Owners household appliances Pozis people often wonder how often and how it is necessary to carry out the de-icing procedure in order for the unit to serve for many years. The correct approach to maintenance can maintain the energy efficiency of the compressor and prevent the appearance of foreign odors. The two-chamber models of this brand, despite their reliability, require regular attention to the hygienic condition of the freezer.
Modern refrigerators can be equipped with a system No Frostthat minimizes the formation of ice, or a classic drip system that requires manual intervention. Understanding the differences between these types is critical, as incorrect operation can damage the evaporator or compromise the seals. Below we will analyze in detail the algorithm of actions for safe and effective defrosting.
The process of restoring the functionality of the unit takes different times depending on the thickness of the snow coat and the temperature in the room. Pozis refrigerator is a technique that, with proper care, retains its performance characteristics for decades. It is important to take your time and follow all the steps to avoid stress for the compressor.
Determining the type of cooling system and frequency of procedures
The first step before starting any manipulations is to find out the type of cooling system installed. In two-chamber models Pozis there is often a combination: a drip system in the refrigerator compartment and No Frost in the freezer. This means that the upper part defrosts automatically, and the lower part requires manual cleaning of food and periodic airing.
If your unit is equipped with the good old static system, then ice will accumulate on the back wall of the freezer. The frequency of such procedures directly depends on the humidity in the room and the tightness of the door. Typically, the interval is from once every 4 months to once every six months.
⚠️ Attention: If you notice that ice is growing faster than usual (for example, in a month), this is a signal of a malfunction. Check the tightness of the rubber seals or the operation of the thermostat.
Ignoring the need for defrosting leads to an increase in energy consumption, since a layer of ice 5 mm thick reduces the heat transfer of the evaporator by 10-15%. The compressor is forced to work almost without interruption, which reduces its service life. In mechanically controlled models, sensors may incorrectly read the temperature through the snow insulation layer.
Preparatory stage: safety and preservation of products
The process must begin by preparing the workspace and ensuring the safety of electrical appliances. Before turning off refrigerator from the mainsmake sure your hands are dry and the floor in the access area is not flooded with water. This is a basic rule of electrical safety that cannot be ignored.
Next you should deal with the contents of the cameras. All perishable foods must be removed. If you plan to quickly defrost in winter, you can take the food out to the balcony after pre-packing it. In the warm season, you will have to use thermal bags or leave them in your neighbors' working refrigerator.
- 🧊 Prepare several terry towels and basins to collect melt water.
- 🔌 Find and free access to an electrical outlet in advance.
- 🧼 Prepare mild detergent for subsequent cleaning.
- 🚪 Open the doors wide to ensure the flow of warm air.
It is also important to free up space around the unit. Move Pozis away from the wall if possible to allow access to the rear and prevent water from getting on wallpaper or flooring. In some models, access to the drain hole may be difficult if the equipment is standing closely.
Step-by-step instructions for defrosting the Pozis refrigerator
After the equipment is disconnected from the power supply and the food has been removed, the main stage begins. Do not use a hairdryer or other heating devices to speed up the melting of ice - a sudden temperature change can damage the plastic and evaporator tubes. The natural process, although longer, is safer for refrigerant and the design.
Place towels on the floor in front of the freezer door. If your model has a drainage channel, make sure it is not clogged with food crumbs. During the thawing process, periodically check the fullness of the water containers to avoid overfilling.
☑️ Checklist for proper defrosting
While the ice is melting, you can start washing the shelves and drawers. They should be removed from the chamber and washed with warm water and a mild detergent. The use of abrasive powders or hard brushes is strictly prohibited. Pay special attention to the inner walls of the chamber. Wipe them with a soft sponge soaked in a weak solution of soda or vinegar. This will help eliminate unpleasant odors and disinfect the surface. After treatment, be sure to wipe all surfaces with a dry cloth. strictly prohibited, since they leave micro-scratches on the plastic, in which bacteria will subsequently multiply.

