When searching for spare parts, issuing a warranty or registering equipment on the manufacturer’s website, the user is often faced with the requirement to indicate the article number. Many people confuse this number with the serial code or model, which leads to errors when ordering unsuitable components. Article is a unique identifier of a specific modification of the device, which contains encoded information about color, type of control, climate class and even country of assembly.
Understanding the difference between serial number and article number is critically important for owners of modern household appliances. If a serial number is assigned to each individual unit on the conveyor to track its life path, then the article designates a group of identical devices with the same set of characteristics. It is by this code that service centers select compatible parts, such as compressors, control modules or door seals.
In this article we will look at where these designations are physically located, how to read complex alphanumeric combinations of popular brands and why it is impossible to select the correct filter or shelf without an exact part number. The article number is often hidden under decorative overlays or on the inside of the drawers, so it is important to know all possible places for its placement. We will analyze the nuances of the marking so that you can confidently navigate the technical documentation.
Where to look for identification data on the refrigerator
The first place you should look when searching marking plate is the interior space of the refrigerator or freezer compartment. Manufacturers often place an information sticker on the side wall so that it is visible when the door is open. However, the location may vary depending on the brand and year of manufacture of the device.
If there is nothing on the inner walls of the camera, carefully inspect the rear outer wall of the case. There is often a metal plate or durable sticker containing all the necessary data, including model, serial number and article number. In some cases, especially with built-in appliances, this information is duplicated on the end of the door or even on the plinth.
⚠️ Attention: Never try to rip off or damage the factory marking plate. The absence or unreadability of this element may become a legal basis for refusal of warranty service, since it will be impossible to identify the device.
For ease of search, we will consider the main locations depending on the type of construction:
- 📍 On the inner side wall of the refrigerator compartment (most often).
- 📍 On the rear outer wall, closer to the top of the case.
- 📍 At the end of the door, hidden behind a decorative plug or hinge.
- 📍 In the niche for the plinth (the bottom panel needs to be removed).
Sometimes The sticker may be partially hidden by shelves or containers. In such cases, it is necessary to temporarily free up space in order to count all the characters without errors. It is important not to confuse the energy class sticker, which is usually brighter and contains less technical information.
Differences between model, part number and serial number
Confusion between these three concepts is the most common mistake when ordering spare parts. Model (Model) is the commercial name of the series, which used in marketing and store catalogues. For example, Bosch KGN39 or LG GA-B. The model unites many devices with a similar design and basic functions, but they may have different article numbers due to differences in color or sales region.
Article number (Article Number, Part Number, PNC) - this is a more detailed code. It points to a specific assembly. Two refrigerators of the same model may differ in the article number if one has a white body and the other has a stainless steel body, or if one is intended for the European market and the other for Asia. It is the article number that determines the compatibility of internal components.
Serial number (Serial Number, S/N) is a unique “passport” of your specific unit. From it you can find out the production date, manufacturer and history of service calls. Unlike the article number, the serial number is not repeated on any other device in the world.
For clarity, let's compare the data structure in the table:
| Parameter | Purpose | Uniqueness | Example |
|---|---|---|---|
| Model | Marketing name of the series | Group | KGN39VI3AR |
| Article (PNC) | Code of specific modification and assembly | Group (for batch) | 941 022 563 |
| Serial number | Identification of a specific instance | Absolutely unique | FD01234567 |
When ordering a part, for example, an electronic module, the master will always ask exactly Product Number or PNC, since the same module can be flashed for different refrigerator articles. Using only the model name here will not guarantee compatibility.
How to decipher the article numbers of popular brands
Each manufacturer uses its own coding system. Understanding the logic of brands Bosch, Electrolux, LG and Samsung will help you quickly determine the origin of the equipment. For German brands, such as Bosch i Siemens, the article is often called E-Nr (product number). It consists of letters and numbers, where the first characters indicate the type of device, and the subsequent ones indicate the modification.
The Swedish concern Electrolux (including brands Zanussi, AEG, Hansa) uses the code PNC (Product Number Code). This is a 9-digit number that is key to selecting any spare parts. The first three digits usually indicate the product type and series, while the rest detail the packaging. A change in even one digit at the end of the PNC may mean a different handle color or refrigerant type.
