When the light does not work in the refrigerator, it is very inconvenient to use it. You need to urgently get rid of the problem, and for this you will have to find the cause of the malfunction. What bulbs are installed in the refrigerator, how they work and why they fail, read the article.
Types of lighting in the refrigerator
Different brands of modern refrigerators install different lighting. Light fixtures in older models are also different. Before you start looking for damage, you need to understand the features of the camera lighting.
- In old refrigerators, most often used an incandescent lamp, which was located on the ceiling of the chamber.
The principle of operation is quite simple: next to the door there is a button button. Closing the refrigerator, you click on it, the lighting turns off, and vice versa. Plus incandescent lamps at an affordable price, however, the service life is only 1000 hours.
- Halogen lamps are similar in structure to the previous ones. They also emit heat during operation, but the light is brighter than that of incandescent lamps. With high light output, the device consumes a minimum of electricity.
- Luminescent lighting can be distinguished by cool white light. These lamps do not heat up during operation and last from 8,000 to 11,000 hours.
- LED lighting is used in modern refrigerators. This is the most economical and safest type. The lamps do not heat up, last up to 11 years, consume a minimum of electricity - from 15 to 40 watts. However, replacing them yourself is difficult.
The complexity of LED lighting is in its control. The easiest option is the start button described by yours. There may also be a relay or a microcontroller.
The location of the lights in the camera
Luminaires can change the location in the chamber depending on the make and model of the refrigerator.
- The lamp is attached to the side wall. This is the most common type of accommodation. It can be combined with start buttons and temperature sensors.
- The lamp is located on the top panel. Not too good placement, since the lower shelves are very poorly lit.
- The best location is on the back wall. The lamp does not overlap, illuminates the entire camera.
- A rather rare installation is on the visor. Not too successful, there is little light in the cell.
If the light in the refrigerator is off, then you need to look for the cause of the breakdown.
Why lighting doesn't work
When you open the refrigerator door, you may notice that the light does not light up or the lamp flashes frequently. The latter happens due to the voltage drop in the network. Therefore, it is recommended to install RCD machines on devices with high energy consumption.
Why there is no lighting, and what needs to be checked:
- Click the switch: there may be no electricity in the house.
- Inspect the power cord. Perhaps its insulation was damaged - replacement is required.
- Check that the outlet is working. To do this, connect another device to it. If it works, everything is okay with the outlet.
- Track the work. Does it turn on after some time? Maybe the malfunction lies in the refrigerator itself.
- The most likely option is that the light bulb in the refrigerator has burned out, so a replacement is needed.
- The cartridge or its contacts could also be damaged, which complicates independent repair.
If the diagnosis confirms that the cause is a lamp, replacing is simple.
Independent lamp replacement in refrigerators of different brands
Before replacing, look at what type of lamp you have, and also measure the base. In some models, the lamp is equipped with a ceiling, which must be removed first.
In the refrigerator "Samsung" and "Atlant"
These models are equipped with shades. To get to them, unplug the refrigerator.
- Remove the baskets and trays that interfere with the replacement.
- Unscrew and remove the screw securing the lampshade.
- Disconnect the wiring.
- Remove the protective tape, if provided.
- Unscrew and replace the bulb with a similar model.
For the brand "Indesit"
If the lamp burns out in the Indesit refrigerator, do this:
- Unscrew the mount on one side of the lampshade. In Indesit models, the ceiling is not completely removable.
- Move part of the lamp to the side to allow access to the lamp.
- Unscrew the burnt device and install a new one.
For refrigeration equipment of Stinol and Biryusa brands
Manufacturers decided not to fasten the ceiling with screws. Therefore, it is enough for you to press the ceiling on both sides. If the latches do not go away, release them with a flat screwdriver. Then unscrew the lamp and replace.
On some models, it installs LED lighting. Then the plafond is removed along with the electronic unit.
- Remove the cover by depressing the latches.
- Remove the mounting bolts.
- Disconnect the wiring and remove the unit.
- Replace in the reverse order.

Malfunction Prevention
Lighting in the refrigerator will last much longer if you follow simple rules:
- Control the humidity in the chamber. Drops of moisture, condensation damage electronic equipment. The contacts and wiring in the camera deteriorate.
- Connect the equipment only to a grounded outlet, through an RCD circuit breaker. This will help to avoid power surges.
- When buying a refrigerator, pay attention to the type of lighting. LED backlighting is the most reliable and durable.
As you can see, replacing the bulb is easy. Be attentive to your technique, follow the rules of operation and installation.
