Finding the exact identification number of a household appliance often becomes a task of increased complexity, especially when the technical passport has long been lost, and the stickers on the body have faded or become damaged. For refrigerator owners Biryusa this issue becomes especially acute when it is necessary to order spare parts, such as thermostats, seals or compressors, since even a slight discrepancy in the index can lead to the purchase of incompatible parts. A correctly identified refrigerator model is the key to successful repair and long service life of the equipment.
The manufacturer Krasnoyarsk plant refrigerators over the years has produced hundreds of modifications, each of which has its own design features. The number, stamped on the case or pasted on the nameplate, contains encoded information about the dimensions, number of chambers, type of refrigerant and even the year of manufacture. The exact match of the model index with the catalog number of the spare part is the only guarantee that the repair will be successful. In this article we will analyze in detail all possible locations of the markings and learn how to decipher complex alphanumeric codes.
Where to look for factory markings
The first place you should pay attention when searching for identification data is the interior space of the refrigerator compartment. On old models of the Soviet and early post-Soviet period, a metal plate (nameplate) was most often located on the inner wall of the refrigerator compartment, usually in the upper part or on the side, closer to the shelves. However, over time, these stickers could come off, wear off, or be painted over when trying to freshen up the interior of the camera. On more modern models, manufacturers often change the placement of the labels to improve aesthetics and protect against moisture. Now information can often be found:
On more modern models Biryusa Manufacturers often change the placement of labels to improve aesthetics and protect against moisture. Now information can often be found:
- 🏷️ On the inner side wall of the refrigerator compartment, closer to the doorway.
- 🏷️ On the inside of the door of the refrigerator or freezer (often at the end or in a niche).
- 🏷️ On the back wall of the case, outside (you need to move the refrigerator away from the wall).
- 🏷️ In the technical passport or warranty card, if they are preserved.
If nothing is found on the internal surfaces, carefully inspect the back wall of the unit. There may be an aluminum or plastic plate with embossed data. It is also worth looking into the compressor niche, although the information there is often of a technical nature and relates to the engine, and not to the cabinet itself. In rare cases, especially for built-in models, the nameplate may be glued to the end of the door or to the base part.
⚠️ Attention: Do not use sharp objects or aggressive chemicals to clean a dirty sticker. Mechanical impact can erase numbers, and solvents can completely destroy the marking, making it unreadable.
Deciphering the alphanumeric code
After you have found the nameplate, you will be presented with a set of symbols that at first glance may seem meaningless. However labeling of Biryusa refrigerators submits to the strict logic laid down by the manufacturer. Typically the code consists of letters and numbers separated by a dash or continuous. Understanding this structure allows you not only to recognize the model, but also to determine the technical characteristics without opening the unit.
A typical code may look like Biryusa 133 KSh-250 or Biryusa 6In the old designations, the letter "K" meant "refrigerator", "Sh" - "cabinet", and the numbers indicated the volume or series. In newer versions, especially those produced after the 2000s, the coding has become more complex and may include information about energy class and defrost type. For example, the presence of the letter "H" at the end of the code often indicates the use of refrigerant R600a (isobutane), which is critically important when repairing the cooling system.
Let's look at the structure using an example conditional code Biryusa 14 KHN-250:
- ❄️ 14 — serial number of the model in the manufacturer’s line.
- ❄️ KH — type of product (refrigerator).
- ❄️ N — type of refrigerant or the presence of additional functions (for example, No Frost).
- ❄️ 250 — useful volume in liters (may vary depending on the series).
It is important to understand that for different decades of production coding system changed. Therefore, the same set of numbers in the 1980 and 2020 models could mean completely different things. For accurate decoding, it is best to check the full code with official catalogs or spare parts databases, where the full specification is indicated.
How to determine the year of manufacture by number
One of the most common questions that arises when searching for a model is determining the age of the equipment. The production date is not always stated explicitly as "Year: 2015", but it is often encoded in the serial number or a separate line on the nameplate. For equipment Biryusa this is especially true, since resources and seals directly depend on the operating time.
On many nameplates there is a line containing a long number series. Often the first two digits of this series indicate the year, and the next two indicate the month of issue. For example, a record 1507000123 may mean that the unit came off the assembly line in July 2015. However, in different periods the plant used different date coding systems. In Soviet times, the date could be stamped with a separate stamp in the form of a dial with an arrow or simply a set of numbers at the end of the line.
If the date on the nameplate is not readable or missing, you can try to determine the age by indirect signs:
- 📅 Refrigerant type: Freon R12 was used until the mid-90s, R134a - from the end 90s to mid-2000s, R600a - in modern models.
- 📅 Design of handles and panels: Plastic handles appeared later than metal ones, touch panels are a sign of recent years.
