Brand refrigerators Biryusa have remained popular for decades due to their reliability and affordability, but even the highest quality equipment requires periodic maintenance or repair. Owners are often faced with the need to deep clean the freezer compartment, replace sealing rubber or troubleshoot problems in the water drainage system, which cannot be done without partially disassembling the unit.
Independent dismantling of internal components requires caution, since the design of the evaporator and plastic elements has its own characteristics depending on the model and year of manufacture. Incorrect actions can lead to damage to fragile fasteners or, worse, to depressurization of the cooling circuit, so it is important to strictly follow the algorithm of actions.
In this article we will take a detailed look at the process of disassembling the freezer, paying special attention to hidden fasteners and the nuances of working with plastic parts, which often become an obstacle for inexperienced craftsmen.
Worker preparation places and necessary tools
Before starting any work on servicing refrigeration equipment, it is necessary to ensure safety and prepare all the required tools so that there are no hiccups in the process. Disconnection from electrical network is a mandatory first step that cannot be ignored, since working with electrical wiring or wet live components is deadly.
You will need a set of screwdrivers of various configurations, including Phillips and flathead, as well as a special knife for plastic or a spatula to carefully pry off the latches without the risk of damaging the case. It would also be a good idea to prepare a container for collecting water if defrosting is planned, and a soft rag for wiping parts.
⚠️ Attention: Before starting work, be sure to wait until the ice, if any, is completely defrosted. Attempts to chip the ice or forcibly tear off frozen parts will lead to breakdown of the evaporator and leakage of freon.
For ease of operation, it is recommended to clear the space around the refrigerator in advance, ensuring access from all sides, since some models require tilting or moving to access the rear of the unit. If you plan to replace the seal, make sure that the new repair kit fully matches the modification of your Biryusa.
☑️ Preparation for disassembly
Dismantling of shelves, drawers and attachments
Disassembly should begin by freeing the internal volume freezer compartment from all removable elements, including shelves, containers and baskets. In most models Turk shelves are fixed on guides or special stops that need to be carefully lifted or moved to the side to remove glass or plastic elements.
Freezing boxes often have a locking system that prevents them from accidentally falling out when the door is opened, so they need to be removed slightly lifting the front part and pulling it towards you. If the drawer is stuck due to frozen ice, do not use force - it is better to wait until the ice melts, or use a hair dryer at minimum power, directing warm air to the gaps, but not to the plastic.
After removing the main contents, pay attention to the freezer door: if you need to remove the shelves from the door, it is usually enough to simply pull them up or unclip the side latches. In some modifications, the door shelves are secured with screws hidden under decorative plugs, which need to be carefully pryed off with a thin tool.
Removing the internal plastic lining
Plastic The lining of the inner chamber serves not only as a decorative element, but also hides thermal insulation and fastening units, so its dismantling requires special care. Fastening plastic in refrigerators Biryusa is usually done using self-tapping screws and plastic latches, which can become brittle over time.
Carefully inspect the perimeter of the freezer: screws are often hidden under rubber plugs or in recesses that are not obvious. After unscrewing all visible fasteners, you must carefully press the latches around the perimeter of the panel, using a plastic spatula, so as not to leave scratches or chips.
You should act sequentially, starting from one of the corners, and gradually move along the sides, controlling the force, so as not to break the mating parts of the latches on the body of the refrigerator. If the panel cannot be removed, do not pull it sharply - check to see if any hidden screw is left unscrewed or if the wiring is in the way.
⚠️ Attention: Plastic becomes very brittle at low temperatures. If the refrigerator has just defrosted, let it sit at room temperature for 15-20 minutes before removing the panels.
When removing the lining, you may encounter wires going to the temperature sensors or the light bulb, if they are located inside the chamber. In this case, you need to carefully disconnect the connectors, having first remembered or photographed their position, so as not to mix up the contacts during assembly.
Access to the evaporator and defrosting system
After removing the plastic lining, you will have access to the main working element of the freezer - the evaporator, which is a coil with ribs or a plate design. This is where the air is cooled, and this is where ice most often accumulates when the defrost system malfunctions.
The evaporator in models Biryusa can be attached to the back wall of the chamber using screws or special brackets that must be carefully removed. When working in close proximity to the evaporator tubes, it is extremely important to be careful, since even a microscopic puncture of the aluminum tube will lead to the release of refrigerant and expensive repairs.
If the purpose of disassembly is to check or replace the defrost heating element, defrost sensor or timer, then these elements are usually located in the lower or upper part of the evaporator, often hidden by an additional casing. To access them, you will need to remove the protective screen, which can be attached to clips or screws.
Why can’t you clean off the ice with a knife?
Aluminum evaporator tubes have very thin walls. One careless movement with a sharp object will lead to instant depressurization of the circuit, hissing of gas and the need to call a technician for refilling and soldering.
