Modern household appliances, such as Biryusa, are reliable, but even time-tested models require periodic maintenance. Often, owners are faced with the need to access internal components hidden under the top cover: a burnt out light bulb, a failed thermostat, or damaged wiring. Independent dismantling of this part of the case allows you to save on calling a technician and quickly eliminate the malfunction, returning the unit to functionality.
The process of removing the cover seems simple, but the design of refrigerators Biryusa has its own technical nuances, ignoring which can lead to breakage of the plastic latches or damage to the enamel. Safety and the sequence of actions are the key factors of success. In this article, we will analyze in detail the algorithm of actions, the necessary tools and typical mistakes that inexperienced users make when trying to get to the top of the refrigerator.
Before you start working, it is important to understand that you are dealing with an electrical appliance. Any manipulations with internal components require prior disconnection from the network. This is not just a formality, but basic rule electrical safety, which protects against electric shock and short circuit. Preparing the workplace and having the right tools will take no more than 10 minutes, but will ensure comfort and safety of the entire repair process.
Necessary tools and preparation of the workplace
High-quality repairs begin with proper preparation. To dismantle the top panel of the refrigerator Biryusa you do not need a complex professional tool, however, using unsuitable objects can lead to broken bolt heads or scratches on the body. A standard home craftsman's kit usually contains everything you need, but it's worth checking the availability of specific items in advance.
The main tool will be a Phillips screwdriver, preferably with a magnetic tip, since the bolts are often located in hard-to-reach places and you don’t want them falling inside the case. Some models may use slotted screws or even special fasteners, so a visual inspection before starting work is required. You may also need a plastic spatula or an old bank card to carefully pry off the decorative plugs.
- 🔧 Phillips screwdriver (size PH2 or PH3) for the main fasteners.
- 🪛 Flat screwdriver (narrow blade) for prying up the plugs and plastic clip.
- 💡 Flashlight or headlamp for illuminating dark areas inside the case.
- 🧤 Work gloves to protect your hands from the sharp edges of the metal case.
Organize your work space so that you have free space around the refrigerator. Remove carpets and unnecessary objects that may interfere with movement. Prepare a container for storing fasteners in advance so as not to lose small screws that tend to roll under furniture. If the floor is slippery, lay cardboard or fabric for stability.
⚠️ Attention: Never use metal objects (knives, chisels) to pry up the plastic elements of the case. Metal easily leaves deep scratches on the enamel and can split fragile plastic, which will make subsequent assembly impossible without replacing parts.
Electrical safety measures and primary diagnostics
The first and most important step is to completely de-energize the device. Unplug the power cord from the outlet. Do not rely on the fact that the refrigerator is turned off by a button or temperature regulator - to carry out work on electrical circuits, a physical break in the circuit is required. This ensures that accidental contact with the contacts will not result in electric shock.
After disconnecting, let the equipment stand for 10-15 minutes. This is necessary not only to discharge the capacitors in the start relay, but also to redistribute the refrigerant in the system if you plan to touch the evaporator tubes that may run at the top. At this time, conduct an initial visual inspection of the top panel.
Inspect the joints of the lid and side walls. Please note that there are additional screws that may be hidden under decorative stickers or plastic plugs. In older models Biryusa fasteners are sometimes hidden in the depths of the ventilation holes. Careful inspection at this stage it will save you time and nerves during the disassembly process.
☑️ Preparation for dismantling
If you notice signs of corrosion around the fasteners, pre-treat them with a penetrating lubricant (for example, WD-40) and leave for a few minutes. Rust can tightly “grab” the bolt, and an attempt to unscrew it by force will lead to licking of the edges. Accuracy and patience are your main allies.
Algorithm for dismantling the top cover of the refrigerator
The process of removing the panel may vary slightly depending on the specific series Turkish, but the general principle remains the same. The cover is usually secured with several screws around the perimeter and is held on by guides or latches. You should always start by searching for and unscrewing visible fasteners.
Remove all available screws located on the top plane and at the ends adjacent to the side walls. Sometimes two screws may be located on the front, under the trim strip above the refrigerator door. After removing all fasteners, do not pull the cover upward sharply. Try to move it slightly back or forward to understand the principle of fixation.
| Model type Biryusa | Location of the main screws | Type of panel fastening | Dismantling feature |
|---|---|---|---|
| Classic (2 chamber) | 4 screws in the corners on top | Guides + latches | Requires shift back |
| Small-sized (1-chamber) | 2 screws in front, 2 back | Only screws | Simple vertical removal |
| Ditch Series | Hidden under the decor strip | Plastic clips | You need a spatula for opening |
| No Frost models | On the perimeter and inside vents | Combined | Careful with sensors |
If the panel does not give in, check if the wiring is holding it. In some modifications, the wire from the lamp or thermostat can be routed through the hole in the cover with a minimum margin. A sudden movement will lead to a wire break or the lamp base being pulled out. Carefully lift one edge of the cover and look inside, assessing the tension of the communications.
What to do if the screw is rusty and does not turn?
