Suddenly the light going out inside the refrigerator often becomes an unpleasant surprise, especially when you urgently need to find food. Equipment owners Biryusa face this problem regularly, since the life of incandescent lamps, which are often installed at the factory, is limited. Fortunately, replacing a burnt-out lighting element is one of the simplest procedures available even to an inexperienced user, which does not require calling a technician.
Before taking active steps, you need to understand that you are dealing with electrical applianceoperating from a 220 volt network. Although the voltage inside the chamber is low, compliance with basic safety regulations is a prerequisite for starting any work. Ignoring this step may result in electric shock or damage to the electronic control module of the refrigerator.
In this article we will analyze in detail all the nuances of the process: from preparing tools to checking the functionality of a new lamp. You will learn how to carefully remove the lampshade without damaging the plastic latches, and what type of base is used in different models Biryusa. The correct approach will extend the life of the new lighting element.
⚠️ Attention: If after replacing the lamp the light still does not light up, the problem may lie in a faulty door switch or wiring. In this case, self-repair requires a multimeter and electrical skills.
Preparation of the workplace and necessary tools
Successful completion of the task does not require complex professional tools. In most cases, whatever is found in any DIYer's odds and ends drawer is sufficient. However, having the right tools will greatly simplify the process and reduce the risk of damaging the fragile plastic parts of the refrigerator interior.
The main tool will be a flat-head screwdriver. Its tip width should be sufficient to carefully pry off the edges of the lampshade, but not too wide so as not to scratch the plastic or the inner wall of the chamber. If you have a set of plastic mounting spatulas, it is better to use them - they are guaranteed not to leave marks on glossy surfaces.
- 🔦 Flashlight or headlamp - the light in the camera has gone out, so an external light source is required for comfortable work.
- 🪛 Flat-head screwdriver - necessary for carefully opening the protective casing lamps.
- 🧤 Cotton gloves - protect your hands from possible cuts if the lamp bulb bursts, and prevent grease from getting on the glass of the new light bulb.
- 🧼 Dry rags - useful for wiping the lampshade from dust and condensation before installation.
It is also important to prepare yourself in advance replacement lamp. Older models Biryusa often use incandescent lamps with an E14 base, while more modern ones use LED elements. Check in advance the type of base and power so as not to waste time going to the store twice.
☑️ Readiness to replace the lamp
Ensuring electrical safety during work
Although replacing a light bulb seems like a trivial task, electric current is unforgiving. A refrigerator is a device with a metal casing, which in the event of an insulation breakdown may become energized. Therefore, the first and most important rule is: any manipulations with internal components are carried out only after the device is completely disconnected from the power supply.
It is not enough to simply turn off the refrigerator with a button or temperature regulator. You must physically unplug the power cord from the outlet. This ensures that the moment you touch the contacts of the cartridge or metal fittings, the circuit is guaranteed to be broken. Even a short-term short circuit can damage the thermostat or electronic control unit.
If the socket into which the refrigerator is plugged in is located in a hard-to-reach place and it is impossible to immediately remove the plug, try to turn off the power through the circuit breaker in the panel. This is especially true for built-in models Biryusawhere access to the rear is often limited by furniture.
⚠️ Warning: Never rely on the refrigerator door to open the lighting circuit. The door switch may be faulty or stuck in the “on” position, leaving the contacts under voltage.
Removing the lampshade and accessing the lamp
The design of the lampshade in refrigerators Biryusa may vary slightly depending on the year of manufacture and the specific series of the device. However, the mounting principle remains the same: the plastic diffuser is held on by latches or one screw. Your task is to open it without breaking the fragile latches.
In most models, the lampshade is located on the back wall of the refrigerator compartment or in the upper corner. Inspect the diffuser body. If you see a hole for a screw, it needs to be removed. If there are no screws, then the lampshade is held on by latches. Find the technological groove, usually it is located on the end side or below.
Carefully insert the tip of a flat-head screwdriver into the groove and with a slight turning movement, unclip the latch. Don't try too hard. If the plastic does not give in, try prying on the opposite side. Often the latches are located on the sides, and they need to be released simultaneously or sequentially.
- 🔍 Visual inspection - find the junction of the ceiling and the refrigerator body.
- 🛠️ Careful opening - use a screwdriver as a lever, and not as a wedge, so as not to break through the plastic.
- ❄️ Caution at low temperatures - if the refrigerator has just been running, the plastic may be cold and more brittle, act more gently.
After the latches are released, the shade should come off easily. If it is stuck due to ice or dirt, do not pull sharply. Gently rocking from side to side will help release the fasteners. Now you have access to the lamp base and socket.
What to do if the lampshade is cracked?
If the plastic diffuser bursts during removal, do not despair. You can temporarily use the refrigerator without it, but be careful not to get any splinters into your food. You can order a new lampshade using the catalog number of your Biryusa refrigerator model at service centers or spare parts stores. This is an inexpensive part, and replacing it does not require special skills.
