Modern household appliances of the brand Atlant are deservedly popular due to their reliability, but even the most advanced models require periodic maintenance. Many owners mistakenly believe that systems No Frost or Frost Free completely eliminate the need to defrost equipment, but this is not entirely true. Although an ice crust does not form on the walls of the chambers, the evaporator needs to be cleaned, and the rubber seals need to be prevented.
The process of preparing the unit for defrosting or putting it into a special maintenance mode requires strict adherence to the sequence of actions. Improper handling of electronics or ignoring certain steps can lead to failure compressor or temperature sensors. In this article, we will look in detail at how to safely prepare your refrigerator for this procedure, regardless of what defrosting system is installed in it.
It is worth noting that by the term “put on defrost” users often understand two different actions: either a full shutdown cycle for cleaning, or activation of a special service mode in electronically controlled models. We will consider both options, paying special attention to the nuances of working with digital controllers that control refrigerant circulation.
Features of defrosting systems in Atlant refrigerators
Before taking active steps, you need to clearly understand what type of equipment you are dealing with. Equipment Atlant is produced with various modifications of defrosting systems, and the approach to each of them has its own technical features that affect preparation.
In classic models with drip system (sometimes called a “crying evaporator”), moisture flows down the back wall into gutter and evaporates. Here, “put on defrost” means forcibly turning off the compressor and allowing the ice to melt naturally. In more complex units with a system No Frost defrost occurs automatically using a timer, heating the evaporator.
⚠️ Attention: An attempt to manually start the defrost cycle on models without the appropriate control function may reset the temperature settings. Always check the technical documentation.
Electronic control allows in some models to initiate a diagnostic mode, which turns on the evaporator heating elements. However, for ordinary household cleaning this is rarely required and is more often used by service engineers when diagnosis of faults. It is more important for the owner to properly prepare the device for a scheduled wash.
- 🧊 Drip system: requires manual shutdown and waiting for the natural melting of ice on the back wall.
- 💨 No Frost: ice is not visible (hidden behind the panel), but requires periodic complete defrosting for hygiene and cleaning hidden channels.
- 🔧 Combined: In the refrigerator compartment there is a “crying” wall, in the freezer there is No Frost, which dictates different rules of care.
Understanding the type of your system will help you avoid unnecessary actions. For example, in models with Full No Frost there is no point in scraping the walls with a knife, since there is simply nothing to melt in the visible part, but dirt and bacteria can accumulate in the air ducts.
Preparing the refrigerator for the defrosting procedure
Quality preparation is 80% of the success of the entire operation. Before you begin the process, which is often called “defrosting,” there are a number of preparatory steps that need to be completed. This will ensure the safety and security of the products.
The first step is always to completely disconnect the device from the power supply. Simply turning off the button is not enough; if the model does not have such a function, it is better to unplug it power cord from the socket. This will eliminate the risk of accidentally turning on the compressor during maintenance.
☑️ Preparation for defrosting
Next you should free up the internal space. All products must be removed, and removable elements - shelves, trays, drawers - taken out. It is more convenient to wash them separately in warm water using mild detergents that do not contain abrasive particles.
It is important to prepare a place for collecting melt water. If your model Atlant has a special removable condensation tray, make sure it is installed correctly and is empty. In older models or with a large amount of ice, additional towels or shallow basins installed in front of the doors may be needed.
| Preparation stage | Action | Importance |
|---|---|---|
| Power off | Removing the plug from the socket | Critical |
| Releasing | Removing products and shelves | High |
| Floor protection | Place rags at the feet | Medium |
| Temperature mode | Waiting for temperature equalization | High |
Don't forget to spread there are old towels or rags on the floor around the refrigerator. Even with careful defrosting, water can leak out, especially if the drainage channels are cleaned with a brush. This will save your floor covering from swelling.
Action algorithm for models with electronic control
Owners of modern models Atlant with a display on the door often wonder whether it is possible to start defrosting through the menu. In most household series, this function is not available directly, since it is a service option. However, proper operation of the control panel is necessary.
If your goal is simply to defrost the unit, then on models with electronics you just need to press the off button (if there is one) or simply turn off the power to the device. The electronic control unit (module) will independently record the power outage and, when turned on again after a certain time (usually 10-15 minutes), will start the normal operating cycle.
There is a nuance with models that have the “Vacation” or “Eco” function. Make sure these options are turned off before defrosting. Being in the “Vacation” mode can change the operating algorithm of Defrost heating elements or fans, which is undesirable during maintenance.
In some rare cases, due to sensor errors, the refrigerator may “freeze” in defrost mode. If after turning on the device does not cool, but the fan is noisy, the cycle may be broken. In this case, a full cycle helps: unplugging for 30-40 minutes, then turning on. This will reboot controller and clear errors.