Features of caring for the No Frost system
Owners of two-chamber models Pozis with technology No Frost often mistakenly believe that they do not need defrosting at all. Although manually chipping ice in the freezer is not required, hygienic cleaning and maintenance are necessary. The system works by circulating cold air, and the ventilation channels can become clogged with dust or food particles.
Once a year, it is recommended to completely defrost even such units. This is necessary in order to check the drainage system that removes condensate. If the drainage hole becomes clogged, moisture will begin to accumulate inside the housing or flow out, damaging the floor.
| System type | Defrost frequency | Necessity of chipping ice | Drainage care |
|---|---|---|---|
| Static (Drip) | 1-2 times a year | Required | Regular check |
| No Frost | 1 time a year (hygiene) | Not required | Cleaning required |
| Low Frost | once a year | Minimum | Check as necessary |
When cleaning ventilation ducts in models No Frost use a soft brush or cotton swab. Do not try to pierce the ducts with sharp objects, as this may damage the sensors or fan blades. Accuracy is the key to long-term operation of the system.
Completion of the process and first launch
When all the ice has melted, and the internal surfaces have been washed and, most importantly, thoroughly wiped dry, you can begin assembly. Make sure there are no puddles in the corners of the chamber or under the drawers. Moisture inside the sealed space will quickly cause new ice to form and mold to grow.
Put the shelves and drawers back into place. Keep the doors open for another 10-15 minutes to allow any remaining moisture to completely evaporate. Only after this can you connect the refrigerator to the power supply.
⚠️ Attention: Do not load food immediately after turning it on! Let the equipment run idle for 2-3 hours so that it reaches operating temperature and the compressor turns off automatically.
The first start is stressful for the compressor. If you have just transported the unit or defrosted it, the oil in the compressor may have moved. Let it settle and return to the crankcase before running the coolant cycle. This is especially important for models with a bottom-mounted compressor.
What to do if a smell appears after defrosting?
If an unpleasant odor appears after defrosting, wipe the inner walls with a solution of citric acid (1 teaspoon per liter of water) or use activated carbon, leaving it in the chamber for a day. Do not use aggressive chemicals.
Typical defrosting mistakes and their consequences
The most common mistake is using a knife or sharp objects to chip ice. In models Pozis, as in other refrigerators, the evaporator is often located close to the wall. One wrong move can puncture the tube, causing a freon leak. Repair in this case will be expensive and difficult.
The second mistake is turning on the unit immediately after the ice has melted, but the walls are still wet. This leads to the formation of an ice crust after just a few hours of operation. Moisture must be removed mechanically (with a rag); evaporation during operation of the refrigerator will not help here.
- 🚫 Do not pour hot water on the ice to speed up the process - the plastic may be deformed.
- 🚫 Do not leave the doors open for a long time unattended - the hinges may sag.
- 🚫 Do not use chemical solvents to remove fat from plastic.
Also, do not ignore the condition of the sealing gum. During defrosting, it must be carefully washed and lubricated with silicone grease (special for refrigerators) so that it does not dry out and ensures a tight seal. Loss of elasticity of the seal is a common cause of freezing of the “fur coat”.
FAQ: Frequently asked questions
Is it possible to defrost the Pozis refrigerator without unplugging it?
It is absolutely not possible. Defrosting means completely disconnecting from the power supply. Running the compressor while the ice is melting will cause it to overload and possibly fail, and will also create a risk of electric shock due to moisture.
How long does it take to defrost a two-chamber refrigerator?
The time depends on the thickness of the ice and the temperature in the room. Typically the process takes from 3 to 6 hours. Do not try to artificially speed it up with heating devices, so as not to damage the plastic and the cooling system.
Is it necessary to defrost a refrigerator with a No Frost system?
They do not need complete defrosting with chipping of ice, since they do it automatically. However, once a year it is recommended to carry out a hygienic wash and check the drainage system, unplugging the appliance for several hours.
What to do if the refrigerator does not freeze after defrosting?
Check whether the doors are tightly closed and whether the refrigerator is not loaded with food immediately. If the temperature does not drop within 4-5 hours, the circuit may have been damaged during cleaning or a power surge may have occurred. A call from a specialist is required.
