Determination of the exact production date repairing a household appliance is not just idle curiosity, but often a necessary technical procedure. Knowing the age of the unit is critical when searching for compatible spare parts, since the design of models can change even within the same series. In addition, the service life directly affects the remaining life of the compressor and refrigerant.
Many owners lose the warranty card or receipts in the first year of using the equipment, in which case the serial number becomes the only proof of the date of purchase. It is by this that service centers determine whether the factory warranty is still valid or whether it is time for paid service. Without an exact date, it is impossible to correctly assess the feasibility of repairing an expensive unit.
In this article we will analyze in detail the algorithms for deciphering markings for the most popular brands on the market. You will learn to find hidden signs and understand what the mysterious numbers and letters in the product code mean. This knowledge will help you avoid mistakes when ordering components and correctly assess the technical condition of the device.
Where to look for the serial number on the refrigerator body
The first and most important step is the physical detection of an information sticker or metal nameplate. Manufacturers do not always place them in the same places, guided by the design of a particular model. Most often (label) is located on the inner side wall of the fridge compartment, closer to the shelves, or on the door on the hinge side.
If there is nothing inside the chamber, carefully inspect the back wall of the case where the compressor is located. There may be a silver or white sticker with technical information affixed there. In some models of built-in appliances, the nameplate is hidden on the base or even on the end of the door, hidden by a seal. Look for a line starting with S/N, Serial No or Factory No.
Sometimes the sticker may fade or partially peel off, making the characters difficult to read. In this case, use a flashlight and a magnifying glass to make out the erased marks. An incorrectly read symbol will result in an erroneous decoding of the year of manufacture.
It is important to understand that serial number and model range are different things. The model indicates the type of device, and the serial number is unique for each specific instance and contains information about the date of assembly. Do not confuse this data when entering a request into a spare parts search engine.
Decoding codes for Bosch, Siemens and Liebherr refrigerators
The German engineering school is famous for its pedantry, which reflected in the marking of equipment. For brands Bosch, Siemens and Liebherr the serial number usually consists of 9 or 10 characters. The key role is played by the first two digits of the code, which directly indicate the year of production.
The coding system is quite simple: you need to add 2000 to the first two digits (for models produced in the 21st century). For example, if the number starts with 15, it means the refrigerator was built in 2015. If on 08, then in 2008. This rule works for the vast majority of modern models of these brands.
- 🔹 Code starts with 23 - production in 2023.
- 🔹 Code starts with 19 - device released in 2019.
- 🔹 Code starts with 05 - year of assembly 2005.
- 🔹 The following symbols often indicate the week of production or a specific plant.
⚠️ Attention: For very old models (before 2000) or specific industrial series, the logic may differ. In such cases, the first digits can simply indicate the serial number of the batch, and the year can be encrypted with a letter index at the end of the line.
The Liebherr brand is characterized by the use of long codes, where the year can be duplicated in different parts of the code. If you see a combination of letters FD, the numbers following them often indicate the date. For example, FD 9510 could mean October 2019, where 9 is 2019 (9+2010) and 510 is the week. However, it is easiest to focus on the standard first two digits of S/N. Liebherr is characterized by the use of long codes, where the year can be duplicated in different parts of the cipher. If you see a combination of letters FD, the numbers following them often indicate the date. For example, FD 9510 could mean October 2019, where 9 is 2019 (9+2010) and 510 is the week. However, the easiest way is to focus on the standard first two digits of S/N.
What does the letter at the end of the Bosch code mean?
The letter index at the end of the serial number often indicates the color of the case or the type of handle, rather than the year. For example, E can mean inox (stainless steel), and R can mean white.
Checking the compatibility of spare parts for these brands always requires entering the full number accurately. Even if you know the year, without the full code control module or thermostat may not be suitable, since there could be board revisions within the same year of manufacture.
How to determine the age of Samsung and LG refrigerators
Korean giants Samsung and LG use their own encryption systems, which are a little more complicated than German ones. For Samsung, the serial number is often located on a sticker inside the camera and contains from 15 to 20 characters. The year of manufacture here is encrypted in the form of a single number or letter located in a certain position, usually the eighth or ninth.
If there is a number in the eighth position, 2010 is added to it. For example, the number 5 means 2015. If there is a letter, then the alphabetical encoding is used: A - 2001, B - 2002, and so on, omitting some letters to avoid confusion. However, for modern models, a digital system with a base of 2010 or 2000 is more often used.
The company LG has a similar situation, but the position of the symbol may shift. Often the year is indicated by the first two digits after the model letter prefix. For example, in the code ME45S... the first digits after the letters may be 18, indicating 2018. In other series, the year is coded with a letter: A=2001, B=2002,..., K=2010, L=2011, M=2012 and so on.
