A sudden breakdown of lighting in the refrigerator compartment is not just a household trifle, but a real problem that interferes with the full operation of the equipment. When you open the door Biryusa 133 and see only darkness, there is a natural desire to immediately fix the problem, because searching for products in the twilight is inconvenient and ineffective. Most often, the reason lies in a burnt-out incandescent lamp, the resource of which has come to an end, or, more rarely, in a broken contact in the socket.
Fortunately, the model Biryusa 133 is structurally quite simple and allows you to replace the light source yourself, without resorting to the services of expensive service centers. To perform this operation, you do not need complex professional equipment or deep knowledge in the field of electrical engineering. A basic set of tools, basic safety measures and care when working with fragile elements are enough.
In this article we will analyze in detail the entire process: from preparing the workplace to checking the functionality of the new lamp. You will learn what types of bases are used in different modifications of this model, how to carefully dismantle the protective shade without damaging the plastic, and why you should think about switching to LED lighting now.
Preparation for repairs and safety measures
Before you begin any manipulations with electrical appliances, you need to completely protect yourself and your equipment. The first and most important step is complete shutdown of the refrigerator from the electrical network. Do not rely only on the switch on the case or the temperature controller - unplug the power cord from the outlet. This will eliminate the risk of electric shock, since voltage may remain in the lamp socket even when the light is turned off.
After turning off the power, let the equipment stand for 10-15 minutes. This is necessary not only to stabilize temperature conditions, but also to ensure that the plastic, which could become brittle from the cold, warms up a little and becomes elastic. Sudden movements at low temperatures can lead to cracks in the lamp housing.
⚠️ Attention: Never try to unscrew the lamp or remove the lamp while the refrigerator is connected to the network. Even briefly shorting the contacts with your fingers or a metal tool can lead to serious injury or wiring failure.
Prepare the work area in advance. You will need a stable stepladder or stool, since the lamp in the model Biryusa 133 is located at the top of the chamber, and reaching for it while standing on the floor is inconvenient and dangerous. Also prepare a dry cloth for wiping the contacts and a new lamp, selected in advance. If you have a flashlight, turn it on - the light from it will help you better see the internal structure of the lamp in the darkness of the chamber.
☑️ Preparing to replace the lamp
Determining the type of lamp and base
The model Biryusa 133 was produced in various modifications in different years, so there is no universal answer to the question “which lamp is inside.” In most cases, these refrigerators use standard incandescent lamps with a base E14 (minion), the power of which is usually 15 W. However, in newer versions or after previous repairs, the owner could install LED analogues.
In order not to make a mistake with the purchase, it is best to unscrew the burnt-out element and take it with you to the store as a sample. Pay attention to the markings on the glass or metal part of the base. If the lamp breaks inside the socket (which happens rarely, but it does happen), you will have to rely on the characteristics of the lampshade and the socket.
Modern industry offers an excellent alternative to the classic "Ilyich light bulbs" - LED lamps for refrigerators. They have a number of undeniable advantages:
- 💡 Energy efficiency: consume 8-10 times less electricity, which for a device operating 24/7 provides significant savings.
- 🌡️ Thermal resistance: special refrigeration LED lamps designed to operate at low temperatures, unlike conventional household LEDs, which can flicker or go out in the cold.
- ⏳ Durability: LED service life is thousands of hours, so you will forget about the problem of replacement for many years.
Is it possible to install a regular LED lamp?
In theory, it is possible if the base matches (E14). However, regular LED lamps may not work correctly at low refrigerator temperatures—the light may become dimmer or pulsate. It is better to choose specialized models marked “for refrigerators” or “fridge”.
When choosing a new lamp, also consider its dimensions. Some high-power LED models can be longer than standard 15-watt incandescent bulbs. If the bulb is too large, it may rest against the walls of the lampshade or interfere with the closing of the door, which will lead to overheating and rapid breakdown.
Removing the protective lampshade
Access to the lamp in the refrigerator Biryusa 133 is covered with a plastic diffuser (shade). The design of the lampshade mounting may vary depending on the year of manufacture of the unit. In some versions it is held on by latches, in others it is fixed with a screw or self-tapping screw in the center or at the end.
Carefully inspect the plastic cap. If you see a hole with a screw, use a suitable screwdriver (usually a Phillips PH1 or PH2) to remove it. Be careful not to strip the threads in the soft plastic. If there are no visible fasteners, it means that the lampshade is held on spring latches.
To remove the lampshade on the latches, you need to find their locations. Usually these are the side edges or the top of the diffuser. Take a flathead screwdriver or a knife with a wide blade (after wrapping a cloth around the blade so as not to scratch the plastic) and carefully pry up the edge of the lampshade. Do not use excessive force - plastic becomes brittle in the cold.
| Type of fastening | Tool | Dismantling features |
|---|---|---|
| Screw | Phillips screwdriver | Unscrew the central or side screw, then the lampshade can be freely removed downwards. |
| Latches (on the side) | Flat screwdriver | Pry up the side edge, press the lock and pull the lampshade towards you. |
| Latches (top) | Without tools | Push the bottom of the lampshade up until it clicks, then release it. |
After successfully removing the diffuser, you will have access to the socket and the lamp itself. At this stage, it is recommended to wipe the inner surface of the lampshade with a soft, damp cloth, since during operation dust and dirt may have accumulated there, which reduce the brightness of the lighting.
