Determining the exact production date of household appliances is a task that many owners face when purchasing a used unit, ordering spare parts or contacting a service center. Year of manufacture of the refrigerator is often not indicated on the front panel in an open form, which causes difficulties for users. Manufacturers encrypt this information in special codes, access to which requires knowledge of decryption rules.
Knowing the age of your device is critical to assessing its residual life. Even if your refrigerator looks new, an expired compressor or refrigerant can cause sudden breakdowns. In this article we will analyze search and decoding algorithms serial numbers for the most popular brands.
First of all, you need to find an information sticker or metal plate (nameplate). The location of the marking is always individual for each model and brand, so the search should start with the inner walls of the camera. Most often, manufacturers place all technical information there information, including model and serial number (S/N).
Where to look for the serial number and marking
Searching for identification data is the first step to determining the age of equipment. Manufacturers of household appliances use standardized, but not unified, label placements. Most often, the nameplate can be found on the inner side wall of the refrigerator compartment, closer to the top shelf. This is the most ergonomic place to read data without bending too low.
If there is no information on the side walls of the camera, check the back wall inside the refrigerator. Some brands, such as Indesit or Ariston, prefer to place the stickers there, sometimes hiding them behind plastic elements or egg containers. In rare cases, the label can be found on the base of the unit, behind the vegetable drawer, or on the rear outer wall of the cabinet.
It is important to distinguish the serial number from the model number. The model usually begins with letters (for example, RF, RB, GA) and indicates the type of structure. Serial number (S/N, Serial No) is a unique code containing numbers and letters, which carries information about the date of assembly. Look for lines that say "No.","S/N" or "Serial Number".
⚠️ Attention: Never try to peel off or damage the factory serial number sticker. Lack of readable markings may result in denial of warranty repairs or free service.
Deciphering Samsung and LG codes
South Korean electronics giants use a fairly transparent coding system that is easy to learn. For most models Samsung the serial number consists of 11 characters. The production date is encrypted in the first two characters of the code. The third character usually indicates the manufacturing plant, and the remaining numbers indicate the serial number of the product.
To determine the year and month, pay attention to the first number and letter. The number indicates the year, and the letter indicates the month. For example, in the code 223A... the first two means 2012 or 2022 (the cycle repeats every 10 years), and the second two in combination with a letter can indicate a specific month. However, a format is more often used where the first two digits are the year, and the next two are the month.
The technology LG has a similar logic, but has its own nuances. The first two digits of the serial number contain the year of production. The third and fourth digits indicate the month. For example, the code 1905... indicates May 2019. If the code starts with one digit, for example 9..., this may mean 2009 or 2019, which requires additional analysis or configuration.
Labelling system of Bosch, Siemens and Liebherr
German manufacturers are famous for their pedantry, and their coding system is no exception. Brands Bosch, Siemens i Neff serial number (E-Nr) usually consists of 10 characters separated by dots. However, to determine the production date, you need to look not at the E-Nr, but at a separate code FD (Fabrication Date), which is often located just below or next to it.
The FD code consists of four digits. The first two digits indicate the year of manufacture, but with an amendment: 20 years must be added to the indicated number (for equipment manufactured in the 21st century). The third and fourth digits are the month of production. For example, the code FD 9805 deciphers as follows: 98 minus 20 (or simply changing to a century) gives 2018 (in some old systems 98 meant 1998, but for modern technology the offset rule is relevant), and 05 is May.
Brand Liebherr uses a 14-digit serial number. The production date is encrypted in characters from 2 to 7 inclusive. The format is usually YYMMDD. For example, if these positions are 150620, then the refrigerator was assembled on June 20, 2015. The remaining numbers indicate the time, shift and line number.
What to do if the FD code is not readable?
If the sticker with the FD code is damaged or erased, try to find the documentation for the refrigerator (product passport). The number is often duplicated there, and the date of purchase can be found out by a receipt or warranty card, taking 1-2 months for logistics.
