Owners of domestic equipment often wonder how to properly defrost the Biryusa refrigerator so as not to damage the compressor or cooling system. Despite the apparent simplicity of the procedure, incorrect actions can lead to cracks in the evaporator or failure of the thermostat. Modern models, even with the No Frost system, require periodic maintenance, and classic units with a drip system require regular manual defrosting.
The ice thawing process is necessary to maintain energy efficiency the device. A thick layer of ice on the walls of the chamber acts as a heat insulator, causing the motor to wear out. In this article, we will analyze in detail the stages of preparation, the process of shutting down and then starting up the equipment, taking into account the design features of the various series of the brand.
It is important to understand that each type of cooling system has its own nuances. If you have a manual or drip model, the approach will be different from servicing units with automatic defrost. Ignoring these differences may shorten the service life refrigeration circuit. Let's look at how to act competently and safely for your equipment.
Preparing for defrosting and turning off equipment
The first step is to completely empty the refrigeration chambers of food. Prepare cooler bags or bowls of ice in advance so that perishable goods do not have time to spoil. Remove all shelves, drawers and containers - they should be washed separately in warm water and a mild detergent. This is the ideal time to audit stocks and throw out expired products.
Next, you need to turn off the power to the unit. Unplug the plug from the socket. Do not try to defrost a running refrigerator by simply increasing the temperature on the thermostat, as this will place excess load on the compressor, which will try to compensate for heat loss. For models Biryusa with mechanical control, it is important to ensure that the control knob is set to the "0" or "Off" position before disconnecting from the network.
⚠️ Attention: Never use sharp objects (knives, screwdrivers, scrapers) to chip ice inside the chambers. Thin evaporator tubes in Biryusa refrigerators are located very close to the inner wall, and their damage will lead to freon leakage and expensive repairs.
Absorbent rags should be placed under the refrigerator and freezer doors or flat containers should be placed to collect melt water. This is especially true if the floor in the room does not have a moisture-proof coating or is made of materials that are afraid of water (laminate, parquet). Water can leak not only from the chambers, but also from the drainage channel if it is clogged.
☑️ Preparing for defrosting
Natural thawing and accelerating the process
The safest way to remove ice is natural thawing. Leave the refrigerator and freezer doors open. Depending on the amount of ice and the temperature in the room, this process can take from 3 to 24 hours. For classic models Biryusa with large ice in the freezer, the time can be increased.
If time is limited, you can use safe acceleration methods. Place containers with hot water inside the chambers (but not boiling water, so as not to damage the plastic). Close the door for 10-15 minutes, then repeat the procedure. The steam will soften the ice and it will begin to come off faster. You can also use a hairdryer, but you need to direct the stream of warm air carefully, without lingering long on one point of the plastic.
- 🧊 Use a spray bottle with warm water to spray the ice crust - this speeds up the melting.
- 🌡️ Do not use heating devices (heaters, heat guns) in close proximity to the plastic to avoid deformation.
- 💧 Change the water in the bowls as it cools to maintain the temperature gradient.
Make sure that the water does not overflow the edge of the containers. In some Biryusa models, the drainage hole is located on the back wall of the refrigerator compartment. If water sits inside and does not drain, the drain may be clogged. It can be carefully cleaned with a special brush or soft wire after completion of the main defrosting.
Why can’t you pour boiling water?
It is absolutely forbidden to pour boiling water directly onto the ice or the walls of the chamber. Sudden temperature changes can cause cracks in the plastic housing or, worse, in the metal evaporator. In addition, hot water can damage the rubber seals on the doors, making them less elastic, which will lead to a loose fit and loss of cold in the future.
Features of defrosting the No Frost system
Many owners mistakenly rely on the name of the system No Frost ("without frost") and believe that defrosting such Biryusa refrigerators are not needed at all. This is not entirely true. Although the evaporator in such models is hidden and defrosts automatically thanks to the built-in heating element, the interior of the chamber still requires hygienic treatment. It is recommended to carry out complete defrosting and washing at least once a year.
In No Frost systems, water from the evaporator defrost is collected in a special tray above the compressor and evaporates naturally. However, if the drainage system becomes clogged with debris or mold, water may leak into the chamber or onto the floor. Therefore, when defrosting, be sure to check the cleanliness of the drainage hole, which is usually located on the back wall.
For models with a “Zero Humidity” or “Freshness” zone (for example, series Biryusa 133 or 355), it is important to thoroughly wipe the air supply channels. Clogged air ducts impair circulation, which leads to uneven cooling and increased load on the fan.
⚠️ Attention: In refrigerators with the No Frost system, it is strictly forbidden to try to remove the back plastic panel inside the freezer yourself unless necessary. Behind it are fragile sensors and a fan that can easily be damaged by inept actions.
