Modern models of refrigeration equipment, including popular lines Biryusa, are often equipped with automatic moisture removal systems, but even such units require periodic complete defrosting. Many owners mistakenly believe that the presence of a mode No Frost completely eliminates the need for manual intervention in the operation of equipment. In fact, hygienic cleaning and complete shutdown are necessary to maintain sanitary standards and extend the life of the compressor.
Two-chamber models, where the freezer compartment is located at the bottom or top, have their own design features that affect the defrosting procedure. Ignoring regular maintenance can lead to unpleasant odors, decreased energy efficiency, and even evaporator failure. In this article, we will analyze in detail how to carry out the process without stress for the equipment and with maximum benefit for your kitchen.
The first thing that needs to be done before starting any manipulations is to assess the current state of the unit and plan the time. If you notice that an ice crust more than 5 millimeters thick has formed on the walls, or you hear an uncharacteristic hum, you cannot postpone the procedure. Proper preparation It takes longer than the process of thawing the ice itself, so you should not start work in a hurry before the guests arrive.
Design features and types defrosting Biryusa
Refrigerators Biryusa are produced with different cooling systems, and understanding the difference between them is critical for choosing a maintenance method. The drip system, often found in the main compartment, involves periodically defrosting the evaporator during compressor idle cycles. Water flows down the groove into the drainage hole, but in the freezer compartment of such models, ice can accumulate for years if manual defrosting is not carried out.
Models with a system No Frost (or “Windy frost”) circulate dry cold air, preventing the formation frost on products and walls. However, this does not mean a complete absence of condensation. In such devices, moisture is removed through drainage, which over time can become clogged with dust and food particles. That is why even “smart” refrigerators require a complete shutdown at least once a year for deep cleaning of hidden cavities.
Owners of two-chamber units should remember that there are two independent or dependent cooling circuits. If you have a model with one compressor, defrosting occurs simultaneously in both compartments. In more expensive versions with two compressors, you can theoretically turn off the chambers individually, but for complete sanitization it is better to turn off the power to the entire device.
⚠️ Attention: Do not try to speed up the defrosting process by using a hairdryer or hot water in large volumes. A sharp temperature change can cause microcracks in the plastic casing and damage the evaporator tubes, which will lead to freon leakage.
In addition, the design of doors and seals Turks requires careful handling. During defrosting, the doors remain open for a long time, which allows the hinges to move slightly under their own weight if heavy shelves are hung on them. It is recommended to remove all removable elements in advance to reduce the load on the fittings.
Preparation for the procedure: step-by-step algorithm
The beginning of the process is the most critical stage, on which the speed of further actions depends. First you need to empty the chambers of food. If it's winter outside, you can take the food out onto the balcony, but make sure that it doesn't freeze too much or become prey for birds. In the warm season, you will have to use all available containers, ice packs and thermal boxes.
Next, turn off the power supply. Unplug the cord from the outlet, but do not pull on the cable itself to avoid damaging the contacts. If the refrigerator is built into a kitchen unit, provide access to the rear wall to check the condition of the condenser while it is cooling. At this time, you can prepare equipment for collecting water.
- 🧊 Prepare several deep basins and a lot of absorbent rags or old towels.
- 🧽 Dilute a weak solution of soda or vinegar in advance for subsequent washing of the internal surfaces.
- 🛒 Clear the space around the refrigerator so that nothing made it difficult to open the doors wide.
- 📦 Find boxes or cooler bags for temporary storage of perishable foods.
It is also important to remove all shelves, drawers and containers. Plastic parts Turk are quite durable, but at low temperatures they become brittle. Let them sit at room temperature for 15 to 20 minutes before washing to avoid cracking from heat shock. Metal grates can be immediately sent under the tap.
☑️ Preparation checklist
Don't forget to check if there is a drainage hole in the bottom drawer for vegetables. It must be cleaned before the ice begins to melt so that the water flows freely and does not stagnate inside the housing. For cleaning, you can use a soft brush or a cotton swab dipped in warm water.
Defrosting process: natural and accelerated thawing
The safest method recommended by manufacturers is natural defrosting. Just leave the refrigerator doors open and wait. Depending on the thickness of the ice and the room temperature, this process can take from 4 to 24 hours. The advantage of the method is that it completely eliminates the risk of damage to internal components.
If time is running out, you can use gentle acceleration methods. For example, place bowls of hot (not boiling water!) water inside the chambers. The steam will help soften the ice crust. You can also use a fan to direct a stream of air at room temperature into the chamber. This will significantly increase the rate of heat transfer.
It is strictly forbidden to pick the ice with a knife, screwdriver or other sharp objects. The internal walls of refrigerators Biryusa are often made of thin plastic, behind which there are tubes with refrigerant. One careless movement can break through the wall, and repairs will cost 70% of the cost of a new device.
| Defrosting method | Execution time | Risk of damage | Recommendation |
|---|---|---|---|
| Natural (just open) | 6–24 hours | Absent | Recommended by the manufacturer |
| Bowls with warm water | 2–4 hours | Minimum | Safe if careful |
| Hair dryer (warm air) | 1–2 hours | Medium (plastic overheating) | Only at a distance of >30 cm |
| Sharp objects | 10–30 minutes | Critical | Prohibited! |
During the melting process, watch where the water flows. If the drainage hole cannot cope with the volume, replace the container in time and wipe away the puddles. Water should not flow under the refrigerator or onto the floor, as this can damage the flooring or cause a short circuit if it gets to the wiring.
