Refrigerators Biryusa series 120 are reliable equipment with a time-tested cooling system, but even the most durable units require regular maintenance. Manual defrosting for such models is not just a maintenance recommendation, but a necessity that prolongs the life of the compressor and prevents the formation of ice plugs in the channels. Unlike systems No Frost, here moisture from the products settles on the walls of the evaporator, gradually turning into a dense ice crust.
Ignoring the need to remove ice leads to the compressor working without interruption, trying to compensate for the impaired heat transfer. This not only increases energy consumption, but also creates a risk of motor overheating. Owners of the model Biryusa 120 need to clearly understand the algorithm of actions so that the procedure goes quickly and does not cause harm to the internal components.
The thawing process takes time and preparation, but the result is worth it: the equipment starts working quietly again, effectively cooling products and delighting with the cleanliness of the chambers. Below we will analyze each stage in detail, from turning off the device to restarting it, paying attention to the nuances that beginners often miss.
The main rule of successful defrosting is full compliance with the sequence of actions. You should not try to speed up the process by mechanically chipping the ice, as this may damage the evaporator tubes. Follow the instructions, and your refrigerator will last for many years without serious breakdowns.
Preparing the refrigerator compartment for thawing
The first step is to clear the internal space of food. You need to plan the defrosting time in advance so that you can use perishable supplies or temporarily transfer them to a cold place. If it is winter outside, you can take the food out to the balcony, after first making sure there is no precipitation.
It is important to remove all shelves, drawers and containers from the refrigerator compartment. Glass shelves and plastic elements should be washed separately with warm water and a mild detergent. This will prevent chemicals from getting inside the unit and ensure hygienic storage of products in the future.
Pay special attention to the rubber seals. While the doors are open, wipe them with a damp cloth, removing crumbs and dirt. Often it is in the folds of rubber that mold accumulates, which can become a source of unpleasant odor after turning on the appliance.
☑️ Preparing for defrosting
Check whether the refrigerator is level. If the legs become loose during use, now is the time to adjust their position. A stable position of the case is important for proper circulation of the refrigerant and operation of the water drainage system.
Disconnecting the power and removing the ice
After the chamber is empty, it is necessary to disconnect the refrigerator from the power supply. Unplug the plug from the outlet, but do it carefully, holding the plug itself and not the wire. Sharp jerks can damage the contacts or cable insulation.
Now you need to open the refrigerator doors and leave them in that position. To speed up the process, you can put a pan of hot water inside, but not boiling. Steam will help soften the ice crust on the evaporator faster. It is strictly forbidden to use a hair dryer, as hot air can deform plastic parts or damage tubes.
⚠️ Attention: Never use sharp objects (knife, screwdriver, scraper) to chip ice! Damage to the evaporator tube will lead to freon leakage and expensive repairs.
The defrosting time depends on the thickness of the ice layer and the room temperature. This process usually takes from 3 to 6 hours. Do not rush to close the doors ahead of time - the moisture must completely evaporate or be removed.
Why should you not rush the process?
Mechanical removal of ice or the use of chemical reagents can lead to microcracks in plastic and metal, which will appear only after several months of operation.>
If the ice does not come off yourself, you can carefully place a towel soaked in warm water under it. This will help soften the base of the ice crust without the risk of damaging the surface.
Removing water and cleaning the drainage system
When the ice has completely melted, a large amount of water will form at the bottom of the refrigerator compartment and on the floor. Prepare rags and containers to collect liquid in advance. In the model Biryusa 120 water can flow into a special gutter, but often part of it remains on the floor of the chamber.
Wipe all surfaces thoroughly with a dry, clean rag. Pay special attention to the corner where the drainage hole is located. It is located on the rear wall and serves to drain condensate. If it is clogged, water will accumulate under the vegetable drawers.
To clear the drainage, you can use a special brush or soft wire with cotton wool at the end. Carefully insert the tool into the hole and make several rotational movements. After this, pour in some warm water to make sure there is free flow.
| Element | What to clean | Frequency | Risk of contamination |
|---|---|---|---|
| Chamber walls | Soft sponge, soap solution | Each defrost | Mold, smell |
| Drainage hole | Brush, warm water | Each defrosting | Clogs, puddles |
| Seals | Damp cloth | Once a month | Loss of tightness |
| Shelves | Warm water, soda | Every defrost | Bacteria |
If the water does not drain, a plug may have formed in the tube from fat or food debris. In this case, you can use a rubber bulb to apply pressure and push through the clog. Proceed carefully so as not to damage the plastic channel.
