The appearance of cracks in the plastic or deformation of the body of the freezer compartment is not just a cosmetic defect, but a serious threat to the entire device. Owners of brand household appliances Biryusa often face the need to completely replace this unit, since repairing chips or holes at home rarely gives a durable result. Violation of the tightness leads to refrigerant leakage and compressor failure, which makes replacement freezer compartment a critical procedure for extending the life of the unit.
This process requires not only physical strength, but also strictly follow the sequence of actions so as not to damage the cooling system. Replacing an internal tank involves working with fragile structural elements, thermal insulation and a complex fastening system. It is important to understand that even when purchasing original spare parts, there may be installation nuances that must be taken into account in advance. In this article, we will analyze in detail all stages of work, from the selection of components to the final leak test.
Before starting disassembly, make sure that you have the necessary set of tools and free space for work. Biryusa refrigerator - the equipment is reliable, but its internal layout may vary depending on the year of manufacture and the specific series. Incorrect actions can lead to damage to the evaporator or damage to the thermal insulation, so carefully read the instructions provided.
Diagnostics and selection of replacement components
The first step is to accurately determine the model of your refrigerator, since freezers cameras Biryusa are not universal. The shape, dimensions, arrangement of shelves and, most importantly, the configuration of the evaporator (weeping or hidden type) can differ radically. An attempt to install a tank that is not suitable in size or design will lead to a loose fit of the seals and a violation of the temperature regime.
When searching for a spare part, pay attention not only to the appearance, but also to technical characteristics. The plastic from which the chamber is made must be frost-resistant and withstand defrosting cycles without the appearance of microcracks. Cheap analogues are often made from recycled materials, which become brittle at low temperatures.
- 🔍 The exact article number of the refrigerator model, indicated on the nameplate inside the case.
- 📏 Overall dimensions of the internal perimeter of the freezer compartment.
- ❄️ Type of defrosting system (manual or No Frost), which affects the design of the back wall.
- 🔩 Availability and location of mounting holes for fixing to the refrigerator body.
⚠️ Attention: When ordering spare parts from the photo, always check with the seller for compatibility with yours series Biryusa. Visual similarity does not guarantee the matching of the seats for the evaporator and the fasteners.
If you change the camera due to mechanical damage, be sure to check the condition of the camera itself evaporator. Often, an impact that pierces the plastic also damages the heat exchanger tubes. In this case, simply replacing the plastic will not solve the problem - a more complex repair will be required with refilling the system.
Necessary tools and workplace preparation
High-quality replacement of the freezer compartment is impossible without the right tools. You will need not only a standard set of screwdrivers, but also specialized tools for working with plastic and refrigerants. Preparation of the workplace also plays a key role: the refrigerator must be stable, and there must be enough space around it to maneuver.
Pay special attention to lighting. Refrigerator interiors are often dark, and poor light can cause you to miss an important fastener or damage wiring. Using a headlamp will greatly simplify the task and reduce the risk of mistakes.
☑️ Tools for replacement
Before starting work, the refrigerator must be completely defrosted and disconnected from the power supply. This mandatory safety requirementignoring may result in electric shock or damage to the compressor. All shelves, drawers and removable elements must be removed from the chamber.
Prepare a container in advance to collect possible moisture that will remain in the drainage system after defrosting. It is also recommended to cover the floor around the refrigerator with thick fabric or cardboard so as not to damage the floor covering with the sharp edges of the dismantled parts.
Removing the old freezer
The process of removing the old camera begins with dismantling all visible fasteners. In refrigerators Turk access to them is often closed with decorative plugs or plastic panels. Be careful not to break the plastic clips, which become brittle over time.
First remove the freezer door, if the design of your model allows this. This will greatly facilitate access to the internal fasteners and allow you to remove the camera without the risk of damaging the sealing rubber. Removing the door may require the help of a second person due to its weight and dimensions.
| Dismantling stage | Action | Important detail |
|---|---|---|
| 1. Preparation | Disconnection from the network, defrosting | Drain the water from the drain |
| 2. Removing the door | Unscrewing the hinges | Secure the door when removing |
| 3. Removing shelves | Removing all drawers | Check for hidden screws |
| 4. Detaching | Separating the chamber from the body | Do not pull the evaporator tubes |
When removing the old chamber, it may be necessary to apply force, since over the years of operation the thermal insulation could “stick” to the metal of the case. Do not use sharp metal objects to pry, so as not to damage the external contour of the refrigerator. It is better to carefully heat the joints with a hair dryer at a minimum temperature.
⚠️ Attention: It is strictly forbidden to pull the camera by the evaporator tubes or sensor wires. This will lead to depressurization of the circuit and costly repairs.
