Owners of a modern household appliances, people often wonder whether a refrigerator equipped with a defrosting system generally needs to be defrosted. Marketing slogans promise a complete absence of ice and the need for manual intervention, but actual operation makes its own adjustments. Despite the presence of an air damper and an evaporator hidden behind the panel, a thin layer of frost still forms inside the chamber, and moisture can accumulate at the bottom. No Frost. Marketing slogans promise a complete absence of ice and the need for manual intervention, but actual operation makes its own adjustments. Despite the presence of an air damper and an evaporator hidden behind the panel, a thin layer of frost still forms inside the chamber, and moisture can accumulate at the bottom.
For equipment of the Belarusian brand Atlant maintenance regulations require periodic hygiene procedures. This is necessary not only to maintain cleanliness, but also to extend the life of the compressor and air circulation system. Ignoring this process can lead to the appearance of foreign odors and a decrease in cooling efficiency.
In this article we will analyze in detail the algorithm of actions that will allow you to safely and quickly put your unit in order. We will look at time intervals, necessary tools and common mistakes that users make when trying to speed up the ice melting process.
Features of the No Frost system in Atlant refrigerators
The principle of operation of the system No Frost (translated as “no frost”) is based on forced circulation of cold air. Unlike static models, where the cold comes from the walls of the evaporator, here the air is driven by a fan through a hidden heat exchanger. In two-chamber models Atlant this process is often organized in such a way that the cold from the freezer compartment is transferred to the refrigerator compartment through a special channel.
It would seem that with this design, ice should not form at all. However, moisture in food, opening doors and the entry of warm air lead to condensation. The system automatically defrosts the evaporator, but the water does not always have time to completely evaporate or goes into the drainage, settling on the internal surfaces of the chamber in the form of a thin crust. Over time, this crust thickens.
In addition, the ventilation holes in the air circulation system may become clogged. If they are not cleaned, heat exchange is disrupted and the compressor is forced to work with increased load. That is why even for advanced models Atlant a periodic complete shutdown is required for sanitary treatment.
Why does ice form in No Frost?
In the No Frost system, ice forms on a hidden evaporator. During normal operation it melts and evaporates. However, if doors are frequently opened or there is high humidity in the room, moisture can settle on products and shelves, creating a visible layer of frost, which the system does not remove automatically.
How often should you defrost the refrigerator
The manufacturer Atlant in the technical documentation indicates that complete defrosting is not required as often as in older models with a drip system. The optimal interval is once every 6–12 months. However, this period may be shortened depending on operating conditions.
If you notice that the refrigerator starts to work louder, does not turn off longer, or an unpleasant odor appears inside, the procedure should be carried out immediately. Also, the reason for unscheduled cleaning is the formation of a noticeable ice crust on the back wall or on the shelves.
The frequency of defrosting depends on several factors:
- 🧊 Frequency of opening the doors: the more often you look inside, the more moist air enters the chamber.
- 🥩 Type of loaded products: open containers with liquid and foods with a high water content (vegetables, fruits) increase humidity.
- 🌡️ Room temperature: in a hot kitchen, the load on the cooling system is higher, which can lead to faster frost formation.
Preparation for the defrosting process
Before starting the procedure, it is necessary to properly prepare the equipment and free up the space around it. You should not start the process if you have a large supply of frozen food in the freezer that has nowhere to put it. Take care in advance to temporarily place supplies in a cool place or use thermal bags.
The first step is always to completely disconnect the device from the power supply. Unplug the cord from the outlet. This is critical for safety, as water used in cleaning and electrical current are a dangerous combination. In addition, when defrosting, a running compressor will try to increase the temperature, wasting energy.
Next, you need to empty the chambers of the contents:
- ❄️ Remove all products, sorting them by storage temperature.
- 🗄️ Remove all removable elements: shelves, drawers, egg trays, shelves on the doors.
- 🧹 Prepare a container for washing removable parts and detergent.
☑️ Preparation checklist
It is better to immediately wash removable plastic and glass elements with warm water and a mild detergent and leave dry. Do not use hot water on glass to avoid temperature shock and cracks. While the shelves are drying, you can begin the main thawing process.
Natural defrosting: step-by-step algorithm
The safest and recommended method of defrosting is natural. It does not require the use of additional tools and eliminates the risk of damaging the camera's internal coating or plastic parts. For a two-chamber Atlant this process takes from 4 to 10 hours, depending on the amount of ice and the temperature in the room.
After you have removed the food and shelves, leave the refrigerator and freezer doors completely open. This will provide an influx of warm air and start the melting process. Under the lower edge of the freezer and refrigerator compartment, as well as in front of the doors, it is necessary to place well-absorbing rags or place flat containers.
Water will drain by gravity. In models with No Frost the main volume of water is usually collected in a special groove at the bottom of the freezer and goes through the drainage channel into the evaporation tank above the compressor. However, if the system is clogged or there is a lot of ice, water may flow out, so control is required.
