Lighting in the refrigerator compartment is an element that we notice only when it stops working. In models Ariston, as in most modern household appliances, the light source is often hidden behind a plastic diffuser, which in everyday life is called a lampshade. The need to remove it arises not only when a light bulb burns out, but also during general cleaning or replacing a failed LED.
Many owners are afraid to proceed with dismantling for fear of breaking the fragile plastic or damaging the internal wiring. However, the design of the lampshade is Ariston refrigerators thought out in such a way as to provide access to the lamp without the use of complex tools. The main thing here is understanding the principle of fastening and observing safety precautions.
In this article we will analyze in detail the process of removing the lampshade, consider the different types of fastenings found in different series of equipment, and give advice on replacing the light source. The right approach will allow you to avoid unnecessary expenses on calling a technician and extend the life of the lighting element.
Preparation for dismantling and safety measures
Before proceeding with any manipulations with the electrical components of the refrigerator, it is necessary to ensure the safety of the process. Despite the fact that the voltage in the network is household, the risk of a short circuit or electric shock in the presence of moisture or damaged insulation cannot be excluded. Disconnecting the device from the power supply is the first and mandatory action.
Unplug the power cord from the outlet. If the refrigerator is built into a kitchen unit, access to the outlet may be difficult, so it is better to provide in advance the possibility of quickly disconnecting the power. After disconnecting, let the device stand for a couple of minutes so that the capacitors on the control boards (if they are in the lighting circuit) are discharged.
⚠️ Attention: Never try to remove the lampshade or replace the lamp while the refrigerator is plugged in. Even if the lamp is not lit, voltage may remain on the contacts, which is life-threatening.
You may need a minimum set of tools to work. In most cases, a flathead screwdriver with a thin blade will be sufficient. Sometimes it is useful to have a multimeter on hand to check the continuity of the circuit if replacing the light bulb does not solve the problem of no light. Also prepare a new lamp or LED module that matches the characteristics of your Ariston.

Determining the type of mounting of the lampshade
Design of the lampshade in refrigerators Ariston may vary depending on the year of manufacture of the model and series. Understanding the type of fastening is the key to successful disassembly without damage. In old and budget models, a threaded connection is often found, while in modern units latches dominate.
Carefully inspect the diffuser. If you see a plastic nut with grooved edges in the center or on the side, it means you have a threaded type of fastening. This nut is usually unscrewed counterclockwise. In some cases, the nut may be hidden by a decorative plug, which must be carefully pryed off with a knife or screwdriver.
If there are no visible nuts, and the lampshade is a smooth plastic panel, most likely it is held on by latches. Plastic clamps can be located around the perimeter or concentrated in one part of the body. You can determine their location by lightly (without fanaticism) pressing on different parts of the lampshade and trying to turn or move it.
There is also a combined type of fastening, where the lampshade must first be turned to release the guides, and only then pulled down. Incorrect application of force in the wrong direction is guaranteed to lead to breakage of the fastening ears.
Removing the lampshade with a threaded fastening
This type of fastening is considered the most reliable and easiest to maintain. Most often, the threaded bushing is located in the center of the lampshade or offset to the rear wall of the refrigerator compartment. To remove, you do not need a complex tool, just your fingers or, in case of tightness, soft-nose pliers.
Grab the knurled part of the nut and start rotating it counterclockwise. Don't try too hard. If the nut does not budge, it may have become stuck due to changes in temperature and humidity. In this case, you can slightly heat the plastic element with a hairdryer at the minimum temperature, but be careful not to melt the plastic.
After the nut is completely unscrewed, carefully remove it. The shade is now free and should come off easily. If it fits tightly, the edges may be caught in the grooves of the housing. A slight rocking from side to side will help release the diffuser.
Inside you will see the lamp base and the wires suitable for it. Pay attention to the condition of the wire insulation. If the plastic has become brittle or cracked, replacing the lampshade it is better to do it entirely, since the old material may crumble when reinstalled.
Removing the lampshade with latches and clamps
Modern refrigerators Ariston are often equipped with lampshades with latches. This makes the design more aesthetically pleasing, but requires some skill when disassembling. The main mistake users make is trying to pick out the lampshade from one corner, which leads to broken ears.
Find the place where the fixing tab is located. Often it is located on the side opposite the door hinges, or at the top of the ceiling. Carefully insert a flat-head screwdriver wrapped in fabric (so as not to scratch the plastic) into the gap between the lampshade and the body.
Press the latch lightly and at the same time pull the lampshade down or towards you, depending on the design. You should hear a characteristic click. After the first latch has disengaged, do not pull sharply - there may be other latches. Walk around the perimeter and carefully snap them off.
⚠️ Attention: Plastic becomes very brittle at low temperatures. If you have just defrosted the refrigerator, wait 10-15 minutes for it to warm up to room temperature, otherwise the risk of breaking the latch during removal increases many times over.
In some models, the lampshade must first be moved to the side (left or right) to disengage it from the guides, and only then pulled down. Carefully study the design: if you see longitudinal grooves, then the movement should be progressive.
