When purchasing household appliances, issuing a warranty or ordering spare parts, users are often faced with a requirement to provide data from the “nameplate”. This term may seem like jargon, but in fact it refers to the most important information element of any unit. A nameplate is a factory metal or plastic plate on which basic technical information about a specific refrigerator is printed.
It is this data that allows service engineers to accurately identify the model, even if visually it is no different from thousands of others. Unlike the general characteristics of the series, the data on the nameplate is unique to each device. They contain the serial number, date of manufacture, type of refrigerant and power consumption.
The loss or damage of this plate can significantly complicate the life of the owner. Without the exact model code, it is impossible to select a compatible filter, sealing rubber or electronic board. Therefore, knowing what a nameplate is and where it is located is a basic skill for a competent user of complex household appliances.
What is a nameplate and what information does it contain
Technically nameplate (from the German Schild - shield, plate) is a device passport attached to the case. Manufacturers apply information using laser engraving, embossing or permanent printing so that the data is not erased during the entire service life, which can reach 10-15 years. In some cases, this may be a sticker with a protective layer, but metal is considered a more reliable standard.
The surface of the plate usually contains a set of alphanumeric codes and symbols. The most important element is model number (Model Number). It is based on this that the equipment, color, country of assembly and year of manufacture are determined. Often indicated next to Part Number or Product Number, which are used by the logistics systems of factories to track a specific unit.
In addition to identification codes, the nameplate carries critical information for electricians and repairmen. This shows the nominal line voltage, current frequency, power consumption in watts and current strength. These parameters are necessary for the correct selection of a surge protector or voltage stabilizer, especially in conditions of an unstable power supply.
⚠️ Attention: Never try to peel off or re-stick the nameplate to another surface of the case. The adhesive backing often breaks the first time it is removed, and the sign itself may be made of thin metal that breaks easily. If the nameplate is damaged, it will be impossible to restore data on it.
You can also find information about the refrigerant on the nameplate. The type of freon is indicated (for example, R600a or R134a) and its quantity in grams. This information is vital when repairing the cooling system. The technician must know the exact mass of gas for refilling, since a deviation of even 5-10 grams can lead to improper operation of the compressor or the formation of ice in the system.
Where to look for factory markings on different brands
Searching for a nameplate can turn into a quest, since there is no uniform standard for placement. Manufacturers hide the sign in places where it is least exposed to mechanical stress, but is still accessible for reading without dismantling the equipment. Most often, the location depends on the design of the refrigerator compartment and the brand.
In most modern models, especially built-in ones, the nameplate is located on the inner wall of the refrigerator compartment. This can be the left or right side wall, less often - the rear panel. On old Soviet-made models or early imported samples, the plate was often attached to the outside, on the back wall of the case, next to the compressor.
If there is no plate inside the chamber, you should inspect the bottom of the refrigerator. The marking may be on the plinth (lower front), which sometimes needs to be removed, or on the side of the case in the lower third. In some cases, especially with premium brands like Liebherr or Miele, the nameplate is hidden behind a decorative trim on the door or inside the vegetable drawer.
To make your search easier, we suggest focusing on typical placement locations for popular brands:
- 📍 Indesit, Ariston, Hotpoint: Left inner wall of the refrigerator compartment, closer to the ceiling or in the middle.
- 📍 LG, Samsung: Often located on the inner side wall, sometimes covered with a shelf or container.
- 📍 Bosch, Siemens: Right inner wall or side outer wall (you need to move the refrigerator).
- 📍 Atlant, Beko: Internal the wall of the chamber or the space above the top drawer (freezer).
- 📍 Liebherr: Inside the chamber on the right, often under a removable plastic plug.
If a visual search does not produce results, use a flashlight and look in hard-to-reach corners. The nameplate may be silver in color and blend in with the plastic, making it easy to miss in low light.
How to correctly decipher the model code and serial number
The most voluminous part of the nameplate is the line with the model code. It looks like a series of letters and numbers separated by hyphens or spaces. For the average user, this is “Chinese writing,” but for a specialist, this is precise instructions. The model code tells about all the characteristics of the unit.
Usually the code consists of several blocks. The first block represents the series or platform. The second block may indicate the amount of usable space or the type of installation (built-in or free-standing). The third block often encodes the color of the case and the type of control (mechanical or electronic).
Example of code decoding
In the LG GA-B409 SVQL code: GA - series, B - type (low freezer), 40 - height in dm, 9 - width, S - color (silver), V - handle type, Q - country of manufacture, L - refrigerant type.
Serial number (Serial Number or S/N) is a unique identifier. Unlike the model code, which is the same for thousands of refrigerators from the same batch, the serial number is assigned to only one specific device. It is by this that the production date is determined.
The production date is often encrypted inside the serial number or placed in a separate field. Formats can be different:
- 📅 Direct format:
2023.10.15(year, month, day). - 📅 European format:
15/10/23. - 📅 Coded: the first two digits of the year, the next two are the week of production (for example,
2345- 45th week of 2023).
Understanding the release date is necessary to calculate the remaining warranty period. Many manufacturers give a 1-year warranty, but the compressor may have a 10-year warranty. The exact date on the nameplate is the only legal proof of the age of the equipment when contacting service.
