Sudden dimming or complete absence of light inside the refrigerator compartment often takes you by surprise, forcing the home cook to guess about the state of the products when she turns on the smartphone’s flashlight. If you are the owner of brand equipment Aristonthen the procedure for replacing a lighting element, as a rule, does not require calling a specialist and having a complex tool. Understanding the design of your unit will allow you to carry out manipulations in a few minutes, restoring the comfort of using the device.
However, before you begin dismantling, you must be clearly aware that you are working with an electrical device connected to the network. Despite the low voltage in the backlight circuit, the risk of electric shock or short circuit due to careless handling of the wires remains. In this article, we will analyze in detail the algorithm of actions for various models so that you can safely perform a replacement.
It is also important to consider that the design of the lampshades may differ depending on the year of manufacture and series of your refrigerator. Some models are equipped with simple latches, others require unscrewing screws, and others use a combined fastening method. Let's look at the main stages of preparation and direct removal of the part.
Preparation for work and safety measures
The first and most critical stage of any operation with household appliances is the complete de-energization of the device. You need to unplug the power cord from the outlet, not just turn off the button on the control panel. This action ensures that when you touch the contacts or metal parts of the base, you will not get an electric shock, even if the wire insulation is damaged.
After disconnecting, let the equipment stand for a while, especially if it was working intensively. This is necessary not only to stabilize temperatures, but also to make the plastic parts less fragile. In the cold, some types of plastics can crack under careless pressure, so temperature adaptation materials play an important role.
Prepare your workplace: you may need a stepladder or a stable chair if the light bulb is located high. Also, stock up in advance with a dry rag to wipe the lampshade from condensation and dust that may have accumulated there over the years of operation.
⚠️ Attention: Never carry out work on replacing electrical equipment with wet hands or standing on a wet floor. Even a low-voltage 12-24V circuit in combination with water can cause an unpleasant electric shock or damage to the electronics of the refrigerator.
Check for a new lamp in advance. In most cases, refrigerators Ariston use standard sockets, but it is better to ensure compatibility before disassembling so as not to leave the refrigerator open for a long time.
☑️ Preparing to replace the lamp
Determining the type of base and power
Before removing the old light bulb, you need to understand what type of lighting element is installed in your model. An erroneous attempt to screw in the wrong part may result in damage to the socket or the lamp itself. In refrigeration technology, two main types of bases are most often found, and they are easy to distinguish visually.
The most common option is the base E14, known in everyday life as a “minion”. This is a smaller version of the standard threaded base often used in chandeliers. If your lamp is screwed into a thread, then with a 99% probability it is type E14. The power of such lamps usually does not exceed 15-25 Watts, which is important for maintaining temperature conditions.
The second option, which is found in more modern or specific models Ariston, are tubular lamps or elements with a pin base. They may look like small glass bulbs with two contacts at the ends. Such lamps do not unscrew, but are pulled out or removed by gentle rocking.
Is it possible to install a more powerful lamp?
Using a lamp with a higher power than indicated in the instructions (usually more than 15-25 W) is strictly not recommended. This can lead to overheating of the plastic of the lampshade, its deformation and even melting of the socket, which creates the risk of a short circuit inside the refrigerator compartment.
Pay attention to the markings applied to the metal part of the base or to the glass of the old lamp. Voltage and wattage parameters may be indicated there. If the markings have worn off, it is better to take the old lamp with you to the store for a visual comparison.
It is also worth mentioning LED replacement lamps. They consume less energy and heat less, but their installation sometimes requires removal of the starter or choke when it comes to replacing fluorescent tubes. For conventional incandescent lamps, replacing with an LED analogue with an E14 base is possible, but you need to pay attention to the dimensions so that the bulb does not rest against the walls of the lampshade.
Removing the lampshade depending on the model
The process of removing the protective cap (canopy) directly depends on the design features of your model Ariston. Manufacturers use different fastening methods to ensure tightness and aesthetic appearance. Let's look at the three most common options that you may encounter.
In the first case, the lampshade is held in place by friction and a tight fit. It simply slides onto the lamp body. To remove it, you need to carefully grab the side edges with your fingers and pull it towards you. Sometimes you need to turn it slightly counterclockwise if there are guide grooves. Do not use excessive force to avoid breaking the plastic ears.
The second option involves the presence of a fixing screw. Often it is hidden under a decorative plug or located deep in the body of the lampshade. A thin flat head screwdriver may be required for access. After unscrewing the screw, the lampshade is removed with a slight movement of the hand. Be careful not to lose a small screw that could fall onto the refrigerator shelves.
The third type of fastening is latches. They can be located on the side or on top of the lampshade. To unlock them, you need to press the latch tongue with a screwdriver or a fingernail, while simultaneously pulling out the lampshade. A characteristic click will indicate that the latch is unlocked. In some models, the latches are hidden and require access by removing the top shelf.
| Fixation type | Tool | Action | Risks |
|---|---|---|---|
| Tight fit | No | Pull towards yourself | Plastic crack |
| Screw | Screwdriver | Unscrew and remove | Loss screw |
| Latch | Flat object | Press and pull out | Tab break |
| Thread (rarely) | No | Turn counterclockwise. | Thread breakage |
Removing the old lamp and installing a new one
After successfully removing the lampshade, you have access to the lamp itself. If it is a threaded base E14, grab the lamp by the metal part (base), and not by the glass bulb. Glass can be fragile, and if squeezed too hard, it will break in your hand, which is especially dangerous if there are fragments of tungsten filament inside.