Washing internal surfaces and eliminating odors
Cleanliness inside the refrigerator is the key to freshness of food. To wash the inner walls, it is best to use a baking soda solution (1 tablespoon per liter of water) or a special household appliance product. Avoid aggressive chemicals with chlorine, which can damage the coating.
Thoroughly rinse all removed shelves and drawers. It is better to dry plastic parts at room temperature, avoiding direct sunlight and heating devices, so that the plastic does not turn yellow or deform.
If there was a smell of spoiled food in the refrigerator, wipe the walls with a weak solution of vinegar. It perfectly disinfects and neutralizes organic odors. After treatment, be sure to let the surfaces dry.
Don't forget to wipe the outer part of the case. Metal surfaces can be easily cleaned with special polishes, and plastic elements can be easily cleaned with a damp cloth. A refrigerator that is clean on the outside looks more aesthetically pleasing and heats up less in the sun.
Rules for first switching on after defrosting
After completing all cleaning and drying procedures, the startup stage begins. It's important to take your time here. Even if everything is visually dry, moisture could remain in hard-to-reach places. Let the refrigerator stand with the doors open for another 30-60 minutes.
Connect the appliance to the network. In the first minutes of operation, the compressor may make louder sounds than usual - this is normal for a system with capillary tubetypical for Turks 120. After 10-15 minutes, the noise level should stabilize.
⚠️ Attention: Do not load food into the refrigerator immediately after turning it on! Let the equipment run idle for at least 2-3 hours so that it reaches operating temperature conditions.Check the operation of the thermostat. Set the knob to the middle position (usually number 3 or 4). After an hour, check the temperature inside the chamber - it should be noticeably lower than room temperature. If the cold does not accumulate, there may be air left in the system or there is a malfunction.
Frequent errors when defrosting Biryusa 120
Many users make typical mistakes that negate all the benefits of the procedure. One of the most common is an attempt to speed up thawing using a hairdryer or hot water poured directly onto the ice. A sharp temperature change is dangerous for materials.
Another mistake is turning on the device with wet walls. Residual moisture will instantly freeze, forming a new ice crust that will interfere with the normal operation of the evaporator. Always wipe the camera dry.
Also, do not leave the refrigerator to defrost unattended for a long time if there are animals or small children in the house. An open door can cause personal injury or property damage.
Avoid using abrasive sponges for cleaning. Microscopic scratches on plastic become an ideal breeding ground for bacteria, which are then very difficult to remove.
How often should you defrost a refrigerator
The frequency of defrosting depends on the air humidity in the room and the intensity of use of the equipment. For a model Biryusa 120 with a manual defrosting system, the optimal interval is once every 3-4 months.
If you notice that the layer of frost on the back wall exceeds 5-7 millimeters, this is a signal for immediate defrosting. A thicker layer of ice significantly reduces cooling efficiency and increases the load on the engine.
In the summer, when humidity is higher and food is loaded more often, you will have to defrost the refrigerator more often. In winter, this interval can increase to 5-6 months.
Regular maintenance will avoid situations when the refrigerator stops freezing due to blockage of the channels with ice. Monitor the condition of the unit, and it will respond to you with stable operation.
Is it possible to defrost a refrigerator without unplugging it?
No, this is strictly prohibited. Defrosting is only possible when the power supply is completely turned off. A running compressor will try to compensate for the heat from the melting ice, which will lead to its overload and possible failure.
What to do if the refrigerator does not freeze after defrosting?
Check whether the doors are tightly closed and whether the thermostat is installed correctly. If after 3-4 hours of operation in empty mode the cold does not appear and the compressor is working, there may be a freon leak due to careless cleaning or a thermostat failure.
Do you need to lubricate the seals after washing?
Yes, after drying, it is recommended to wipe the rubber seals with silicone grease or glycerin. This will maintain their elasticity, prevent cracking and ensure the door fits tightly.
Is the smell of plastic dangerous when you first turn it on?
A slight odor may be present if you have used new cleaning products or there has been moisture in the chamber. However, a strong chemical smell may indicate overheating of the wiring. In this case, the device must be turned off immediately.
