The need to remove the top cover from the refrigerator Biryusa most often occurs when the compressor is seriously damaged, there is a refrigerant leak, or the insulating material is replaced. Unlike simpler operations such as changing a light bulb or adjusting the legs, this process requires the complete dismantling of the case and compliance with safety precautions. Incorrect actions can lead to damage to the condenser tubes or loss of system tightness.
Before starting work, it is important to understand that the top panel (top) is a load-bearing structural element in many models. It holds the side walls and protects the internal insulation from moisture. Removing the cover is not just unscrewing the bolts, but a sequential procedure for disassembling the entire unit. Read carefully the device of your specific model, since in the old and new Biryusa series the fastening schemes can be radically different.
In this article we will look at all stages of dismantling, the necessary tools and typical mistakes that inexperienced professionals make. If you are not confident in your abilities, it is better to contact the service center, but if the decision is made, follow the instructions with the utmost care.
Preparation of the workplace and necessary tools
The success of the operation to dismantle the top cover depends 90% on proper preparation. A refrigerator Biryusa is a heavy and bulky piece of equipment, so you will need some free space. The best option is to unload equipment onto the floor or wide, stable stools covered with soft material so as not to damage the enamel of the case.
For work you will need a standard home craftsman's kit. The main requirement for tools is serviceability and compliance with the dimensions of the fasteners. Using dull screwdrivers or the wrong keys can cause the edges of the bolts to lick off, turning a simple repair into a long-term problem.
Be sure to have the following tools ready:
- 🔧 Phillips screwdriver (sizes PH2 and PH3) for the main case screws.
- 🔧 Flat-head screwdriver for removing decorative plugs and plastic clips.
- 🔧 Socket wrench or 8 mm/10 mm socket for compressor mounting nuts (if access from below is required).
- 🔧 Pliers with thin jaws for working with clamps and wires.
- 🔧 Container for folding fasteners so as not to lose small parts.
⚠️ Attention: Before starting any work on disassembling the refrigerator, be sure to disconnect it from the power supply! Remove the plug from the outlet. Working with live electrical appliances is deadly.
It is also recommended to have a flashlight on hand, as some fasteners may be located in hard-to-reach, shaded areas. If you have a multimeter, take it with you - it can be useful for checking the integrity of the wiring after removing the cover.
Design features of Biryusa refrigerators
Refrigerators Biryusaproduced by the Krasnoyarsk plant have their own design features. In most classic models, the top cover is a metal sheet coated with polymer paint or enamel. Under it there is a layer of polyurethane foam insulation, which closes access to the insides.
It is important to note that in some modern models with a system No Frost or improved insulation, the top panel can be integrated with the side walls or have hidden fasteners. In such cases, a simple sequence of actions may not work. Always check the technical documentation of the specific model, if it is available.
The cover fastenings are usually located around the perimeter: front, back and sides. However, in a number of modifications, the screws can be hidden under decorative elements or plastic covers. Understanding the general assembly pattern will help you avoid using excessive force.
The metal used in Biryusa cases is quite durable, but can be easily deformed if handled carelessly. This is especially true for the edges of the lid. If you bend the metal during dismantling, when you reinstall it, cracks may form through which the cold will escape.
Procedure for removing the top cover
The process of removing the cover should begin only after the refrigerator is completely defrosted and moved away from the wall. You need to provide access to all sides of the unit. The first step is always to dismantle the door, as it significantly makes the structure heavier and interferes with maneuvers.
To remove the door, open it and find the hinges. They are usually secured with two or three bolts at the top. Unscrew them, holding the door, and carefully remove it from the lower pins. After this, the case will become much lighter.
Next follow the algorithm:
- Remove all visible decorative plugs on the top panel. They can be located in front, above the door, or in the back, against the wall.
- Unscrew the fastening bolts around the perimeter of the cover. Be careful: some screws may be longer than others.
- Carefully lift the back of the cover. Often it is held on by latches or simply lies on the side walls.
- If the cover does not budge, check if wires or tubes coming from the compressor or thermostat are in the way.
⚠️ Attention: Do not try to forcefully tear off the cover if it does not move. Check for hidden fasteners or latches that may have been missed.
On some models, the top cover is also secured in the rear engine compartment area. It may be necessary to remove the rear metal panel (crankcase) to gain access to the bottom fastenings of the top cover. This is especially true for models with a bottom freezer.
