Regular maintenance of household appliances is the key to their long service, and brand refrigerators Pozis are no exception. Despite the fact that many modern models are equipped with No Frost systems, a significant part of the operating fleet in Russia operates using a drip system or requires manual defrosting of the freezer compartment. Ignoring this procedure can lead to a decrease in cooling efficiency, increased energy consumption and even compressor failure due to overload.
Owners often wonder how often this procedure needs to be carried out and whether it is possible to speed up the process without harming the internal shelves. Proper defrosting - this is not just waiting for the ice to melt, but a set of actions to clean the drainage holes and check seals. It is important to understand that haste in this matter often leads to damage to the evaporator, which entails expensive repairs.
In this article we will analyze in detail the algorithm of actions for various models, point out typical errors and provide a checklist for safe work. You will learn why you should not use a hair dryer or knife to chip ice, and how to properly prepare the equipment for restart. Following these simple rules will allow your Pozis refrigerator work silently and efficiently for many years.
Design features and types of Pozis defrosting
Before taking active steps, it is necessary to accurately determine the type of defrosting system installed in the your model. The equipment Pozis can be equipped with both a classic drip system and more modern technology No Frost. In the first case, moisture flows down the back wall of the refrigerator into a special gutter, and the freezer requires manual defrosting.
If you have a model with the No Frost system, then theoretically it does not require frequent human intervention, since air circulation prevents the formation of ice. However, even in such units it is recommended to carry out preventive defrosting once a year for hygienic treatment and checking the operation of the fans. For models with manual defrosting, this process is a prerequisite for operation.
You can determine the type of your model by the markings or user manual. Often on the front panel or inside the chamber there are indications of the number of stars indicating the minimum temperature and the need for maintenance. It is critical to know that models with one compressor and the Full No Frost system are less common and require a special approach to shutdown.
⚠️ Attention: Do not try to determine the type of defrosting only by the presence of ice. Even in No Frost systems, if the damper or thermostat malfunctions, an ice crust may form, requiring elimination of the cause, and not just melting.
Preparatory stage before shutting down
You need to start the process long before you pull the cord from the outlet. The first step will be complete unloading the refrigerator. All products, especially perishable ones, must be removed. If you plan to store them during defrosting, prepare thermal bags, ice packs, or ask your neighbors to temporarily accept some of the supplies.
Next, you should adjust the temperature. Before completely shutting down, it is recommended to turn the temperature regulator to the “0” or “Off” position, if such an option is available, and let the equipment operate in this mode for 10-15 minutes. This will stabilize the pressure in the refrigerant system before stopping the compressor.
Don't forget to prepare a place to drain the water. Place well-absorbing rags, towels on the floor in front of the refrigerator in advance, or use special moisture-proof mats. When a large amount of ice melts, water may flow out of the chamber if the drainage hole is clogged.
☑️ Preparing for defrosting
Check access to the drainage hole. In some models Pozis it may be hidden by a plastic panel. If you plan to clean it, prepare a soft rubber bulb or syringe without a needle for rinsing.
Step-by-step instructions for defrosting
The safest method recommended by manufacturers is natural thawing. After you have unplugged the appliance, leave the freezer and refrigerator doors wide open. The process of ice melting, depending on the thickness of the ice and the temperature in the room, can take from 4 to 10 hours.
During the melting process, water will flow into the drip receiver located above the compressor at the back, or directly to the floor if the container overflows. Check the drain pan regularly and empty the water to avoid kitchen flooding. Do not leave the process unattended for a long time if you are not sure of the tightness of the drainage system.
If time is running out, you can use the accelerated defrosting method with caution. It is allowed to install containers with hot (but not boiling water!) water in the chamber. This will create a steam bath that will speed up the melting. You need to change the water every 15-20 minutes.
Is it possible to use a hair dryer?
Using a hair dryer is permissible only in extreme cases and maintaining a distance of at least 30 cm from plastic parts. Hot air can deform the internal plastic or damage the seals, so this method is not recommended by service center engineers.
During defrosting, it’s time to check the condition sealing rubber bands. Wipe them with a soft cloth dampened in a mild soap solution. If the rubber has lost its elasticity or has cracks, consider replacing it, as this directly affects the frequency of ice formation in the future.
What absolutely should not be done
There are a number of actions that can instantly put your Pozis out of action. The most common mistake is using sharp objects to chip ice. A knife, screwdriver or ice pick can easily pierce the thin wall of the evaporator where the refrigerant circulates.
If the circuit depressurizes, the freon will evaporate, and moisture and air will get inside the system. Repair in this case will be complex, expensive and not always economically feasible. Restoring the evaporator requires evacuation of the system and filling with gas, which only specialists can do.
