Refrigeration equipment from the Belarusian plant "Atlant" deservedly enjoys the trust of consumers due to its reliability and availability. However, like any equipment, these units require proper care to maintain the characteristics declared by the manufacturer. One of the key questions that owners often ask is the frequency of defrosting. The regularity of this procedure directly affects energy consumption, the quality of freezing products and the durability of the compressor.
The frequency of defrosting depends on the specific model of your device, since the cooling system can be drip or No Frost. In the first case, deicing is a mandatory maintenance step, while in the second it is a preventive measure. Ignoring the manufacturer's recommendations can lead to a thickening of the ice crust on the evaporator, which will significantly reduce the efficiency of heat transfer. Atlant refrigerator It will last longer if you maintain a balance between operation and maintenance.
In this article we will look in detail at how often it is necessary to carry out defrosting for various series of equipment, what mistakes users make and how to properly prepare the unit for this procedure. Understanding the physics going on inside the camera will help you avoid common problems. You will learn to determine the optimal time to turn off the power without compromising the safety of food.
Dependence of defrosting frequency on the cooling system
The first thing to do before planning a maintenance schedule is to determine the type of cooling system installed in your model. The Atlant plant produces equipment with both classic drip system (Direct Cool) and technology No Frost. These two types differ fundamentally in the principle of operation of the evaporator and, accordingly, in the requirements for care.
In models with a drip system, moisture from the air condenses on the back wall of the refrigerator compartment, freezes and turns into frost. Periodically, the compressor turns off, the wall heats up, and the ice melts, flowing into the drainage hole. However, the freezer compartment in such models, as a rule, requires manual defrosting. The ice does not disappear there and grows with each cycle of the compressor operation.
If you have a model with the No Frost system, then the evaporator is hidden behind a plastic panel, and air circulation is forced. In such units, moisture is removed automatically, and the formation of a snow coat is minimal. However, even for them there is a recommendation for preventive shutdown, which we will discuss below.
It is important to understand that mixed systems, often called “Full No Frost” or “Total No Frost”, may have different requirements for the refrigerator and freezer compartments. Carefully study the technical data sheet of the device so as not to harm the equipment with unnecessary intervention.
Recommended intervals for models with a drip system
For owners of Atlant refrigerators with manually controlled defrosting of the freezer, the issue of frequency is most acute. The manufacturer recommends completely defrosting the freezer compartment at least once a year. However, this period is minimal and is relevant only under ideal operating conditions.
In reality, the intervals may be shorter. If you often open the door, warm, humid air enters the chamber, which instantly condenses on the cold walls. Also, the rate of ice growth depends on the humidity in the room and the tightness of the seals. If you notice that a layer of frost has become visually noticeable, there is no point in waiting a year.
⚠️ Attention: If the thickness of the ice cover in the freezer has exceeded 5-7 mm, defrosting must be carried out immediately. Operation with a thick “coat” forces the compressor to work without rest, which can lead to its overheating and failure.
The procedure is considered optimal 2 times a year for example, in spring and autumn. This allows you to maintain hygienic cleanliness inside the chambers and ensures maximum energy efficiency. A thin layer of ice acts as a heat insulator, preventing products from cooling to the desired temperature.
There is a myth that modern Atlant models with a drip system do not need to be defrosted at all. This is a misconception. Mechanical removal of ice with a knife or other sharp objects is strictly prohibited, as this can damage the refrigerant pipeline. Only natural defrosting guarantees the safety of the system.
Is it necessary to defrost the Atlant No Frost refrigerator
Many users mistakenly believe that appliances labeled No Frost (“no frost”) do not require defrosting at all. Indeed, in such models, such as the popular series Atlant XM-4425 or XM-6025, the system automatically gets rid of moisture. However, a complete lack of maintenance can lead to unpleasant consequences.
Even in No Frost systems, dust, microparticles of food and bacteria accumulate over time in hard-to-reach places where air flow does not reach. In addition, the drainage system may become clogged. Therefore, manufacturers recommend carrying out preventive defrosting once every 1-2 years.
This procedure is necessary not to remove ice that should not be there, but for:
- 🧼 Thorough sanitary treatment of internal surfaces and removal of odors.
- 💨 Cleaning drainage channels and ventilation holes.
- 🔍 Check the condition of sealing rubber bands and plastic elements.
- 🔌 Give the electronics and compressor a rest after long periods of continuous operation.
If you live in a region with very high humidity or often leave the door open, The frequency of procedures can be increased to once a year. This will help avoid the formation of ice jams in the air channels, which sometimes happens when operating rules are violated.
What will happen if you ignore No Frost defrosting?
In the No Frost system, ice can form inside the housing, around the hidden evaporator. This will cause the fan to start making noise, touching the ice with its blades, and the cold will stop flowing into the chamber. As a result, the products will spoil, and repairs will cost more than regular maintenance.