⚠️ Attention: Control panel interfaces may vary depending on the year of manufacture. If you are not sure of the purpose of the buttons, it is better not to experiment with the settings, but to use the physical shutdown method.
After defrosting and turning on is completed, the electronics may not show the real temperature for some time (up to 2-3 hours), operating in intensive mode. This is normal behavior for inverter compressors and precision control systems.
Manual defrosting and cleaning process
When the refrigerator is turned off and prepared, the main stage begins. For models Atlant with a drip system or mixed type, it is important to let the ice melt on its own. Using a hair dryer or hot water to speed up the process is strictly not recommended.
Sharp temperature changes can damage the plastic internal circuit chambers or cause deformation of the evaporator. Warm air from the room will do its job itself. Typically the process takes from 4 to 8 hours, depending on the thickness of the ice crust.
While defrosting is in progress, it’s time to start cleaning hard-to-reach places. Use a soft sponge and a weak solution of soda or a special refrigerator cleaner. Pay special attention to the drainage hole in the refrigerator compartment.
- 🧼 Cleaning the gutter: Carefully clean the water drainage channel using a cotton swab or a special brush.
- 🚿 Washing: pour a little warm water into the hole to make sure it flows freely into the container under the compressor.
- 🌬️ Ventilation: leave the doors open to completely dry and eliminate odors.
What should you not wash your refrigerator with?
Never use aggressive chemicals, acetone, gasoline or abrasive powders. They can damage the plastic coating of the chambers and rubber seals, making them brittle.
After all the ice has melted, thoroughly wipe all surfaces dry. Moisture inside is a potential source of new ice crust and unpleasant odor. Make sure that there is no water left in the recesses and behind the drawers.
Starting the refrigerator after defrosting
Proper starting after defrosting is no less important than the preparation itself. Sudden load on the cooling system can be stressful for the equipment. After you have washed everything and wiped it dry, put the shelves and drawers back in place.
Plug in the device. If the model is equipped with an audible signal or a flashing temperature indicator, do not be alarmed - this means that the process of gaining cold is in progress. It is better to keep the doors closed at this moment.
Do not load food right away. Let the refrigerator Atlant run idle for at least 1-2 hours so that it reaches the set temperature parameters. Only after this can you gradually fill the chambers with products.
Check the operation of the thermostat. If you have a manual control, the knob should be in the middle position (usually number 3 or 4). For electronic control, return to standard settings: +4°C for the refrigerator compartment and -18°C for the freezer.
Typical errors when servicing equipment
Even experienced users sometimes make mistakes that can shorten the life of the equipment. Knowing these nuances will help you avoid costly repairs in the future. Often problems arise due to haste or the use of inappropriate tools.
One of the most common mistakes is using sharp objects (knives, screwdrivers) to chip ice. In refrigerators Atlant the evaporator is often located very close to the inner wall or even built into it. One awkward movement can lead to depressurization of the system and leakage refrigerant.
Another mistake is ignoring the drainage system. If you do not clean the water drainage hole, a “plug” of dirt and mold will form there. The water will stop draining and will begin to accumulate at the bottom of the refrigerator compartment, and then flow out onto the floor.
⚠️ Attention: Never leave the refrigerator to defrost with the doors closed unattended for a long time. This can lead to the growth of bacteria and the appearance of a persistent musty odor.
It is also a mistake to turn on the appliance immediately after defrosting without checking dryness. Moisture on electrical contacts or in the compressor area may cause a short circuit. Always check that all surfaces are dry.
Frequently asked questions (FAQ)
How often do you need to defrost the Atlant No Frost refrigerator?
Models with the No Frost system do not require frequent defrosting to remove ice, since it does not form. However, for hygienic purposes and cleaning from bacteria, it is recommended to carry out complete defrosting and washing 1-2 times a year.
Is it possible to speed up defrosting with a hair dryer?
The use of a hair dryer is not recommended by manufacturers. The flow of hot air can unevenly heat the plastic, causing it to deform, or damage the sensitive temperature sensors inside the chamber.
What to do if the refrigerator does not turn on after defrosting?
Check for voltage in the outlet. Make sure the door is tightly closed (on some models the light only comes on when the door is open, but this does not affect starting). If you hear a click but do not start, wait 15-20 minutes - the compressor protection may have tripped.
Do you need to lubricate the seals after defrosting?
Yes, this is a useful procedure. Wipe the rubber seals with glycerin or special silicone grease. This will maintain their elasticity and ensure a tight fit of the door, which is critical for energy efficiency.
Why does it take a long time for the cold to accumulate after defrosting?
This is a normal process. After defrosting, the walls of the chamber are warm, and the system takes time (from 2 to 6 hours depending on the model) to cool the entire volume. Do not load food during this period.