It is also prohibited to use open fire or powerful heating devices in close proximity to the plastic. The internal shelves and walls of the chamber are made of materials that, with a sharp change in temperature, can crack or change their geometry.
- 🚫 Do not use a knife, hatchet or other sharp objects to remove ice.
- 🚫 Do not pour boiling water directly onto the shelves and walls of the chamber.
- 🚫 Do not turn on the refrigerator until you are sure that all moisture has completely dried.
- 🚫 Do not use aggressive chemicals to clean internal surfaces.
⚠️ Attention: Damage to the evaporator by sharp objects is not covered by warranty. The manufacturer will refuse free repairs if it finds traces of mechanical intervention.
Cleaning and care after defrosting
After all the ice has melted and the water has been removed, it is necessary to thoroughly rinse the interior. Use warm water with baking soda or a special refrigerator cleaner. This will help eliminate unpleasant odors and bacteria that could multiply in the ice.
Pay special attention to the drainage hole. If it is clogged, water will accumulate at the bottom of the chamber and freeze, forming an ice plug. You can clean the channel using a soft wire wrapped in cotton wool or a special brush. After cleaning, pour in a little warm water to check the permeability.
After wet cleaning, be sure to wipe all surfaces dry with a clean rag. Moisture should not remain anywhere, especially in corners and around seals. Let the chamber dry completely, leaving the doors open for another 30-60 minutes.
Correctly starting the refrigerator
Starting the refrigerator Pozis After defrosting it must proceed according to a certain algorithm. First, make sure that all parts (shelves, drawers, trays) are completely dry. Then turn on the appliance, but do not load any food yet.
Let the refrigerator run idle for at least 2-3 hours (and preferably 5-6 hours for models with a larger volume). During this time, the compressor will reach the required temperature, and the automation will stabilize. Loading warm products immediately after turning on will cause the motor to wear out.
| Stage | Action | Waiting time |
|---|---|---|
| 1 | Shutdown and defrosting | 4-10 hours |
| 2 | Washing and drying | 1 hour |
| 3 | Idle operation | 2-5 hours |
| 4 | Loading products | After setting the temperature |
If after turning on you hear unusual sounds or notice that the refrigerator is not freezing, check whether the doors are tightly closed. Sometimes skewed shelves after washing can interfere with airtight closure.
Frequency of defrosting and prevention
How often do you need to defrost Pozis? For models with manual defrosting, an interval of 3-4 months is considered optimal, or when the thickness of the ice on the walls reaches 5-7 millimeters. More frequent defrosting does not make sense, and infrequent defrosting leads to a decrease in efficiency.
There are factors that accelerate the formation of ice. These include frequently opening the door, placing hot food inside, damage to the seal, or high humidity in the room. By eliminating these reasons, you can increase the intervals between services.
Monitor the condition of the rubber seals. If they do not fit tightly, warm, moist air constantly enters the chamber, which instantly condenses and freezes. The check can be carried out using a sheet of paper: hold it with the door and try to pull it out - it should come out with force along the entire perimeter.
Possible problems after defrosting
Sometimes after turning on the refrigerator may behave strangely. For example, do not raise the temperature for a long time or make gurgling sounds. Gurgling is normal, as the refrigerant is redistributed throughout the system after inactivity.
If the temperature does not drop after 5-6 hours, check whether the thermostat has moved during cleaning. It is also worth inspecting the rear grille of the condenser: if it is clogged with dust, heat transfer is impaired, and the refrigerator cannot effectively cool the chambers.
- ❄️ Long compressor operation: normal in the first hours after switching on.
- ❄️ Puddle under the refrigerator: the drain hose at the back may have moved.
- ❄️ Curvated shelves: the plastic could be deformed from hot water.
What to do if the refrigerator does not turn on after defrosting?
Check the integrity of the power cord and the presence of voltage in socket. If everything is fine electrically, the compressor thermal relay may have tripped due to an attempt to quickly restart. Let the equipment stand unplugged for another 1-2 hours. If the problem persists, you need to call a technician.
Is it possible to defrost a refrigerator on the balcony in winter?
It is strictly not recommended. The oil in the compressor thickens at low temperatures and the plastic becomes brittle. A sharp temperature change when brought into a warm room can lead to the formation of condensation inside the electronic units and damage to the case.
How to quickly remove the smell of fish after defrosting?
In addition to washing with soda, use a vinegar solution (1 tablespoon per liter of water) for wiping. Once dry, place a bowl of ground coffee or activated carbon inside. Do not use strong fragrances; they can be absorbed into the food.
Do you need to lubricate the door hinges after defrosting?
Yes, that's a great idea. After washing and drying, you can drop a couple of drops of silicone oil or special lubricant onto the hinges. This will ensure silent opening and prevent corrosion of metal elements.
