Modern household appliances of the brand Atlant are deservedly popular due to their reliability and functionality. However, even the most advanced models, especially two-chamber units with two independent compressors, require regular maintenance. Many owners are faced with a dilemma: how to properly stop the operation of such a complex device in order to carry out high-quality defrosting and not damage the system.
Unlike old single-compressor models, where everything depended on one thermostat, a two-compressor scheme involves independent operation of the freezer and refrigeration chambers. This creates certain nuances in the service process that must be taken into account. Incorrect actions can lead to a reduction in service life refrigerant or damage to the compressor equipment.
In this article we will analyze in detail the algorithm of actions that will allow you to safely turn off your refrigerator for routine cleaning. You will learn why you cannot simply unplug the cord from the socket while the motor is running and how to avoid common mistakes that inexperienced users often make when first encountering a dual-circuit system.
The principle of operation of a dual-compressor system
To understand how to properly manage defrosting, you need to at least superficially understand the structure of your unit. A two-chamber refrigerator Atlant with two compressors technically represents two independent refrigeration circuits combined in one housing. One motor is solely responsible for the freezer compartment, and the second is responsible for the refrigerator compartment.
This design has its advantages, for example, more precise temperature control and the ability to turn off one of the chambers without losing cold in the other. However, during defrosting, this creates a situation where one compressor can work while you are trying to defrost the second part of the unit. Thermoregulator Each chamber controls its own circuit independently.
That is why the standard shutdown by turning the temperature regulator to zero may not be effective or fast enough if you want to stop the entire process generating cold instantly. Understanding this independence of circuits is the key to proper operation.
⚠️ Attention: Attempting to quickly switch temperature controls back and forth to stop the compressors can lead to electronic failures or mechanical sticking of thermostat contacts.
Preparing for the defrost procedure
Before taking active steps to disable the equipment, it is necessary to carry out a number of preparatory work. This will minimize the risk of food spoilage and simplify subsequent cleaning. First of all, assess the amount of frozen and refrigerated food.
If there is a lot of food in the cells that cannot be thrown away, prepare thermal containers, ice packs in advance, or ask your neighbors to temporarily store some of the supplies. Two-compressor models Atlant keep cold for a long time, but without food, food will begin to deteriorate in a few hours.
- 🧊 Defrost the ice in molds in advance to use it for packing food warmly.
- 📦 Prepare basins and rags to collect water, since two-chamber systems produce a lot of condensation.
- 🧹 Free up space around the refrigerator for easy access to the back wall.
It is also important to clear shelves and drawers of easily breakable dishes. Vibration when removing shelves during defrosting can be dangerous. Make sure the floor around the unit is dry to avoid the risk of slipping or water getting on electrical parts.
Algorithm for completely shutting down the refrigerator
The most important stage is the correct sequence of actions to stop the operation of the unit. For two-compressor models Atlant there is a clear order, violation of which is undesirable. First, you need to stop the cooling process programmatically, and only then physically.
Find temperature regulators. Depending on the model Atlant, these may be rotary mechanical handles inside the cameras or an electronic control panel on the door. If you have a manual one, turn the knobs to the “0” or “Off” position. This will break the electrical power supply circuit of the compressors.
After you have set the controls to the off position, wait 1-2 minutes. This time is necessary for the refrigerant in the system to stabilize and the pressure to equalize. Only after this pause can you safely remove the plug from the socket.
☑️ Safe disconnection checklist
If you simply pull out the cord without stopping the compressors through the regulator, the next time you turn it on (or if you accidentally insert the cord back), the motor may start under load. For start relay this is a stress factor that reduces the resource.
Nuances of defrosting two circuits
The defrosting process in a two-compressor refrigerator has its own characteristics. Since the chambers are isolated from each other not only by a partition, but also by independent cooling systems, the ice can melt at different rates. The freezer usually takes longer.
Do not try to speed up the process by using a hairdryer or hot water, especially if you have a model with a system No Frost in one of the chambers. Sudden temperature changes are dangerous for plastic parts and evaporators. Natural melting is the safest option.
Pay special attention to water drainage channels. In two-chamber models Atlant drainage holes can be located in different places in each chamber. They must be cleaned with a soft syringe or brush so that water does not stagnate inside the housing.
| Parameter | Refrigerator compartment | Freezer compartment |
|---|---|---|
| Time defrosting | 2-4 hours | 6-10 hours |
| Presence of an evaporator | Open or hidden | Most often closed |
| Temperature | +2...+5 °C | -18...-24 °C |
| Risk of damage | Medium | High (with mechanical cleaning) |
Care of equipment during downtime
While your refrigerator Atlant is unplugged, it’s time to do some spring cleaning. Use mild detergents that do not contain abrasive particles. Aggressive chemicals can damage the coating of the internal walls and sealing rubber bands.
Be sure to check the condition of the seals on the doors. In dual-compressor models, the tightness of each chamber is critical to the efficient operation of (each) circuit. Wipe the rubber bands with a soda solution or a special rubber care product.
⚠️ Attention: It is strictly forbidden to use sharp objects (knives, screwdrivers) to chip ice. Damage to the evaporator tubes will lead to freon leakage and expensive repairs.
After washing, thoroughly wipe all surfaces with a dry cloth. Moisture should not remain anywhere, especially in hard-to-reach corners and around shelf mounts. Allow the unit to dry completely before turning it on.
Proper turn-on after defrosting
The final stage is putting the refrigerator into operation. There are also rules here. Don't rush to load products right away. First, make sure that the unit is completely dry and assembled.
Plug the plug into the outlet. Make sure the outlet contacts are tight and do not spark. Only after connecting the power switch the temperature controllers from position “0” to operating mode. For Atlant usually this is position 3 or 4.
Let the refrigerator run idle for at least 2-3 hours. During this time, it will reach the required temperature, and the automation will turn off the compressors. Only after the first cooling cycle can you load food.
