Interior lighting of the refrigerator Bosch - it would seem like a small thing, but without it it is difficult to imagine comfortable use of the equipment. A light bulb fails infrequently, but when this happens, many are faced with the question: which model to buy so that it matches the base, voltage and brightness? An error in choice can lead to overheating, flickering or even damage to the electronics of the refrigerator.
In this article we will look at what types of lamps are used Bosch in different series of refrigerators (from budget KIN86 to premium Serie 8), how to determine a suitable replacement by marking, as well as We'll give you step-by-step instructions for safe installation. We will pay special attention to modern LED analogues - they are more energy efficient, but not all models are compatible with the electronics of old refrigerators.
If your light bulb stops burning, do not rush to buy the first one you come across in the store. Next, you will find out why it is important to consider not only the base, but also the operating voltage, as well as how to avoid typical mistakes when replacing.
Types of lamps in Bosch refrigerators: from halogen to LED
Manufacturer Bosch uses three main types of lamps for interior lighting:
- 💡 Incandescent lamps —an outdated version, found in models before 2010 (for example, KGN39XL20). Power is usually 15–25 W, base
E14orE10. - 🔆 Halogen lamps - brighter and more durable, common in refrigerators of 2010–2018 (KIN86AF30, KAN58A55). A typical base is
G4orGY6.35, voltage 12 V. - 💎 LED lamps - a modern solution for models after 2018 (Serie 6/8, KIN87AF30). Base
G4orGU5.3, voltage 12–24 V, consumption up to 3 W.
Important: in electronically controlled refrigerators (display, touch buttons) the use of unsuitable lamps may cause malfunction of the control module. For example, an LED lamp with a driver that is incompatible with the refrigerator's power supply can lead to flickering or complete lighting failure.
How to determine the type of lamp in your model? Look at the technical data sheet (section Technical characteristics → Lighting) or use the compatibility table below.
Lamp compatibility table for popular Bosch models
| Refrigerator model | Year of manufacture | Lamp type | Case | Voltage, V | Power, W |
|---|---|---|---|---|---|
| KGN39XL20, KGN39XW20 | 2008–2012 | Incandescent lamp | E14 |
230 | 25 |
| KIN86AF30, KAN58A55 | 2013–2017 | Halogen | G4 |
12 | 10–20 |
| KIN87AF30, KAN92VI30 | 2018–2022 | LED | G4 |
12 | 1–3 |
| Serie 8 (KAG96AIP0) | 2020–2026 | LED (built-in) | GU5.3 |
24 | 2 |
Refrigerators of the Serie 8 series after 2022 often use non-removable LED modules, which, if they fail, require replacement of the entire lighting unit (article number 00644436 for models KAG96AIP0 i KAN92VI35).
⚠️ Attention: If your refrigerator is released until 2015 and is equipped with an incandescent lamp do not replace it with an LED without checking compatibility. In older models, the power supply may not support low-voltage LEDs, which will lead to their instant burnout.
How to determine the base and parameters of the lamp in your refrigerator
If you did not find your model in the table or lost the documentation, you can determine the base and type of lamp yourself:
- Disconnect the refrigerator from the mains and wait for complete defrosting (if required).
- Remove the protective lamp shade - it is usually attached on latches or screws (a Phillips screwdriver is required).
- Look at the markings on the bulb or base. For example:
- 🔍
E14 25W 230V—incandescent lamp, baseE14, power 25 W. - 🔍
G4 12V 20W—halogen lamp, baseG4, voltage 12 V.
- 🔍
- 📏
E14— 14 mm. - 📏
G4—distance between pins 4 mm.
For accuracy, take a photo of the lamp and base - this will help the store salesperson find an analogue. If the lamp is broken, pay attention to the socket: in refrigerators Bosch it is usually plastic with metal contacts.

Is it possible to replace the lamp incandescent to LED: risks and solutions
Many owners of old refrigerators Bosch want to switch to LED lighting because of its efficiency and durability. However, there are several nuances:
- ⚡ Supply voltage: Incandescent lamps in older models are designed for 230 V, and LEDs are usually 12 V. Connecting LEDs directly. will lead to its combustion. The solution is to use step-down transformer (for example, Electronic Transformer 12V 20W).
- 🔌 Dimmer compatible: In refrigerators with adjustable brightness (for example, KAN58A55) LED lamp may flicker. You need a model marked
dimmable. - 🔄 Polarity: LED lamps with a base
G4are polarity sensitive. If the lamp does not light after replacing, try turning it over in the socket.
For refrigerators Bosch 2015–2018 (for example, KIN86AF30) LED lamps are suitable G4 12V with a driver built into the base. Examples of compatible ones. models:
- 💡 Osram LED Star G4 1.5W 12V (article
4058075035596). - 💡 Philips LED G4 2W 12V (article
929001146601).
⚠️ Attention: In refrigerators with inverter compressor (series Serie 6/8) the use of non-original LED lamps may cause interference with operation electronics. If after replacement there are strange sounds or errors on the display, return the old lamp and contact the service center.
Step-by-step instructions for replacing the lamp in a Bosch refrigerator
Replacing the lamp is a simple procedure, but requires care. Follow the instructions to avoid damage to the socket or electronics:
- Disconnect the refrigerator from the mains and wait 10-15 minutes (if the lamp is halogen, it may be hot).
