A sudden turning off of the light inside the refrigerator compartment is not just a minor inconvenience, but a signal that it is time to service the equipment. When you open the door of your loved one Ariston and see only darkness, this often means that the incandescent lamp has burned out or the LED module has failed. Fortunately, in the vast majority of cases, replacing this element does not require calling a technician and can be done independently in a few minutes.
Before taking active steps, you need to make sure that the problem lies in the light source, and not in the electrical network or door switch. Ariston refrigerators are known for their reliability, and their design provides easy access to the main service points nodes. In this article, we will analyze in detail the diagnostic and replacement process so that you can return full lighting to your unit.
It is worth noting that ignoring this malfunction may lead to you no longer noticing expired products or poorly closed packages. Proper lighting is not only about comfort, but also about food hygiene. Let's look at what tools you will need and how to safely carry out the procedure.
Diagnostics of the malfunction and preparation of tools
The first step should always be a thorough diagnosis. Do not rush to disassemble the lamp until you are sure that electricity is supplied to the device. Check to see if the light on the control panel is on, if there is one, and if the refrigerator itself is working and cooling food. If the unit is functioning normally, but there is no light, most likely the problem is in the lamp.
⚠️ Attention: Before starting any work inside the refrigerator, be sure to disconnect the device from the power supply. Unplug the plug from the socket to eliminate the risk of electric shock if you accidentally touch the contacts.
For replacement you will need a minimum set of tools. In most cases, a flathead screwdriver will be sufficient to gently pry the plastic casing open. However, in some models Ariston with the system No Frost or in modern series, a Phillips screwdriver or even pliers may be required if the base is jammed.
Also prepare a new light source in advance. In order not to make a mistake with your choice, it is better to first remove the burnt out lamp and look at the base markings. The most common types are E14 (minion) or specific tubular lamps for built-in shades. Buying the wrong model will lead to wasted time and trips to the store.
Here is a list of what you should have on hand before starting repairs:
- 🔦 A new light bulb of the appropriate type and power.
- 🪛 Flathead and Phillips screwdrivers (just in case).
- 🧤 Fabric gloves (to protect your hands and prevent greasy marks).
- 📱 Phone with the camera on (to take a picture of the connection diagram, if it is complex).
Types of lamps and shades in Ariston refrigerators
Design of lighting fixtures in refrigerators Ariston can vary significantly depending on the year of manufacture of the model and its price segment. In older models, classic incandescent lamps with an E14 base are most often used, which are screwed into a socket hidden under a plastic diffuser. They are cheap and available, but have a short service life.
Modern units are increasingly equipped with LED backlight. In such systems, the light source can be either a separate LED lamp or a solid LED strip mounted around the perimeter of the rear wall. If this is your option, simply replacing the light bulb may not help, and you will need a more complex repair or replacement of the entire lighting module.
Plafonds also come in different types. In some models, this is a transparent or matte cap that is held on by latches. In others, it is a complex plastic structure that covers not only the lamp, but also the thermostat or air channels of the system No Frost. Such elements must be removed with special care so as not to damage the fragile plastic, which becomes very brittle in the cold.
Below is a table that helps identify the type of lamp by appearance and refrigerator model:
| Light source type | Appearance | Type of base/mount | Where found |
|---|---|---|---|
| Incandescent lamp | Pear-shaped, glass | E14 (thread) | Old and budget models |
| Halogen lamp | Small, with two pins | G4 / G9 | Middle class models |
| LED lamp | Plastic body, no heat | E14 or built-in | Modern series |
| LED strip | Strip with diodes | Soldering or connector | Premium models, Side-by-Side |
It is important to understand that the power of the new lamp should not exceed the power of the old one. Typically, refrigerators use lamps ranging from 15 to 40 watts. Using a lamp that is too powerful can lead to melting of the plastic lampshade and damage to the wiring.
Step-by-step instructions: removing the lampshade and replacement
The replacement process begins with dismantling the protective lampshade. In refrigerators Ariston it is most often attached to plastic latches. Find the junction of the lampshade with the wall of the chamber - usually there is a small protrusion or recess intended for gripping with a tool.
☑️ Algorithm for replacing the lamp
Carefully insert a flat screwdriver into the gap between the lampshade and the wall of the refrigerator. Do not use excessive force, but be gentle, being careful not to scratch the inside of the camera. The plastic should snap off with a characteristic but quiet click. If the lampshade is secured with a screw, it must first be unscrewed.
After removing the protection, you will have access to the lamp base. If it is a threaded connection, unscrew the burnt element counterclockwise. If the lamp has a pin connection, it must be gently pulled towards you, slightly rocking from side to side. Be careful: if the lamp breaks inside the socket, the remaining base will have to be removed with pliers.
⚠️ Attention: Never touch the glass bulb of a new halogen lamp with your bare hands. Fat from the skin will remain on the glass and, when heated, will lead to local overheating and rapid burnout of the lamp. Use a napkin or gloves.