Selecting a suitable replacement lamp
It is critical to install a lamp with the correct characteristics. Using a light source that is too powerful can lead to melting of the plastic of the lampshade and deformation of the interior of the camera due to heat. The standard power for refrigerators Biryusa usually is 15 W, less often - up to 25 W.
The most common type of base is E14 (minion). This is a smaller version of the standard base. Before buying a new lamp, be sure to unscrew the old one and compare the sizes. Also pay attention to the dimensions of the bulb itself: it should not rest against the walls of the lampshade or shelf.
LED analogues are a modern alternative to incandescent lamps. They practically do not heat up, which is safe for food and plastic parts, and consume less energy. However, when choosing an LED lamp, make sure that it is designed to work in low temperature conditions and has an appropriate protection class.
| Parameter | Incandescent lamp | LED | Halogen |
|---|---|---|---|
| Power | 15-25 W | 1-3 W | 10-20 W |
| Heating | High | Minimum | Very high |
| Service life | 1000 hours | 15000+ hours | 2000-4000 hours |
| Price | Low | Medium/High | Average |
When purchasing, pay attention to the labeling. If it says 220-240Von the base of an old lamp, it means it is designed for direct connection to the network. There are also low-voltage lamps, but in refrigerators Biryusa they are extremely rare, usually in combination with a transformer.
The process of installing a new one lighting element
After the old lamp is unscrewed, carefully inspect the socket. There should be no traces of burning, oxidation or melted plastic inside. If the contacts look black or deformed, simply replacing the lamp may not solve the problem - you will need to replace the socket itself.
Handle the new lamp only by the base or through a dry cloth/glove. Greasy fingerprints on the glass when heated can lead to local overheating and rapid failure of the lamp. This is especially true for halogen and some types of incandescent lamps.
Carefully screw the new lamp into the socket clockwise. Do not tighten it all the way with excessive force - the ceramic of the cartridge may crack. Enough tight contact. After this, you can begin assembling the structure in the reverse order.
- 🔌 Checking the contacts - make sure that the central contact of the socket is slightly springy.
- 🔩 Screwing - rotate the lamp smoothly, without jerking.
- 🧹 Cleaning - while the lampshade is removed, wipe it from the inside with soft fabric for better light transmission.
Install the lampshade in place until the latches characteristically click. Make sure it fits snugly and doesn't wobble. Now you can turn on the refrigerator and check the result of your work.
Diagnostics and common problems
There are situations when replacing the lamp does not bring results: the light in the camera does not light up. In this case, the reason lies deeper. The first suspect is the door switch. This is a mechanical or magnetic sensor that closes the circuit only when the door is open.
To test the switch, open the refrigerator door and press the button (or simulate closing with a magnet if the sensor is a reed switch). If the light comes on when pressed, it means the system is working. If not, the contacts may be stuck or the wire may be broken.
It is also worth checking the integrity of the wiring. In old refrigerators Biryusa the wires could rub against sharp metal edges or dry out over time. Visual inspection of accessible sections of the circuit often helps to find a break.
⚠️ Attention: Diagnosing an energized electrical circuit is dangerous. If you do not have the skills to work with a multimeter, limit yourself to replacing the lamp. For further repairs, invite a qualified specialist.
Recommendations for caring for the lighting system
In order for the lighting system to serve for a long time, it is important to monitor the condition of the door seals. If the rubber is worn out and does not fit tightly, warm, moist air enters the chamber. This leads to increased formation of condensation and ice, which can short-circuit contacts or damage the cartridge.
Regular defrosting of the refrigerator also extends the life of all its components, including lighting. A thick layer of ice on the back wall can mechanically put pressure on the lampshade or dislodge the wires. Make sure that food does not touch the back wall and does not block the light.
When washing the refrigerator, avoid using aggressive chemicals and large amounts of water in the lampshade area. Liquid can flow inside the cartridge and cause corrosion of the contacts or a short circuit the next time you turn it on.
Following these simple operating rules will allow you to forget about problems with light for a long time. Proper care of equipment Biryusa is the key to its long-lasting and efficient operation.
Is it possible to use an LED lamp instead of a regular one?
Yes, it is possible and even necessary. Light-emitting diode (LED) lamps with E14 socket are an excellent replacement for incandescent lamps. They consume less energy, do not heat up the interior of the refrigerator and last many times longer. The main thing is to choose models designed to operate at low temperatures.
Why does the light bulb in the refrigerator constantly burn out?
Frequent burnout can be caused by voltage surges in the network, poor contact in the socket (sparking), using a lamp with a higher power than allowed, or vibration of the compressor, which destroys the filament. Also, the cause may be a faulty door switch that creates current surges.
Where can I find the marking of the Biryusa refrigerator model?
A technical passport or nameplate with the model number is usually on the inner wall of the refrigerator compartment (right or left), on the back wall of the case or on the base at the bottom in front. The recommended lamp power may also be indicated there.
What to do if the lampshade cannot be removed?
Do not use force. Perhaps the lampshade is additionally secured with a screw, which is hidden by a decorative plug, or it is frozen due to ice. Try slightly warming the plastic element with a hairdryer (not with hot air, so as not to melt it) or defrost the refrigerator completely.
