Sudden darkness inside the refrigerator compartment Hotpoint Ariston often takes you by surprise when you need to urgently get products. This situation not only causes inconvenience, but also signals the need for an urgent replacement of the lighting fixture. Modern refrigerators of the Italian brand are equipped with reliable lighting, but the resource of any light source is not infinite.
The process of replacing a light bulb in models Hotpoint and Ariston (united under a single brand) usually does not require calling a technician or a specialized tool. It is enough to know the location of fasteners and follow basic electrical safety rules. In this article, we will analyze in detail the algorithm of actions, the types of lamps used and nuances that will help avoid damage to plastic parts.
Before starting any work, it is critically important to disconnect the refrigerator from the electrical network. Even if you are only changing the lampshade, the risk of a short circuit or electric shock from accidentally touching the contacts should be completely eliminated. Unplug the plug from the socket and begin diagnostics.
Diagnostics and selection of the type of light bulb
Before disassembling the lamp, you need to make sure that the problem lies in a burnt-out lamp, and not in a faulty wiring or door switch. Refrigerators Hotpoint Ariston most often use two types of light sources: classic incandescent lamps with an E14 base and modern light-emitting diode (LED) modules. You can determine the type visually, if the lamp is still shining, but blinking, or by the marking on the base, if it is visible.
If your model has a regular incandescent lamp, replacing it is trivial - just unscrew the old one and screw in a new one of similar power. However, in many new series, such as HF 8181 or HSB 9201, non-removable LED panels or lamps with specific connectors are used. In this case, simply replacing the “pear” will not help - you will need to replace the entire backlight module.
When buying a new lamp, pay attention to the dimensions. Even if the base matches (usually this is E14), the bulb itself may be wider than the standard one and will rest against the walls of the lampshade or the door when closed. The optimal power for the refrigerator compartment usually does not exceed 15 W for incandescent lamps, so as not to create excessive heat.
⚠️ Attention: Never use lamps with a power higher than that recommended by the manufacturer. The plastic of the ceiling in refrigerators Hotpoint can be deformed from high temperature, and excess heat will negatively affect the operation of the thermostat.
To accurately select a spare part, remove the burnt out element and take it with you to the store or take a photo of the marking. If you are planning on switching to LED analogues, make sure that they are designed specifically for refrigerators, since conventional LED lamps may not work correctly with the electronics of the refrigerator or have an unsuitable color temperature.
Necessary tools and preparation
Replacing a light bulb in a refrigerator Hotpoint Ariston is an operation that does not require complex equipment. However, having the right tool on hand will greatly speed up the process and reduce the risk of damaging the fragile plastic. The main task is to carefully remove the protective lamp, which is often secured with hidden latches.
You will need a flat-head screwdriver with a wide blade to pry out the plastic clips without leaving scratches. A knife with a wide blade (use extremely carefully) or a special plastic pick for opening cases may also be useful. Don't forget to prepare dry rags or gloves so as not to leave greasy marks on the inner walls of the chamber and the new lampshade.
- 🔦 Flashlight —indispensable, since after turning off the refrigerator the chamber will be dark, and looking for a light bulb by touch is inconvenient.
- 🪛 Flat screwdriver —preferably with a thin but durable sting for access to narrow fastening grooves.
- 🧤 Cotton gloves - will protect the new lamp from grease from your fingers, which is especially important for halogen light sources.
- 📏 Ruler or tape measure - to check the dimensions of the new lamp, if you change the type of lighting.
Prepare the workplace in advance. Clear space in front of the refrigerator so that nothing interferes with your view. If there are a lot of products in the chamber, it is better to temporarily put them in a cooler bag or on the balcony (in winter) so that they do not spoil while you are fiddling with the electrics.
☑️ Preparing to replace the light bulb
Removing the lighting lamp
The most important step is removing the protective lamp. In refrigerators Hotpoint Ariston the design of the lampshades may differ depending on the series. In some models (for example, the Indesit old model series), the lampshade is held on by one screw, in others - solely by latches. Carefully inspect the lamp body.
If you see a screw, it is usually hidden under a decorative plug or located in the center of the bottom of the diffuser. Unscrew it counterclockwise. If there are no screws, then the lampshade is held on by latches. They can be located in front, behind or on the sides of the plastic cover. Carefully pry up the edge of the lampshade with a flat screwdriver wrapped in fabric and press until you hear a characteristic click.
Do not use excessive force. Plastic becomes brittle at low temperatures, and sudden movement can cause a crack. Move sequentially: snap one side, then move to the opposite. In some models Ariston the lampshade must first be moved down and then pulled towards you.
After successful dismantling, inspect the insides. There you will see a lamp socket and possibly wires going to the door switch. Make sure that the cartridge contacts are not oxidized or have any traces of carbon deposits. If the plastic around the socket is blackened, the lamp may have gotten too hot and the entire backlight assembly will need to be replaced.
What to do if the lampshade is not removable?
If you cannot find the screws or latches and the lampshade does not budge, it may be attached to hidden guides. Try to carefully pull the entire lampshade assembly down (if the design allows) or move it to the side. In rare cases, in older models, the lampshade may be glued with sealant - then it needs to be carefully trimmed around the perimeter with a knife, but this is a last resort.
The process of replacing the light source
When access to the lamp is gained, the replacement procedure depends on its type. For a standard lamp with a base E14 everything is simple: unscrew the old one counterclockwise and screw in the new one. The main thing is not to overtighten the base, so as not to damage the thread of the cartridge. The lamp should fit tightly, but without effort.
If your Hotpoint Ariston has an LED board installed, the situation is more complicated. It can be attached with double-sided tape or small screws. If attached with tape, carefully pry the edge of the board with a knife and disconnect it. Then you need to unclip the wire connector. The new module is installed in the reverse order. It is important not to reverse the polarity when connecting, although in modern connectors Hotpoint this is difficult to do due to the shape of the connector.