If you are faced with rusted fasteners that do not respond to the force of a screwdriver, do not use excessive force - this will lead to the splines breaking off. Apply penetrating lubricant generously to the joint and leave for 15-20 minutes. You can try gently tapping the bolt head with a hammer (through the spacer) to loosen the rust. If this does not help, use the heating method (be careful not to melt the plastic around it) or try to drill out the cap with a drill, but this is a last resort.
To remove the cap, grab its front and back parts (or the side protrusions, if any). Using a smooth but firm motion, lift the panel. If you hear the characteristic click of plastic clamps, it means the process is going correctly. Place the removed part on a soft surface to avoid scratching the front side.
Access to internal components and wiring
After removing the top panel, you will have access to the main components of the top of the refrigerator. The light bulb socket, thermostat terminals, and in some models, the compressor start relay are usually located here, if it is located at the top point. Be careful: the metal edges of the technological holes may be sharp.
If your goal was to replace the lamp, then in classic models Turkish the socket is often mounted directly into the wall or into a plastic shade secured under the cover. To replace, disconnect the wires (after remembering or photographing the connection diagram) and unscrew the old socket. Install a new one, observing the polarity if it is marked, although this is not critical for an incandescent lamp.
- 💡 Lamp holder: often has a threaded connection or is attached with snaps.
- 🌡️ Thermoregulator: capillary the tube is very fragile, avoid bending it.
- 🔌 Terminal block: the place where the wires are connected, requires caution when disconnecting.
When working with the thermostat, remember that its sensitive element (capillary) runs inside the chamber. When removing the cover, make sure that you do not pull the regulator wires too hard so as not to tear it away from the inside wall of the refrigerator. If it is necessary to replace the regulator itself, access to the fasteners of its housing is also often opened precisely after removing the top panel.
⚠️ Attention: The capillary tube of the thermostat is filled with refrigerant and is very thin. Any deformation, crease or puncture will lead to loss of sensitivity of the sensor and its failure. Work with it only with your fingers, without using pliers.
Typical problems during disassembly and ways to solve them
Owners of refrigerators Biryusa of different years of manufacture may encounter a number of specific difficulties. Old models often suffer from “stuck” fasteners due to humidity and temperature changes. New models may have plastic latches that are too tight, which are dangerous (if the refrigerator has not had time to warm up after defrosting).
One of the common problems is the breakage of the plastic fastening ears when trying to remove the panel by force. If you feel strong resistance, stop. Double-check for hidden screws. Sometimes additional fasteners may be located inside the refrigerator compartment, on top, under the decorative trim. Carefully study the instructions for your specific model, if it is still available.
If the screw is still broken, you can try using a rubber layer between the screwdriver and the head to improve grip, or use a screw extractor. As a last resort, if the head is accessible, you can carefully cut it with a hacksaw or a grinder to remove the cover, and then drill out the remaining bolt.
Assembly and performance testing
Assembly is performed in the reverse order. Make sure that all wires are laid in the channels intended for them and do not fall under fasteners or moving parts (if we are talking about doors, although there are none at the top). The wiring should not touch hot parts (for example, the capacitor if it runs around the perimeter) or sharp metal edges.
Install the top panel into place, aligning the guides. Gently press until the latches click (if there are any), and then tighten all the screws. Do not overtighten the fasteners: the plastic may crack, and the threads in the metal case may be stripped. Tighten the screws crosswise for an even fit.
After assembly, connect the refrigerator to the mains. Check the operation of the light bulb (if replaced) and listen to the compressor start. Make sure that there are no extraneous vibrations that could occur due to a loose lid. If everything works properly, the repair can be considered complete.
Frequently asked questions (FAQ)
Can it be removed top panel without moving the refrigerator away from the wall?
In most cases, this is impossible or extremely inconvenient. Space is required on the back and sides to access the rear screws and safely remove the cover. In addition, moving the unit aside is necessary to provide ventilation and access to the rear wall, where additional wiring may be located.
What to do if, after assembly, the refrigerator stops freezing?
Most likely, during disassembly the thermostat was damaged or disconnected, or the capillary tube was pinched. Also check to see if the fan wire has been accidentally disconnected (on No Frost models). Repeated disassembly and checking of all connections is required.
Is it necessary to drain the freon before removing the top panel?
No, dismantling the metal housing cover does not require draining the refrigerant. This is only necessary if you plan to solder the evaporator or condenser tubes, which can pass inside the case, but the cover itself can be removed without breaking the tightness of the system.
Where can I find the wiring diagram for my Biryusa model?
The diagrams are usually located on the inside of the back wall of the refrigerator (metal sheet) or in the technical documentation (passport products). Also, electrical diagrams can be found on the Internet using the exact model number indicated on the nameplate.
Is it possible to operate a refrigerator without a top cover?
For a short time (for diagnostics) - yes. But constant operation without a cover is not recommended: air circulation is disrupted, dust and moisture enter the housing, which can lead to corrosion and short circuiting of electrical contacts. In addition, the lid acts as sound insulation.
