Dismantling the upper part of the refrigerator body Biryusa often becomes a necessary step when carrying out complex repairs, replacing the thermostat or troubleshooting wiring problems. The design of these units, despite their apparent simplicity, has its own technical nuances, which, if ignored, can lead to damage to plastic elements or fasteners. Understanding the assembly principle allows you to do the work carefully without damaging the aesthetic appearance of the equipment.
Owners are often faced with the need to access the technical compartment hidden under the decorative cover when the compressor stops turning on or the temperature sensor needs to be replaced. Carrying out the procedure independently requires a minimum set of tools and strict adherence to the sequence of actions. In this article, we will analyze in detail the algorithm for removing the panel, paying attention to various modifications of refrigerators of this brand.
It is important to realize that the top panel not only performs a decorative function, but also protects electrical components from dust, moisture and mechanical influences. Careless movement during dismantling can lead to breakage of the plastic latches, which are extremely difficult to restore at home. Therefore, before starting work, you need to carefully study the design of your particular model.
Necessary tools and preparation of the workplace
Before you begin disassembly, you should prepare the workspace and the necessary tools. For most models Turk you will need a medium-sized Phillips screwdriver, a flathead screwdriver with a thin blade, and possibly some pliers. Good lighting in the work area is a must, as some screws may be hidden in deep recesses.
Free up space around the refrigerator, ensuring access from all sides, especially from the top and back. This will allow you to move freely and not accidentally drop parts you remove on the floor. It is also recommended to place a soft cloth or cardboard on the floor so that the laid body elements do not get scratched.
- 🔧 Phillips screwdriver (PH2) for unscrewing the main screws.
- 🪛 Thin flat screwdriver for carefully snapping off the plugs.
- 🔦 A flashlight for illuminating hard-to-reach places inside the case.
- 🧤 Work gloves to protect your hands from sharp metal edges.
Particular attention should be paid to safety. Before starting any work on disassembling electrical appliances, be sure to disconnect the refrigerator from the power supply by removing the plug from the socket. This is a critical step to prevent the risk of electric shock from accidentally touching bare contacts.
⚠️ Attention: Some models of Biryusa refrigerators have screws painted in the color of the case. Carefully inspect the surface of the panel in bright light so as not to miss hidden fastening points.
Preparing the tools takes only a few minutes, but significantly speeds up the process and reduces the risk of equipment damage. Make sure the blade of the screwdriver fits snugly into the screw slot to avoid stripping the threads. If you work in a cold room, let the plastic warm up to room temperature so that it becomes more elastic.
Features of the design of the top cover of different models
Refrigerators Biryusa are produced in various modifications, and the design of their top panel can differ significantly depending on the year of manufacture and series. In older models, the cover is often attached solely to screws that are visible to the naked eye or hidden under decorative plugs. Modern versions can use a system of hidden latches in combination with a minimum amount of fasteners.
In models with a top freezer, the panel is usually part of a single structure, while in two-chamber versions it can be divided into sections. Understanding what type of unit your unit is helps you choose the right dismantling strategy. Incorrect application of force where the latches should work is guaranteed to lead to failure.
How to determine the type of fastening without instructions?
Visually inspect the end of the top panel. If you see screw holes around the perimeter, this is a screw fastening. If the surface is smooth, and the panel slightly plays when pressed gently, most likely, plastic latches are used.
It is also worth considering the material of manufacture. In budget series, the plastic may be more fragile, requiring special handling when heated or bent. Metal elements, if they are present in the design of the lid, may have sharp edges that can easily injure you.
If you are not sure about the design of your model, it is better to find technical documentation or a photo of the disassembly of a similar device on the Internet. This will help avoid fatal mistakes at the initial stage. In some cases, manufacturers change the fastener design within the same model range, so a visual inspection is more important than general recommendations.
Step-by-step algorithm for dismantling the top panel
The process of removing the top panel begins with a thorough visual inspection of the perimeter of the cover. Locate all mounting points: screws may be located on the front, back, or sides of the end piece. In some models Biryusa the front screws are covered with decorative plastic caps, which need to be carefully pryed off with a thin screwdriver or knife.
After unscrewing all visible screws, do not rush to pull the cover up. Try moving the panel slightly horizontally or check to see if the hidden latches on the sides are holding it in place. Movements should be smooth and confident, without sudden jerks that can break the plastic fasteners.
☑️ Lid removal algorithm
If the panel does not budge, check again for hidden screws. Sometimes one forgotten screw blocks the removal of the entire structure. It is also possible that the panel is stuck or stuck due to contamination; in this case, you can try to slightly warm the plastic with a hairdryer (without overheating!) or gently tap the edges with your palm.
When removing the panel, keep an eye on the wires that may go from the cover to the main body (for example, lamp or sensor wires). If there are such connections, they must first be disconnected by remembering or photographing the color marking of the contacts.
⚠️ Attention: Never use force if the panel is not removable. This is a sure sign that you missed a fastening element or did not correctly understand the principle of fixation.
Successful dismantling ends with the complete separation of the lid from the refrigerator body. Place the removed part on a prepared soft surface with the outside facing down to avoid scratching the front part. Now you have full access to the internal components for diagnostics or repairs.
Access to the thermostat and electrical circuit
After removing the top panel, you have access to the main control unit, where the thermostat and the compressor start relay are located. In refrigerators Biryusa the thermostat is often attached directly to the inner wall or to a special plate under the lid. To replace it, partial disassembly of the internal space of the camera may be required.