- 🔸 The number 9 in the Samsung code often means 2019 (base 2010).
- 🔸 The letter M in LG code corresponds to the year of manufacture.
- 🔸 The letter T in LG encoding is 2019.
- 🔸 Always check the month of manufacture to understand the actual age of use.
⚠️ Attention: Samsung and LG labeling formats may vary depending from the assembly plant (Kaluga, Vladimir, China, Thailand). The same symbol could have different meanings in different years.
To accurately determine the year of Korean appliances, it is best to use the official calculator on the manufacturer’s website or enter the full model number in the search for spare parts. Automatic database systems often know the current decoding schemes better than general tables.
Marking features of Indesit, Ariston and Candy
The Italian group (now part of Whirlpool) uses a fairly transparent system, where the serial number consists of 11 characters. The first digit in the code indicates the year of manufacture. This is one of the simplest rules among all manufacturers. For example, if the number starts with 7, it means the refrigerator was manufactured in 2017.
However, there is a nuance with the decade. The number 1 can mean either 2001 or 2011. Here you need to look at the general appearance of the equipment, the presence of an electronic display or the type of refrigerant. If the refrigerator looks modern, then 1 is 2011 or 2021. The number 0 usually refers to 2010 or 2020. Brands also often use the first digit to indicate the year, but sometimes use a two-digit designation in the middle of the code. For Beko, for example, the third and fourth digits can indicate the year. In the WRE 6511 XAW code, the numbers 11 may mean 2011, but this is not always the case, so it is better to check the correspondence table.
Brands Candy And Beko they also often use the first digit to indicate the year, but sometimes use a two-digit designation in the middle of the code. For Beko, for example, the third and fourth digits can indicate the year. In the WRE 6511 XAW code, the digits 11 may indicate 2011, but this is not always the case, so it is better to check the correspondence table.
| Brand | Position of the year | Code example | Decoding |
|---|---|---|---|
| Indesit | 1st digit | 81234567890 | 2018 |
| Ariston | 1st digit | 90987654321 | 2019 |
| Candy | 1st digit | 76543210987 | 2017 year |
| Beko | 3-4 digits | WRE15... | 2015 |
It is important to consider that older models Indesit and Ariston may have had different encodings until the 2000s. If you see a code starting with 5 or 6 and the refrigerator is clearly old, it could be 1995 or 1996. In such cases, only a visual assessment of the condition of the seals and plastic helps.
Specifics of determining the year for Atlant and Nord refrigerators
The Belarusian brand Atlant (formerly MHM) has its own unique system, which has remained unchanged for a long time. The serial number consists of 7-9 digits. The first two digits indicate the class of the refrigerator, but the third and fourth digits are the year of manufacture. For example, in issue 121600001 the numbers 16 indicate 2016.
For equipment Nord (Zaporozhye plant) the logic is similar, but may vary depending on the decade of production. In modern models, the year is often encrypted in the first two digits or in an alphanumeric code on a sticker. If the number starts with 10, 11, 12, this is 2010, 2011, 2012, respectively.
- ❄️ For Atlant, the numbers 3 and 4 in the code are the year (for example, 109... = 2009).
- ❄️ For Nord, the first two digits are often equal to the year (15... = 2015).
- ❄️ Atlant's production month is usually indicated by the 5th and 6th digits.
- ❄️ The serial number comes after the date.
The peculiarity of the post-Soviet space is that the markings could be applied with paint, which would be wiped off over time. If the numbers on the Atlant nameplate are not readable, try to find a duplicate sticker in the instructions (sometimes sellers paste a copy there) or look for a warranty card where the number was copied manually.
⚠️ Attention: Atlant refrigerators manufactured before 2000 may have had a different coding system. If the third and fourth digits do not follow logic (for example, 99 or 00 in a strange place), perhaps this is a model from the late 90s.
☑️ Check the data before ordering spare parts
Why is it important to know the exact year production
Many users underestimate the importance of the release date, believing that the main thing is the model. However engineering idea it does not stand still. Manufacturers are constantly making changes to the design of even popular models. The type of the compressor, the circuit electronic module, the type of refrigerant (from R134a to R600a) or the design of the evaporator may change.
If you order a part by model, but do not take into account the year, you risk receiving an incompatible item. For example, a thermostat that was installed in 2010 may have a different capillary tube length or mounting type than a similar thermostat that was installed in a 2015 model. This will lead to additional costs of time and money for a return.
Age also affects the diagnosis. If the refrigerator is 15 years old and its compressor fails, it is more economically feasible to buy new equipment than to change the “heart” of the unit. The service life of modern compressors is often lower than that of Soviet or early imported models, but the reliability of the components drops critically by the 15th year of service.
