Regular maintenance of household appliances is the key to its long and stable operation, especially when it comes to such a complex unit as a two-chamber refrigerator. Many owners of brand equipment mistakenly believe that modern cooling systems completely eliminate the need for manual intervention, however, even models with the No Frost or drip defrosting function require periodic complete disconnection from the network. Ignoring this process can lead to the formation of a thick ice crust, which not only reduces the useful volume of the chambers, but also forces the compressor to work with increased load, which inevitably affects the bills for Biryusa They mistakenly believe that modern cooling systems completely eliminate the need for manual intervention, however, even models with the No Frost or drip defrosting function require periodic complete cleaning and disconnection from the network.

The process of defrosting two-chamber models Biryusa has its own technical features that distinguish it from servicing old single-chamber “freezers”. A dual-circuit system or the presence of separate evaporators in the freezer and refrigerator compartments require a more careful approach to removing moisture and ice. Incorrect actions, such as using sharp objects to chip ice or using chemicals, can cause irreparable damage to the heat exchanger, the repair of which is often not economically feasible. Therefore, it is extremely important to follow a proven algorithm of actions that will ensure the safety of all units of the unit.
In this article we will analyze in detail all the stages of preparation, the thawing process itself and the subsequent start-up of the equipment. You will learn how long this procedure takes for various modifications, how to properly prepare products, and what actions are strictly prohibited by manufacturers. Following these recommendations will allow you to maintain efficiency the operation of your refrigerator at the maximum level and extend its service life for many years without the need for costly repairs.
Preparation for defrosting refrigeration equipment
The first and most important step is proper preparation, which begins long ago until the device is physically disconnected from the power supply. You need to plan in advance a time when you can leave the refrigerator idle for several hours without worrying about the safety of your food. The ideal option is a situation when there is a minimum of stock left in the chambers, which usually happens before the next trip to the store or after the holidays, when food supplies are significantly depleted.
It is necessary to empty both chambers - both the refrigerator and the freezer - of all products. All perishable products should be transferred to a cold place, for example, on a balcony (in winter) or in thermal bags with ice. Shelves, vegetable drawers, egg containers and other removable elements made of plastic and glass also need to be removed. They will be washed and disinfected separately while the chambers are free for defrosting and wet cleaning.
⚠️ Attention: Never try to speed up the defrosting process by leaving the doors open in a draft or using a hair dryer at maximum power directed into the chamber. A sudden temperature change can cause deformation of plastic parts and damage seals.
After the chambers are released, the moment of shutdown occurs. Locate the power cord and unplug it from the outlet. Some models Biryusa access to the outlet may be difficult if the unit is mounted close to a wall, so make sure you have room to maneuver. Do not pull sharply on the wire; hold on to the plug body. If your model has a separate switch on the case (which is rare, but occurs in older series), move it to position Off.
☑️ Preparing for defrosting
Technique for safely thawing ice
The safest defrosting method recommended by the manufacturer is natural thawing with the doors open. You will just need to leave the refrigerator alone for a few hours. The time required for the ice to completely disappear directly depends on the thickness of the ice, the room temperature and the model of your unit. For two-chamber models Biryusa this process usually takes from 3 to 6 hours, but in rare cases with a very thick layer of ice it can take up to 10-12 hours.
Since a large amount of water is formed when ice melts, it is necessary to prepare a liquid collection site in advance. Cover the floor around the refrigerator with old towels, rags, or use special absorbent diapers. You can put a thick cloth at the bottom of the freezer that will absorb the flowing water, preventing it from spreading across the kitchen floor. Regularly check the condition of the rags and change them when they get wet getting wet.
⚠️ Attention: It is strictly forbidden to use knives, screwdrivers, metal spatulas or any other sharp objects to chip ice. Damage to the evaporator tubes located behind the plastic wall will lead to a refrigerant leak and complex, expensive repairs.
If you want to speed up the process a little, you can use safe methods that do not involve mechanical stress. For example, you can place containers with hot water in the chambers (but not boiling water, so as not to melt the plastic). It is also permissible to use a fan directed at open doors to circulate air. However, remember that any attempts to “help” the ice melt faster should be done in moderation. The main goal is to maintain the integrity of the internal coating of the chambers and thermal insulation.
Cleaning and disinfection of internal chambers
While the ice is melting, it’s time to thoroughly clean the removable elements and internal surfaces. Removed shelves, racks and plastic containers are best washed in a bathtub or large basin using warm water and a mild detergent. To remove stubborn dirt or dried-on stains, you can use baking soda diluted in water to a paste consistency. This is a safe abrasive that does not scratch glass and plastic, unlike aggressive chemistry.
The inner walls of the chambers, which have already been freed from ice and have dried, also need attention. Wipe them with a soft sponge soaked in a weak solution of vinegar or a special refrigerator cleaner. This will help eliminate unpleasant odors and kill bacteria that may have grown in hidden corners. Pay special attention to the rubber seals on the doors: dirt and mold often accumulate in their folds, which can be easily removed with a cotton swab dipped in disinfectant solution.
After washing, all parts must be thoroughly rinsed with clean water and Wipe dry with a towel. Wet shelves and drawers cannot be immediately put back into the refrigerator, as excess moisture will increase the humidity inside the chambers after switching on, which will cause more rapid formation of new ice. Allow all elements to dry completely at room temperature or wipe them with a dry cloth until they are completely dry. dryness.
