Owning a refrigerator brand Biryusa is often a choice in favor of time-tested reliability, however, even the most durable equipment requires regular and proper care. One of the key maintenance procedures is scheduled defrostingwhich directly affects the energy consumption of the unit and the service life of the compressor. Many users mistakenly believe that modern cooling systems have completely eliminated the need for manual intervention, but in models with manual control or a drip defrosting system, this process remains mandatory.
The accumulation of ice on the evaporator creates a kind of “fur coat” that works as a heat insulator, forcing the motor to work hard to maintain the set temperature. If you ignore the need to remove ice, you risk higher electricity bills and possible failure of expensive components. That is why it is important to clearly understand how to defrost a Biryusa refrigerator correctly, so as not to harm the equipment and maintain food freshness.
In this article we will analyze in detail the algorithm of actions for various models, including popular series 133, 148 and 6224, and also answer frequently asked questions about the procedure time and methods for accelerating ice melting. You will learn why you should not use sharp objects for chipping and how to prepare the camera for a new cycle of work. Following simple rules will help your refrigerator serve for decades without serious breakdowns.
⚠️ Attention: It is strictly forbidden to use knives, screwdrivers or other sharp metal objects to chip ice. Damage to the evaporator tubes will lead to an immediate release of refrigerant and complex, expensive repairs, which are often not economically feasible.
Preparatory stage before defrosting
Before starting any maintenance procedure on an electrical appliance, it is necessary to ensure safety and prepare the work area. The first step should always be power outage unplug this will eliminate the risk of electric shock and stop the compressor from running. After you have pulled out the plug, you should empty the refrigerator and freezer compartments of all products, having previously sorted them.
It is best to temporarily transfer products that you plan to store into basins with cold water, wrap them in blankets or take them out to the balcony if the temperature there is below freezing. For foods that require freezing, you can use insulated bags or containers with ice. It is also necessary to remove all removable elements: shelves, drawers, egg trays and bottle holders. These parts should be washed separately with warm water and a mild detergent to avoid chemicals getting inside the cabinet.
An important preparation point is to protect the floor around the refrigerator. As the ice melts, a significant amount of water is formed, which can ruin the floor covering or leak to the neighbors below. Cover the floor around the unit with old towels, rags, or use wide, flat containers to collect moisture. Also prepare a sponge and soft cloth for subsequent cleaning of the inner surface of the chambers.
☑️ Checklist for preparing for defrosting
Technology for natural thawing of ice
The safest and manufacturer-recommended method for removing ice is natural thawing. After the refrigerator is turned off and the doors of both chambers are open, the melting process starts automatically. Depending on the thickness of the ice layer and the room temperature, a complete cycle can take from 3 to 24 hours. You should not try to artificially speed up this process using a hairdryer or hot water if you are not confident in your actions, since a sharp temperature change is dangerous for plastic and metal.
Models Biryusa with a bottom freezer are often provided with a special gutter for draining melt water, which is brought out or ends removable tray. However, in many cases, the water will simply drain to the bottom of the refrigerator, from where it will have to be scooped up with a mug or removed with a sponge. Make sure that water does not overflow over the edge of the tray and does not get on electrical contacts or the engine compartment.
While the ice is melting, you can start cleaning the removed shelves and drawers. While they are out of the refrigerator, there is an excellent opportunity to inspect them for cracks and thoroughly disinfect them. Use a baking soda solution or special household appliance cleaners. After cleaning, be sure to rinse the parts with clean water and allow them to dry completely before returning them to their place.
Why can't you use a hair dryer?
Using a hair dryer to speed up defrosting creates local overheating of the plastic and can lead to deformation of the internal panels or cracking of the evaporator. In addition, the hot air flow can damage the door seals, reducing their service life. Natural thawing is the only guaranteed safe method for the longevity of equipment.
Is it possible to speed up the defrosting process
Often users have a desire to reduce the downtime of the refrigerator, especially in hot weather, when food quickly deteriorates. There are methods that really help, but they should be used with extreme caution. One such method is to place containers of hot (but not boiling) water on the refrigerator shelves. The steam rising from the water helps the ice melt faster. speed up defrosting, but they should be used with extreme caution. One such method is to place containers of hot (but not boiling) water on the refrigerator shelves. The steam rising from the water causes the ice to melt faster.
Another method is to use a fan. By directing a stream of room temperature air into the open chamber, the air circulation will help the ice melt faster than if it were at rest. However, it is important to ensure that no dust or debris from the floor gets into the camera. Some users also use a spray bottle with warm water to spray ice build-up, but this method requires constant monitoring to ensure that water does not flow into the technical holes.
⚠️ Attention: Never pour boiling water directly onto the ice or chamber walls. A sharp thermal shock can cause cracks in the plastic of the inner box or damage the cooling system, which will lead to freon leakage.
The main goal is to allow the ice to turn into water without mechanical and thermal damage to the internal components. If the layer of ice is very thick, it is better to be patient and wait than to risk the integrity of evaporator.
