The operation of household appliances requires strict adherence to maintenance regulations, especially when it comes to complex cooling systems. The brand's two-compressor models Atlant are deservedly popular due to their reliability and the possibility of independent operation of the refrigeration and freezer chambers. However, even the most advanced units with a No Frost system or combined cooling require periodic shutdown for preventative maintenance and deep cleaning.
Improper power management can lead to failure of expensive compressor components or compromised system tightness. Unlike single-circuit models, it is critically important to understand the logic of the operation of thermostats and electronic units. Full defrosting It requires not just unplugging the cord from the socket, but performing a series of preparatory steps, which will be discussed below.
Owners often wonder whether it is possible to defrost only one camera, leaving the second one to work. The answer depends on the specific modification and type of refrigerant, but the general safety principles are the same for the entire line. Next, we will analyze in detail the algorithm of actions that will allow you to carry out the procedure without risk to the equipment.
The principle of operation of the Atlant two-compressor system
The fundamental difference between such models is the presence of two independent refrigerant circulation circuits. Compressors In this scheme they work autonomously: one serves the refrigeration compartment, the second - the freezer. This allows you to set different temperatures in the chambers and defrost one of them without losing food in the other, which is a key advantage over single-circuit analogues.
Each unit is controlled through its own thermostat or electronic module. When you initiate a defrost, it is important to consider that heat flow can be transferred through the partitions, especially in models without fully insulated chambers. Therefore, even when one compressor is operating, the second circuit may heat up faster than usual.
⚠️ Attention: In some older modifications Atlant evaporators may be partially connected. Before starting work, make sure that your model supports independent defrosting of the chambers by checking the technical documentation.
The electronics of modern models are capable of starting defrost cycles themselves, but mechanical shutdown is required for manual washing and disinfection. Understanding the physics of the process helps to avoid mistakes when the user tries to speed up the process by using a hairdryer or hot water, which is strictly prohibited.
Preparation of equipment for the shutdown procedure
The process should begin long before the physical break of the power supply circuit. The first step will be to empty the chambers of food. Frozen stocks it is better to transfer them into containers with ice or another cold place in advance to minimize equipment downtime. This is especially true for the freezer, where the temperature drops more slowly when the compressor of the adjacent circuit is turned on.
Next, you need to remove all removable elements: shelves, drawers, egg trays and bottle holders. Plastic parts become brittle at low temperatures, and a sharp temperature change during washing can damage them. Glass shelves Also require caution - do not place them immediately under hot water after the freezer.
Prepare absorbent materials. Rags, towels or special absorbent diapers will be needed to collect melt water. In two-compressor models Atlant the drainage system may not be provided structurally, and water will accumulate at the bottom of the chambers or flow out.
☑️ Preparation for defrosting
It is important to check the condition of the rubber seals on doors before starting work. If they have cracks, they may become more visible as they defrost. Cleaning the seals from plaque is an obligatory part of the preparation, which will ensure tightness after switching on.
Algorithm for disconnecting the refrigerator from the network
The most crucial moment is the correct termination of the operation of the compressors. In dual-compressor models Atlant the power buttons can be located differently: on the body, inside the chamber, or absent altogether. If your model has mechanical switches, they must be set to 0 or Off.
After turning the switches to off mode, wait 1-2 minutes. This time is necessary to equalize the pressure in the system and stop the oil circulation. Only after this pause can you remove the plug from the socket. Abruptly cutting off power to an engine running at high speeds can shorten its life.
If the model is equipped with electronic control, the procedure may differ. Sometimes you need to hold down a combination of buttons to enter the service mode or simply turn off the power using the button on the panel and then disconnect the cord. Electronic module is sensitive to power surges, so you should also be careful when turning it on after defrosting.
⚠️ Attention: Never pull the refrigerator by the wire or door to access the outlet. This may damage the cable or disrupt the geometry of the case.
In some cases, when access to the outlet is difficult, it is permissible to use a surge protector with an off button, but only if it is designed for high inrush currents. It is better not to use standard household extension cords for powerful equipment like Atlant Atlant
The process of natural defrosting of the chambers
After the shutdown, the longest stage begins - the melting of the ice. In two-compressor systems, this process may proceed unevenly. The chamber that worked more intensively will defrost longer. Natural defrosting is the only safe method for the (evaporator) hidden behind plastic panels.