The process of replacing the light source
Now that access is open, you can begin the actual replacement. If you have a classic incandescent lamp installed, grab the glass bulb (if intact) or the base and unscrew it counterclockwise. There is no need to apply much effort, the thread should go easily. If the lamp breaks in the socket, you will need to use pliers with thin jaws to carefully unscrew the remaining base, after making sure that the device is de-energized.
Screwing in the new lamp is done in the reverse order: insert it into the socket and rotate clockwise to stop Do not overtighten the lamp, especially if it is a fragile glass bulb - this may lead to its destruction at the moment of switching on or create difficulties during the next replacement. A light fixing force is sufficient.
In case of installation LED lamps with a driver (if it is not a direct analogue of 220V, but requires a converter), the circuit may be more complex. However, in 99% of cases for Biryusa 133, ready-made solutions with an E14 socket for 220V are used, which do not require wiring alterations. Just screw in the LED analogue in the same way as a regular lamp.
⚠️ Attention: It is strictly forbidden to touch the metal contacts of the socket with your fingers or conductive objects until final assembly and switching on. Even a residual charge in the capacitors (if they are in the circuit) or accidental switching on by someone in the household can be dangerous.
After installing a new lamp, do not rush to assemble the structure completely. You can temporarily (with caution) plug in the refrigerator to see if the light comes on. If the lamp lights up, you did everything correctly. Immediately turn off the power again to complete assembly.
Assembly and performance testing
The final stage is installing the lampshade in place. Make sure that the wires inside are not pinched or touching heating elements (if there are any nearby) or sharp edges. The lampshade should fit into its regular place tightly, without gaps. If the fastening is screw, tighten the self-tapping screw, but do not overdo it so as not to crack the plastic.
If the lampshade is snapped, align the guides and press until you hear a characteristic click. Check if the structure is wobbly. The tightness of this unit is important not so much for light as for maintaining cold - through a loosely closed lampshade, cold air can actively escape, causing the compressor to work more intensely.
After assembly, plug in the refrigerator. Open the door - the light should come on instantly (for LED) or with a slight delay (for incandescent lamps). Close the door and the light should go out. This checks not only the lamp, but also the serviceability of limit switch (button or lever), which reacts to the position of the door.
In the first hours after replacement, observe the operation of the equipment. The lamp should not make a crackling noise, buzz, or heat up the lampshade excessively. If you installed an LED, it practically does not heat up, which is an additional advantage for the safety of the plastic elements of the refrigerator.
Possible malfunctions and their elimination
Sometimes it happens that you replaced the lamp, but the light still did not appear. In this case, you should not panic or immediately commit to a new lamp - a defect is possible, but less common than other reasons. First of all, check whether the lamp is screwed tightly into the socket. Often, due to oxidation of contacts or weak clamping, there is no circuit.
If everything is in order with the contact, the problem may lie in limit switch. This mechanism is located inside the chamber (usually in the side wall or above the doorway) and mechanically opens the circuit when the door is closed. Over time, its contacts may oxidize or stick. Try quickly pressing the switch button/lever with your finger several times - sometimes this helps knock off the oxide film.
A more serious, but rare problem for this model is a broken wiring or malfunction of the thermostat (in some circuits the light circuit is tied to it). If you do not have the skills to work with a multimeter and electrical circuits, further independent repairs can be dangerous.
- 🔍 Checking the cartridge: inspect the “antennae” inside the cartridge - if they are too low, carefully (without power!) lift them with a screwdriver for better contact with the base.
- 🔌 Integrity of the wires: visually inspect the wires going to the lampshade for melting or cutting.
- 🔋 Test lamp: if possible, check the new lamp in another working device to exclude manufacturing defects.
⚠️ Attention: If you smell burning, see sparking or hear a crackling sound inside the lampshade immediately after turning it on, immediately unplug the refrigerator! You cannot operate such a device - there is a high risk of short circuit and fire.
In most cases for the model Biryusa 133 replacing the lamp solves the problem completely. This refrigerator is distinguished by a reliable and simple electrical circuit, where complex breakdowns of the lighting module rarely occur.
What to do if the new lamp burns out immediately?
If the new lamp burns out a few seconds or minutes after turning on, the problem is not in it. Most likely, there are power surges in the refrigerator network, the cartridge is faulty (short circuit occurs) or the limit switch is malfunctioning. Diagnostics by an electrician is required.
Frequently asked questions (FAQ)
What is the maximum lamp power that can be used in Biryusa 133?
It is recommended to use lamps with a power of no more than 15 W for incandescent lamps. Using more powerful lamps (for example, 25-40 W) can lead to melting of the plastic lampshade and deformation of the socket due to excess heat. If you need brighter light, switch to LED analogs.
Can the lamp be washed in hot water?
The plastic from which the diffuser is made can be deformed at high temperatures. Wash it in warm water and a mild detergent. Do not use abrasive sponges to avoid leaving scratches that will scatter light and spoil the appearance.
Why does the LED lamp in the refrigerator flicker?
Flashing LED lamps in the refrigerator are often caused by the fact that it is not designed to work with certain types of switches or has a low quality driver. Also, the cause may be interference from the wiring or a malfunction of the limit switch, which “sparks”. Try replacing the lamp with a different model or manufacturer.
Where to buy an original lamp for Biryusa?
There are no special “original” lamps with the Biryusa logo. These are standard products. You can buy them at any hardware store, electrical store or supermarket. The main thing is the base (usually E14) and the appropriate size.
Do you need to defrost the refrigerator before replacing?
Full defrosting is not necessary if you work quickly. However, if there is a lot of frost in the chamber or products that interfere with access, it is better to unload the contents. Remember that without light you can see worse, so provide good external lighting.