Features of marking Indesit, Ariston and Candy
Italian brands included in the group Whirlpool or Haier, A 16-digit serial number is often used. In this code, the production date is “hidden” in characters from 9 to 14. The first two digits from this sequence (9th and 10th of the general code) indicate the year, the next two - the month, and the last two - the day.
For example, if you have a refrigerator Ariston and in the relevant part of the code you see numbers 231015, this means production date October 15, 2023. This is one of the most understandable systems, since it does not require complex mathematical calculations or knowledge of cycles.
Technology Candy and Zanussi (group Electrolux) may have a different approach. U Electrolux often uses a code of 8 digits, where the first two are the year (for example, 18 - 2018), and the next two are the week of production (not the month!). Thus, the code 1925... means the 25th week of 2019.
How to determine the age of Atlant and Beko refrigerators
Belarusian brand Atlant uses a system where the serial number consists of 9 digits. The production date is encrypted in the last six digits. Format YYMMDD. For example, the number ...210704 indicates that the unit left the assembly line on July 4, 2021. This is a fairly simple scheme, typical for the post-Soviet space.
The Turkish manufacturer Beko uses encoding where the first two digits of the serial number indicate the year, and the next two - the month. However, some newer models use a 10-digit code where the date may be offset. It is recommended to look for a separate line on the nameplate "MFG DATE" (Manufacturing Date), which Beko is often duplicated explicitly next to the serial number.
For brands that are not included in the main lists (for example, Haier, Sharp, Pozis), the "first two digits" rule works in 80% of cases. If the code starts with 21... or 22..., it is highly likely that it is 2021 or 2022, respectively.
Month and year code correspondence table
For ease of decoding, we will provide a summary table that will help compare the alphabetic and digital designations of months used by different manufacturers. Some brands (for example Whirlpool in older models) use letters to designate months.
| Month | Numerical designation | Letter (some brands) | Week code (Electrolux) |
|---|---|---|---|
| January | 01 | A or J | 01-04 |
| February | 02 | B or F | 05-09 |
| March | 03 | C or M | 10-13 |
| April | 04 | D or A | 14-17 |
| May | 05 | E or M | 18-22 |
Please note that letter codes may vary depending on the assembly plant. For example, a letter M can represent both March and May, depending on the specific line Whirlpool. In such cases, it is better to focus on digital values, if they are present in the code.
Service life and diagnostics by date of manufacture
Knowing the exact year of manufacture, you can assess the technical condition of the refrigerator. The average service life of modern compressors is 10-15 years. If your unit is more than 12 years old, you should carefully monitor the operation of the motor and the noise level.
Also, the production date is important when searching for spare parts. Plastic parts, seals and shelves can change design within the same model, but in different years of production (so-called model revisions). When ordering a door or evaporator, be sure to tell the technician the full serial number so that the part fits the fasteners.
☑️ Diagnostics of an old refrigerator
⚠️ Attention: If the refrigerator was manufactured more than 20 years ago, using modern refrigerant during repairs may be impossible or dangerous due to differences in oil and tube materials.
Old models manufactured before 2010 were often used refrigerant R134a or even R12 (freon), which is now prohibited. Modern analogues may not be suitable without completely replacing the system. Therefore, age is a key factor when deciding on repair or disposal.
Is it possible to find out the year of manufacture by model?
Only by model (for example, RB-30) it is impossible to find out the exact year, since the same model can be produced for 5-7 years. However, by the first digits of the article it is sometimes possible to determine the generation or series, which will indirectly indicate the approximate period (for example, “before 2015” or “after 2020”).
What to do if the sticker with the serial number is lost?
If the sticker has been erased or removed, it is extremely difficult to find out the exact date. You can try to find purchase documents. Also, some smart refrigerators store the date of first use in memory, which can be read through the service menu or an application on a smartphone if the device is connected to Wi-Fi.
Does the year of manufacture affect energy consumption?
Yes, significantly. Refrigerators manufactured before 2010-2012 often have energy consumption class A or B. Modern models (after 2015) usually correspond to classes A+, A++ and higher, consuming 30-40% less electricity thanks to inverter compressors and improved insulation.