☑️ Checklist before lifting the lid
Working with wiring and internal components
After the bolts are unscrewed, do not rush to completely remove the cover. Electrical wiring often runs underneath it, leading to a thermostat, light bulb, or temperature sensors. A sudden movement may break the wires or damage the insulation.
Carefully inspect the space under the cover. If you see wiring harnesses, carefully unplug the connectors. To do this, press the connector latches and pull them to the sides. Never pull the wires themselvesonly by the plastic connector housings.
In models with electronic control, the main control unit may be located under the top cover. In this case, special care is required. Static electricity or mechanical damage to the board will lead to expensive repairs.
If the wires interfere with removing the cover, they can be temporarily moved aside, but it is better to completely disconnect the connectors. This will ensure safety and freedom of action.
Table problems during dismantling
During the disassembly process, craftsmen often encounter typical difficulties. Below is a table that will help identify the problem and find a solution.
| Problem | Possible cause | Solution |
|---|---|---|
| The cover does not lift | Hidden bolts are not unscrewed rear | Check the fastenings in the engine compartment |
| The edges of the bolts are licked | Using the wrong screwdriver | Use an extractor or pliers |
| Interfering wires | Connectors are not disconnected | Carefully disconnect the connectors |
| The cover is deformed | Previous careless repair | Align the edges before installation |
When working with fasteners, try not to drop the bolts inside the refrigerator body. If this happens, do not shake the unit. It is better to carefully remove the part through the technological holes or using a magnet on a long handle.
What to do if the bolt is rusty?
If the bolt does not unscrew due to corrosion, drop a little penetrating lubricant (for example, WD-40) on it and wait 10-15 minutes. Then try to carefully develop it, slightly turning it back and forth.
Specifics of models with a bottom freezer
Refrigerators Biryusa with a bottom freezer have a more complex top design. In such models, an air duct often runs under the top cover or elements of a water drainage system are located. Dismantling here requires increased care.
In some series, the top panel can be connected to an internal plastic box. When removing the metal cover, care must be taken not to damage the plastic guides. They are quite fragile, especially if the refrigerator has been in use for a long time and the plastic has lost its elasticity.
Also in such models, the fastening of the lid can be reinforced with additional brackets on the sides. Inspect the side walls at the top: if there are holes for screws, they must be unscrewed before lifting the top.
⚠️ Attention: The design of refrigerators may vary depending on the year of manufacture. If you cannot find the mountings described, check the official diagram for your specific model on the manufacturer's website.
After removing the cover, you will have access to the top of the evaporator (in models with a weeping wall) or to the cold distribution system. Be careful not to damage the aluminum tubes.
Completion of work and reassembly
After completing the repair work, you must correctly reinstall the top cover. Make sure that all internal components are in place and that nothing is preventing the metal from sealing tightly.
First secure the cover to the rear fasteners, then align it with the front edge. Tighten all the bolts, but do not tighten them all the way all at once. First, tighten all the screws, make sure that the cover sits evenly, without distortions, and only then finally tighten the fasteners.
Check the gaps between the cover and the side walls. They should be uniform around the entire perimeter. If the cover is skewed, loosen the screws and adjust its position. A loose fit will lead to loss of cold and increased load on the compressor.
After installing the cover, connect all the electrical connectors that were disconnected. Reinstall the decorative caps. Only after complete assembly can you plug in the refrigerator.
Frequently asked questions (FAQ)
Is it possible to remove the top cover without removing the refrigerator door?
Technically this is possible, but it is highly not recommended. The door creates a significant advantage and makes it difficult to maneuver. In addition, careless movement can damage the hinges or the door itself. It is better to spend 5 minutes removing it.
What to do if after assembly the refrigerator begins to make noise?
Check whether the top cover does not touch the vibrating parts of the compressor or tube. Also make sure all bolts are tightened evenly. Sometimes the noise can be caused by the wiring touching the case or the fan.
Is it necessary to change the seal when removing the cover?
In most Biryusa models there is no separate seal between the top cover and the case; tightness is ensured by a tight fit of the metal and a layer of foam. However, if you find damaged insulation, it is better to replace it or restore it with polyurethane foam.
Where can I find a fastening diagram for my model?
Disassembly diagrams (explosion diagrams) can often be found in service manuals on the Internet using the full model code (located on a sticker inside the camera). Forums of home appliance repair specialists are also useful.
Is it dangerous to remove the cover yourself?
The main danger is the risk of electric shock (if you do not unplug it) and the risk of damage to the refrigerant pipes. If you are not confident in your actions, it is better not to risk it and call a professional.