After removing the old camera, carefully inspect the vacated niche. There may be remnants of old insulation, pieces of foam or debris that must be carefully removed. The surface must be clean and dry before installing a new element.
Installing and sealing a new freezer
Installing a new freezer is a process that requires pinpoint precision. The new tank Biryusa should fit into place the first time, without distortion. If you feel resistance, do not use force - check if the wires or structural elements of the case are in the way.
The key point is to ensure the tightness of the joints between the new chamber and the refrigerator body. Even microscopic gaps will lead to the formation of condensation, which, when frozen, will rupture the insulation and reduce the efficiency of the unit. To seal, use special compounds that are resistant to low temperatures.
What is the best way to seal joints?
To seal freezers, it is best to use a special two-component adhesive-sealant for refrigerators or polyurethane foam with a low coefficient of expansion. Ordinary silicone may not withstand temperature changes and will peel off over time, damaging the thermal insulation.
When fixing the camera, make sure that all mounting screws are tightened evenly. Over-tightening can lead to deformation of the plastic and the appearance of cracks in the future, and under-tightening can lead to vibration and noise during compressor operation. Use a torque wrench if possible, or use the torque recommended by the manufacturer.
After installation and fixation, allow the sealant or foam to dry completely. Curing time depends on the type of material used and usually ranges from 12 to 24 hours. Starting the refrigerator early can disrupt the hardening process and lead to displacement of the chamber.
Assembling and connecting the cooling system
If the chamber was replaced along with the evaporator, the next step is connecting the tubes and sensors. This is the most technical part of the job and requires skills in working with copper piping and refrigerants. At home, without special equipment (vacuum pump, pressure gauge station), it is almost impossible to perform this stage efficiently.
When connecting electrical temperature and defrosting sensors, it is important to observe the polarity and reliability of the contacts. Oxidized or poorly connected contacts will lead to incorrect operation of the thermostat, which can cause either undercooling of the products or continuous operation of the compressor.
- 🔌 Check the integrity of the wire insulation before connecting.
- 🌡️ Make sure that the temperature sensor fits snugly against the chamber wall.
- 🔩 Fix the evaporator tubes in their normal places so that they do not vibrate.
- 💨 When filling with refrigerant, strictly follow the dosage indicated on the nameplate.
After assembling all components and connecting the electrical system, the system is evacuated. This is necessary to remove moisture and air, which, if present in the circuit, will cause blockage of the capillary system and corrosion of the internal parts of the compressor. The duration of evacuation depends on the power of the pump and the volume of the system.
Filling with refrigerant is carried out strictly by weight. The use of cylinders without scales is unacceptable, since excess or lack of freon critically affects the performance of the refrigerator Biryusa. After refueling, the connections are checked for leaks using a soap solution or a leak detector.
First launch and performance check
The final stage is a test run. You can turn on the refrigerator only after all used sealants have completely dried and the filling procedure has been completed. The first cycle of operation should be supervised in order to notice possible malfunctions in time.
Pay attention to the sound of the compressor running. Extraneous knocking, hissing or excessive hum may indicate problems with the installation of tubes or the quality of the work performed. Normal operation is characterized by a smooth, quiet hum.
⚠️ Attention: Do not load the refrigerator with food immediately after turning it on. Let it run idle for 2-3 hours to stabilize the temperature and check the tightness.
Check the operation of the defrost system (if it is automatic). After several cycles of operation, there should be no excess ice on the back wall or, conversely, a complete absence of frost where it should be. Uniform distribution of cold is a sign of a properly installed and configured freezer.
If no anomalies are detected during the first day of operation, the refrigerator can be considered successfully repaired. Regularly check the condition of the seal of the new chamber in the first weeks of operation, as the plastic may “shrink” a little.
Is it possible to replace the freezer yourself without calling a technician?
Theoretically, replacing a plastic tank is possible with your own hands, if you do not need to re-weld the tubes and refill with freon. However, if the evaporator is damaged, independent repair without special equipment and skills is impossible and dangerous.
Where can I find the original freezer for the Biryusa refrigerator?
Original spare parts are best ordered from the manufacturer’s authorized service centers or from official dealers. There are many analogues on the market, the quality of which may be significantly inferior to the original.
How long does it take to replace the freezer compartment?
If you have all the tools and spare parts, the mechanical replacement process takes from 2 to 4 hours. If refrigerant charging and evacuation are required, the time can increase to 6-8 hours, taking into account technological breaks.
What to do if the new chamber does not fit into place?
Do not use force. Check the markings of the spare part - it may be intended for a different model. Also make sure that the remnants of old insulation and fasteners that interfere with installation are completely removed.