⚠️ Attention: It is strictly forbidden to use sharp objects (knives, screwdrivers, scrapers) to chip ice. The internal walls of the refrigerator Atlant are made of thin plastic, behind which there are tubes with refrigerant. One careless movement can lead to depressurization of the system and costly repairs.
During the melting process, it is recommended to periodically wipe the walls with a dry rag, removing softened ice. This will speed up the process. Do not leave water standing inside the chamber for a long time, as it may freeze again if the room is cold, or promote the growth of bacteria.
Comparison of defrosting methods
There are several approaches to removing ice, but not all of them are equally useful for technology. Below is a table comparing the main methods in terms of safety and efficiency for refrigerators Atlant.
| Method | Safety | Speed | Risk of damage |
|---|---|---|---|
| Natural defrosting | High | Low (4-10 hours) | None |
| Hair dryer (warm air) | Average | High | Plastic melting, overheating of sensors |
| Hot water in containers | High | Average | Minimum (risk of glass cracks) |
| Mechanical cleaning | Low | High | Critical (puncture contour) |
As can be seen from the table, the natural method is the gold standard. Using a hairdryer is permissible only in extreme cases, when time is limited, but the air stream must be directed strictly at the ice, avoiding contact with rubber seals and plastic control panels. The air temperature should not be too high.
Mechanical cleaning with a knife or icebreaker is a recipe for failure. Even if it seems to you that you are acting carefully, plastic becomes brittle at subzero temperatures, and the risk of chips or cracks increases many times over. Repairing the evaporator is often not economically feasible.
Sanitary treatment and care after defrosting
After all the ice has melted and the water has been removed, the washing stage begins. Even if the refrigerator is visually clean, bacteria could have multiplied inside and caused the smell. Use a weak solution of soda, vinegar, or a specialized product for household appliances.
Wipe all internal surfaces thoroughly, paying special attention to corners, panel joints and rubber seals on the doors. It is in the folds of rubber that mold and dirt most often accumulate. For hard-to-reach places, you can use a soft toothbrush or cotton swabs.
Pay special attention to the drainage hole. In two-chamber Atlant it is often located on the back wall of the refrigerator compartment or in the corner of the freezer. It must be carefully cleaned to ensure free flow of condensate in the future. To do this, you can use a soft brush or a twisted bundle of cotton wool.
After washing, all surfaces should be wiped dry with a clean cloth. Leave the doors open for another 30-60 minutes for final drying and ventilation. Only after this can dry shelves and drawers be installed back.
Starting the refrigerator and typical errors
The final stage is turning on the device. You should not download products immediately after connecting to the network. Let the refrigerator Atlant run idle for at least 2-3 hours (for some models up to 6 hours) until it reaches the desired temperature and turns off automatically.
Loading warm food into a chamber that has not cooled down will cause the compressor to work at maximum load, which is harmful to the motor. First, make sure that a stable cold mode has been established inside.
Common mistakes that users make:
- 🚫 Using boiling water: pouring boiling water on ice is not allowed, a sudden temperature change can damage the plastic and cause deformation of the panels.
- 🚫 Ignoring the instructions: try defrosting only one chamber (if the design does not allow this to be done in isolation) will lead to an imbalance of temperatures.
- 🚫 Starting with water: starting the compressor while there is still water inside or the walls are not dry can lead to a short circuit.
⚠️ Attention: If, after defrosting and turning on, the refrigerator makes unusual sounds, does not cool, or ice quickly forms on the back wall again, this may indicate a malfunction of the thermostat, a freon leak, or a breakdown of the defrost system. In this case, diagnostics by a specialist is required.
Following these simple rules will allow your refrigerator Atlant to serve for many years, keeping food fresh and energy saved. Regular maintenance is the key to the smooth operation of complex equipment.
Is it possible to defrost a refrigerator without unplugging it?
No, it is not possible. Defrosting involves turning off the power. A running compressor will try to compensate for the heat from the melting ice, which will lead to overload and increased energy consumption. In addition, it is unsafe when using water for washing.
How long does it take to defrost Atlant No Frost?
Usually the process takes from 4 to 10 hours. The time depends on the thickness of the ice layer, the room temperature and the number of doors open. Do not try to artificially speed up the process with aggressive methods.
What to do if a smell appears after defrosting?
It is necessary to re-wash all surfaces with a solution of soda or vinegar. Pay special attention to the drainage hole and rubber seals where stagnant water could remain. Also check whether water has entered the thermal insulation layer (which is unlikely if defrosting is done correctly).
Is it necessary to defrost an Atlant refrigerator with a drip system?
Yes, models with a drip system (crying wall) require defrosting more often - about once every 3-6 months, since ice forms in them on the back wall of the refrigerator compartment and periodically chips, requiring removal of moisture from the tray.