Replacing the light source and checking the contacts
After successfully removing the lampshade, access to the lamp opens. Older models Ariston use standard incandescent lamps with an E14 base, while new ones use LED modules or halogen lamps. Before installing a new element, make sure that its power and dimensions meet the manufacturer’s requirements.
Unscrew the burnt-out lamp (if it is threaded) or disconnect the connector (if it is an LED module). Inspect the connector base or pins. If you notice oxidation or traces of carbon deposits, carefully remove them with an eraser or alcohol. Poor contact is a common cause of flickering or premature failure of new lamps.
Install a new light source. If you are replacing an incandescent bulb with an LED bulb, make sure the base matches. LED lamps heat up less and consume less energy, which is a plus for the refrigerator compressor.
Check the functionality of the system before final assembly. Plug in the refrigerator (being careful with the wires!) and close the contacts of the door sensor (or simply press the button/lever for turning on the light, if there is one separately). If the light comes on, you can turn off the power to the device and complete the assembly.
Why does a new lamp burn out immediately after installation?
A common reason is a voltage surge at the moment of switching on or poor contact in the socket. It is also possible that the cartridge itself is faulty (the contacts are burnt) or there is a problem with the thermostat, which supplies current constantly, even when the door is closed. Check the mains voltage and the condition of the cartridge.
Comparison of lamp types for Ariston refrigerators
Choosing the right lamp is not just a matter of base. Different types of light sources have their own characteristics of operation, heat transfer and service life. Below is a table to help you navigate the types of lamps used in refrigerators Ariston.
| Lamp type | Case | Service life (hours) | Heat dissipation | Features |
|---|---|---|---|---|
| Incandescent | E14 / E27 | 1000 | High | Cheap, but heats the camera |
| Halogen | G4 / G9 | 2000-4000 | Medium | Bright light, afraid of touching hands |
| LED | E14 / Built-in | 30000+ | Low | Economical, durable |
| Luminescent | Special. connector | 8000-10000 | Low | Found in older models |
When replacing an incandescent lamp with an LED one, remember that LED lamps are polarity sensitive if they are connected through a driver, but regular base LED lamps (12V or 220V) work regardless of polarity connections. However, if you are changing the built-in LED module, it is important to follow the markings of the wires.
Do not use lamps with a higher power than indicated in the instructions (usually up to 15 W for incandescent lamps). Exceeding the power will lead to melting of the lampshade and socket, as well as to increased load on the cooling system.
Assembly and final inspection
Assembly is done in reverse order. Make sure that the rubber seal (if there is one between the lampshade and the body) is in place and is not twisted. This is important for tightness and protection from moisture. Insert the lampshade into the grooves, press until it clicks (for latches) or tighten the nut (for a threaded connection).
Do not overtighten the threads. Plastic is a viscous material, and excessive force can cause the thread to simply break off after several compression-expansion cycles. Tighten all the way by hand, without using tools.
After installation, turn on the refrigerator. Check whether the light comes on when the door is opened and goes off when closed. If a button is used, check its operation. Make sure that the lampshade does not wobble and sits tightly.
During the first 24 hours, observe the operation of the refrigerator. If you notice a smell of burning plastic or the lampshade begins to heat up (check carefully with your hand), immediately turn off the power to the device. This may indicate improper installation or the use of a lamp of inappropriate power.
⚠️ Attention: If after replacement the lamp is constantly on, even when the door is closed, check the serviceability of the door sensor. A stuck sensor will cause the light to remain on continuously, heating the chamber and causing the compressor to work without interruption.
Frequently asked questions (FAQ)
Is it possible to use a regular household lamp instead of a special one for the refrigerator?
Technically, if the base matches (usually E14), the lamp will screw in and shine. However, conventional lamps are not designed to operate in conditions of high humidity and low temperatures, as well as constant vibration of the compressor. Special refrigeration lamps have a reinforced design of the bulb and contacts. Using a regular lamp is acceptable as a temporary measure, but it is better to install a specialized analogue.
Why is the light flickering in the Ariston refrigerator?
Flickering can be caused by several reasons: poor contact in the socket (oxidation), a malfunction of the lamp itself (especially if it is an LED with a low-quality driver) or problems with the door sensor. It is also worth checking the voltage in the network - strong surges can cause a strobe effect.
Where can I find the markings for ordering a new lampshade?
The lampshade article number is usually indicated on the inside of the diffuser itself or on a sticker next to the lamp. If the marking is erased, look for the model number of your refrigerator (located on the inner wall of the chamber or on the back panel) and contact the service center Ariston with a request for spare parts according to the model.
What to do if the lamp latch is broken?
If the plastic ear breaks off, fixing broken. Temporarily, you can use a drop of safe glue (not superglue, which releases fumes) or place a piece of foam/rubber to create pressure. However, it is safest to order a new assembled lampshade, since a repaired one may fall out due to vibration.
Is it safe to leave the refrigerator without a lampshade for a while?
For a short time (several hours) - yes, if you urgently need to cool food, but the lampshade is broken. However, use without a lampshade is not recommended: plastic protects the lamp from splashes and condensation. Moisture getting on a hot lamp can cause its destruction or short circuit.
