Owners domestically produced refrigeration equipment is often faced with the need for manual maintenance of the unit, especially when it comes to classic models with a drip system or static cooling. The model Biryusa 151 belongs to the category of reliable two-chamber refrigerators, which, despite their durability, require periodic user intervention to maintain efficient operation of the compressor and maintain the quality of the products. Ignoring the formation of an ice crust can lead to an increase in energy consumption and a reduction in the service life of equipment.
The ice removal process does not require special technical skills, but it does imply strict adherence to the sequence of actions so as not to damage the internal elements of the structure. In this article, we will look in detail at how often the procedure needs to be carried out, what tools will be needed, and how to avoid common mistakes that inexperienced users make when servicing household appliances.
It is worth noting that timely maintenance allows you to maintain optimal temperature conditions in the chambers. If you notice that ice thickness on the back wall or shelves has exceeded several millimeters, this is the first signal to action. Next, we will look at an algorithm of actions that will help you quickly and safely put the refrigerator in order.
Frequency of defrosting and signs of the need for the procedure
It is difficult to determine the exact date when you need to turn off the refrigerator without reference to specific operating conditions. The frequency of ice formation is affected by the humidity in the room, the number of door openings and the tightness of the seals. For the model Biryusa 151 manufacturers and service center technicians recommend complete defrosting at least once every 4-6 months.
However, there are external signs that dictate their conditions and require earlier intervention. If you notice that the refrigerator is starting to run louder than usual or the compressor cycles more frequently, the heat transfer may be impaired due to the insulation layer. Also, the need for urgent cleaning is indicated by a decrease in the useful volume of the chambers.
Pay attention to the following symptoms that require immediate defrosting:
- 🧊 Ice crust on the back wall of the refrigerator compartment is thicker than 5 mm.
- ❄️ Snow coat completely (covered) evaporator in the freezer compartment.
- 💧 Water began to accumulate on the floor under the refrigerator or in the lower vegetable drawer faster than usual.
- 🌡️ Food in the refrigerator compartment stopped cooling to the desired temperature, despite the standard settings.
⚠️ Attention: If ice has formed unevenly or only in one corner of the chamber, this may not indicate the need for scheduled defrosting, but a malfunction of the water drainage system or damage to the sealing rubber.
Regularity of maintenance directly affects energy efficiency devices. The layer of ice acts as a heat insulator, forcing the compressor to work harder to compensate for the loss of cold. Therefore, visual monitoring of the condition of the chambers should become a habit for every owner.
Preparatory stage before turning off the power
Before pressing the power button or unplugging the cord from the outlet, you must perform a number of preparatory steps. This will minimize the risk of food spoilage and simplify subsequent cleaning. First of all, it is recommended to empty the cells of food supplies.
If it is winter outside, the food can be temporarily taken out to the balcony, having previously packed it. During the warm season, use thermal bags, cooler bags, or transfer perishable goods to a nearby unit. It is important not to leave food at room temperature for a long time.
Next, you should prepare your work area:
- 🧹 Cover the floor around the refrigerator with absorbent rags or towels, since when the ice melts, water can flow out of the tray.
- 🪣 Prepare a shallow basin or a ladle for collecting the bulk of the melting water, if the design does not provide for convenient drainage.
- 🧽 Find a soft sponge and detergent in advance to combine defrosting with sanitary treatment.
Do not forget to remove all removable elements: shelves, drawers, egg trays and containers on the door. It is better to wash them separately in the bathroom or sink with warm water and detergent. This will provide access to all internal surfaces and corners of the chamber.
Only after the refrigerator is empty of contents and accessories can you proceed to turn off the power supply. Unplug the cord from the outlet or turn the thermostat to the "0" or "Off" position. The model Biryusa 151 is characterized by the presence of a mechanical regulator, which is usually located inside the chamber or on the body.
☑️ Preparation for defrosting
Safe removal technology ice
The most important principle when defrosting a refrigerator Biryusa 151 is the natural melting of ice. Many users try to speed up the process by using a hairdryer, hot water or sharp objects, which is strictly prohibited by the instructions. Such actions can lead to irreversible damage.
Leave the refrigerator and freezer doors open. Circulating warm air from the room will start the melting process. Depending on the thickness of the ice layer and the temperature in the room, this may take from 3 to 6 hours. Don't rush things.
It is strictly forbidden to use the following acceleration methods:
- 🔥 Breaking off the ice with a knife, screwdriver or other sharp tool - there is a high risk of breaking the pipes evaporator, which will lead to freon leakage and expensive repairs.
- 💨 Blowing hot air on the ice - a sudden temperature change can cause cracking of the plastic or damage to the seals.
- 🌡️ Pouring boiling water on the walls of the chambers - this can deform the internal plastic and damage electronic components if they are located close to walls.
⚠️ Attention: Damage to the cooling system by sharp objects is not covered by warranty. Repairs after such intervention are often not economically feasible.
