Modern household appliances greatly simplify life, but even advanced technologies require periodic maintenance. Refrigerators Biryusa with the system No Frost (or Low Frost) are positioned as devices that do not require defrosting, but this is not entirely true. Periodically, at least once a year, the unit needs manual defrosting to clean it from odors, dust and bacteria that are not removed automatically.
Many owners mistakenly believe that the absence of ice on the walls of the chamber means a complete lack of need for maintenance. In fact, condensation and dirt accumulate over time in the drainage system and evaporator hidden behind plastic panels. If you ignore this process, performance the compressor may fall, and an unpleasant odor will appear inside.
In this article we will analyze in detail how to correctly carry out the defrosting procedure for models Biryusain order not to damage the equipment and extend its service life. You will learn about the nuances of turning off the power, ways to speed up the process and actions that are strictly prohibited when working with refrigeration equipment.
Why the No Frost system needs defrosting
System No Frost (literally “without frost”) works due to forced air circulation. The fan drives air masses through the evaporator, where they are cooled, and then distributes the cold throughout the chambers. It would seem that frost simply has nowhere to come from, since moisture must be frozen out on the evaporator and removed through the drainage system.
However, over time, blockages may form in the drainage channels due to microparticles of food or mold. Moisture stops flowing into the pan and begins to accumulate inside the housing. This leads to the formation of an ice coat in places inaccessible to visual inspection, which creates additional load on the compressor compressor.
In addition, bacteria multiply in any refrigerator, regardless of the type of cooling. Regular defrosting and washing allow you to:
- ☄️ Remove persistent unpleasant odors that are absorbed into rubber seals.
- ☄️ Clean hard-to-reach corners and ventilation holes from dust.
- ☄️ Check the condition rubber seals on the doors.
⚠️ Attention: If you notice that the refrigerator has started to work louder than usual or drops of water have appeared on the back wall, this is a signal that it is time to defrost and clean the system, even if there is no visible ice.
Ignoring these factors can lead to the fact that Biryusa it will start to freeze worse or completely fail. Preventive defrosting does not take much time, but saves you from expensive repairs.
Preparation for the defrosting process
Before starting any work with electrical appliances, it is necessary to ensure safety. First of all, empty the cameras of food. If it’s winter outside, you can take perishable food items out to the balcony after pre-packing them. In the warm season, use thermal bags or fill pots with water and put food there, placing them in a cool place.
Next, you need to disconnect the device from the power supply. Simply remove the plug from the socket. Do not pull the wire to avoid damaging the contacts. If the outlet is located in a hard-to-reach place, use an extension cord or contact an electrician to install the outlet in a convenient area.
Prepare equipment for collecting water. In models Turk water can flow not only into a special pan, but also flow out if the drainage hole is clogged. You will need:
- 🧽 Several large terry towels or rags.
- 🪣 A wide basin or several containers for water.
- 🧼 A soft sponge and detergent for refrigerators.
☑️ Preparation for defrosting
It is also important to remove all removable elements: shelves, drawers, egg trays. It is better to wash them separately under running water. Plastic does not like sudden temperature changes, so do not place cold shelves directly under hot water - they may crack. Let them warm up to room temperature.
Step-by-step instructions for defrosting
The safest and most correct way to defrost a refrigerator Biryusa is natural defrosting. After you have turned off the appliance and removed the food, leave the chamber doors open. Air circulation will start the process of ice melting.
The time for complete defrosting can vary from 8 to 24 hours, depending on the temperature in the room and the amount of ice. Do not try to speed up the process with mechanical force; we will talk about this in the section on prohibited actions. During this time, periodically wipe the internal surfaces with a dry cloth, collecting drainage water.
Pay special attention to the drainage hole. It is usually located on the back wall of the refrigerator compartment. If water sits in the groove and does not drain, carefully clean the hole with a special brush or soft wire wrapped in a cloth. You can use a syringe with warm water to push through the clog.
How long does defrosting take?
On average, it takes about 10-12 hours for the ice in the No Frost system to completely thaw. Do not turn on the refrigerator until the interior surface and drainage system are completely dry.
After all the ice has melted, thoroughly wipe all surfaces dry. A humid environment is an ideal place for mold to grow immediately after turning on the appliance. Make sure that there are no puddles left in the corners and under the shelves.