Washing and disinfection of internal surfaces
After all the ice has melted and the water has been removed, the washing stage begins. Use a weak solution of baking soda, vinegar, or specialized refrigerator cleaners. Avoid aggressive chemicals, chlorine-containing substances and abrasive powders, which can scratch the plastic or leave a lasting odor.
Pay special attention sealing rubber bands on the doors. Dirt and mold often accumulate in the folds, which spoils the smell of food. Wipe them with a damp cloth; you can use a cotton swab for hard-to-reach places. Clean rubber bands provide a tight seal, which is critical for saving energy.
Removable elements - glass shelves and plastic drawers - are best washed in the bathtub or shower. Rinse them thoroughly to remove any remaining detergent and wipe dry before replacing them. Wet shelves may freeze to the fastenings when first started.
| Refrigerator element | What to wash | What not to wash | Processing frequency |
|---|---|---|---|
| Internal walls | Soda solution, special means | Abrasives, chlorine, boiling water | Once every 6-12 months. |
| Sealants | Wet wipe, soapy solution | Oils, solvents | Once every 3-4 months. |
| Shelves and drawers | Warm water, dish gel | Hot water (for glass) | At each defrost |
| Outer body | Polishing agent, water | Solvents, gasoline | As it gets dirty |
After Before washing, be sure to wipe all surfaces dry with a clean rag. Remaining moisture may cause an unpleasant odor or mold when the doors are closed. Allow the refrigerator to dry completely while open for 30-60 minutes.
Correct switching on after defrosting
Assembling a refrigerator is a crucial moment. Place all shelves and drawers in their proper places. Make sure they are straight and locked. Now you can connect the unit to the network. However, it is not recommended to load food immediately.
Let the Biryusa refrigerator run idle for 1-2 hours. During this time, the chambers will cool down to the set temperature, and the thermostat will turn off the compressor. Only after reaching the operating mode can you add food. A sudden load with warm food will force the motor to work without stopping for a long time.
If you transported the refrigerator or tilted it strongly during defrosting (for example, to wash the floor underneath), it should stand upright for at least 2-4 hours before turning it on. This is necessary so that the compressor oil flows back into the compressor crankcase. Starting with oil in the circuit can lead to water hammer and damage to the unit.
Typical errors and frequently asked questions
Often users try to speed up the process by using “heavy artillery” - they pick at the ice with a knife or pour boiling water. As already mentioned, this is a direct path to repair. It is also a mistake to turn on the equipment immediately after washing, without allowing it to dry. Moisture in electrical contacts can cause a short circuit.
Another common problem is an unpleasant odor after defrosting. It appears if the refrigerator is not dried out or the drainage is not cleaned. To eliminate the smell, you can use activated carbon, soda in an open container, or special odor absorbers.
- ❌ Do not turn on the light inside the chambers to speed up the melting - the lamps heat poorly, and the risk of burning out or melting the lampshade is high.
- ❌ Do not leave the refrigerator to defrost unattended if there are animals or small children.
- ✅ Regular defrosting extends the life of the Biryusa refrigerator by 5-7 years.
Following these simple rules will allow your equipment to work long and efficiently. Remember that prevention is always cheaper than repairs. Regularly check the condition of the seals and the cleanliness of the chambers, and the Biryusa refrigerator will delight you with cold for many years.
⚠️ Attention: Models and technical characteristics of Biryusa refrigerators may vary slightly depending on the year of manufacture. Always check the instructions (operating manual) supplied specifically with your device, especially in the sections on maintenance and electrical parameters.
What to do if the refrigerator does not freeze after defrosting?
If more than 3-4 hours have passed after turning it on and the cold has not appeared, check whether the doors close tightly. If everything is closed, listen to see if the compressor is running. If the motor hums, but there is no cold, or the motor is silent, there may be a freon leak due to careless defrosting or an electronics failure. A call from a technician is required.
How long does it take to defrost the Biryusa refrigerator?
The time depends on the thickness of the ice and the temperature in the room. Typically the process takes from 3 to 10 hours. Complete drying and airing may take another 1-2 hours. Take your time, it’s better to wait longer than to turn on a wet unit.
Is it possible to defrost a refrigerator with a hairdryer?
You can use a hairdryer, but with great caution. Turn on the warm (not hot!) air mode and keep the hair dryer at a distance of at least 20-30 cm from the plastic. Do not heat one point for a long time, so as not to melt the body or damage the evaporator tubes.
Is it necessary to defrost a No Frost refrigerator?
Yes, it is necessary. The No Frost system prevents the formation of ice on the products and the back wall, but hygienic washing and checking the drainage system must be carried out at least once a year to remove bacteria and mold.
Why did an odor appear after defrosting?
The odor can arise from residual water in the drainage channel, insufficiently dried surfaces or the use of unsuitable detergents. Wipe the chambers with a solution of vinegar or citric acid and leave the doors open for ventilation.