Signs that defrosting cannot be postponed
Sometimes calendar deadlines fade into the background, and the need for defrosting is signaled by the behavior of the equipment itself. There are a number alarming symptoms, ignoring which can cost you expensive repairs. If you notice at least one of them, plan to turn off the refrigerator in the near future.
First of all, pay attention to the operation of the compressor. If it starts to turn on more often than usual or works almost without interruption, this is a sign that heat exchange is impaired. The ice crust interferes with cooling, temperature sensors record deviations and cause the motor to wear out.
Also signs of the need for urgent defrosting are:
- ❄️ A noticeable decrease in the quality of freezing: the food in the freezer has become softer than usual.
- 💧 Appearance puddles under the refrigerator or inside the chamber, which indicates an overflow of the drainage.
- 🔊 The appearance of extraneous sounds: gurgling, crackling or humming that were not there before.
- 📉 Increase in electricity consumption, which can be tracked by bills or smart sockets.
Another important factor is the appearance of an unpleasant odor that cannot be eliminated by regular washing. This suggests that bacteria have grown in layers of old ice or in the drainage system. In this case, defrosting will be combined with general cleaning and disinfection.
Step-by-step instructions for correct defrosting
For the procedure to be quick and safe for equipment, it is important to follow the correct algorithm of actions. Random switching off and on can damage the compressor. Below is the sequence that is relevant for most Atlant models.
First, empty the chambers of food. Place them in bowls of cold water or wrap them in thick cloth if there is no other cold place nearby. Then unplug the refrigerator. Do not pull out the plug with a jerk, hold on to the plug body.
☑️ Checklist for preparing for defrosting
Leave the refrigerator and freezer doors completely open. This will provide an influx of warm air and speed up the melting of the ice. Place rags or containers under the bottom of the freezer and on the refrigerator shelves to collect water. It is strictly forbidden to use hair dryers, heaters or hot water to speed up the process - a sudden change in temperature can cause cracks in the plastic or deformation of the evaporator.
While the defrosting process is in progress, wash the removable shelves, drawers and inner walls of the chambers with warm water and a mild detergent. Do not use abrasive powders or harsh chemicals. After all the ice has melted, thoroughly wipe all surfaces dry.
You can turn on the refrigerator only after it is completely dry. Assemble the structure, close the doors and leave the unit to operate empty for about 2-3 hours. Only after reaching the set temperature can products be loaded.
| System type | Min. frequency | Opt. frequency | Sign of urgency |
|---|---|---|---|
| Drip (Direct) | once a year | 2 times a year | Ice > 5 mm |
| No Frost | 1 time every 2 years | 1 time a year | Smell / Noise |
| Combined | 1 time a year | 2 times a year | Ice in the freezer |
Typical mistakes during defrosting and their consequences
Even knowing how often the Atlant refrigerator needs to be defrosted, users often make mistakes in the process. The most common of them is try chop off the ice with a knife. This action in 90% of cases leads to a puncture of the evaporator tube. The refrigerant evaporates, and air and moisture enter the system. Repair in this case requires calling a specialist, vacuuming and refilling with freon, which is expensive.
The second mistake is turning on the refrigerator immediately after washing. If moisture remains inside, it may get onto the electrical contacts or into the drain hole, causing a short circuit or ice blockage. Always dry the chamber thoroughly.
⚠️ Warning: Do not leave the refrigerator unattended to defrost for long periods of time, especially if you have pets or small children. Open doors and puddles of water on the floor can become a source of danger.
The third mistake is the use of aggressive cleaning products. Chlorine or strong acids can corrode plastic and rubber seals, making them hard and brittle. This will lead to loss of seal and faster ice buildup in the future. Use only special household appliance products or soda solution.
Sometimes users forget to check the drainage hole after defrosting. If it is clogged, water during the next automatic defrost (in drip models) will flow not into the tray, but into the refrigerator or onto the floor. Clean it with a special brush or soft wire.
Is it possible to defrost a refrigerator in winter on the balcony?
Take it out A working or just defrosted refrigerator cannot be exposed to frost. The oil in the compressor thickens and the plastic becomes brittle. If you do take the case out for ventilation, before turning it on, it should stand in a warm room for at least 4-6 hours to warm up to room temperature.
Why does the refrigerator not get cold for a long time after defrosting?
This is normal. After washing, warm air filled the chamber volume. The compressor takes time to cool the plastic and air. If the temperature does not drop within 3-4 hours, check whether the door is tightly closed and whether the “Super Freeze” mode (if any) is turned on, which sometimes blocks the normal cycle.
Do you need to lubricate the seals after defrosting?
Yes, this is an excellent preventive measure. The rubber seal may dry out after contact with water and detergents. Wipe it with special silicone grease or glycerin. This will maintain the elasticity of the rubber and ensure a tight fit of the door, which is critical to prevent ice formation.
What to do if the water does not leave the drain?
Take a soft rubber bulb or syringe without a needle, draw warm water and try to gently push the blockage in the drain tube. If there is water in the tray under the compressor, it needs to be removed and washed. Stagnant water is an ideal environment for mold.
