Operation of household appliances requires compliance with certain rules, and refrigerator Biryusa 125 is no exception. Despite the reliability of the Soviet and Russian assembly, this model belongs to the class of devices with a manual or semi-automatic defrosting system, which requires periodic user intervention. Ignoring the need to remove the ice crust can lead to a decrease in the efficiency of the compressor and spoilage of products.
Many owners wonder about the frequency of this procedure, since the instructions do not always indicate specific time intervals. Ice on the evaporator formed due to the moisture contained in air that enters the chamber when the doors are opened. Over time, this ice turns into a thick layer of snow, which isolates the cooling tubes from the internal space, forcing the motor to wear out.
The process of removing ice does not require special technical skills, however, it is important to follow the sequence of actions to maintain the integrity of the unit. A critical point is to prohibit the use of sharp objects to chip iceas damage to the tubes evaporator with freon will lead to expensive repairs, which are often not economically feasible. In this article, we will analyze in detail the algorithm of actions that will help you safely and quickly put your equipment in order.
Determining the need for defrosting
The first step is to understand exactly when your device needs a “rest.” Unlike modern systems No Frost, classic models require user attention. The signal to begin the procedure is the appearance of a visible snow coat on the back wall of the freezer. If you notice that the layer of frost has become dense and occupies a significant part of the volume, you need to act immediately.
Another sign is a change in the operating mode of the compressor. When heat exchange is disrupted by the ice crust, temperature sensors detect insufficient cooling and force the motor to work almost without interruption. This leads to increased energy consumption and heating of the outside of the case. Ice thickness more than 5-7 millimeters is already considered critical for effective operation.
It is also worth paying attention to the condition of the products. If you notice that food in the freezer has become less freezing or, conversely, is drying out due to the constant blowing of a running fan (in models with circulation), this is a sure sign of a heat transfer problem. Regularly checking the condition of the evaporator will help to avoid emergency situations.
- ❄️ The appearance of a noticeable layer of snow on the back wall of the freezer.
- 🔊 The compressor works continuously, without the usual pauses.
- 💧 The presence of puddles under the refrigerator due to overflow of the drainage gutters.
- 📉 Deterioration in the quality of freezing food at standard settings.
Preparatory stage before defrosting
Before taking active steps, it is necessary to properly prepare the unit and the surrounding area. You should start by emptying the chambers of food. It is better to transfer all perishable products to a cool place or use thermal containers with ice if it is hot outside. Refrigerator Biryusa 125 has quite spacious shelves, but even a couple of kilograms of food can significantly slow down the thawing process.
Next you need to turn it off device from the mains. Unplug the cord from the outlet to eliminate any risk of electric shock or short circuit as the water melts. If the cord is short, make sure it will not lie in water that will start to drip onto the floor. Safety is the top priority in this case.
Free up the interior space completely: remove all shelves, drawers, egg trays and containers. It is better to wash plastic and glass elements separately in warm water and a mild detergent while they dry. This is the ideal time for general cleaning inside the cells, while access to the corners is open.
☑️ Preparation checklist
⚠️ Attention: Never try to wash the internal surfaces or defrost the unit while it is plugged in. Water is a conductor of electricity, and moisture on electrical contacts can damage the control board or compressor.
Natural defrosting and speeding up the process
The safest way to remove ice is to let it melt on its own at room temperature. This method takes longer, but guarantees the safety of the internal coatings and evaporator tubes. Just leave the refrigerator doors open. Depending on the thickness of the ice crust and the temperature in the room, the process can take from 3 to 8 hours.
If time is running out, you can use proven acceleration methods. For example, place containers with hot water inside the chambers (but not boiling water, so as not to damage the plastic). Close the doors for 15-20 minutes, then repeat the procedure. Warm steam effectively softens the ice. You can also use a hair dryer, but with great caution: direct the stream of warm, not hot air, and do not bring the device too close to the plastic.
Some users try to chip the ice with a knife or screwdriver. Strictly prohibited use metal and sharp objects. The aluminum evaporator, which is often installed in models like Biryusa, has very thin walls. One awkward movement will lead to a puncture, leakage of freon and moisture entering the system, which actually means the end of the life of the refrigerator.
Is it possible to use salt to speed up?
Salt does reduce the melting point of ice, but use it inside the refrigerator is not recommended. The salt solution can corrode metal parts and damage rubber seals, as well as leave stubborn stains on plastic.
During the melting process, watch where the water flows. Models with manual defrosting often do not have a water drainage system into a special tray on the compressor, so moisture will drain onto the floor. Prepare absorbent rags and basins in advance.
Removing water and cleaning the drainage system
When the main body of ice melts, it is necessary to collect the resulting water. Use a soft cloth or sponge to wipe the sides and bottom of the chambers dry. Pay special attention to the recesses and joints where moisture can stagnate, creating a favorable environment for the growth of bacteria and the appearance of mold.
