Sudden shutdown of light inside the refrigerator compartment - a situation that can take any owner of household appliances by surprise Biryusa. Darkness makes it difficult not only to find the product you need, but also to fully assess the condition of stored supplies and notice traces of condensation or frost on the walls. Often the problem is solved by simply replacing a burnt-out lamp, which you can do yourself without calling a specialist.
Modern models, such as Biryusa 133, Biryusa 6 or older Soviet modifications, have their own design features in the organization of internal lighting. In some places it is a classic incandescent lamp, and in others it is an economical one. Understanding exactly what type of light source is installed in your unit will be the first step to a successful repair. LED. Understanding exactly what type of light source is installed in your unit will be the first step to a successful repair.
In this article we will analyze in detail the algorithm of actions, the necessary tools and safety measures. You will learn how to properly dismantle the protective lamp without damaging the plastic fasteners, and what power lighting fixture to choose for replacement. Following simple rules will allow you to return comfort when using the refrigerator in a matter of minutes.
Preparation for repairs and safety measures
Before you begin any manipulations with electrical appliances, you must ensure your own safety. The refrigerator is a 220-volt device, and careless handling of electrical components may result in electric shock. Even if the lamp seems easily accessible, the risk of a short circuit if the contacts are accidentally touched by a screwdriver or a metal object remains high.
The first and most important rule is to completely de-energize the equipment. You should not rely only on the switch in the socket, if there is one, or the button on the case. The safest thing to do is to unplug the plug from the socket to completely break the electrical circuit. This will eliminate the possibility of accidentally turning on the compressor or backlight when your hands are inside the chamber near the wiring.
⚠️ Attention: If the outlet is located in a hard-to-reach place (behind a cabinet or in a niche), ask someone to help pull out the plug so as not to move the heavy unit yourself and not damage the flooring or hoses.
After turning off the power, prepare your workplace. You may need a stepladder or a stable chair if the refrigerator is tall, as well as an external light source such as a flashlight or table lamp, as natural light may not be available. Collect all the necessary tools in advance so as not to be distracted during the work process.
☑️ Preparing to replace the lamp
Necessary tools and lamp selection
To successfully replace the light source in the refrigerator Biryusa no complex professional tool is required. In most cases, the minimum set that can be found in any home craftsman’s drawer is sufficient. The main thing is to choose the right type of lamp, since using the wrong type of lamp can lead to melting of the lampshade or damage to the wiring.
Most often in refrigerators of this brand, incandescent lamps with a base are used E14 (minion) or, less often E27. The power usually does not exceed 15-25 watts. It is important to consider that modern LED analogues may not work correctly with thermostats of older models or have an inappropriate shape, so a classic incandescent lamp is often a more reliable choice for refrigerators.
Here is a list of what you will need for work:
- 🔦 A flashlight or an additional light source for working in the dark.
- 🔧 A screwdriver (flat or Phillips) in case the lampshade is secured with screws.
- 🧤 Dry cloth gloves or clean rags so as not to leave greasy marks on the glass of the new lamp.
- 💡 A new lamp of the appropriate type and power.
If you plan to install an LED lamp, make sure it is designed to operate in low temperature conditions. Conventional LED lamps may not light up in the cold or quickly fail. Also pay attention to the dimensions: the base may be standard, but the bulb of the LED lamp itself is often wider, which may interfere with the installation of the shade.
Removing the lampshade and old lamp
The process of removing the protective cap (shade) depends on the specific model of your refrigerator Biryusa. In older models, the lampshade is often attached to a screw that needs to be unscrewed. Newer versions, such as Biryusa 108 or Biryusa 134, widely use plastic latches that do not require the use of tools for dismantling.
If you see a screw, carefully unscrew it counterclockwise. If there is no screw, carefully inspect the lamp housing. Usually the latches are located on one of the sides or on the top. It is necessary to gently press the latch with your finger and at the same time pull the lampshade towards you or move it to the side. Act without excessive force so as not to break the plastic, which becomes more fragile in the cold.
After removing the protective element, you will have access to the lamp base. Allow the old lamp to cool if the refrigerator has just been running, although this is not critical if it is turned off. Unscrew the lamp counterclockwise. If the base is rusty or stuck, do not use force, swing the lamp with light movements or use pliers with a soft pad so as not to crush the glass.
| Type of lampshade mounting | Location | Tool | Action |
|---|---|---|---|
| Screw | Front or bottom | Screwdriver | Unscrew the screw, remove the ceiling |
| Latches (one) | Side | No | Press the lock, slide |
| Latches (two) | Top and bottom | No | Squeeze the sides, pull down |
| Friction landing | In the niche | Knife (carefully) | Pry up the edge, pull out |
What what to do if the lampshade cannot be removed?
