A sudden dimming of the light inside the refrigerator compartment or a complete lack of illumination is a signal that cannot be ignored. Refrigerators Biryusa, like any other equipment, require periodic maintenance, and replacing the light source is one of the most common procedures. Many owners mistakenly believe that they need to call a specialist for this, but the process is often so simple that it takes only a few minutes.
Before starting any work, you must clearly understand what kind of ceiling design you are dealing with. Different models refrigeration equipment use different types of fastenings: from simple latches to screw connections. Incorrect force during dismantling can lead to breakage of the plastic diffuser, so it is important to act consistently and without fanaticism.
The main reason for replacement lies not only in comfort, but also in the safety of products. In poor lighting, it’s easy to miss spoiled packaging or traces of mold on shelves. In addition, old incandescent lamps, which are often found in older models, get very hot, which is undesirable for the temperature of the chamber.
⚠️ Attention: Before you start disassembling the lampshade, be sure to disconnect the refrigerator from the power supply. Unplug the plug from the socket to eliminate the risk of electric shock or short circuit from accidental contact with the wiring.
Preparing tools and selecting a new lamp
For successful replacement, you do not need complex professional tools. In most cases, a regular flat-head screwdriver, which can be found in every home, is sufficient. However, if the shade is secured with screws, a small Phillips screwdriver may be needed. It is also recommended to prepare a dry rag to wipe the lampshade from dust and condensation.
A critically important step is the correct selection light source. Refrigerators Biryusa usually use lamps with an E14 base. The standard power is 15 W, but modern LED analogues can be significantly more powerful in terms of luminous flux with lower consumption. It is important to pay attention to the dimensions: the LED lamp should not be too long, otherwise it may rest against the shelf or wall of the chamber.
When choosing between an incandescent lamp and an LED analogue, it is worth considering the temperature regime. Special refrigeration lamps must withstand low temperatures and humidity. Conventional household LED lamps can operate unstable at subzero temperatures if they are not designed for freezers, so it is better to choose specialized solutions.
Removing the lampshade depending on the model
The design of lampshades in refrigerators Turk has changed over the years, so removal methods may differ. In older models, the shade is often a simple cap that is held in place by friction or a single central latch. Newer versions use a side locking system or screw fastening.
If you see that the shade is smooth and has no visible screw holes, it is most likely removed by gently squeezing the tab. This tab is usually located on the side of the door or underneath. You need to act carefully, as plastic becomes brittle in the cold and can crack with a sharp jerk.
In models with screw fastening, you must first unscrew the visible screws. Sometimes they can be hidden under decorative plugs. After removing the fasteners, the lampshade can be removed with a slight pull towards you. Do not pull too hard if you feel resistance - you may have missed one of the latches.
⚠️ Attention: The plastic in the refrigerator compartment becomes very brittle after prolonged cooling. Before removing the lampshade, let the refrigerator stand for a while with the door open or gently warm the plastic with the warmth of your hands to reduce the risk of cracks.
Step-by-step instructions for replacing a light bulb
Once you have reached the lamp, the replacement process becomes technically simple, but requires care. If the lamp is hot (although it should cool down after unplugging), give it time. You need to unscrew the lamp counterclockwise. Do not use excessive force so as not to crumble the base in the socket.
If the lamp burns out and the base remains inside the socket, the situation becomes more complicated. In this case, you should not try to pick out the remains with pliers, as you may damage the contacts. It is safest to use pliers to grab the edge of the base and carefully twist it out, or use a special tool for unscrewing broken lamps.
Installing a new lamp is done in the reverse order. Screw in the light source all the way, but without fanatical pressure. Then install the lampshade in place, making sure that all the latches fit into their grooves with a characteristic click. Check the reliability of the fixation by slightly shaking the lampshade.

Lamp compatibility and characteristics table
To choose the right replacement component, it is important to focus not only on the brand, but also on the technical parameters. Below is a table that will help compare the type of base and permissible power for different series of refrigerators Biryusa.
| Type of base | Standard power | Recommended analog LED | Features |
|---|---|---|---|
| E14 | 15 W | 2-4 W (LED) | The most common option |
| E14 (Mini) | 15 W | 2-3 W (LED) | Shortened bulb for narrow lampshades |
| Special connector | 10 W | LED board | Found in new models with integrated LED backlighting |
| E27 | 40 W | 5-7 W (LED) | Rarely, mainly in old industrial models |
Pay attention to the marking temperature range on the lamp packaging. For a refrigerator, it is critical that the light source operates stably at temperatures from +5 to -20 degrees Celsius. Conventional indoor lamps can flicker or go out in the cold.
Is it possible to use LEDs of higher power?
Theoretically, it is possible, since LED lamps heat up less. However, if the refrigerator has a mechanical light switch, too much current may cause the contacts to spark. It is better to stay within reason, not exceeding the equivalent of 40-60 W of an incandescent lamp.
Electrical problems: when the problem is not in the lamp
Sometimes replacing the light bulb does not bring results, and the light in the camera never comes on. In this case, the problem may lie deeper. The first suspect is limit switch (button), which is located on the body of the refrigerator and is pressed by the door. If it is stuck or oxidized, the circuit does not close.
You can check the button by closing its contacts manually (with the refrigerator turned off) or by ringing with a tester. If the button is working properly, it is worth inspecting the wiring. In older models, the wires could fray or be chewed by rodents if the refrigerator was in a garage or in the country.
It is also worth paying attention to the condition of the cartridge. Due to high temperature or time, the contacts inside could oxidize or burn. If you see traces of burning or smell burning plastic, simply replacing the lamp will not be enough - you will need to replace the socket or the entire backlight assembly.
⚠️ Attention: If you find a melted socket or damaged wire insulation, further operation of the refrigerator without repair is dangerous. In this case, it is better to contact a professional electrician or a service center.
Advantages of switching to LED backlighting
Many owners, when replacing a burnt-out lamp, decide to upgrade the lighting by installing LEDs. This is a reasonable solution that has a number of advantages. Firstly, energy consumption is reduced significantly. Secondly, LEDs practically do not heat up, which makes it easier for the compressor to maintain the temperature.
The light from LED lamps is brighter and whiter, which improves visual control of products. The service life of such light sources is tens of thousands of hours, so the problem of burnout can be forgotten for years. However, you should be prepared for the fact that a high-quality LED lamp is more expensive than a regular “Ilyich light bulb.”
When installing LED strips instead of a standard lamp (as a tuning), it is important to choose the right power supply if the strip is not designed for direct connection to a 220V network. But in the case of Biryusa most often it is enough to simply screw in a ready-made LED lamp of the appropriate form factor.
What to do if a new lamp burns out immediately?
If you are faced with a situation where the lamp burns out almost immediately after being turned on, this may indicate a power surge or a malfunction in the refrigerator's power circuit. It is also possible that the lamp was defective. Try installing a lamp from a different manufacturer. If the situation repeats, it is necessary to check the voltage in the socket and the condition of the wiring inside the refrigerator.
Is it possible to leave the refrigerator open during repairs?
Short-term opening of the door for 10-15 minutes will not harm the compressor or products. However, if you are planning complex wiring jobs that will take longer, it is best to temporarily remove perishable items. This will prevent the chamber from defrosting and unnecessary load on the motor when trying to return the temperature.
Where can I find the electrical circuit diagram for my Biryusa model?
Wiring diagrams are usually found in the technical documentation that came with the refrigerator. If the paper is lost, the diagram can often be found on the back wall of the refrigerator (on a sticker) or on the manufacturer's official website in the support section for a specific model by serial number.