Technical parameters: power, refrigerant and energy efficiency class
In addition to identification, the nameplate serves as a source of data on energy consumption. Energy efficiency class (A, A+, A++, B, etc.) indicates the efficiency of the device. However, specific figures for power consumption in kWh per year are more important. They allow you to calculate real energy costs.
A critically important parameter is the type of refrigerant. Modern refrigerators run on isobutane (R600a) or tetrafluoroethane (R134a). These gases are not interchangeable. Using the wrong freon can lead to compressor failure or even fire (in the case of isobutane, which is flammable).
| Parameter | Designation | Meaning for the user |
|---|---|---|
| Refrigerant | Refrigerant / Gas | Gas type for charging (R600a, R134a) |
| Gas mass | Charge / g | Exact number of grams for charging |
| Power | Power / W | Consumption in watts (important for generators) |
| Voltage | Voltage / V | Operating voltage (usually 220-240V) |
| Class | Energy Class | Economy (A++, B and etc.) |
The climate class is also indicated on the nameplate (SN, N, ST, T). It determines the range of ambient temperatures at which the refrigerator can operate efficiently. Violation of this regime, for example, installing a refrigerator class N (normal) in an unheated garage in winter, will lead to thickening of the oil in the compressor and its breakdown.
Why do you need data from the nameplate when ordering spare parts
When a refrigerator breaks down, owners often look for spare parts by appearance or the model name specified in the instructions. This is a big mistake. Within one model line, a manufacturer can use dozens of modifications. They may have different volumes, different positions of handles, but most importantly, different “fillings.”
For example, a thermostat, defrost sensor or fan may look the same, but have different electrical characteristics or wire lengths. The nameplate contains Product Code or PNC (Product Number Code), which allows you to find a part that is compatible specifically with your device revision.
When ordering spare parts through online stores or service centers, you will always be asked for data from the nameplate. Without them, the risk of buying an incompatible part is more than 80%. This is especially true for electronic control modules, where the firmware is tailored to a specific configuration specified in the factory passport.
⚠️ Attention: When ordering spare parts, dictate or write the model code in full, including all letters and numbers after the dash. Even one missing character can direct you to a parts page for a different country or year of manufacture.
In addition, the nameplate helps determine whether the repair is economically feasible. Knowing the exact year of manufacture and model, you can estimate the cost of original spare parts. If the refrigerator is old and the parts are rare, sometimes it is easier to buy new equipment than to look for an original evaporator for a ten-year-old model.
What to do if the nameplate is lost or unreadable
The situation when the nameplate is worn out, peeled off or lost is common, especially with equipment that has been actively used for many years. Without it, accurate identification becomes difficult, but not impossible. However, you should immediately be prepared for the fact that the process will take longer.
The first thing you can do is look for a duplicate sticker. Some manufacturers (for example, Electrolux or Zanussi) glue a copy of the nameplate onto the packaging cardboard or into the warranty card. If you saved the box or documents, the problem is solved.
If there are no documents, you can try to find information on the unit itself. Sometimes a short model code is inked on the back of the case or embossed into the plastic, although this is rare. It is also worth checking the electronic menu (if there is a display): in some models, the firmware or model code can be seen by holding down a certain combination of buttons.
☑️ Actions in case of a lost nameplate
As a last resort, when the nameplate lost, and the model is unknown, craftsmen have to navigate by internal components. A photograph of the compressor, evaporator and electronic board can help an experienced specialist determine the platform on which the refrigerator is assembled and select similar spare parts. But this is always a lottery.
Therefore, if the nameplate is simply hard to read, try gently wiping it with a soft cloth soaked in alcohol. Do not use abrasive powders or solvents, which can permanently destroy the markings.
Frequently asked questions (FAQ)
Is it possible to restore data if the nameplate is completely destroyed?
It is impossible to completely restore the factory markings. However, if the packaging, receipts or service book have been preserved, the data may be there. In some cases, the service center can identify the model by internal software by connecting a diagnostic laptop, but this is a paid and not always available service.
Does the absence of a nameplate affect the warranty?
Yes, the absence of a nameplate or its unreadability is often grounds for refusal of warranty repairs. The manufacturer must be sure that the device has not been modified and is actually manufactured by them. Without a serial number, it is extremely difficult to prove that it belongs to a warranty case.
Where is the nameplate on built-in refrigerators?
On built-in appliances, the nameplate is almost always located inside the refrigeration chamber, on one of the side walls or at the end of the door. It is useless to look for it from the outside, since the building is covered with a furniture facade. It is often hidden behind the decorative strip of the base.
What does the country code on the nameplate mean?
The country code (often a letter at the end or beginning of the model code) indicates the market for which the refrigerator is manufactured. This is important for the compatibility of electrical plugs, menu languages, and sometimes design features (for example, the presence of a loop for the right or left side).
How to find out the production date by serial number?
Each brand has its own coding system. For Samsung and LG, the first digits of the serial number often indicate the year and month. For Bosch and Siemens, the date can be encrypted at the end of the line. For an accurate decoding, it is better to use online calculators on the manufacturer’s website or contact support.