⚠️ Attention: When searching for spare parts for equipment Electrolux through catalogues, always use the full 9-digit PNC code. Abbreviating or rounding the number will lead to a compatibility error in 90% of cases.
Korean manufacturers LG and Samsung also have their own systems. W LG often there is a model code starting with letters (for example, GA for refrigerators), followed by a set of numbers. Y Samsung the article may be indicated as Model Code and differ from the name visible on the price tag. In documentation, it is often referred to as Ref. No.
Why do codes change?
Manufacturers can change part numbers within the same model when changing the supplier of components (for example, a compressor or thermostat). Therefore, a refrigerator released in January and December of the same year may have different article numbers, although they are externally identical.
For accurate decoding, it is best to use official decoders on the manufacturers' websites or specialized spare parts databases where the full code is entered.
Why do you need an article number when ordering spare parts and repairs
A modern refrigerator is a complex unit in which even outwardly identical parts can have different technical characteristics. For example, the rubber seal (cuff) of the door may differ in thickness or method of fastening depending on the article number of the refrigerator. Ordering by model name often results in the part not fitting into place or the seal being broken.
The article number is especially critical when ordering electronic components: control modules, displays, sensors. The controller firmware is tightly tied to Product Number. Installing a module from a refrigerator with a different article number can lead to incorrect operation of the No Frost system, temperature failures or complete failure of the electronics.
The article is also necessary for:
- 🔧 Accurate selection of glass shelves and plastic containers, the geometry of which changes in different revisions.
- ❄️ Ordering evaporators and condensers, the sizes and power of which vary.
- 📄 Registration of a warranty case from an official representative of the brand.
Service center technicians always require a photo of the nameplate with the article number before starting work. This is an industry standard that allows you to avoid situations where the delivered part does not fit the client equipment.
Typical errors when searching and entering data
One of the most common mistakes is confusion between letters and numbers. Articles often use similar symbols: number 0 and letter O, number 1 and letter I or L. Look carefully at the context: in technical codes the letter O is practically not used to avoid confusion with zero. If in doubt, it is better to enter zero.
The second mistake is ignoring spaces and separators. Some databases require you to enter code strictly without spaces, others - with them. The third mistake is entering the code from the phone keypad, where auto-correction can change the characters. Always double-check the entered line visually.
☑️ Check before ordering spare parts
Users also often look for the article number in the warranty card or receipt. This is the wrong way: in documents, sellers often write only the commercial name of the model, which does not contain the necessary detail for engineers. The source of truth is only the physical sticker on the device.
What to do if the marking is erased or lost
If the nameplate is damaged, dirty or peeled off, restoring the exact part number becomes a task of increased complexity. In some cases, the saved instructions or the box from the device, where the code can be printed on the front side, helps.
If there are no documents, you can try to find the article in the digital memory of the refrigerator itself. On modern models with a display, you can sometimes enter service menu, where PNC or E-Nris displayed. The key combinations for entering the service mode are different for all brands and often require simultaneously pressing several buttons in a certain sequence.
⚠️ Attention: Entering the service menu and changing parameters without knowledge can reset the refrigerator's factory settings. Use this method only to read information without changing the parameter values.
As a last resort, if none of the methods helped, only visual diagnostics by the wizard remains. A specialist will be able to disassemble the unit, find markings on the components themselves (compressor, control board) and determine the modification based on a combination of signs. However, this is a labor-intensive process that does not provide a 100% guarantee.
Is it possible to find an article by serial number?
In most cases, no. The serial number and part number (PNC) are independent identifiers. Manufacturer databases do not always allow a reverse query from S/N to PNC, since one SKU can combine thousands of serial numbers. However, in some corporate databases of large brands (for example, Bosch or Electrolux), technical support can find a connection between them if you contact them officially.
What is the difference between the article for Russia and Europe?
Articles may differ in the presence of additional symbols or numbers indicating the sales region (RUS, EUR). This is due to differences in energy efficiency requirements, type of refrigerant or equipment (for example, availability of instructions in the local language). For spare parts this is often not critical, but for electronic modules the difference can be significant.
Where is the article number for built-in refrigerators?
For built-in appliances, access to the rear wall is often closed by a furniture box. Look for the sticker on the inside edge of the door, behind the plinth trim strip (bottom, near the floor), or on the side wall inside the chamber that will need to be pulled out. Sometimes the code is duplicated in the product passport, which is kept by the owner.