- 📅 Logo: Brand design Biryusa changed several times, which also helps date the device.
⚠️ Attention: The serial number on the compressor and the number on the refrigerator cabinet may differ. The compressor could have been replaced during a previous repair, so you need to focus specifically on the housing (cabinet) markings.
Why is it important to know the year of manufacture?
Knowing the exact year helps determine which seals and plastic were used. Over time, the composition of the plastic changes, and parts from refrigerators of different years may not be suitable in color or hardness, even if the model is nominally the same.
Series and characteristics correspondence table
To simplify navigation through the model range Biryusa below is a table linking popular series with their key characteristics. This will help you find your way if the complete marking has been erased, but you remember the approximate name of the series or the appearance of the unit.
| Series / Model | Total volume (l) | Type of defrosting | Features |
|---|---|---|---|
| Biryusa 6 (KSh-120) | 120 | Manual | Small-sized, one compressor |
| Biryusa 133 | 250 | Drip | Two-chamber, classic design |
| Biryusa 149 | 300+ | No Frost | System without frost, large freezer |
| Biryusa 355 | 355 | No Frost | Three-chamber, freshness zone |
Using this table, you can roughly identify your unit. For example, if your refrigerator is tall, with two doors and does not require regular defrosting of the freezer, most likely it is a series with a No Frostsystem, such as 149 or 355. If it is a small single-chamber “box” under the countertop, it is almost certainly a series 6 or 8.
When ordering spare parts, always indicate not only the series, but also the full index, if it is available. Within the same series there may be modifications with different compressors or control systems that are externally identical, but technically different.
What to do if the nameplate is lost or unreadable
The situation when the metal plate is irretrievably lost, and the sticker has been erased to zero, is common. Owners often try to wash the camera with abrasives, and the markings disappear. In this case, do not despair, as there are alternative identification methods. The most reliable method is a visual comparison and measurement of dimensions.
You need to take exact measurements of the refrigerator: height, width and depth in millimeters. It is also important to measure the internal dimensions: the depth of the compressor seat, the distance between the evaporator mounting holes. This data, combined with a description of the appearance (color, location of handles, presence of a display), allows service center specialists to select an analogue.
☑️ Actions in case of loss of a nameplate
Additionally, you can take a photo compressor. The engine always has its own marking, which will tell you about the power, type of refrigerant and engine manufacturer. Although this will not provide an exact model of the cabinet, it will narrow the search to a few likely options, since certain compressor models were installed on a limited number of refrigerators.
⚠️ Attention: Specifications and model configurations are subject to change by the manufacturer without prior notice. Always check the visual compliance of the part with your unit before installation.
Where to find information in the documentation
If a physical search on the body does not produce results, you should turn to paper or electronic media. Technical passportgoing included with the refrigerator, contains the exact model on the first page. The serial number of the product is also indicated there. Even if the warranty has expired, it is better to store this document along with receipts for large household appliances.
Also information can be found in purchase and sale agreement or the warranty card, which was filled out by the seller in the store. There the model is spelled out in full, often indicating the article number. If you bought a refrigerator online, check the order history in your personal account of the online store or find an order confirmation letter by email.
For modern "smart" models Biryusaequipped with Wi-Fi modules, information about the model and serial number can be found in the smartphone application, if the device was previously paired with it. In the “About the device” or “Information” section, all factory data is usually duplicated.
How to distinguish the original Biryusa model from a fake or rebranding?
Brand Biryusa is sometimes used to label OEM products (manufactured at other factories on order). The original models of the Krasnoyarsk plant have a characteristic logo and a specific design of plastic elements. Counterfeits or rebrandings may differ in the quality of plastic, compressor noise and availability of spare parts. Always check the country of origin on the nameplate: for the original it will indicate “Russia, Krasnoyarsk.”
Is it possible to restore erased markings?
It is impossible to restore factory markings at home. However, if you know the exact model, you can order a new sticker from authorized dealers or specialized spare parts stores. To do this, you need to provide them with the serial number (if it is saved in the service center database) or accurately describe the characteristics.
Does the color of the refrigerator affect the identification of the model?
Yes, color is often part of the model index. For example, white, silver or patterned (“grapes”, “leaves”) may have different endings in the code. When ordering doors or decorative panels, specifying the color is critical, since shades of white may vary from batch to batch.
Why do you need to know the type of refrigerant when searching for a model?
The type of refrigerant (R12, R134a, R600a) determines the design of the cooling system and the type of oil in the compressor. When making repairs, it is important to know not only the model, but also what it is filled with. Using the wrong refrigerant can damage the compressor. The type of gas is always indicated on the nameplate next to the model.