What you ABSOLUTELY NOT DO
There are a number of common misconceptions about how to quickly defrost a refrigerator, which can lead to fatal consequences for equipment Turk. The most important rule: never use sharp objects to chip ice.
An attempt to pick out ice with a knife, screwdriver or butter knife is almost guaranteed to lead to a breakdown. evaporator. Refrigerant (freon) circulates in the tubes, and if the tube is damaged, it will instantly evaporate with a whistle. Repair in this case will be difficult and expensive, often requiring replacement of the entire circuit.
It is also prohibited to use to speed up the process:
- 🔥 Hair dryers (heat gun) - hot air can deform the plastic case and damage the wiring.
- 🔥 Hot water bottles placed directly on the shelves - a sharp temperature change destroys the structure of the plastic.
- 🔥 Candles or other sources of open fire are a fire hazard and can melt internal elements.
⚠️ Attention: Damage to the evaporator by sharp objects or overheating the plastic with a hairdryer is not a warranty case. Repairs at your expense will cost 60-70% of the cost of a new refrigerator.
Another mistake is turning on the appliance ahead of time. If you start the compressor while there is still water or high humidity inside, this may cause an electrical short circuit or water hammer in the cooling system.
Washing and disinfection after defrosting
Defrosting is the ideal time for general cleaning. After removing ice and water, thoroughly wash the interior surfaces. To do this, it is best to use specialized refrigerator cleaning products or a weak soda solution (1 tablespoon per liter of water).
Do not use abrasive powders, hard brushes or aggressive chemicals (chlorine, acids). They can scratch or change the color of the plastic and leave an odor that transfers to the food. Pay special attention to the rubber seals on the doors: dirt and mold often accumulate in their folds.
To wash the rubber bands, use a soft cloth soaked in a soapy solution. If there are black spots of mold on the rubber, they can be carefully removed with a cotton swab dipped in hydrogen peroxide. After washing, be sure to wipe all surfaces clean with a damp and then dry cloth.
| Element | What to wash | What to dry | Features |
|---|---|---|---|
| Internal walls | Soda solution or special. product | Microfiber | Avoid getting water into the holes |
| Seals | Soap solution | Dry soft cloth | Do not stretch the rubber |
| Shelves (glass) | Warm water + detergent | Paper towel | Allow to warm up before washing |
| Boxes (plastic) | Warm water | Rags | Do not use boiling water |
After finishing cleaning, leave the refrigerator open for another 15-20 minutes so that the smell of the detergent disappears and excess moisture is removed. Only after this can you install the shelves and drawers in place.
Completion of the process and first start-up
When the refrigerator Biryusa is completely dry and clean, and all removable elements are in place, you can start turning it on. Insert the plug into the outlet. Don't download products right away! An empty refrigerator needs time to reach operating temperature.
Usually this process takes from 2 to 4 hours. In modern electronically controlled models, an alarm indicator may light up on the display or the temperature may flash to indicate that the cooling process is in progress. This is normal.
It is better to load products in small portions. First, put in shelf-stable products that do not require extremely low temperatures, and after an hour or two you can fill the chambers completely. A sudden load with a large volume of warm products can cause the compressor to wear out.
Frequently asked questions and problems (FAQ)
Is it possible defrost the Biryusa refrigerator with a hairdryer?
Using a hairdryer is highly not recommended. The hot air flow can locally overheat the plastic, causing it to deform, or damage wiring and temperature sensors located close to the walls. Natural defrosting is safer.
How long should the refrigerator stand after defrosting before turning it on?
A special “settling” time is not required for modern refrigerators if you have not carried out repairs by changing the oil or freon. The main condition is that the inner surface must be absolutely dry. You can turn it on immediately after cleaning.
What to do if after defrosting the refrigerator does not freeze?
If after turning it on for 4-5 hours the temperature does not drop, check whether the doors close tightly. If everything is in order with the doors, the evaporator may have been damaged during defrosting (freon leaked) or the start relay has failed. In this case, you need a master.
Do you need to lubricate the seals after washing?
Yes, this will extend their life. You can use special silicone grease for refrigerators or regular glycerin. This will prevent the rubber from drying out and improve the fit of the door.
Following these simple rules will allow your refrigerator Biryusa serve for many years without breakdowns. Regular care takes a minimum of time, but guarantees the safety of food and the absence of unpleasant surprises in the form of leaks or defrosted meat.