When inspecting the defrost system, pay attention to the condition of the drainage hole through which water leaves. It often becomes clogged with dirt or ice, which requires cleaning with a soft wire or rinsing with warm water using a syringe.
Features of disassembling the freezer door
The refrigerator door Biryusa is a complex assembly consisting of an external and internal frame, insulation and seal, and its complete disassembly is rarely required, usually to replace the sealing rubber or hinge. Removing the door from the body is done by unscrewing the hinges, but to replace the seal, complete dismantling of the door is not always necessary.
The sealing rubber in most models is held in a special groove around the perimeter of the door and is additionally fixed with screws in the corners or along the contour. To remove the old seal, you need to unscrew the fixing screws and carefully pull the edge of the rubber out of the groove, gradually freeing the entire perimeter.
When installing a new seal, it is important to position it correctly in the groove so that folds do not form that will disrupt the tight fit. After installation, it is recommended to warm the rubber with a hairdryer or allow it to straighten naturally so that it takes the desired shape.
If you need to remove the door panel itself (for example, to replace the internal plastic), then a decorative frame or screws hidden under plugs run along the perimeter of the inside of the door. After removing them, the inner plastic panel separates from the metal body of the door, providing access to the insulation.
Typical errors during disassembly and fault table
Disassembly process refrigerator Biryusa seems simple only at first glance, but inexperienced craftsmen often make mistakes that complicate subsequent assembly or lead to breakdowns. One of the most common mistakes is the use of excessive force where the latch mechanism should work, which leads to breakage of the plastic ears of the fasteners.
The markings of the removed screws are also often ignored: the refrigerator uses fasteners of different lengths and threads, and installing a long screw in a short hole can lead to penetration of the insulation or damage inner wall.
The following table helps to associate the symptoms of a malfunction with the unit requiring access:
| Symptom | Probable cause | Required access |
|---|---|---|
| Increasing "coat" of ice | Malfunction of the defrost heating element or sensor | Removing the rear panel of the freezer |
| Water on the kitchen floor | Clogged drainage hole | Access to the bottom of the evaporator |
| The refrigerator does not freeze | Freon leak or compressor failure | Access to the back wall (behind the refrigerator) |
| The door is not fits | Wear of the seal or misalignment of the hinges | Dismantling the door or seal |
Another critical mistake is ignoring the condition of the wiring: when reassembling, it is important to make sure that the wires are not pinched by the housing or screws, since the vibration of the compressor can fray over time insulation and cause a short circuit.
Assembly and performance testing
The final stage of work is the reassembly of all components in the reverse order of disassembly. It is important not only to install all the parts in place, but also to check the reliability of the fasteners, especially those that hold the evaporator and the plastic lining.
After installing the plastic panels, make sure that all the latches are in place with a characteristic click, and the screws are tightened tightly, but without overtightening, so as not to crack the plastic. When connecting wires to sensors or a lamp, check the tightness of the connectors.
Before turning on the refrigerator, let it stand unplugged for a while, especially if it was transported or tilted so that the oil in the compressor flows into the crankcase. After turning on, listen to the operation of the unit: there should be no extraneous noise, knocking or humming.
⚠️ Attention: If after assembly the refrigerator makes unusual sounds or does not reach temperature for several hours, immediately turn it off and check that all components are connected correctly.
Checking the door tightness carried out by a simple test with a sheet of paper: clamp the sheet between the door and the body in different places - it should be removed with force. If the paper falls out freely, it means that the seal does not fit tightly and adjustment is required.
FAQ: Frequently asked questions
Do you need to completely defrost the refrigerator before disassembling?
Yes, this is a mandatory requirement. Ice inside the chambers prevents access to the fasteners, and attempting to remove parts with ice will result in the plastic breaking. In addition, moisture can get on the electrical contacts.
Is it possible to remove the door of the Biryusa refrigerator alone?
Technically possible, but highly not recommended. The door is heavy and uncomfortable, there is a risk of dropping it, damaging the floor or the door itself, and injuring your legs. It is better to carry out this operation with an assistant.
What to do if the plastic latch breaks during disassembly?
If the latch breaks off, but the panel itself is held on by other fasteners, you can leave it as is. If the fixation is broken, you can carefully drill a hole and secure the panel with a screw with a wide head or use a special glue for plastic, but this will take time to dry.
How often do you need to disassemble the freezer for cleaning?
Special disassembly and removal of panels is required only for repairs or deep cleaning of the drainage (every 3-5 years). Regular defrosting and washing are available without disassembly and should be carried out as soon as dirt or ice forms.
Where can I find a diagram of my Biryusa model?
Diagrams and instructions are usually found in the technical data sheet of the product. You can also search for information on the manufacturer's official website, indicating the exact model index, which is located on a metal plate inside the chamber or on the back wall.