- Remove the lampshade:
- In most models (KIN86, KAN58) it is secured with latches - carefully pry it off from the side with a flat screwdriver.
- In premium series (Serie 8) the lampshade may be on screws - use a Phillips screwdriver.
- For the base
E14/E10: turn counterclockwise. - For the base
G4/GU5.3: pull it towards you (do not twist!). - Install a new lamp, observing the polarity (for LED).
- Return the lampshade to its place and check the lighting operation.
If after replacement, the lamp does not light:
- 🔌 Check whether it is tightly inserted into the socket.
- 🔋 Make sure that the refrigerator is connected to the network and the door is closed (in some models, the lighting turns on only when the door is open).
- 🛠️ If the lamp is working, but does not work, the socket or power supply may be faulty - diagnostics are required.
What to do if the lamp is on, but flickers?
Flickering of the LED lamp in a Bosch refrigerator is usually associated with driver incompatibility or low quality power supply. Try:
1. Replace the lamp with a model marked "anti-flicker".
2. Install a voltage stabilizer (for example, Mean Well LRS-35-12).
3. If flickering appears after replacing it with LED, return the halogen lamp and contact the service to check the electronics.
Where to buy a lamp for a Bosch refrigerator: original vs analogues
Original lamps Bosch can be found in branded service centers or on spare parts websites (for example, Bosch Service, EuronicsHowever, their price is often inflated - for example, an original LED lamp 00644436 costs ~1,500 rubles, while an analogue from Osram will cost 300–500 ₽.
Where to look for high-quality analogues:
- 🛒 Electronics stores: Leroy Merlin, Obi (section "Lamps for household appliances").
- 🌍 Online platforms: Wildberries, Ozon (search by filter "For refrigerators" + base).
- 🔧 Service centers: often sell spare parts from warehouses (for example, lamps
G4 12Vfor Bosch).
When choosing an analogue, pay attention to:
- 🔍 Socket —must match the original.
- ⚡ Voltage — 12 V for halogen/LED, 230 V for lamps incandescent.
- 💡 Power —do not exceed the original (for example, if it was 20 W, do not take 30 W).
- 🎨 Color temperature —optimally 2700–3000K (warm white).
⚠️ Attention: When buying a lamp in the markets or from unverified sellers, you risk running into a fake. Low-quality LED lamps can overheat and melt the socket. Check the certificates of conformity (signPCTorEAC).
Common mistakes when replacing a lamp and how to avoid them
Even such a simple procedure as replacing a lamp can result in problems if you do not take into account key points. Here are the most common mistakes:
- Ignoring voltage: Installing a 230 V lamp into a 12 V socket (or vice versa). The result is an instant burnout or short circuit.
How avoid: Always check the markings on the socket or in the refrigerator passport.
- Use of force when removing the lamp: Sockets
G4andGU5.3are fragile - if you pull too hard, you can break the pins.How to avoid: Gently rock the lamp left and right before removing.
- Using lamps with inappropriate color temperature: Cold white light (5000K+) distorts the colors of products and irritates the eyes.
How to avoid: Choose lamps with a temperature 2700–4000K.
- Forget about the polarity of LED lamps: If the lamp does not light, it needs to be turned over in the socket.
How to avoid: Mark with a marker the correct position at the first installation.
Another typical problem is poor contact in cartridgeIf the lamp flashes periodically or dims, clean the socket contacts with alcohol and carefully bend them with a screwdriver.
FAQ: Answers to frequently asked questions about lamps in Bosch refrigerators
Is it possible to use a lamp with a higher power than that? original?
No. Exceeding the power leads to overheating of the cartridge and the risk of melting of plastic parts. For example, if there was a 15 W lamp in the refrigerator, it is not recommended to install 25 W. An exception is replacing an incandescent lamp with an LED: the power may be lower (for example, 3 W instead of 20 W), but the luminous flux should be comparable.
Why does the new LED lamp burn dimly or flicker?
This is due to the incompatibility of the lamp driver and the refrigerator's power supply. Solutions:
- Replace the lamp with a model marked
dimmable(adjustable). - Install a voltage stabilizer between the socket and the lamp.
- Return to a halogen lamp if the problem is not solved.
What is the service life of the lamps in a Bosch refrigerator?
Depends on the type:
- 💡 Incandescent lamps: 1,000–2,000 hours (~1–2 years at average load).
- 🔆 Halogen: 2,000–4,000 hours (~2–4 years).
- 💎 LED: up to 25,000 hours (~10 years), but the actual period depends on the quality of the driver.
Frequently opening the door shortens the service life due to temperature changes.
What to do if the refrigerator does not turn on after replacing the lamp?
Probable reasons:
- Short short circuit during installation - check the fuse (usually located on the compressor).
- Incorrect lamp voltage - remove it and turn on the refrigerator without lighting.
- Damage to the cartridge - inspect the contacts for melting.
If the refrigerator does not start, disconnect it from the network and call technicians.
Is it possible to replace the lamp yourself if the refrigerator is under warranty?
Yes, replacing the lamp does not apply to warranty cases, since it is a consumable item. However, if you damage the socket or electrical wiring during the replacement, the warranty for these components will be lost. Advice: take a photo of the disassembly process to return everything to its place.
