The sudden loss of light inside the refrigerator compartment always takes you by surprise, especially when you urgently need to find food. Equipment owners Biryusa often encounter this problem, since standard incandescent lamps installed at the factory are not durable. Replacing the light source is a simple procedure, but requires care so as not to damage the fragile plastic shade or wiring.
Before proceeding with dismantling, it is necessary to completely de-energize the unit by removing the plug from sockets This is a basic rule electrical safety, ignoring which can lead to a short circuit or electric shock, even if the voltage in the network seems low. Working with electrical appliances always begins with turning off the power.
Next, you should determine the type of base and design of the diffuser, since they may differ in different models. Biryusa they may differ. Older versions often used E14 threaded sockets, while modern ones often used LED modules or G4 sockets. Understanding the design will help you choose the right tool and avoid unnecessary effort when removing the protective cap.
Diagnostics and preparation of tools
The first step will be a visual inspection of the interior of the refrigeration chamber. You need to understand why the lamp burned out: it is natural wear and tear of the filament or a power surge. If the light bulb turns black or a broken spiral is visible inside, then replacement is inevitable. However, if the second lamp burns out in a short time, it is worth checking voltage stability on the home network.
For work you will need a minimum set of tools that can be found in any home. The main requirement is that the tool must be in good working order and clean, so as not to carry dirt inside the refrigerator. Dirt and grease can cause poor contact in the socket.
- 🔦 A flashlight or turned on smartphone camera to illuminate the work area if the main lighting in the room is insufficient.
- 🪛 A flat-head screwdriver with a thin blade for carefully prying up the plastic latches of the lamp.
- 🧤 Dry cloth gloves or a napkin so as not to leave greasy marks on the new lamp and glass.
It is important to prepare the new lamp in advance, making sure that its power does not exceed that recommended by the manufacturer. Typically for refrigerators Turk this parameter is no more than 15-25 W for incandescent lamps. Excessive power can lead to melting plastic socket and deformation of the internal wiring.
⚠️ Attention: Never use a metal tool to unscrew a broken light bulb from a live socket. Even if the refrigerator is unplugged, a residual charge may remain in the capacitors.
Removing the lampshade and access to the lamp
The design of the lampshade in refrigerators Biryusa can be made in the form of a separate cap from translucent plastic or integrated module. In most classic models, the lampshade is secured with one or two latches, or is held in place by a friction fit. To remove it, you need to act slowly and without jerking.
Find the junction of the lampshade with the body of the refrigerator or the back wall of the chamber. Often there is a small technological gap or recess. Carefully insert the blade of a flat-head screwdriver wrapped in a thin cloth so as not to scratch the plastic, and lightly apply pressure or twist the tool. You should hear a characteristic click of the plastic latch snapping off. If the lampshade is held on by a screw, which may be hidden under a decorative plug, remove it first. Screws in refrigerators often have a specific head, but usually a standard cross or flat slot is used. After unscrewing the fasteners, the lampshade can be easily removed downwards or to the side, allowing access to the base. plastic latch.

After unscrewing the fasteners, the lampshade can be easily removed downwards or to the side, providing access to the base.
☑️ Algorithm for removing the lampshade
In some models, especially in two-chamber refrigerators with the No Frost system, access to the lamp can be combined with dismantling the control panel or air duct. In such cases, it is better to turn to service documentation a specific model so as not to break complex plastic fasteners, which become very fragile in the cold.
Types of bases and choice of replacement
After gaining access to the lamp, you need to determine the type of base. The brand's refrigerators Biryusa historically have used several standards. The most common is the threaded base E14 (minion), which is visually smaller compared to standard household E27. The thread diameter is 14 mm.
In more modern or compact models, pin sockets may be found G4 or G9. Lamps with such sockets are small capsules that are simply inserted into the socket. It is important not to confuse the voltage: refrigerators use a 220V network, but some LED modules can operate from 12V through a built-in transformer.
| Type of base | Appearance | Typical power | Recommended replacement |
|---|---|---|---|
| E14 | Threaded, narrow | 15-25 W | LED E14 (cold light) |
| G4 | Two pins, distance 4 mm | 10-20 W | LED capsule G4 220V |
| Integrated LED | Board with LEDs | 1-3 W | Original Biryusa module |
| Fluorescent lamp | Tube with contacts on the sides | 6-13 W | Specialized tube T5/T8 |
When choosing a replacement, you should consider installing an LED (LED) lamp. They practically do not heat up, which is critical for the operation of the refrigeration unit. Incandescent lamps, on the contrary, emit heat, forcing the compressor to work harder to compensate for the excess heat inside the chamber.
Is it possible to install an LED lamp of higher power?
