The sudden disappearance of light in the refrigerator compartment is always a signal that the normal operation of the device is disrupted. Owners of equipment Atlant with a bottom freezer often encounter incandescent lamp burnout, which creates significant discomfort when searching for food in the dark. Fortunately, this element is not a complex unit, and its replacement does not require calling a technician or special skills.
The process of restoring lighting takes only a few minutes if you know the correct sequence of actions and the type of base for your model. In this article, we will analyze in detail how to independently replace the light bulb, what tools you will need and how to avoid common mistakes that can lead to damage to the lampshade or wiring.
Before you start work, it is important to understand that even a simple procedure requires compliance with the rules. electrical safety. We will consider the nuances of dismantling the protective lamp, choosing a suitable LED lamps replace the old one and check whether the problem lies in the wiring itself or the switch.
Preparation for work and measures safety
The first and most important step before any intervention in the electrical part of a household appliance is to completely disconnect from the network. Atlant refrigerator must be de-energized to eliminate the risk of electric shock or short circuit when unscrewing the base.
⚠️ Warning: Never try to replace a lamp while the power cord is plugged in, even if you are simply replacing a burnt-out element. Wet hands or accidental contact with the metal parts of the cartridge can be dangerous.
After turning off the equipment, it is necessary to prepare the workplace. You will need a stable stepladder or stool, as access to the ceiling in models with a bottom freezer is often located at the top of the refrigerator compartment. Prepare in advance a dry rag for wiping the internal surfaces and a new light bulb.
A minimal set of tools may be needed for the job. Most often, a flat-blade screwdriver is sufficient to gently pry up the lamp latches if they cannot be removed by hand. A multimeter will also come in handy if you want to check the voltage in the socket or the integrity of the contacts.
☑️ Preparing to replace the lamp
Determining the type of light bulb and choosing a replacement
In refrigerators Atlant different types of light sources can be used. Traditionally, these models installed classic incandescent lamps with a base E14 (minion) and a power of up to 15-25 W. However, in more modern versions, the manufacturer began to use LED modules.
If in your case a regular incandescent lamp has burned out, when buying a new one you should pay attention to the dimensions. A standard pear-shaped shape may not fit under a narrow lampshade, so it is better to choose models marked R39 or R50that have a more elongated or flattened bulb shape.
LED lamps (LED) will be an excellent alternative to the classics. They practically do not heat up, which is critical for the refrigeration chamber, where every degree of heat affects the operating mode of the compressor. In addition, LED elements consume less energy and last many times longer.
| Lamp type | Socket | Power | Advantages |
|---|---|---|---|
| Incandescent | E14 | 15-25 W | Low price, availability |
| LED (LED) | E14 | 1-3 W | Efficiency, no heating |
| Halogen | G4/G9 | 10-20 W | Bright light (rare in Atlant) |
| LED module | Specific | 1-2 W | Durability, compactness |
Dismantling the lampshade and removing the old lamp
Access to the light source in refrigerators Atlant with a bottom freezer is usually closed with a plastic lampshade. The design of the diffuser may differ depending on the series of the refrigerator. In some models, the lampshade is held on by screws, in others - on plastic latches, and in others - it is simply inserted into the grooves.
If you see screws, carefully unscrew them with a suitable screwdriver. If there are no fasteners, try pressing on the front or side of the lampshade (usually from the side of the doorway) and pulling down slightly. You need to act carefully, as plastic becomes brittle in the cold and can crack with a sharp jerk.
After removing the diffuser, access to the cartridge will open. The incandescent lamp is unscrewed counterclockwise. If the flask is broken and the base remains inside, it must be removed using pliers, after first turning off the power to the device. Be careful not to damage the contacts inside the socket.
⚠️ Attention: If the lamp is secured with hidden latches, do not use force. Try to carefully pry the edge of the plastic cover with a flat screwdriver, having first wrapped its blade with a cloth so as not to leave scratches.
Installing a new light source
Installing a new lamp is done in the reverse order. Screw the base E14 into the socket clockwise until it stops. Do not use excessive force: the lamp should fit tightly, but without distortion. If you are using an LED analogue, make sure that it sits level and does not touch the walls of the lampshade.
Before installing the lampshade in place, it is recommended to wipe its inner surface with a dry cloth. During operation, condensation or dust may have accumulated there, which, when heated (if it is an incandescent lamp), can create an unpleasant odor or even cause a short circuit.
Secure the lamp by snapping it until it clicks or tightening the fastening screws. Make sure the diffuser fits snugly and does not wobble. After this, you can turn on the refrigerator and check the functionality of the lighting system by opening the door.
What to do if the new lamp does not light
There are situations when replacing the light bulb does not bring results, and the light does not appear in the camera. In this case, the problem lies not in the light source, but in the power circuit. The first step is to check the serviceability of the new lamp by screwing it into another device, for example, a chandelier or table lamp with a suitable base.
If the lamp is working, the next candidate for testing is the door switch (limit switch). This mechanism is responsible for opening the circuit when the door is closed. Over time, the contacts inside it may oxidize or stick. Try sharply pressing the switch button with your finger several times - sometimes this helps restore contact.
The most serious reason may be a break in the wiring inside the case or oxidation of the contacts in the socket. If you notice blackening of the plastic around the cartridge or hear a cracking sound, further operation without repair is dangerous. In such cases, professional diagnostics of the electrical circuit is required.
How to check the limit switch with a multimeter?
To check, remove the switch and ring its contacts in the pressed and released state. In one of the positions the multimeter should show zero resistance (short circuit), and in the other - infinity. If the device is silent in both cases, the switch is faulty.
Switching to LED lighting: is it worth it?
Many refrigerator owners Atlant are thinking about upgrading the lighting system, replacing standard incandescent lamps with LEDs. This solution has many advantages: no heating, which is especially important for products lying on the top shelf, and significant energy savings.
However, there are nuances. Cheap LED lamps can create radio interference, which theoretically can affect the operation of the refrigerator control electronics, although modern models usually have built-in interference protection. Also, LEDs can produce a less warm, more “cold” light, which changes the visual perception of the color of products. Atlant Anti-interference protection is usually built-in. LEDs can also produce a less warm, “cooler” light, which changes the visual perception of the color of products.
If you decide to switch to LED, choose high-quality brands with good heat dissipation. Remember that even LEDs generate heat in the base area, and in the confined space of the lampshade this can shorten the life of the diode itself if it is not designed for such conditions.
Frequently asked questions and answers (FAQ)
Can a regular LED lamp for home be used in the Atlant refrigerator?
It can be used, but with caution. Conventional household LED lamps are not always designed to operate at low temperatures and in conditions of high humidity. It is better to buy specialized lamps for refrigerators or trusted brands that operate over a wide temperature range.
Why does the light bulb burn out immediately after replacement?
This may indicate a voltage surge in the network, a faulty socket (short circuit inside) or problems with the door switch. A poor quality new lamp may also be the cause. Check the cartridge contacts for the presence of carbon deposits.
What base is used in old Atlant refrigerators?
The vast majority of old and middle-aged Atlant refrigerator models use a base E14 (minion). The E27 base (standard large) is not used in these refrigerators due to their size.
Does it need to defrost the refrigerator before replacing the lamp?
Complete defrosting is not required. It is enough to disconnect the device from the network for 10-15 minutes to stabilize the temperature and protect yourself. However, if there is a lot of ice in the chamber that prevents access, local defrosting can be useful.