Insert the new lamp into the socket until it stops. Make sure it fits snugly and doesn't wobble. Then return the plastic shade to its place, snapping it until it makes a characteristic sound. Now you can plug in the refrigerator and check the result.
Features of replacement in models with No Frost
Refrigerators Ariston with the system No Frost have a more complex internal architecture. In such models, the lighting fixture is often located not just on the ceiling, but is built into the back wall or hidden behind decorative panels, which are also part of the air circulation system.
The main feature here is the need to dismantle additional elements. Sometimes accessing a lamp requires removing a shelf, crisper drawer, or even part of the back panel. This requires more time and accuracy. It is important not to break the tightness of the air ducts and not to damage the evaporator, which in such models is located close to the walls of the chamber.
If you see that access to the lamp is blocked by a plastic panel with many latches around the perimeter, do not try to tear it off by force. Examine the fastenings carefully. Often such panels are held on by hidden screws covered with decorative plugs. They must be removed first.
What to do if the lamp in No Frost is not available?
If replacing the lamp requires complete disassembly of the back wall and dismantling of the evaporator, and you do not have experience in such work, it is better to contact a service center. Inept actions can lead to depressurization of the cooling system and costly repairs.
Also in models with No Frost problems with sensors are more common, which can turn off the light if the door is not closed tightly, or if the diagnostic system detects an error. Therefore, if replacing the lamp does not help, it is worth checking the tightness of the door and the operation of the magnetic seal.
Problems with the base and wiring
Sometimes it happens that a new working lamp does not light up. This may indicate a problem with the socket or wiring. In older refrigerators, the contacts inside the cartridge could oxidize or burn out. Visually inspect the socket: if you see black carbon deposits or melted plastic, you will need to replace the socket itself, not just the lamp.
If the contacts look normal, try carefully bending the central contact inside the socket (after unplugging the refrigerator!). Sometimes it falls down and does not reach the lamp base. Do this very carefully using a dielectric tool.
Another common problem is a faulty door switch. It is he who completes the circuit when you open the door. If the switch button is stuck or damaged, the light will not turn on, even if the lamp is intact. Check whether the button moves easily, whether there is ice or dirt on it.
- 🔍 Oxidation of contacts: Clean the contacts with fine sandpaper or a file.
- 🔌 Wire break: Check the integrity of the wires going to the lamp, especially in the bend areas.
- 🔘 Button sticking: Work out the switch button several times manually.
If you find melting of the plastic around the cartridge, this is an alarming sign. This means that a lamp of higher wattage than permitted was previously installed, or the contact was poor, causing heat. It is dangerous to operate such a cartridge - it needs to be replaced.
Common mistakes during self-repair
DIY Repair is a great way to save money, but beginners often make common mistakes that can lead to new breakdowns. One of the most common is the use of a metal tool without insulation near live contacts (if you forgot to unplug it from the socket) or simply careless handling leading to a short circuit.
Another mistake is ignoring the temperature regime. The plastic of a refrigerator is more elastic at room temperature, but if you have just defrosted the unit or, conversely, it has been running at full capacity, the plastic may be brittle. Let the refrigerator warm up to room temperature before removing the plastic elements.
⚠️ Attention: Do not use glue to fix the shade or lamp! Plastic and glue can react chemically, and when heated, the glue can release toxic substances that end up on food. Everything should be held on by standard latches.
It is also a mistake to install a lamp of the wrong shape. Even if the base fits, a lamp that is too long or wide may rest against the walls of the lampshade or shelf, creating pressure on the glass. When the compressor vibrates, such a lamp will quickly break or damage the lampshade.
FAQ: Frequently Asked Questions
Why is the light blinking in the Ariston refrigerator?
Blinking can be caused by several reasons: bad lamp contact in the socket, faulty door switch (contact bounce) or problems with the control unit in modern models. This can also happen during power surges in the network.
Is it possible to install an LED lamp instead of a regular one?
Yes, you can if the base matches (usually E14). LED lamps are even preferable, as they heat up less. The main thing is to make sure that the lamp is designed to work in conditions of vibration and low temperatures, although most household LEDs can withstand this.
Where can you find the marking of the refrigerator model?
The marking plate in refrigerators Ariston usually located inside the refrigerator compartment on the side wall, on the base below or on the back wall outside. There is a complete model index that will help you find the exact circuit.
What to do if the lamp inside the socket breaks?
De-energize the refrigerator. Carefully unscrew the remaining base with pliers, being careful not to damage the threads of the socket. If there are shards of glass left inside, remove them with tweezers. Be extremely careful so that the fragments do not fall into the products or onto the shelves.
The LED backlight has stopped lighting completely, what's wrong?
If you have an LED strip and it goes out, most likely the driver (power supply) has burned out or there has been a break in the strip itself. In this case, simply replacing the element will not be enough; diagnostics of the electrical circuit and, possibly, replacement of the entire backlight module will be required.