It is strictly forbidden to use sharp objects to chip ice. The aluminum evaporator tubes in the models Atlant are located very close to the surface, and it is easier to pierce them with a knife than it seems. Damage to the tube will lead to freon leakage and expensive repairs.
To speed up the process, you can place containers with warm (not hot!) water inside the chambers. Close the doors to prevent heat from escaping. After 15-20 minutes, the water needs to be replaced, as it cools down quickly. This method is safer than using hair dryers, which can melt the plastic or damage the wiring.
| Defrost method | Safety for the evaporator | Process speed | Risk for plastic |
|---|---|---|---|
| Natural melting | High | Low (4-8 hours) | Absent |
| Warm water in a container | High | Medium (2-4 hours) | Minimum |
| Hair dryer (warm air) | Medium | High (30-60 min) | High |
| Mechanical chipping | Critical low | High | High |
Why Can’t you use a hairdryer at maximum power?
A hot stream of air can cause local overheating of the plastic, leading to its deformation. In addition, condensation formed during sudden cooling of hot air can get onto the electrical contacts, causing a short circuit the next time you turn it on.
Moisture removal and disinfection
When the ice has completely melted, it is necessary to carefully remove the water. In two-compressor models Atlant a drainage hole is often located on the back wall of each chamber. Clean it with a special soft brush or brush to ensure free flow of condensate in the future.
To wash the internal surfaces, use a weak soda solution or a special product for household appliances. Aggressive chemicals, containing acids or abrasives, can damage the coating of the chambers and cause corrosion metal parts. After treatment, all surfaces must be wiped dry with a clean rag.
Pay special attention to the area around the compressors, which is located in the lower rear part of the unit. Dust may accumulate there, impairing heat transfer. Carefully vacuum the radiator grill without touching the tubes and wires.
After washing, leave the doors ajar for 2-3 hours for complete drying and ventilation. This will prevent mold from growing in hard-to-reach corners and on seals. Make sure that there is no draft in the room that could warp the doors.
Proper switching on after defrosting
Starting the refrigerator Atlant after defrosting requires observing a time interval. The motor-compressor must “stand” for at least 2 hours after defrosting so that the oil flows into the crankcase and the refrigerant is distributed throughout the system. Switching on “hot” can lead to water hammer.
Connect the cord to the outlet and set the thermostats to the middle position. Do not load the chambers with products immediately. Let the equipment run idle for 1-2 hours until the operating temperature is established. Indicators on the panel (if any) will tell you when the temperature has reached normal.
First load should be gradual. Do not add large quantities of warm food at once, this will force the compressors to work at their limit. In two-compressor systems, the load can be distributed: first fill one chamber, then, after an hour, the second.
⚠️ Attention: If after turning on you hear an unusual noise, knocking or humming, immediately disconnect the device from the network. This may indicate incorrect installation or technical malfunctions.
Frequent errors when servicing equipment
One of the common mistakes is trying to defrost only freezer, leaving the refrigerator running. In two-compressor models this is technically possible, but not always advisable. Temperature differences across the partition can lead to condensation inside the housing and corrosion.
Another mistake is ignoring cleaning the drainage system. Water stagnating in the pan above the compressor evaporates, leaving a salt deposit that corrodes the metal over time. Regular cleaning drain hole extends the life of the unit.
Some users try to speed up the process by opening windows in winter to freeze the refrigerator. This is a big mistake. Sudden changes in temperature and humidity can damage electronics and lead to cracking of plastic.
Is it possible to defrost a refrigerator if the family has left?
Yes, this is the ideal time. However, make sure that water does not leak onto the floor. Cover the floor around the refrigerator with rags or place wide trays. If defrosting takes more than a day, check the condition of the water.
What to do if after defrosting the refrigerator does not freeze?
Check whether the doors are tightly closed and whether the thermostats are installed correctly. If the temperature does not drop within 3-4 hours, the circuit may have been damaged during defrosting or an electronic failure may have occurred. A call from a technician is required.
How often do you need to defrost the two-compressor Atlant?
Models with the No Frost system do not need defrosting, only a hygienic wash once a year. Models with a drip system or manual defrosting require the procedure 1-2 times a year, or when an ice crust forms more than 5 mm thick.