Care for the system water removal and drainage
One of the often ignored procedures when defrosting two-chamber refrigerators Turk is cleaning the drainage system. In models with a drip defrosting system (crying evaporator), moisture flows into a groove on the back wall of the refrigerator compartment and goes through a hole into a container above the compressor, where it evaporates. Over time, debris, crumbs, or mucus can accumulate in this hole, causing a clog and a puddle under the crisper drawers.
During defrosting, when the compartments are empty and dry, locate the drainage hole on the back wall of the refrigerator compartment. Clean it carefully using a special brush (often included) or a soft wire wrapped in cotton wool. Do not use hard objects that could pierce the tube. After mechanical cleaning, pour a little warm water into the hole to check the permeability. If the water drains quickly and smoothly, then the system is functioning correct.
It is also worth checking the condensate tray, which is located above the compressor in the lower rear part of the unit. You may need to remove a protective cardboard or metal panel to access it. There should be no dirt or silt in the tray. If black mucus has accumulated there, it must be removed, as it is a breeding ground for bacteria and a source of unpleasant odor. Rinse the tray with hot water and soda and install it back, making sure that the drainage tube is correctly tucked into it refilled.
| Work stage | Required tools | Completion time | Importance |
|---|---|---|---|
| Releasing the chambers | Thermal bags, packages | 15-20 min | High |
| Natural defrosting | Rags, basins | 4-10 hours | Critical |
| Washing shelves and drawers | Sponge, detergent | 30-40 min | High |
| Cleaning the drainage | Brush, syringe | 10-15 min | Medium |
| Final assembly | Dry rags | 15-20 min | High |
Starting the refrigerator after defrosting
After completion of all cleaning procedures and complete drying of the internal surfaces, the assembly and first start-up stage begins. Make sure that the inside of the chambers is completely dry and there is no smell of detergents. Place all shelves, racks and drawers in their proper places. Check that they are firmly secured so that they do not move when loaded with food. The doors can be left ajar for the time being for final ventilation if strong-smelling detergents were used.
Connect the refrigerator to the power supply. In modern models Biryusa with electronic control, after switching on, a sound signal may be heard and the indicators on the display will light up. Let the appliance run idle (without food) for 1-2 hours. This is necessary for the unit to reach operating temperature and for the automation to turn off the compressor. Loading warm food into the refrigerator will cause the compressor to work without stopping, which is harmful for motor.
When the temperature in the chambers stabilizes (in the refrigerator about +4...+5°C, in the freezer -18°C and below), you can gradually load the products. Do not fill the chambers completely during the first hours of operation. Distribute food evenly without blocking the vents if your model has them. Monitor the operation of the unit during the first day: it should turn on and off cyclically, without excessive noise or vibration.
Typical errors and precautions
During the defrosting process, users often make mistakes that can shorten the life of the equipment. One of the most common is haste. An attempt to speed up defrosting with a knife or hot water from a kettle poured directly onto the ice often ends in damage to the plastic box of the freezer or, worse, a breakdown of the evaporator. The heat exchanger in modern models Biryusa is often made of aluminum and has very thin walls hidden behind plastic, so mechanical impact on the ice is unacceptable.
Another mistake is ignoring cleaning the back of the unit. Dust accumulating on the condenser (grid at the back) and around the compressor impairs heat transfer. This causes the refrigerator to run longer and consume more electricity. During defrosting, when the appliance is turned off, be sure to vacuum the back wall or carefully remove dust with a dry brush. This is a simple procedure that significantly improves energy efficiency.
⚠️ Attention: If after defrosting and turning on the refrigerator makes unusual sounds, does not cool, or an error code appears on the display, do not attempt to repair it yourself. Contact an authorized service center, as independent intervention may void your warranty.
It is also worth mentioning the importance of regularity. Don't wait until the layer of ice in the freezer is as thick as your finger. Defrost regularly, once every 6-12 months, depending on the humidity in your region and the frequency of opening the doors. Regular maintenance prevents situations where ice blocks the door or prevents the drawers from closing, and maintains the original volume of usable space inside chambers.
What should you do if water appears inside after defrosting?
If, after turning on, you again find water inside the refrigerator compartment, check to see if the drainage hose is pinched when installing the drawers. It is also possible that the drainage hole is clogged again and requires repeated cleaning with a brush.
Frequently asked questions (FAQ)
How long should you keep the Biryusa refrigerator turned off?
The optimal shutdown time is from 4 to 10 hours. The minimum time is until visible ice completely melts (usually 3-4 hours). However, it is recommended to wait another 1-2 hours after the ice melts so that all internal surfaces and hard-to-reach areas are completely dry. This will prevent the instant formation of new ice after switching on.
Is it possible to defrost a Biryusa refrigerator with a No Frost system?
Yes, even models with a No Frost system require periodic defrosting, although much less frequently (once every 1-2 years). This is necessary for hygienic cleaning, removing dust from the condenser and clearing the drainage hole, which can become clogged with mucus or debris, leading to leaks.
Why does the refrigerator not turn off for a long time after defrosting?
This is normal. After defrosting, the inner walls and food (if you have already loaded the chamber) are at room temperature. The compressor takes time (sometimes up to 24 hours depending on the load and room temperature) to cool the entire volume to the specified parameters. If after a day the operating mode has not returned to normal, it is worth checking the density