Sanitizing and eliminating odors
The defrosting period is the ideal time not only to remove ice, but also to perform a general cleaning of the refrigerator. During operation, bacteria, mold and unpleasant odors can accumulate inside the chambers, which negatively affect the quality of stored products. After all the ice has melted and the water has been removed, it is necessary to thoroughly wipe all surfaces. sanitary treatment refrigerator. During operation, bacteria, mold and unpleasant odors can accumulate inside the chambers, which negatively affect the quality of stored products. After all the ice has melted and the water has been removed, all surfaces must be thoroughly wiped down.
To wash the interior, it is best to use a solution of baking soda (1 tablespoon per liter of water) or a weak solution of vinegar. These products effectively remove dirt and neutralize odors without leaving behind harmful chemicals. Avoid using abrasive powders and chlorine-containing products, which can damage the coating of the chambers and leave a persistent chemical odor.
Pay special attention to the rubber seals on the doors. Dirt and mold often accumulate in their folds, which disrupts the tightness of the door. Wipe the elastic bands with a cotton pad soaked in soda solution and check their elasticity. If the seal is damaged or out of shape, it must be replaced, otherwise the cold will escape and the refrigerator will work with overload.
| Cleaning agent | Efficiency | Safety | Recommendation |
|---|---|---|---|
| Soda solution | High | Absolute | Ideal for regular processing |
| Vinegar water | Medium | High | Removes odors well |
| Special means | High | Depends on the composition | Requires careful flushing |
| Chlorine-containing | High | Low | Not recommended for food-grade plastic |
Starting the Biryusa refrigerator after defrosting
After After completing all cleaning procedures and removing moisture, the unit must be started correctly. Make sure that all removable parts (shelves, drawers) are completely dry and in place. Refrigerator doors must be tightly closed. Only after this can you turn on the device to the electrical network.
Do not immediately load the refrigerator with food. Let it idle for 2-4 hours to reach the required operating temperature. In models Biryusa with a mechanical thermostat, it is better to initially set the control knob to the middle position. This will allow the compressor to enter the operating rhythm without excessive load.
If after turning on you hear an unusual noise or notice that the refrigerator is not cooling, let it stand for some more time. Sometimes the system takes up to 12 hours to completely stabilize pressure and temperature, especially if defrosting was carried out in winter or in a cold room. Check the operation of the thermostat by placing a thermometer inside.
Frequency of defrosting and ice prevention
The frequency of the defrosting procedure depends on the model of your refrigerator and its operating conditions. For classic models Biryusa with manual defrosting of the freezer compartment and a drip system in the refrigerator compartment, it is recommended to carry out the procedure every 4-6 months or as an ice crust of 5-7 mm thick forms.
To minimize the formation of ice and increase the intervals between defrosts, keep an eye on door tightness. Do not leave the door open longer than necessary. Also, do not place hot or warm products in the chamber - they emit a lot of steam, which instantly condenses and freezes on the walls.
Regular checking of the condition of the seals and timely replacement of worn parts will also help reduce the load on the cooling system. If you notice that ice has begun to accumulate faster than usual, this may indicate a malfunction of the thermostat or problems with the water drainage system, which requires the attention of a specialist.
⚠️ Attention: If an ice “coat” forms too quickly (within 1-2 weeks), this is a sign of a malfunction. Check the tightness of the door or contact a service center to diagnose the thermostat.
What will happen if you do not defrost at all?
Ignoring defrosting leads to the fouling of the evaporator with a thick layer of ice, which blocks heat transfer. The compressor begins to work continuously, trying to compensate for the loss of cold, which leads to its overheating, increased energy consumption and eventual failure. In addition, the useful volume of the chambers is narrowed.
Frequently asked questions (FAQ)
Do you need to remove food when defrosting the Biryusa refrigerator?
Yes, the food must be removed completely. Food left inside will impede air circulation, slow down the melting of ice, and may spoil due to the increase in temperature in the chamber during the long defrosting process.
How long does defrosting take on average?
The time depends on the thickness of the ice and the temperature in the room. Typically the process takes from 3 to 8 hours. In rare cases, with a very thick layer of ice, it may take up to 24 hours for the chambers to dry completely.
Is it possible to defrost the Biryusa refrigerator in winter on the balcony?
It is not recommended to take the refrigerator out into the cold to defrost. Sudden temperature changes can damage internal materials. In addition, the operating instructions prohibit storing and operating the device at temperatures below +5°C (or +10°C for some models), since the oil in the compressor thickens.
Why does the refrigerator not turn on for a long time after defrosting?
This is normal for some models. The thermostat takes time to register the increase in temperature inside the chamber after you close the doors. If the refrigerator does not turn on for more than 12 hours, check the thermostat settings.
Is frequent defrosting dangerous for equipment?
Defrosting itself is not dangerous if it is carried out correctly (naturally). However, unnecessarily defrosting too frequently (for example, every week) creates unnecessary heating-cooling cycles for the materials. It is optimal to do this as ice forms.
