Modern two-chamber units of the brand Biryusa, even equipped with the No Frost system, periodically require a complete shutdown for hygiene procedures and maintenance. Owners often wonder how to properly organize this process so as not to damage the compressor and maintain the integrity of the internal plastic. Despite the presence of automatic defrosting systems in the evaporator, static and odors can accumulate, requiring manual intervention.
Incorrect defrosting can lead to serious consequences, including deformation of seals or failure of temperature sensors. It is important to understand that defrost cycle is not just ice, but a set of measures to care for a complex household appliance. Ignoring safety rules when working with electrical wiring and refrigerant is unacceptable.
In this article we will analyze in detail the algorithm of actions for models with different types of cooling. You will learn how long the process takes, what products are safe for cleaning cameras, and how to avoid common mistakes that inexperienced users make. Compliance with technology will extend the life of your refrigerator.
Preparation for the defrosting procedure
Before starting any manipulations, it is necessary to empty the refrigerator and freezer compartments of food. If it’s winter outside, the contents can be taken out to the balcony, having previously been packed in boxes. In the warm season, food is placed in thermal bags or basins, lined with ice to prevent spoilage.
The next critical step is to completely disconnect the unit from the electrical network. Simply turning the temperature dial to zero is not enough - you need to unplug the plug from the socket. This guarantees your safety and prevents the compressor from starting accidentally during washing. It is also worth moving the refrigerator away from the wall, providing access to the back wall.
⚠️ Attention: It is strictly forbidden to use sharp objects (knives, chisels) to chip ice. Damage to the cooling circuit or evaporator will lead to a freon leak and expensive repairs, which are often not economically feasible.Prepare all the necessary supplies in advance: soft microfiber rags, basins for collecting water, sponges and detergents. Determine the location of the water drain in advance so as not to flood your neighbors or damage the flooring in your own kitchen. Correct workplace preparation will save you time and nerves.

The process of defrosting a two-chamber Biryusa depends on the type of cooling system. If you have a model with a drip system in the refrigerator compartment and manual defrosting in the freezer, the algorithm will differ from Full No Frost models. In any case, after disconnecting from the network, the doors must be left open.
To speed up the process of natural melting of ice, you can use safe methods. Place containers of hot water inside the chambers. The steam will speed up the melting, but be careful not to splash the water onto the plastic. You can also direct a flow of warm (not hot!) air from the fan towards the freezer.
- 🧊 Install wide trays at the bottom of the chambers to collect melting water.
- 🚪 Leave the refrigerator and freezer doors completely open for the entire procedure.
- 🧽 Prepare soft rags for wiping the internal shelves and walls.
- ⏳ Wait until the ice crust disappears completely, do not rush the process mechanically.
If the ice does not come off, you can carefully use a plastic spatula specially designed for cleaning ice. However, it is better to let the ice melt on its own so as not to damage the fragile elements of the system air circulation. In models with No Frost, it is important not to flood the air ducts located on the rear wall with water.
☑️ Defrosting algorithm
Done: 0 / 5Features of defrosting models No Frost and drip system
Owners refrigerators Biryusa with the No Frost system are often believed that their units do not require defrosting at all. This is a misconception. Although it is rare for an ice coat to form on the evaporator, dust, mold and unpleasant odors can accumulate inside the chamber. In addition, the drainage hole that removes condensate may become clogged and require cleaning.
In models with a drip system (crying evaporator), moisture flows down the back wall into the groove. It is important here to check the integrity of the groove and the tube. If water stagnates at the bottom of the refrigerator compartment, the drainage is clogged. It must be carefully cleaned using a brush or soft wire.
System type Frequency of defrosting Main purpose Risks if ignored Drip (Low Frost) 1-2 times a year Ice removal, hygiene Seal failure, odor No Frost (Full) 1 time a year Hygiene, drainage cleaning Mold, sensor failure, noise Manual defrosting As ice builds up Removing the snow coat Compressor overheating, food spoilage When cleaning the No Frost system, pay special attention to the fan, if you have access to it. A fan clogged with dust stops cooling the chamber effectively, which leads to an increase in the compressor operating cycle. Carefully remove the dust with a soft brush, being careful not to damage the blades.
Why does ice appear in No Frost?
Ice in the No Frost system may appear due to a loose door, a damaged seal, or a malfunction of the defrost heating element. In these cases, moisture from the air enters the chamber and freezes.
