Sudden loss of light inside the refrigerator compartment is often takes you by surprise, especially when you need to quickly find products. In refrigerators Ariston Hotpoint, as in other equipment, this can be caused by a burnt-out incandescent light bulb or failure of the LED module. Replacing a light source yourself is a simple procedure that does not require calling a technician or special tools if you know the sequence of actions.
Before starting any work, de-energize the device. This is a critical step, as even low voltage in the lighting circuit can be dangerous if the wiring is shorted or mishandled. Unplug the plug from the socket and let the unit stand for a few minutes.
In this article we will look at how to properly dismantle the lampshade, remove the burnt part and install a new one without damaging the plastic elements of the case. We will also discuss what types of light bulbs are suitable for your model Hotpoint and what to look for when purchasing.
Preparing for work and choosing a lamp
Before you begin dismantling, you need to understand what type of light source is installed in your model. Refrigerators Ariston Hotpoint can be equipped with classic incandescent lamps with E14 base, halogen elements or modern LED panels. An error in choosing the type of lamp can lead to the fact that it simply will not fit or, in the worst case, damage the wiring.
Most often, 15 W incandescent lamps are used in budget and mid-range models. They get hot, but are cheap and available. More expensive series use halogen lampswhich shine brighter, but require careful installation - they cannot be touched with bare hands, as oil from the skin causes local overheating of the glass.
- 🔦 E14 incandescent lamp (15 W) - the standard option for most models.
- 💡 G4 halogen lamp - found in models with side lighting.
- 💡 LED module - non-removable board with LEDs that requires replacement entirely.
- 🛠️ Tools: flat screwdriver, soft cloth, gloves.
If you are not sure which lamp you need, it is best to unscrew the burnt one and take it with you to the store as a sample. Pay attention to the base markings and the voltage indicated on the glass. For modern electronically controlled refrigerators, it is important to observe polarity when it comes to LED assemblies.
⚠️ Attention: Never install a lamp with a higher power in the refrigerator than indicated in the instructions (usually 15 W). This will lead to melting of the plastic lampshade and may cause a fire in the wiring.
Removing the lampshade and accessing the lamp
Access to the light bulb in refrigerators Hotpoint is usually covered with a transparent or translucent plastic lampshade. The mounting design may vary depending on the model year. In older versions, the lampshade is held on by latches, in new ones it can be screwed on with a screw or simply inserted into the grooves.
First, carefully inspect the lampshade. If you see a hole for a screw, you need to unscrew it with a Phillips screwdriver. If there are no screws, then the system is being used hidden latches. Carefully pry up the edge of the lampshade with a flat-head screwdriver wrapped in a cloth to avoid scratching the plastic. Operate without sudden jerks.
Plastic becomes brittle at low temperatures, so if the refrigerator has just been working, let it warm up to room temperature before removing parts. This will reduce the risk of the mounting lugs breaking. The lampshade is removed by moving towards you or downwards, depending on the model.
☑️ Preparation for removing the lampshade
After removing the lampshade, access to the lamp base or LED board contacts will open. If the lamp has just been lit, it may be hot - use a cloth or gloves to remove. Visually inspect the contacts: they should not be oxidized or blackened.
The process of replacing the light source
Replacing an incandescent lamp or halogen element is done with a standard counterclockwise twisting motion. If the lamp is “stuck” in the base due to oxidation, do not use excessive force - it is better to use a special spray to clean the contacts or gently rock the base, gradually increasing the amplitude.
In the case of LED lighting the situation is more complicated. Often the LEDs are soldered onto a common board, which is attached to the refrigerator body with screws or latches. Here you will need to disconnect the power connector. It is important to remember the position of the wires or photograph the connection diagram before dismantling.
| Lamp type | Socket | Power | Service life |
|---|---|---|---|
| Incandescent | E14 | 15 W | ~1000 hours |
| Halogen | G4 | 20 W | ~2000 hours |
| LED panel | Fixed | 1-3 W | ~30,000 hours |
| LED module | Connector | 2-5 W | ~50,000 hours |
When installing a new lamp, avoid direct contact of your hands with the glass bulb, especially if it is halogen. Fatty traces will lead to uneven heating and rapid failure. If you accidentally touch the glass, wipe it with an alcohol wipe before installation.