An important step is to clean the drainage hole, if it is provided by the design for draining water from the refrigeration chamber (in the Biryusa 125 freezer there is usually no such hole, water drips straight down). A clogged drain is a common cause of puddles appearing under the refrigerator while it is running. For cleaning, you can use a special brush or soft wire wrapped in a cloth.
After removing water and ice, thoroughly wipe all surfaces with a dry cloth. Residual moisture can quickly turn into a new layer of frost immediately after switching on, so the drying step cannot be ignored. Make sure that the rubber seals on the doors are also clean and dry.
| Defrost method | Execution time | Safety | Efficiency |
|---|---|---|---|
| Natural melting | 4-8 hours | High | Medium |
| Containers with warm water | 1-2 hours | High | High |
| Hair dryer (warm air) | 30-60 minutes | Medium (risk of overheating) | Very high |
| Mechanical chipping | 15-30 minutes | Low (risk of puncture) | High |
Care for seals and external elements
While the refrigerator is defrosted and open, it’s time to take care of the condition of the sealing rubber. It is its elasticity that determines how tightly the door fits to the body. If the seal is dirty, grease and dirt get into it, which over time leads to loss of tightness. Wipe the elastic with warm water and soapy water, removing all dirt from the folds.
Check the integrity of the seal. If you find cracks, tears or areas where the rubber is “oaky” and does not fit, it must be replaced. A loose door seal is the main reason for rapid ice buildup in the future. Cold air will leave, and warm, moist air from the room will flow in, condense and freeze.
Don't forget to wipe the outer surfaces of the case. Dust on the rear grille (condenser) reduces heat transfer efficiency, causing the compressor to work harder. Carefully walk with a vacuum cleaner or dry brush along the back wall, removing dust “felt boots”.
- 🧼 Wipe the seals with soft products without chlorine and aggressive solvents.
- 🔍 Check the magnetic properties along the entire length of the door.
- 🚿 Wash removable shelves with water at a comfortable temperature so that the glass does not burst due to changes.
- 🌬️ Ensure ventilation of the back wall after installation in place.
⚠️ Attention: To lubricate the rubbing parts of the seal or restore elasticity, use only special silicone-based products or regular glycerin. Vegetable oil or Vaseline can corrode the rubber over time.
Starting the refrigerator after defrosting
After all cleaning and drying procedures have been completed, you can assemble the unit. Replace all shelves, drawers and containers. Make sure they fit correctly and there is nothing preventing the doors from closing. Now you can turn on the refrigerator.
However, do not rush to load food right away. Empty refrigerator it takes time to reach operating temperature. Typically this process takes from 1.5 to 3 hours. During this time, the compressor will work intensively. Load products only after the necessary cold has established inside.
It is better to do the first load in small portions, without overloading the chamber with a large number of warm products at once. This will help the system quickly return to normal operation. If your model has a power regulator, in the first hours after turning it on, you can set it to maximum, and then return it to normal mode.
Frequent errors during maintenance
Owners often make mistakes that negate all care efforts. One of the most common is turning on the refrigerator immediately after defrosting, without waiting for the internal surfaces to completely dry. The residual moisture will instantly turn into ice, and after a couple of days you will see a snow coat again.
Another mistake is using aggressive chemicals for washing. Abrasive powders scratch the plastic, and dirt gets clogged into these microcracks, which then cannot be washed out. In addition, the smell of chemicals can be absorbed into the food. Use only specialized products or a baking soda solution.
It is also a mistake to ignore regularity. You cannot wait until the ice completely blocks the door or the drawer stops closing. Regular maintenance extends the service life Biryusa 125 for many years.
How often should Biryusa 125 be defrosted?
The recommended defrosting frequency depends on the operating conditions. On average, the procedure should be performed 1-2 times a year. If you open doors frequently or there is high humidity in the room, defrosting may be required every 3-4 months. Focus on the thickness of the ice: reached 5 mm - defrost.
What to do if after defrosting the refrigerator does not freeze?
If after turning on and running for several hours the cold does not appear, perhaps something more serious has happened in the system than just ice. This could be a freon leak (if you accidentally damaged the tube), a broken thermostat or start relay. In such cases, you need to call a specialist.
Is it possible to defrost a refrigerator without unplugging it?
No, it is not possible. Defrosting involves turning off the power. There is no point in leaving the refrigerator on with the doors open - the compressor will run idle, trying to cool the room, and will quickly burn out. In addition, this is unsafe due to the risk of water getting into the electrical components.
Why did an unpleasant odor appear after defrosting?
An unpleasant odor after defrosting usually indicates that there are contaminants left inside that have not been removed, or stagnant water with bacteria has accumulated in the drainage system. Thoroughly rinse all surfaces with a solution of soda or citric acid and leave the refrigerator open for ventilation.