The electrical circuit in these models, as a rule, is quite simple and linear. The wires from the plug go to the thermostat, then to the start relay and thermal relay, and then to the compressor windings. Understanding this chain is necessary to correctly diagnose faults. All contacts must be securely fixed; oxidation or loosening of connections is unacceptable.
| Component | Location | Function | Signs of malfunction |
|---|---|---|---|
| Thermoregulator | Under the top panel / inside the chamber | Temperature control | The refrigerator does not turn on or off |
| Start relay | Next to the compressor (bottom) or under the panel | Starting the engine | Clicks, humming, no start |
| Thermal relay | Paired with a start relay | Overheat protection | Shutdown after a short operating time |
| Light lamp | Inside the refrigerator compartment | Backlight | No light when opening the door |
When working with electricians, use multimeter to check the integrity of the circuits and the presence of voltage. This will allow you to determine exactly which element has failed before purchasing a new part. Replacing a working spare part will not solve the problem, but will only waste your time and money.
Pay attention to the condition of the wire insulation. If you find melted areas or cracks, they must be replaced or carefully insulated. Old wiring in refrigerators Biryusa can lose its properties over time, becoming brittle and brittle.
Typical mistakes during disassembly and how to avoid them
One of the most common mistakes is the loss of fasteners. Small screws and self-tapping screws easily roll under the refrigerator or get lost in the carpet pile. To avoid this, use a magnetic tray or small container to place all the removed parts immediately after removing them.
Another common mistake is damage to the plastic latches due to haste or brute force. The plastic on old refrigerators becomes brittle, and careless movement with a screwdriver can break the fastening eye. Restoring such parts requires soldering plastic or using epoxy resin, which does not always give a reliable result.
- ❌ Ignoring disconnection from the network, which is life-threatening.
- ❌ Using excessive force when unscrewing rusted screws.
- ❌ Forgetting to disconnect wires before completely removing the cover.
- ❌ An attempt to pry the panel with a metal object without protecting the edges.
Also, craftsmen often forget about marking the wires. When reassembling, you can easily confuse the contacts, especially if there are more than two of them. Using insulating tape different colors or paper tags will help avoid confusion. This is especially true for models with additional functions, such as No Frost or electronic control.
You should also not neglect cleaning the space under the panel from dust and dirt. years of dust accumulation can cause overheating of electrical components or interfere with the movement of mechanical parts. Simple vacuuming will extend the life of your refrigerator.
⚠️ Attention: If you find traces of oil under the top panel or in the compressor area, this may indicate a refrigerant leak. In this case, further independent repairs without special equipment and skills are not recommended.
Avoiding these mistakes will save you nerves and resources. Accuracy and attentiveness are the main qualities of a home master. Remember that high-quality disassembly is already half of a successful repair.
Assembling and checking the functionality of the refrigerator
Assembling is done in the reverse order, but requires no less care. Make sure that all wires are routed in their intended channels and are not exposed to moving parts or hot elements. Incorrectly routed wiring may be pinched by the cover, resulting in a short circuit.
When installing the top panel, first engage the far latches, and then gently press the front part. Make sure that the panel sits evenly, without distortions or gaps. Only then can the screws be tightened. Over-tightening the screws can lead to plastic deformation or thread breakage.
After complete assembly, connect the refrigerator to the network and listen to the operation of the compressor. Startup should be smooth, without strong vibrations or humming. Check the operation of the lighting lamp and, if any, other indicators. Let the unit run idle for 15-20 minutes to make sure the temperature is stable.
If after assembly the refrigerator behaves strangely (does not freeze, constantly works, makes strange sounds), immediately turn it off and check that all components are connected correctly. Perhaps some contact was not fully established or the polarity was reversed.
The final stage is to install the refrigerator in a permanent place. Make sure that the gap between the back wall and the wall of the room is sufficient for normal air circulation. This will ensure efficient operation of the condenser and extend the life of the compressor.
Is it possible to remove the top panel without moving the refrigerator away from the wall?
In most cases, access from the rear is required to completely remove the top panel, since some of the mounting screws are often located there. If the refrigerator is close to the wall, you will have to move it at least 50-70 cm. Trying to do this without moving it can lead to damage to the wall or the equipment itself.
What to do if the plastic latch breaks during removal?
If the latch breaks off, do not despair. The panel can be fixed with a small amount of superglue or epoxy resin, restoring the geometry of the fastening. As a last resort, you can use a small self-tapping screw to carefully drill a hole at the break point, but this will require care not to damage the internal components.
Do you need to defrost the refrigerator before removing the panel?
Defrosting is not a prerequisite for removing the top panel, since it is located at the top of the unit, further from the evaporator. However, if you plan to climb inside the chambers or work with the water drainage system, defrosting is required. For easy access to the electrics under the cover, just turn off the power.
Where can I find the electrical connection diagram for my Biryusa model?
The electrical connection diagram is usually found in the technical documentation included with the refrigerator. If the documentation is lost, the diagram can often be found on a sticker located on the inside wall of the refrigerator compartment or on the back wall of the cabinet. The diagrams are also available in service manuals on the Internet by model number.
Is it dangerous to change the thermostat yourself?
Replacing a mechanical type thermostat does not pose a high risk if electrical safety rules are followed (disconnecting from the network). However, if you do not have experience working with electrical appliances, it is better to entrust this procedure to a professional. Incorrect installation can lead to incorrect operation of the refrigerator or failure of the compressor.
