously, depending on the logic of the thermostats) will reach operating mode, and the thermostats will turn them off.
During this period, it is useful to treat the internal surfaces with a weak soda solution or a special product for caring for refrigerators. This will help eliminate bacteria and unpleasant odors that may have accumulated during use. For models Atlant with plastic internal panels, products without abrasive particles and chlorine are excellent.
How to wash the inside of the refrigerator?
For washing, use a solution of baking soda (1 tablespoon per 1 liter of water) or soft soap product. Avoid harsh chemicals that can damage the plastic or leave a toxic odor. After washing, be sure to wipe the surfaces with clean water and wipe dry.
Check the operation of the drainage system. Pour a small amount of water (about 50 ml) into the condensate drain drain in the refrigerator compartment (if your model has one). The water should flow freely into a container located above the compressor at the back. If the water is standing, it means that the channel is clogged and requires cleaning with a special brush or soft wire.
It is better to load products gradually. Do not place warm food or crowd the chambers immediately after switching on. Let the equipment work in light mode to stabilize the temperature background. This is especially important for two-compressor systems, where each motor must reach its operating cycle without overload.
Regular maintenance includes not only defrosting, but also checking the cleanliness of the condenser (grid) on the rear wall. Dust and pet hair, accumulating there, impair heat transfer, forcing compressors to work longer and more intensely. Wipe the grill with a dry cloth or vacuum it every six months.
Typical problems and their solutions
Even with proper care, situations may arise that require attention. For example, after defrosting, the refrigerator does not turn on or, conversely, does not turn off. In two-chamber models with two compressors, this may be due to desynchronization of the thermostats. If one motor comes into operation and the other does not, this is normal, they work independently.
The appearance of a large amount of water on the floor after turning on may indicate that the drainage hole is frozen or clogged. In this case, you need to carefully clean it. If water appears regularly, it is possible that the door seal is broken or the seal is worn out, and warm air constantly gets inside, condensing on the cold walls.
| Problem | Possible cause | Solution |
|---|---|---|
| Refrigerator buzzes more than usual | Uneven installation or touching the walls | Align the legs, move them away from the furniture |
| One of the chambers is not freezing | Failure of one of the compressors or leakage | Call a technician for diagnostics |
| The defrost indicator is constantly on | The door is not closed tightly or the electronics are faulty | Check the seal, restart the equipment |
| There is no water inside shelves | The drainage is clogged or the products touch the back wall | Clean the drainage, move the products aside |
If after defrosting you notice that one of the compressors works continuously without turning off for more than 2-3 hours, this is an alarming signal. Perhaps there is little freon left in the system due to a micro-leak, or the thermostat has failed. Operation in this mode will quickly lead to the combustion of the motor-compressor.
⚠️ Attention: Technical characteristics and location of controls may vary depending on the specific series and year of manufacture of the Atlant refrigerator. Always check the official user manual for your model before carrying out complex operations.
Noisy operation can also be caused by vibration of pipelines. When defrosting and washing, you could accidentally touch the tubes at the back of the unit. Check that they do not touch each other or the body, and carefully separate them, if necessary, after disconnecting the device from the mains.
How often do you need to defrost a two-chamber Atlas
The frequency of defrosting depends on the intensity of use of the equipment and environmental conditions. If the room humidity is high and the door is opened frequently, ice will build up faster. Manufacturers recommend carrying out the procedure at least once a year, even if there seems to be little visible ice. The microscopic layer of ice also worsens heat transfer.
However, if you notice that the thickness of the ice crust has reached 5 mm, there is no need to wait until the end of the year. Defrost immediately. During the summer when humidity is high, this may be required every 4-6 months. In winter, when central heating is running, the air in the apartment is dry, and ice forms more slowly.
Timely defrosting is not only hygiene, but also energy saving. A layer of ice of 1 cm increases the energy consumption of the refrigerator by 15-20%. Two compressors consume more energy than one, so keeping them clean directly affects your electricity bills.
By following these simple rules, you will ensure long and reliable operation of your refrigerator Atlant. The two-compressor system is a reliable and time-tested unit that, with proper care, will serve you for decades. Do not neglect prevention, and the equipment will answer you with stable cold and food safety.
Is it possible to defrost only the freezer compartment, leaving the refrigeration chamber to work?
In two-compressor models, it is theoretically possible to turn off one circuit, but structurally this is often impossible to do without disassembling or having special switches that household models do not have. In addition, when the freezer is open, the cold will escape from the refrigerator compartment, causing the second compressor to run idle. It is easier and safer to defrost the entire unit.
What to do if an unpleasant odor appears after defrosting?
An unpleasant odor can come from stagnant water in the drain pan or from food debris in the corners. Wash all chambers thoroughly with a solution of soda or citric acid. Also check the water collection pan above the compressor at the back - perhaps organic matter has gotten in there and started to rot. Remove the tray, wash it and dry it.
Do you need to lubricate the door hinges after defrosting?
Yes, after washing and drying, it is recommended to lubricate the door hinges and seals with a special silicone grease. This will prevent the rubber from drying out and the doors squeaking. Water could wash away the factory lubricant, so restoring the protective layer will prolong the life of the closing mechanism.
Why does the Atlant refrigerator take a long time to gain temperature after defrosting?
After defrosting, the insides of the unit are heated to room temperature. It takes two compressors time (2 to 5 hours) to cool a large volume of air and walls. If you loaded a lot of warm products at the same time, the time to reach the mode will increase. Let the equipment run idle.
