Suddenly going out of light in the refrigerator compartment is not just a minor inconvenience, but a signal that lighting device it is out of order. Equipment owners Hauswirt often face the need to quickly replace a burnt-out lamp in order to continue comfortable use of the unit. The lack of lighting makes it difficult to find products, especially on the lower shelves or in the depths of the chamber, where natural light from the open door is no longer enough.
The process of replacing the light source in refrigerators Hauswirt usually does not require calling a technician and special tools. It is enough to understand the basic principles electrical safety and know how to properly dismantle the protective shade. In this article we will analyze in detail all stages of the work, from choosing a suitable light bulb to the final check of the system's functionality.
It is worth noting that modern models may differ in the design of the lampshades, but the general algorithm of actions remains similar for most series. Hauswirt refrigerators most often use 15 W E14 incandescent lamps or their LED equivalents. Before starting any manipulations, make sure that you have prepared a working place and necessary tools.
Preparation for replacement and selection of consumables
Before you begin dismantling the old element, you must purchase the correct replacement. Using unsuitable parts may result in overheating plafond or wiring failure. In refrigeration technology, special lamps are used that are resistant to vibration and low temperatures, so ordinary household analogues are not suitable here.
For the model Hauswirt it is critically important to choose a product with a base E14, since the cartridge is designed for this particular size. If you decide to install an LED lamp (LED), make sure that it is designed for use in refrigerators and has a wide operating temperature range. Incandescent lamps, in turn, should have a power of no more than 15–25 W, so as not to melt the plastic diffuser.
You will also need a minimum set of tools. In most cases, a flathead screwdriver with a thin blade and perhaps some pliers will suffice if the shade is secured tightly. Don't forget to prepare a dry rag to wipe the contacts and the lamp itself from dust and condensation.
- 💡 Lamp with E14 base (15 W) or a specialized LED analog.
- 🔧 Flat screwdriver with a thin blade for prying up the latches.
- 🧤 Dry cotton cloth or napkin for cleaning.
- 🔦 Flashlight (to illuminate the work area when the lights are off).
⚠️ Attention: Never use lamps with a power higher than that specified in the instructions (usually 15 W). Excessive power will lead to deformation of the plastic diffuser and may cause a short circuit in the refrigerator wiring.
Safety measures and power outage
Working with electrical appliances always requires compliance with strict safety rules. The refrigerator Hauswirt is connected to a 220 V network, and although the voltage in the lamp circuit is low, the risk of electric shock if handled carelessly with metal tools inside the chamber remains. In addition, some models may have features groundingthe violation of which is dangerous.
The first step should always be to completely de-energize the device. Simply closing the door and unplugging the plug from the socket is not enough if access to the socket is difficult - in this case, it is recommended to turn off the machine on the panel. This is guaranteed to eliminate the risk of accidentally turning on the compressor or applying voltage to the contacts during operation.
After turning off, let the equipment stand for 5-10 minutes. This time is necessary for the capacitors in the electronic control module to discharge, if present in your model. This will also allow the temperature inside the chamber to stabilize, which is especially important if you are planning a replacement in the winter.
- 🔌 Unplug the power cord from the outlet or turn off the machine.
- ⏳ Wait 10 minutes for the electronic components to discharge.
- 🧤 Wear rubber gloves if your hands are prone to sweating.
- 🚫 Do not touch the metal parts of the case with wet hands.
⚠️ Attention: If you find traces of melting of the plastic around the cartridge or blackening of the contacts, do not turn on the refrigerator. This is a sign of a serious wiring fault that requires professional repair.
Removing the protective shade and accessing the lamp
The design of the lampshade in refrigerators Hauswirt may vary depending on the year of manufacture and the specific series. In most cases, the protective cap is snapped on or secured with a single screw. You can determine the type of fastening by visual inspection: if the screw is visible, you need to unscrew it, if not, carefully pry off the edge of the lampshade.
To remove the lampshade with snaps, take a flat-head screwdriver and wrap its tip with a cloth so as not to scratch the plastic. Insert the tool into the gap between the refrigerator body and the lampshade, usually at the bottom or side. Using a slight twisting motion, release the latch. Do not use excessive force, as the plastic becomes brittle in the cold and may crack.
If the lamp is held on by a screw, unscrew it counterclockwise. Sometimes the screw may be hidden under a decorative plug, which also needs to be carefully removed. After releasing the fasteners, the lampshade can be easily removed downwards or to the side, providing access to the lamp base.
- 🔍 Inspect the lampshade for visible screws or plugs.
- 🛠️ Pry up the edge of the lampshade with a screwdriver if the screws are not visible.
- 🌀 Unscrew the fastening screw, if present.
- 👐 Carefully remove the diffuser, holding it with your hand.
☑️ Check before removing the shade
The process of replacing the source light
After removing the lampshade, you will see the lamp base screwed into the socket. If there was an incandescent light bulb, it may be hot if the refrigerator has been running recently, so be careful. Unscrew it counterclockwise, holding it by the glass bulb (if it is intact) or by the metal base.