How to wash the inside of the refrigerator: safe products
For washing the internal chambers Biryusa it is strictly not recommended to use aggressive chemicals containing chlorine or strong acids. Strong odors can be absorbed into the plastic and subsequently transferred to the food. Also, aggressive substances can corrode the plastic or make it cloudy.
The optimal solution is to use a warm solution of baking soda or laundry soap. Baking soda perfectly disinfects and removes odors without leaving toxic traces. For a liter of warm water, just add 2 tablespoons of soda. To remove greasy stains, you can use dishwashing detergent, but it must be rinsed off very thoroughly.
- 🍋 A solution of citric acid removes scale well and is refreshing.
- 🧼 Laundry soap effectively fights grease deposits.
- 💧 Clean warm water is required for the final rinse.
- 🚫 Vinegar can be used, but with caution due to the persistent odor.
After washing, all surfaces must be wiped dry with a clean cloth. Remaining moisture can cause a new layer of ice to form immediately after switching on or cause bacteria to grow. Pay special attention to the corners and joints of shelves, where water stagnates most often.
⚠️ Attention: Do not use abrasive powders or hard brushes. They leave micro-scratches on the plastic, in which dirt will subsequently accumulate and bacteria will multiply, which will make further cleaning much more difficult.Drying and assembling the refrigerator after washing
The final stage of defrosting is the thorough drying of all elements. Even if the surface appears dry visually, moisture may remain in microcracks and joints. Leave the doors open for another 30-60 minutes after washing, ensuring a draft in the room.
While the body is drying, you can wash the removable elements: shelves, vegetable drawers, egg trays. It is better to wash them separately in the bathroom under running water. Glass shelves should not be placed under hot water immediately after cold - the temperature difference may cause the glass to burst. Let them warm to room temperature.
Make sure the drainage hole is clear of water and debris. If you cleaned it with a brush, check the passage by pouring a little water (about 50 ml) into the groove. It should quickly go into the drain hose. This ensures that there are no puddles at the bottom of the refrigerator in the future.
Correct first turn on after defrosting
After you We returned all the shelves and drawers to their places, the refrigerator is ready to be turned on. However, there is no need to rush to load products. First, plug in the empty unit and let it idle. This will allow the system to reach operating temperature conditions.
The operating time before loading depends on the model and the ambient temperature in the room. Usually 2-4 hours is enough. During this time, the compressor will turn off automatically, signaling that the set temperature has been reached. Only after this can you begin to fill the chambers with food.
If you notice that after turning on the refrigerator runs continuously for more than 6-8 hours without turning off, this may indicate a problem. Perhaps the door is not completely closed, or there is air left in the system (if repairs were made), or the thermostat is faulty. In this case, diagnostics are required.
Common mistakes when defrosting and how to avoid them
One of the most common mistakes is using a hair dryer to speed up defrosting. Hot air can warp the thin plastic of the interior chamber or damage the door seals. If you do use a hair dryer, turn on only cold air and keep the device at a distance of at least 30 cm.
Another mistake is turning on the refrigerator immediately after washing, without waiting for the contacts and electrical components to dry. Moisture on the control board or terminals may cause a short circuit. Always check the dryness of all accessible electrical parts before connecting to a 220V network.
- ❌ Trying to break off the ice with a knife (risk of freon breakdown).
- ❌ Using boiling water to speed up (risk of plastic cracks).
- ❌ Loading warm food into the switched on refrigerator.
- ❌ Ignoring cleaning the condenser from the back (risk of overheating).
Also, users often forget to check the condition of the sealing rubber. During defrosting, it should be carefully inspected for cracks and dirt. A dirty seal does not provide a tight seal, which makes compressor work harder. Wipe the rubber with a soft sponge and soapy water.
How long should the two-chamber Biryusa dry after defrosting?
30-60 minutes with the doors open in a ventilated room is enough. The main thing is to make sure that there is no visible moisture on the walls and shelves.
Is it possible to wash the Biryusa refrigerator with window cleaners?
Not recommended. Glass cleaners often contain ammonia and fragrances, which can be toxic when in contact with food and are absorbed into plastic.
What to do if an unpleasant odor appears after defrosting?
Wipe the internal surfaces with a solution of citric acid or use special odor absorbers (charcoal, soda in an open container). Check the drainage hole for blockages.
Is it necessary to defrost the Biryusa refrigerator with No Frost?
Yes, at least once a year for general cleaning, disinfection and checking the ventilation system, even if there is visually no ice.