What to do if the ice does not melt?
If the ice crust is too thick and does not melt even after 10 hours, check whether the door was tightly closed before. The seal contour may be broken. The cause may also be a malfunction of the thermostat, which prevents the compressor from going into rest mode. In this case, after defrosting, contact the service.
Sanitization and care of parts
While the ice is melting, it’s time to do deep cleaning. During operation, not only odors accumulate inside the refrigerator, but also bacteria and mold fungi. For washing, it is best to use a baking soda solution (2 tablespoons per liter of water) or special products for household appliances without aggressive abrasives.
Pay special attention to the rubber seal on the door. Black mold is often hidden in its folds, which is difficult to notice immediately. Wipe the folds with a cotton swab dipped in hydrogen peroxide or vinegar solution. A clean seal ensures tightness, which directly affects energy consumption.
- 🧼 Wash plastic shelves with warm water and a mild detergent, avoiding hot water (>50°C).
- 👃 To eliminate persistent odors, use activated carbon or special absorbers.
- 🔌 Carefully vacuum the rear condenser grille (at the back of the refrigerator) to remove dust and fluff.
After washing, all parts should be completely dry. Do not assemble the refrigerator wet, otherwise the moisture will quickly turn into a new layer of ice when turned on. Leave the doors open for another hour after finishing cleaning to allow air circulation to complete the drying process.
If you find a yellow coating on the walls, do not use chlorine bleaches - they can corrode the plastic. It is better to use citric acid or specialized wipes for kitchen appliances. Regular care prevents the appearance of stubborn stains that are then impossible to wash off.
⚠️ Attention: When using chemical cleaning products, be sure to rinse them thoroughly with water. Residues of “chemicals” can be absorbed into the plastic and subsequently end up in food, which is dangerous to health.
Starting the refrigerator after defrosting
When the insides are sparkling clean and dry, you can begin assembling and starting. Replace all shelves, drawers and containers. Make sure they fit snugly and correctly according to the markings on the sides. An incorrectly installed drawer may block air circulation.
Plug in the refrigerator. In the first minutes of operation, it may make more noise than usual - this is normal, the compressor is gaining momentum. Don't load your cameras with food right away! An empty refrigerator takes time to reach operating temperature. This usually takes from 2 to 6 hours, depending on the model and ambient temperature.
For electronically controlled models (Biryusa often equipped with displays on the door), a reset or calibration may be required after switching on. If error indicators are on the display, consult the instructions. Often, after defrosting, the sensors return to normal on their own after 10–15 minutes of operation.
Check the operation of the No Frost system (if it has one). An hour after switching on, no drops of water should be visible inside on the back wall of the main compartment (for a drip system) or a strong air flow should be felt (for No Frost). If everything is working properly, you can start filling the chambers.
Frequent errors and prevention of icing
One of the most common mistakes is loading hot products. Soup that has just boiled should not be put in the refrigerator, even if it really needs to be cooled. This leads to a sharp jump in temperature, increased humidity and, as a result, the rapid formation of an ice coat. Allow the food to cool to room temperature.
Also, users often forget to check that the door is closed tightly. If crumbs or a label from a bag are stuck between the seal and the body, the seal is broken. Warm, humid air from the kitchen constantly flows inside, and the system does not have time to dry it, which leads to ice accumulation.
- ❌ Do not store food in open containers - the moisture evaporates and settles on the walls.
- ❌ Do not overcrowd the refrigerator - air should circulate between the products.
- ❌ Do not ignore the first signs of breakdown (constantly running motor, puddles under the door).
The regularity of defrosting depends on the intensity of use. If you have a large family and the refrigerator is opened dozens of times a day, carry out the procedure every 6 months. For single users or models with full No Frost once a year is enough.
Questions and answers (FAQ)
How long does it take on average to defrost a two-chamber Biryusa?
The time depends on the thickness of the ice and the temperature in the room. Typically the process takes 4 to 8 hours with natural melting. If the layer of ice is small, 2–3 hours may be enough.
Can you use a hair dryer to speed up the process?
You can use a hair dryer, but with great caution. Turn on only warm air, keep the hairdryer at a distance of at least 30 cm from the plastic and do not blow for a long time at one point so as not to melt the parts.
Is it necessary to defrost a refrigerator with a No Frost system?
Yes, it is necessary. Although the No Frost system prevents ice from freezing on food, dust, bacteria and odors still accumulate inside the cabinet. Once a year, complete hygienic defrosting and washing is required.
What to do if after defrosting the refrigerator does not freeze?
Let it stand turned off for another 30-60 minutes, then turn it on again. If the cold does not appear within 2-3 hours, the sensor may have been damaged during defrosting or a power surge may have occurred. A specialist diagnosis is required.
How often should you wash the drainage hole?
It is recommended to check and, if necessary, clean the drainage every time you defrost. This will only take a couple of minutes, but will save you from the formation of an ice plug and water leaks on the floor.
