Owners of household appliances often wonder how often and correctly the defrosting procedure should be carried out in order to extend the life of the unit. Refrigerators Pozis have proven themselves to be reliable devices that can operate for years with proper care. However, even the most modern models require periodic maintenance, which includes removing ice crust and frost from the internal surfaces.
Incorrect defrosting can lead to failure of the compressor or damage to the plastic elements of the housing. It is important to understand that the approach to maintenance depends on the type of cooling system installed. In this article, we will analyze in detail the algorithm of actions for various models, point out typical errors and help avoid common problems.
⚠️ Attention: before starting any maintenance work, be sure to disconnect the refrigerator from the electrical network to avoid electric shock.
Determining the type of cooling system
The first step before starting maintenance is to accurately determine the type of cooling system of your device. Models Pozis can be equipped with classic drip system (Direct Cool) or more modern technology No Frost. The frequency of the procedure and its complexity directly depend on this.
If you are not sure which system is installed in your unit, pay attention to the back wall of the refrigerator compartment. If there is a visible evaporator hidden behind the panel, or there has been no ice for a long time, most likely you have a model with automatic defrosting. The drip system requires manual intervention when the ice layer reaches 5-7 mm.
- ❄️ Drip system: requires manual defrosting 1-2 times a year.
- 🌬️ No Frost: defrosting is only needed in case of breakdown or general cleaning once every 2-3 years.
- 🔧 Combined: the refrigerator compartment defrosts itself, the freezer defrosts manually.
Ignoring the type of system can lead to unnecessary actions. For example, owners often try to defrost the system No Frost as planned, which is not required by the manufacturer. In such systems, moisture is removed automatically through the drainage hole.
Preparation for defrosting refrigerator
High-quality preparation takes more time than the process of thawing the ice itself. Make room for storing food in advance, as you will have to remove it completely. If it's winter outside, you can take the food out to the balcony, but make sure that the temperature is not extremely low for some types of food.
It is necessary to prepare absorbent materials. Water draining from the evaporator can damage the flooring. Lay old towels, rags around the refrigerator in advance, or use special absorbent diapers. You will also need containers for collecting water if the model does not have a built-in tray with a high side.
☑️ Preparation checklist
It is important to remove all removable shelves, drawers and containers in advance. Plastic becomes brittle in the cold, and sudden temperature changes during washing can lead to cracks. Allow the shelves to warm up to room temperature before contacting water.
Step-by-step instructions for defrosting
The process of defrosting refrigerators Position with a drip system is quite simple, but requires patience. The main rule is not to rush the process by mechanically removing ice. Follow the algorithm to avoid damaging the evaporator tubes.
First, unplug the device and open the doors. Leave them in this position for several hours. Natural thawing is the safest method. If there is a lot of ice, the process may take from 4 to 10 hours depending on the room temperature.
As the ice melts, regularly wipe the interior surfaces and remove water. When the ice is completely gone, you need to thoroughly wash the camera. Use a warm baking soda solution or mild detergent. Rinse all surfaces thoroughly with clean water.
⚠️ Warning: Never use a knife, icebreaker or other sharp object to chip ice. One awkward movement can break through the cooling circuit, and repairs will become economically unfeasible.
What to do if the ice does not melt?
If 5 hours have already passed and the ice crust remains, you can speed up the process. Place a pan of hot (but not boiling) water on a wooden board inside the chamber. Close the door. Heat will speed up the melting. Do not place hot dishes on a plastic floor!
Use of accelerating methods
Sometimes a situation arises when there is no time to wait for natural thawing. In such cases, auxiliary means can be used, but this must be done with extreme caution. The main method is to use heat.
You can use a hair dryer, directing a stream of warm air onto the ice crust. Keep the device at least 30 cm away from the plastic and constantly move it to avoid overheating certain areas. Overheating can deform the internal plastic of the camera.
Another method is to use a spray bottle with warm water. Spray ice build-ups to help them melt faster. However, make sure that water does not get on electrical contacts or technical openings.
- 🔥 Hair dryer: effective, but there is a risk of overheating the plastic.
- 💦 Warm water: safe, but requires frequent wiping.
- 🧊 Salt: sprinkling salt on the ice speeds up the melting, but requires thorough rinsing after.
Features of defrosting the freezer compartment
Freezers, especially in models without No Frost, become overgrown with ice faster than the refrigerator compartment. A thick layer of snow reduces the efficiency of the compressor and increases energy consumption. Thermal insulation It gets worse, and the food may not be cold enough.
When defrosting the freezer, it is important to check the condition of the sealing gum. It is the loose fit of the door that is often the reason for the rapid growth of fur coats. Wipe the rubber with a weak solution of vinegar or a special rubber care product.
| Parameter | Refrigerator compartment | Freezer compartment |
|---|---|---|
| Frequency | 1-2 times per year | As ice forms |
| Duration | 3-6 hours | 6-12 hours |
| Temperature | +4...+6 °C | -18...-24 °C |
| Risk for products | Minimum | High (needs cold) |
After defrosting the freezer, be sure to wipe it dry before turning it on. Residual moisture will instantly turn into ice when the compressor starts, which will again create an unwanted crust.
Care after defrosting and start-up
After you have washed and wiped all surfaces dry, do not rush to load food right away. Let the refrigerator run idle for at least 2-3 hours. This will stabilize the temperature and ensure that the thermostat is working correctly.
Pay attention to the drainage hole. It often becomes clogged with crumbs or mucus. Clean it with a special brush or soft wire so that condensation can drain freely. Clogged drainage is a common cause of puddles under vegetable drawers.
Regular maintenance of the refrigerator Position includes not only defrosting, but also checking for cleanliness capacitor at the back. Vacuum the radiator grille every six months to ensure good heat transfer.
Typical maintenance mistakes
Many users make mistakes that shorten the service life of equipment. The most common is turning on a wet refrigerator. Water that gets into electrical circuits or contacts can cause a short circuit.
Another mistake is the use of aggressive chemicals. Abrasive powders, chlorine-containing products and solvents can damage the inner lining of the chambers and the plastic. Use only soft sponges and neutral detergents.
⚠️ Attention: characteristics and maintenance requirements may vary slightly depending on the specific series. Always check the official instructions for your model.
Do not forget that proper operation is the key to long-term operation. If you notice that the refrigerator has become louder, freezes worse, or forms ice faster than usual, this may indicate a malfunction that defrosting will not fix.
Frequently asked questions (FAQ)
How often do you need to defrost a Pozis refrigerator with No Frost?
Models with system No Frost do not require scheduled defrosting to remove ice. However, once every 1-2 years it is recommended to carry out general cleaning with disconnection from the network for hygiene and maintenance of ventilation ducts.
Is it possible to defrost a refrigerator with a hair dryer?
Yes, you can, but with caution. Use the warm air mode, keep the hairdryer at a distance and do not direct the jet for a long time at one point, so as not to deform the plastic.
What to do if the refrigerator does not turn on after defrosting?
Check the network connection and the presence of voltage in the outlet. If everything is fine electrically, the thermal protection relay may have tripped. Wait 30-60 minutes and try to turn it on again. If the problem persists, you need a technician.
Do you need to wash the inside of the refrigerator after defrosting?
Yes, definitely. As the ice melts, plaque, bacteria and possible contaminants remain on the walls. Wipe the chambers with a solution of soda or a mild detergent and wipe dry.
