The need to remove the top panel on the refrigerator Biryusa most often occurs when replacing a burnt-out light bulb, repairing a thermostat, or troubleshooting a control unit. Owners of old and new models are faced with design features that require a careful approach. Incorrect handling of plastic elements can lead to breakage of the latches, so it is important to know the exact sequence of actions.
In this article we will analyze in detail the process of dismantling the decorative and protective elements of the case. You will learn what tools are needed, how to find hidden screws and what safety measures must be observed. Proper disassembly will allow you to diagnose or replace parts without damaging the appearance of the equipment.
Before starting work, be sure to disconnect the device from the electrical network. This is critical because you will be working with live parts or in close proximity to electrical contacts. Even if you are only changing a light bulb, the risk of a short circuit due to careless movement is high.
Preparation of tools and workplace
To successfully perform dismantling, you do not need a complex professional tool. However, the presence of high-quality devices will greatly simplify the task and reduce the risk of damage to fasteners. Prepare your work area in advance: the table should be stable, and the surface covered with a soft cloth so as not to scratch the parts when removing.
- 🔧 Flat blade screwdriver - necessary for prying off plugs and working with screws.
- 🔩 Phillips screwdriver (PH1 or PH2) - the main tool for unscrewing self-tapping screws.
- 🧤 Gloves - will protect your hands from the sharp edges of the metal inside the case.
- 📱 Flashlight - to illuminate the interior of the refrigerator compartment.
In some models, the screws may be hidden under decorative stickers or plugs. They must be carefully removed so as not to damage the plastic. If the screws are covered with rust, pre-treat them with a penetrating lubricant, but be careful not to get the chemicals on the products or seals.
⚠️ Attention! Do not use a metal knife or sharp objects to pry up panels unless you have a plastic spatula handy. Metal easily leaves deep scratches on glossy plastic and can damage internal wiring.
Pay special attention lighting. Refrigerator interiors are often dark, and poor visibility may cause you to miss an important fastener. Good light will allow you to see microcracks in the plastic, which can develop if handled carelessly.
Design features of Biryusa refrigerators
Refrigerators Biryusa have their own design features depending on the year of manufacture and model. Old Soviet and post-Soviet models were often equipped with metal panels that were bolted on. Modern versions use more plastic and hidden latches.
It is important to understand where exactly your thermostat is located. In most cases, it is located inside the refrigerator compartment, but the control panel can be moved outside or hidden under the top cover. Dismantling depends on whether you need to remove only the decorative trim or the entire top casing.
If you have a model with a remote thermostat, the control panel may be located on the outside of the case. In such cases, access to the internals is achieved by removing the top cover or side panels. Study the appearance of your unit to choose the right strategy.
It is worth noting that in models with a system No Frost (although this is rare for Biryusa, a drip system is more common) the design may be more complex due to the presence of additional air ducts and sensors. In standard two-chamber models with drip defrosting, everything is simpler.
Removing the top cover of the refrigerator
Removing the top panel is the first step in accessing the internal components. Most often, this is where the thermostat and electrical wiring are hidden. The process begins by inspecting the perimeter of the cover.
Find the mounting screws. They can be located in front, behind or on the sides of the top panel. Sometimes they are hidden under plastic plugs, the color of which matches the color of the case. Carefully pry them off with a flat screwdriver.
☑️ Checklist before removing the cover
After unscrewing all visible screws, do not rush to pull the lid up. It can be held on by latches or pressed against the side walls. Using light rocking movements, try to move the element. If the cover does not budge, check to see if there are any screws left in the back of the compressor.
In some modifications, the top panel is part of a single casing that covers the top of the housing. In this case, you may need to loosen the fastenings of the side walls. Plastic guides easily break with a sharp jerk, so act smoothly.
⚠️ Attention! When removing the top cover, be careful with the wires leading to the light bulb and thermostat. They may be short, and a sudden movement will lead to broken contacts or pulling out terminals from the connectors.