If the lamp breaks inside the socket, the situation becomes more complicated. In this case, you need to use pliers to carefully unscrew the remaining base. You need to act slowly, trying not to damage the contacts inside the socket, since their restoration will require disassembling the entire refrigerator.
Screw in the new lamp until it stops, but without excessive force. Over-tightening may cause the chuck contacts to become deformed, causing sparking. Make sure that the lamp bulb does not touch the walls of the lampshade or other structural elements after installation.
What to do if the new lamp does not light up?
If the lamp does not light after replacement, check the tightness of the base in the socket. Sometimes the cartridge contacts become slightly bent. Carefully (with the power off!) bend them closer to the center. If this does not help, the problem may be a faulty door switch or wiring.
Comparison of types of refrigerator lamps
When choosing a new light source, many users are faced with a choice: keep the traditional incandescent lamp or switch to LEDs. Each option has its own advantages and disadvantages, which affect the durability and energy consumption of the device Hauswirt.
Incandescent lamps are cheaper and more common, but they generate more heat and consume more energy. LED analogues (LED) practically do not heat up, which is safer for plastic parts, and last many times longer. However, the cost of LED lamps is higher, and it is important to choose models with the correct emission spectrum.
| Characteristics | Incandescent lamp | LED | Halogen |
|---|---|---|---|
| Service life | 1000 hours | 30,000+ hours | 2000–4000 hours |
| Heating | Strong | Minimum | High |
| Energy consumption | 15–25 W | 1–3 W | 20–35 W |
| Price | Low | Average/High | Average |
| Sensitivity to cold | Low | Requires special. execution | Average |
For refrigerators Hauswirt specialized LED lamps are the best choice, since they do not create excess heat inside the chamber, helping the compressor operate in a more economical mode. This is especially true for models with a system No Frostwhere stable temperature conditions are important.
Assembly and performance testing
After installing a new lamp, it is necessary to return the protective shade to its place. Make sure that the sealing rubber (if there is one) lies flat and is not pinched. The lampshade should snap into place with a characteristic click or fit snugly to the body without gaps.
Now you can connect the refrigerator to the network. Open the camera door and the light should come on immediately. If your model has a switch, check its operation: when pressed (simulating a closed door), the light should go out. This is an important point for maintaining cold.
Close the door and listen to the operation of the unit. There should be no extraneous clicks or buzzing. If everything went well, you can download the products. During the first hour of operation, it is recommended to periodically check whether the lampshade area is heating up.
- 🔒 Put the lampshade in place until it clicks.
- 🔌 Plug in the refrigerator.
- 💡 Check that the light comes on when you open the door.
- 🚪 Make sure that the light goes out when closing.
Possible malfunctions and their elimination
Sometimes it happens that even after replacement the lamp does not light up. This may indicate a faulty door switch or wiring problem. The switch often fails due to constant mechanical stress and temperature changes.
You can check the switch by closing its contacts (with the power off!) or by ringing with a multimeter. If it is faulty, replacing it also does not require complex skills and takes a few minutes. In more rare cases, the problem lies in the oxidation of the socket contacts.
If you notice that a new lamp burns out quickly, there may be voltage surges in the network of your home. In this case, it is recommended to use a stabilizer or install a diode lamp, which is less sensitive to voltage changes.
⚠️ Attention: Technical characteristics and arrangement of elements may vary slightly depending on the specific model of the Hauswirt refrigerator. Always check the official user manual that came with your device, especially if you see non-standard mounts.
Can you use a higher wattage lamp?
Using a lamp with a power higher than 15 W (for example, 40 or 60 W) is strongly discouraged. The plastic of the ceiling in refrigerators is designed for a certain temperature. A lamp with a higher power will melt the plastic, which will lead to its deformation, the appearance of an unpleasant odor and a possible fire.
How can you tell that the lamp has burned out if it is dark in the refrigerator?
If the light does not light up when you open the door, try gently shaking the lamp (with the refrigerator on, being careful). If a spark or short-term glow appears, the filament is broken. You can also unscrew the lamp and check it visually: blackening of the bulb or breaking of the filament indicates a malfunction.
Is it possible to replace a regular lamp with an LED one in an old refrigerator?
Yes, you can. The main thing is that the base matches (usually E14), and the dimensions of the new LED lamp allow it to fit under the lampshade. LEDs consume less energy and heat up less, which is a plus for any refrigerator, regardless of the year of manufacture.
Why does the light blink in a Hauswirt refrigerator?
Flashing can be caused by poor contact in the socket, a faulty door switch or unstable voltage in the network. If the lamp is LED, blinking sometimes indicates that the lamp driver is incompatible with the network parameters or that it is not designed to work with dimmers (although dimmers are rare in refrigerators).
Where can I find the article number of the original lamp for my model?
The article number is usually indicated in the operating instructions in the "Replacing the lamp" section or on a sticker inside refrigeration chamber. If the information is lost, it is enough to know the type of base (E14) and power (15 W) to select a compatible analogue in any electrical goods store.
Is it dangerous to change the lamp yourself?
If you follow the electrical safety rules (mandatory disconnection from the network!), the procedure for replacing the lamp is not dangerous. The risk is minimal if you do not use metal tools for live picking and do not apply excessive force to plastic parts.