If the pieces of ice are large and in the way, you can carefully pry them off with a plastic scraper, which is sometimes included, or a regular plastic spatula. The main thing is not to make excessive efforts. To speed up the process, you can place bowls of warm (not hot) water inside the chambers, covered with a towel, so that the heat is transferred more smoothly.
What to do with a large amount of water?
If there was a lot of ice, the water may overflow the tray. Monitor the level of liquid in the collection container and pour it out promptly. Do not allow water to flow into the technical holes at the bottom of the chamber.
Washing and disinfection of internal surfaces
While the ice is melting or after it is completely removed, the hygiene stage begins. Bacteria, mold and unpleasant odors may have accumulated inside the refrigerator during operation. The model has plastic internal panels that are easy to clean. Biryusa 151 To clean, use a weak solution of baking soda, vinegar or a special refrigerator cleaner. Avoid using abrasive powders, hard brushes and aggressive chemicals containing chlorine or acids, as they can damage the coating and leave scratches in which microbes will multiply. Biryusa 151 has plastic interior panels that are easy to clean.
To clean, use a weak solution of baking soda, vinegar, or a special refrigerator cleaner. Avoid using abrasive powders, hard brushes and harsh chemicals containing chlorine or acids, as they can damage the finish and leave scratches in which germs can grow.
Pay special attention to hard-to-reach places:
- 🚿 Corners of chambers and joints between panels.
- 🚿 Grooves for water drainage (drainage holes).
- 🚿 Rubber seals on the doors (they need to be wiped carefully without stretching).
- 🚿 Grilles on the back wall, if they are removable.
After When cleaning wet, be sure to wipe all surfaces dry with a clean rag. Residual moisture can quickly turn into a new layer of ice immediately after turning on the compressor. Also, do not forget to rinse and dry all removed shelves and drawers before installing them back.
Comparison of defrosting methods: table
There are several approaches to servicing refrigeration equipment, but not everyone is suitable for the model Biryusa 151 . Below is a comparison of different methods so that you can choose the safest and most effective option.
| Method | Safety | Speed | Risk damage |
|---|---|---|---|
| Natural melting | High | Low (3-6 hours) | Absent |
| Use of a hair dryer | Low | High | High (plastic, seals) |
| Mechanical cleaning | Critical | Average | Critical (circuit breakdown) |
| Warm water in containers | Average | Average | Low (at accuracy) |
As can be seen from the table, natural melting remains the only completely safe method. Although it takes more time, it guarantees the safety of all components and assemblies of your refrigerator. Attempts to save time can lead to costs that are many times higher than the cost of electricity during downtime.
After completing all deicing and washing procedures, leave the doors open for another 15-20 minutes for final ventilation and evaporation of residual moisture. Make sure that the drainage hole is free and the water flows out by gravity.
Starting the refrigerator after defrosting
The final stage is to turn on the unit correctly. Do not rush to load food immediately after plugging the cord into the outlet. The compressor and refrigerant need time to reach operating mode and stabilize the temperature inside the chambers.
Close the doors and turn on the refrigerator. Let it run idle for at least 2-3 hours. During this time, the temperature will drop to the set values. Only after this can you gradually load the products. A sudden load with warm products will cause the motor to work with overload.
Monitor the operation of the device in the first hours:
- 🔊 Make sure that the compressor turns on and runs smoothly, without extraneous knocks.
- ❄️ Check whether the air begins to cool in chambers.
- 💧 Make sure that water does not flow out through the drainage.
⚠️ Attention: Specifications and maintenance requirements may vary slightly depending on the year of manufacture of your model. Always check the official instructions that come with your specific device.
Following these simple rules will allow your refrigerator Biryusa 151 to serve for many years without breakdowns. Regular care is the key to freshness of food and saving the family budget.
Frequently asked questions (FAQ)
Is it possible to defrost only the freezer chamber, leaving the refrigeration chamber running?
In models like Biryusa 151 with one compressor and a common refrigerant circulation system, defrosting only one chamber, turning off the other, is technically impossible without complex modernization. When the power is turned off, the heat is distributed throughout the entire volume, so the entire unit is defrosted.
What to do if after defrosting the refrigerator does not freeze?
If more than 5-6 hours have passed after turning it on and no cold has appeared, the circuit may have been damaged during cleaning or a displacement has occurred refrigerant. The cause may also be a malfunction of the thermostat or start relay. In this case, you need to call a specialist.
How often should you clean the drainage hole?
It is recommended to clean the drainage hole every time it is completely defrosted. To do this, you can use a special brush or soft wire, carefully removing accumulated dirt and mold so that the water flows freely into the evaporator.
Is frequent switching on and off during defrosting dangerous for the compressor?
The defrosting process itself is not harmful. However, if you defrost the refrigerator too often (for example, once a week) without a clear need, it creates unnecessary thermal stress cycles on the materials. Follow the recommended schedule once every six months.