Unscrew the lamp counterclockwise with smooth movements. If it becomes stuck or rusted (which happens in a humid environment), do not pull sharply. Try to loosen it slightly, rotating it in both directions, gradually increasing the amplitude. In rare cases, when the base has oxidized, you may need to use pliers, but proceed with extreme caution.
Screw in the new lamp all the way, but without fanaticism. Excessive force may cause the base to jam in the socket, making the next replacement a problem. It is enough to feel confident resistance at the end of the stroke. If you have a tubular lamp, insert it clearly along the guides, observing the orientation of the contacts.
Before installing the lampshade back, be sure to wipe it from the inside with a dry cloth. Over the years of operation, grease and dust accumulate on the walls, which reduce the brightness of the lighting. A clean lampshade will provide better light output even from an ordinary light bulb.
⚠️ Attention: It is strictly forbidden to touch the glass bulb of a halogen lamp with bare hands. Fat from the skin remaining on the glass, when heated, will cause local overheating and rapid burnout of the lamp. If touched, wipe with alcohol before installation.
Checking the system functionality
After installing the new lamp and putting the lampshade in place, do not rush to load the products. First you need to check if the system is working correctly. Plug in the refrigerator and wait until the light comes on. In most models, the light turns on when the limit switch contacts open, that is, when the door is open.
Open the refrigerator door. If the light comes on, congratulations, the replacement was successful. Pay attention to the absence of flickering or humming, which may indicate poor contact in the socket or poor quality of the lamp itself. If an LED is used, it should light up instantly, without delay.
If the light does not light up, there may be several reasons. First, check whether the lamp is seated tightly in the socket. Secondly, the limit switch (button or magnetic sensor), which responds to the opening of the door, could be stuck or damaged. Try pressing the limit switch button several times with your finger, simulating the closing and opening of the door.
It is also worth checking the integrity of the wiring if you have access to it and the appropriate skills. Sometimes wires fray at bends or near door hinges. However, if you are not confident in your abilities, it is better to limit yourself to a visual inspection and call a specialist.
Typical errors and troubleshooting
When doing self-repair, users often make mistakes, which may lead to additional problems. One of the most common is using a higher power lamp. This leads to melting of the plastic and a violation of the temperature regime, since an incandescent lamp is, in fact, a small heating element.
Another mistake is ignoring the state of the cartridge. If the contacts inside are blackened or oxidized, the new lamp may quickly burn out or simply not work. In such cases, it is necessary to clean the contacts or replace the entire cartridge, which is a more complex repair.
Do not forget about cleanliness. A dirty lampshade can create the illusion that the lamp is dim, when in fact it is simply covered with a layer of grease. Regular cleaning of the internal elements of the refrigerator extends their service life and improves illumination.
- 🔌 Ignoring safety: Attempting to replace without disconnecting from the network may result in electric shock or short circuit.
- 💡 Wrong type of lamp: Installing a lamp with an E27 base instead of an E14 (or vice versa) is physically impossible or will lead to damage to the socket.
- 🧊 Working in the cold: An attempt to remove the plastic shade immediately after defrosting, when the plastic is still cold and fragile, often ends in cracks.
If you encounter a situation where the lamp is blinking, this may be a sign of poor contact or problems with the control unit (if it adjusts the brightness). In modern models Ariston with electronic control, the malfunction may be displayed as an error code on the display.
Frequently asked questions (FAQ)
Is it possible to use an LED lamp instead of a regular one in an Ariston refrigerator?
Yes, you can if the base matches (usually E14). LEDs heat less and last longer. However, make sure that the LED lamp is no larger than the original one, otherwise it may not fit under the lampshade. Also, some LEDs may not work correctly with the electronics of the refrigerator, causing a faint glow even when the light is turned off.
What to do if the lamp base comes off the bulb and remains in the socket?
In this case, you need to turn off the power to the refrigerator. Then, using narrow-nose pliers or tweezers, carefully unscrew the remaining metal part of the base from the socket counterclockwise. Be careful not to damage the contacts inside the socket. If the base is stuck, you can drop a little WD-40, but then be sure to thoroughly wipe everything dry.
Why does the light bulb in the refrigerator burn out so often?
Frequent burnout can be caused by power surges in the network, vibration (if the refrigerator is uneven or often slams the door), or using a lamp of the wrong power. Also, the cause may be oxidation of the contacts in the socket, which causes the lamp to operate in extreme mode.
Where can I find the lamp layout diagram for my Ariston model?
The diagram can be found in the operating instructions that came with the kit. If the paper version is lost, use the technical data sheet on the manufacturer's official website by entering the exact model (P-number) indicated on the sticker inside the chamber.
Is it safe to leave the refrigerator open during replacement?
Opening the door briefly (5-10 minutes) will not cause significant harm to the food or the compressor. However, try not to keep the door open longer than necessary to avoid defrosting the evaporator and increasing the temperature inside the chambers.