When installing a new incandescent lamp, try not to touch the glass bulb with your bare hands. Grease stains from fingers when heated can lead to local overheating of the glass and rapid failure of the lamp. If touched, wipe the bulb with an alcohol wipe before installation.
After installing a new element, do not rush to put everything back together. Plug in the refrigerator for a short time to check the functionality of the new lamp. If the light comes on, great, turn off the power again and complete the assembly. If not, check the tightness of the base or the integrity of the contacts.
Table of compatibility and characteristics of lamps
For the convenience of selecting spare parts, below is a table with the main characteristics of lamps used in various models of refrigerators Hotpoint Ariston. Please note that overall dimensions may vary slightly depending on the lamp manufacturer.
| Lamp type | Socket | Power (W) | Dimensions (mm) | Application |
|---|---|---|---|---|
| Incandescent | E14 | 15 W | Ø26 x 60 | Standard models |
| Halogen | G4 | 20 W | Ø9 x 35 | Models with spot backlight |
| LED module | Connector | 2-4 W | varies | HF, HS series (new) |
| Luminescent | 2Pin | 9 W | Ø16 x 260 | Rarely, in large chambers |
When choosing analogues, be guided not only by the base, but also by the shape of the bulb. Elongated lamps may not fit into the ceiling niche. Critical: For electronically controlled refrigerators, it is preferable to use LED modules, since they do not create interference and heat up less, which prolongs the life of plastic parts.
If you have not found the original lamp Hotpoint, you can use analogues from manufacturers Osram, Philips or Camelion, observing the above parameters. The main thing is that the base matches and that the power is not exceeded.
Assembly and final check
After successfully replacing the light bulb and checking its functionality, the assembly stage begins. Place the lamp in place, following the snap sequence. Slide one side (usually the top or back) into the groove first, then gently press the opposite side until it clicks. If there was a screw, tighten it, but without fanaticism, so that the plastic does not crack.
Make sure that the backlight wires are not pressed by the edge of the lampshade and do not contact moving parts (if we are talking about a door). Plug in the refrigerator. Check how the light works when opening the door. Also pay attention to the tight fit of the lampshade - warm air from the room should not enter the chamber through the cracks, this can lead to the formation of condensation.
- ✅ Check the tightness of all edges of the lampshade.
- ✅ Make sure that the lamp does not wobble in the socket.
- ✅ Wipe the inner walls of the camera if there are fingerprints on them.
Now you can load the products back. If the light does not come on after reassembly, the problem may not be with the lamp, but with the door switch or wiring. In this case, a more in-depth diagnosis is required.
⚠️ Attention: If, after replacing the light bulb, the light in the refrigerator comes on, but does not go out when the door is closed, check the serviceability of the door switch. A constantly burning lamp will lead to an increase in the temperature inside the chamber and overload of the compressor.
Frequent problems and their solutions
Sometimes replacing the light bulb does not solve the problem of lack of light. In refrigerators Hotpoint Ariston there are several typical malfunctions associated with the lighting system. One of them is sticking or oxidation of the door switch contacts. It is located in the side wall of the chamber and is mechanically pressed by the door.
Another common problem is oxidation of the contacts in the lamp socket itself. Over time, sparking or moisture forms a coating there that prevents the passage of current. In this case, cleaning the contacts with fine sandpaper or a file (with the power off!) will help. It is also worth checking the integrity of the wires going from the switch to the socket - they could have frayed.
If you have a model with LED backlighting and an electronic control module, the absence of light may indicate a failure in the control board. In this case, independent repairs without special knowledge and equipment are not recommended. It is better to contact an authorized service center.
Remember that regularly replacing burnt-out lamps and using energy-efficient LED analogues extends the life of the refrigerator and saves energy. Monitor the condition of the lighting system, and your Hotpoint Ariston will delight you with bright light and cold for many years.
Is it possible to install a more powerful lamp?
Technically, it is possible to screw in a lamp of higher power (for example, 25 W instead of 15 W) if the base matches. However, this is strictly not recommended. The plastic of the lampshade may melt, and the heat from the lamp will throw off the thermostat settings, causing the refrigerator to work harder, which will increase energy consumption and wear on the compressor.
Is it possible to use an LED lamp instead of a regular one in a Hotpoint refrigerator?
Yes, you can, and even need it. LED lamps heat up less and consume less energy. The main thing is to choose the right base (usually E14) and make sure that the dimensions of the LED lamp allow it to fit under the lampshade. There are also special LED lamps for refrigerators that are resistant to vibrations and low temperatures.
Why does the light bulb in the refrigerator blink after replacement?
Blinking may indicate poor contact of the base in the socket, a malfunction of the door switch (the contacts burn and spark) or problems with the wiring. If an LED lamp is installed, it may blink due to incompatibility with the electronics of the refrigerator - in this case, try returning the incandescent lamp or buying a specialized LED for refrigeration equipment.
Where is the backlight fuse in Hotpoint Ariston?
In most household refrigerators Hotpoint Ariston separate There is no fuse specifically for the backlight circuit. The lamp is powered directly through the door switch. If there is no light at all (and the lamp is definitely working), the problem is most likely in the switch or a broken wire in the corrugation of the door.
How to remove the lampshade if it is cracked?
If the lampshade is cracked, you need to act even more carefully so that the fragments do not fall into the food or onto the evaporator. Cover the crack with tape before removing. Remove the lampshade, starting from the whole side, carefully unclipping the latches. It is better to immediately replace a cracked lampshade with a new one, since warm air will penetrate into the chamber through the cracks.