It can be physically installed if the base matches. However, if the LED lamp has a large driver, it may not fit under the lampshade. Also, some cheap LED lamps create radio interference, which can theoretically affect the operation of the control electronics, although this is rare in simple Biryusa models.
The process of replacing a light source
The process of unscrewing the old lamp itself requires caution. If you are using an E14 base, hold the lamp by the base and not by the glass bulb, especially if it is hot or you have just come from the cold (the glass may break due to temperature changes). Unscrew counterclockwise without excessive force.
In the case of capsule lamps (G4), you just need to pull them towards you. Sometimes the contact may be tight due to oxidation. If the lamp cannot be removed by hand, you can carefully use pliers, but be sure to go through a layer of fabric so as not to crumble the glass. Try not to touch the glass part of the new halogen lamp with your fingers, as oil from the skin will lead to local overheating and rapid failure.
Installing the new lamp is done in the reverse order. Screw in or insert the light source all the way, but without fanaticism. Excessive force when screwing in may cause the base to “stick” to the socket or the internal ceramics of the socket to burst. Attention: If you feel strong resistance or hear a cracking sound when screwing in a new lamp, stop immediately. Check that the correct base type is selected. An attempt to screw an E27 socket into an E14 socket (or vice versa, using adapters) is unacceptable due to the risk of a short circuit. cartridge.

After installing the light source, it is necessary to return the lampshade to its place. Make sure that the wires are not caught under the latches or pinched by the housing. The lampshade should fit tightly into place, without gaps through which light could escape or warm air could penetrate.
Features of replacement in models with LED modules
Modern refrigerators Biryusa are increasingly using not replaceable light bulbs, but solid LED modules. They are a plastic platform with LEDs and a diffuser soldered on it. Such designs last for years, but if they fail, simply replacing the “pear” will not help.
To replace such a module, you will need to purchase an original spare part by catalog number. Universal solutions are rarely suitable here due to differences in the geometry of the fasteners and connection connectors. Disassembling the module itself to replace individual LEDs requires soldering skills and is usually impractical in a domestic environment.
The process of dismantling the module often involves removing the entire back panel or top of the refrigerator compartment. It is necessary to disconnect the power connector, which may be protected by a latch. Press the latch carefully so as not to break its plastic “ears.”
Checking functionality and assembly
After the new lamp is installed and the lampshade is returned to its place, you can begin testing. Plug in the refrigerator. The door must be open to activate the switch (button or magnetic sensor) that turns on the light. In some models, the light comes on when you open it, in others, when you press a button that simulates closing the door (depending on the logic of the sensor).
If the light comes on, close the door and listen. The click of the switch should be clear. If the lamp flashes or burns at full intensity, check the tightness of the contact of the base in the socket. Perhaps the cartridge petals are too spread out or, conversely, too compressed. In this case, after turning off the power to the unit again, you need to carefully bend the contacts.
Make sure that after assembly there are no unnecessary parts, tools or pieces of insulation left in the chamber. Foreign objects can get into the air circulation system (on No Frost models) and cause noise or block the fan. Also check whether the new shade or lamp does not block the air flow.
- ✅ Check the tightness of the door seal after a long repair job, since the door could remain open for a long time.
- ✅ Make sure that the temperature in the chamber begins to decrease at a normal rate after switching on.
- ✅ Check for the absence of extraneous buzzing or vibration that may have appeared during operation.
Frequently asked questions (FAQ)
Why do the bulbs constantly burn out in the Biryusa refrigerator?
Frequent replacement of bulbs may indicate power surges in mains, poor contact in the socket (sparking) or the use of lamps of higher power than permitted. The cause may also be compressor vibration, which destroys the filament of conventional lamps. Solution: install an LED lamp that is resistant to vibration and check the voltage in the socket.
Is it possible to put an LED lamp in the Biryusa refrigerator instead of a regular one?
Yes, it is possible and even necessary. Light-emitting diode lamps (LED) consume less energy, do not heat up and last many times longer than incandescent lamps. The main thing is to choose a lamp with a suitable base (usually E14) and a shape that will fit under the lampshade. It is recommended to choose lamps marked “for refrigerators” or with a wide operating temperature range.
What to do if the lamp base remains in the socket?
If the bulb comes off and the base remains inside, you need to turn off the power to the refrigerator. Then use thin-nose pliers or tweezers to carefully grab the edge of the base and unscrew it counterclockwise. You can use a strip cut from a plastic bottle: insert it between the base and the wall of the socket, turn it and pull it out. Do not pick inside the socket with a live metal screwdriver!
Where can I find the part number to replace the LED module?
The part number (part number) is usually indicated on the sticker of the module itself or in the technical documentation (passport) of the refrigerator. You can also find it on the manufacturer’s official website in the “Spare parts” section for the model of your unit or ask at the Biryusa authorized service center.