Features of LED lighting in Hotpoint
Modern refrigerators Ariston Hotpoint are increasingly equipped with LED lighting systems. Their main advantage is energy efficiency and durability. However, if the LED burns out, the matter is not limited to simply replacing the light bulb - often it is necessary to change the entire LED unit or even the lighting control board.
Diagnostics of the LED system requires a multimeter. It is necessary to test the circuit for voltage when the refrigerator is turned on (observing safety precautions). If there is voltage at the input to the unit, but there is no light, the problem is in the module itself. If there is no voltage, the fault may be in the door switch or wiring.
Why is the LED lamp blinking?
Flashing LEDs in the refrigerator often indicate an unstable voltage in the network or a malfunction of the power driver inside the LED module. Also, the cause may be oxidation of the contacts in the connection connector.
When purchasing a replacement unit, pay attention to the dimensions and location of the mounting holes. There are few universal solutions, and a module from another model may not fit into its standard place. Look for the article number on the body of the burnt element.
Checking the door switch and wiring
If the new lamp does not light up, the problem may lie not in it, but in the control circuit. The main element that closes the circuit when the door is opened is limit switch (button). In refrigerators Hotpoint it is often located at the top of the chamber or on the side wall.
Over time, the switch contacts may oxidize or become stuck. Check its operation: press the button with your finger - you should hear a clear click. If the button moves tightly or does not return to its original position, it must be replaced or lubricated (if the design allows).
Also inspect the wiring going to the lamp. In older models, the wires could rub against the edge of the case or be damaged by rodents (if the refrigerator was in the garage). Any insulation damage requires immediate restoration using heat shrink or electrical tape.
⚠️ Attention: When checking a live switch, use tools with insulated handles. Do not touch the metal parts of the refrigerator body at the same time as live elements.
Assembly and final testing
After installing the new lamp and checking the contacts, you can begin assembly. Install the lampshade in place, making sure that all the latches fit into their grooves with a characteristic click. Do not use excessive force - if the plastic does not fit, it means you have chosen the wrong installation angle.
Plug in the refrigerator. The door must be open to activate the switch. If the light comes on immediately and burns evenly, without flickering, the procedure was successful. Close the door and listen: the light should go out and the compressor (if the time has come) should start.
Leave the refrigerator idling for about 30-40 minutes to make sure that the new lamp does not cause overheating in the lampshade area. Touch the plastic around the light source - it should not be hot, only slight warmth is allowed.
Possible problems and solutions
Sometimes after replacing the lamp the light still does not appear. This may indicate a more serious problem with the refrigerator's electronic control module. In models with the system No Frost a separate relay on the board may be responsible for lighting, which could burn out.
Another common problem is loose contact in the socket. The petals of the base may have separated or oxidized. Gently bend them with a screwdriver (be sure to turn off the refrigerator!) and clean with alcohol. This will restore contact and ensure stable operation of the lighting.
- 🔌 The light does not light - check the continuity of the circuit with a multimeter.
- 🔥 The lamp is heating up - replace the lamp with a less powerful one or LED.
- 💡 The light is blinking - the problem is in the driver or voltage network.
- 🔘 The button does not click - the limit switch needs to be replaced.
If you have tried all the methods, but the light does not appear, the main control unit may be faulty. In this case, self-repair requires deep knowledge of electronics and the availability of a circuit diagram for a specific device.
Is it possible to use an LED lamp instead of a regular one?
Yes, you can if the base matches (usually E14). However, regular household LED lamps may not work in electronically controlled refrigerators due to the circuitry. It is better to use specialized lamps for refrigerators or standard LED modules.
Why does the light bulb in an Ariston refrigerator burn out so often?
Frequent burnouts can be caused by power surges in the network, a malfunction of the door switch (sparking contacts) or the use of lamps of higher power than those provided by the design, which leads to overheating.
Where can I find the article number of the original lamp for Hotpoint?
The article number is usually indicated on the lamp itself (if it is intact) or in the technical documentation for the refrigerator. You can also find the part number on the websites of spare parts suppliers by entering the model of your refrigerator (for example, HFG 5181 W).
What to do if the glass of the lamp inside the refrigerator breaks?
Immediately turn off the refrigerator. Carefully remove the splinters and the base (using pliers and a potato tuber to wring out the remains). Vacuum the chamber thoroughly to prevent glass from getting into the ventilation system or onto food.