Removing the control panel and thermostat
After gaining access to the top of the refrigerator, you can begin to dismantle the control panel. This is where thermostatis located, which most often requires replacement or inspection. In older models, the control knob is simply removed by force; in new ones, it can be secured with a locking screw.
To remove the temperature control knob, pull it towards you. If it cannot be removed, inspect the end of the shaft - there may be a small hole for a stopper there. Use a thin wire or an awl to press the latch and at the same time pull the handle.
The control panel itself is attached to the body with screws. After unscrewing them, the block can be removed. Pay attention to the capillary tube of the thermostat. It is very thin and sensitive to creases.
- 🔌 Disconnect the electrical connectors, having previously photographed their position.
- ❄️ Carefully remove the capillary tube from the evaporator without using excessive force.
- 🧩 Remove the decorative frame if it interferes with access to the fasteners.
If you change the thermostat, the new element must have similar characteristics. Installing an unsuitable sensor will lead to incorrect operation of the refrigerator: it will either freeze constantly or not turn on.
How to check the serviceability of the thermostat?
To check the thermostat, you can use a multimeter in dial mode. At room temperature, the contacts should be closed (unless it is a thermostat with defrost). When placing the sensor in the cold (freezer), the circuit should open. If there are no changes, the part is faulty.
Replacing the lighting lamp and removing the ceiling
A common reason for disassembly is replacing a burnt-out lamp. In refrigerators Turyusa, the lampshade is usually located on the back or side wall of the chamber, or in the upper part. Access to it may be limited by shelves or the control panel itself.
The lampshade is secured with latches or one screw. If there is no screw, carefully pry up the edges of the plastic diffuser with a flathead screwdriver. Proceed with caution, as plastic becomes brittle in the cold and may crack.
Replace the lamp with a similar one. Use only special refrigeration lamps designed for low temperatures and vibration. Conventional household lamps can burst due to temperature changes.
| Type of malfunction | Probable cause | Required action |
|---|---|---|
| Lamp does not light | Lamp burnt out or poor contact | Replace the lamp, check the socket |
| The lamp is constantly on | The door switch is faulty | Replace or repair the switch |
| The light is flashing | Problem with the wiring or block | Check the contacts and wires |
| Cracks in the ceiling | Mechanical damage | Replace the diffuser |
After replacement, reassemble everything in the reverse order. Make sure that the lampshade fits tightly and does not wobble. A loose lampshade may prevent the door from closing or fog up.
Assembly and performance testing
Assembly is performed in the reverse order. The main rule is not to overtighten the screws. The plastic of old refrigerators can be dry and easily crack when re-tightening.
Make sure that all wires are laid in their channels and are not pinched by the case. The capillary tube of the thermostat should lie freely, without creases or tension. Any damage to the tube will result in freon leaking from the control system.
After complete assembly, turn on the refrigerator. Check the lamp operation: it should light up when the door is opened and go out when closed. Evaluate the operation of the thermostat - after a while the compressor should turn on and start cooling.
⚠️ Attention! If your refrigerator makes unusual noises or does not cool after assembly, unplug it immediately. It is possible that an important component was touched during installation or the tightness of the system was broken.
Check the tight fit of all panels. There should be no gaps anywhere through which moisture or dust can get inside. If the decorative frame is not level, remove it and reinstall it, checking the guides.
Frequently asked questions (FAQ)
Is it possible to remove the control panel without turning off the refrigerator?
It is strictly not recommended. You will work near 220V electrical contacts. Even a momentary short circuit can damage the control unit or lead to electric shock.
What should you do if the screws on the panel are rusty and won't come out?
Use a penetrating lubricant (such as WD-40), but apply it in spots so as not to stain the food. Give the lubricant time to work. If the cap is torn off, try carefully drilling it out or using a screw extractor.
Where can I find the markings for a replacement thermostat?
The markings are usually marked on the metal body of the thermostat itself. To see it, you often have to partially dismantle the assembly. Write down the model before complete removal.
Why does it burn out again after replacing the lamp?
The reason may be power surges, a faulty socket (poor contact causes sparking) or the use of a lamp of inappropriate power. Check the voltage in the network and the condition of the cartridge contacts.