If the lampshade cannot be removed, do not use brute force. Plastic becomes brittle at low temperatures. Try slightly warming the mounting location with a hairdryer at a minimum temperature for 10-15 seconds or wait until the refrigerator has completely thawed and warmed up to room temperature.
Installing a new light source
After the old element is dismantled, you can begin installing a new one. Get a new lamp and make sure it is dry and clean. Screw it into the cartridge clockwise until it stops, but without fanaticism. Excessive force can lead to destruction of the base or damage to the contacts inside the socket, which will require a more complex repair with disassembling the inner wall.
If you are using LED a lamp, check the polarity only if the base is specific, although this is usually not required in the E14/E27 standards - they operate on alternating current. Make sure that the lamp bulb does not touch the walls of the lampshade or the internal elements of the refrigerator if the design involves a tight fit.
Now you need to return the protective lampshade to its place. If it is screw-mounted, install the shade first and then tighten the screw. If using latches, align the slots and press until you hear an audible click. Make sure that the lampshade sits tightly and does not wobble, otherwise vibration from the operation of the compressor may eventually break contact or damage the lamp.
⚠️ Attention: Never plug in the refrigerator with an open lampshade or without a lamp, if the cartridge. Moisture and condensation can get onto the contacts, causing a short circuit or corrosion.
Checking the system functionality
After assembling the structure, the most crucial moment comes - testing. Plug in the refrigerator. Please note that in most models Biryusa the light comes on only when the door is open, since the circuit is closed through a limit switch (a button or sensor in the door opening). Therefore, the door must be opened.
If the light comes on smoothly, without blinking or extraneous crackling, then the replacement was successful. Close the door and listen: after a while the compressor should start. If the light does not light up, perhaps the problem is not in the lamp, but in the socket itself, the wiring or the limit switch. In this case, more in-depth diagnostics will be required.
It is also worth checking whether the ceiling heats up excessively during operation. Incandescent lamps produce a lot of heat, and if the wattage is set incorrectly (higher than recommended), the plastic may begin to deform. During the first hours of operation, periodically check the condition of the lamp by hand (carefully).
Possible problems and their solutions
Sometimes after replacing the lamp, users encounter unusual situations. For example, a new lamp burns out after a few hours or days. This may indicate voltage surges in the network or problems with the contacts in the cartridge. Oxidized contacts create increased resistance and heat, which is detrimental to the light source.
Another common problem is buzzing or crackling. Incandescent lamps are usually silent. If you hear a sound, this may be a sign of a bad connection in the base or a defect in the lamp itself. Low-quality LED lamps can emit a high-frequency squeak, which is especially audible in the silence of the kitchen at night.
The table below shows the malfunctions and methods for eliminating them:
- 💡 The lamp is flashing - check the screw-in tightness of the base.
- 💡 The light burns dimly - perhaps the voltage in the network is below normal or the contacts are oxidized.
- 💡 The lamp has broken inside the base - you need to carefully remove the remains of the base with pliers with the power off.
If you are faced with the fact that the lamp has broken and the base remains in the socket, do not panic. Unplug the refrigerator. Take a pair of pliers, grab the edge of the metal base and carefully unscrew it counterclockwise. If the base is smooth, you can try to cut out the remaining glass and carefully pry the edge of the base with a screwdriver, rotating it.
How to remove a broken base without tools?
If you don’t have pliers on hand, you can use a raw potato. Cut it in half and press the cut firmly against the protruding edges of the base, then gently rotate. The starch and density of the pulp will help to grab the metal and unscrew it.
Frequently asked questions about replacing lighting
Is it possible to put an LED lamp in the Biryusa refrigerator?
Yes, you can if it has an appropriate base (usually E14) and runs on 220V. However, make sure that the LED lamp is designed to operate at low temperatures, otherwise it may quickly fail or not light up in the cold.
Why is the light constantly on in the refrigerator?
Most often the reason is a stuck limit switch (button), which is located in the doorway. Also, the light may be on if the door is not tightly closed due to skewed hinges or a foreign object interfering with closing.
What is the maximum lamp power allowed for Biryusa?
It is recommended to use lamps with a power of no more than 15-25 watts. Using more powerful lamps can lead to overheating of the plastic lampshade and its deformation, as well as increased energy consumption.
What to do if the new lamp does not light up?
Check the tightness of the base. If this does not help, the socket, limit switch or wiring may be faulty. Try installing a known-good lamp in another device to prevent the lamp itself from being defective.
Do you need to defrost the refrigerator before replacing?
Full defrosting is not necessary if access to the lampshade is free. However, if the “fur coat” is frozen and interferes with access, or if you are afraid that condensation will get on the contacts, it is better to wait for defrosting or speed it up using safe methods.
