Many owners of household appliances are faced with situation when accurate information about the model or release date is required, and paper documents have long been lost. Refrigerator Passport is not just a stack of paper with instructions, but the main legal and technical identifier of your device. It is this document that confirms ownership, contains a wiring diagram, refrigerant parameters and warranty service conditions.
In the modern world, where digital service centers require accurate data to select spare parts, the lack of a passport can turn a minor repair into a long quest to find analogues. Users often confuse a warranty card and a technical passport, although these are different documents with completely different functions. Understanding what exactly to look for and where to look for it will save you hours of time when communicating with support.
In this article we will look in detail at what a passport looks like, how it differs from the sticker on the case and where to look serial numberif the paper medium is lost irretrievably. You will also learn how to correctly read complex technical specifications so as not to make mistakes when ordering filters or compressors.
The difference between a technical passport and a warranty card
The first thing you need to understand: a technical passport and a warranty card are two different documents, although in stores they are often issued in one folder. Technical passport (or manual) contains a description of the device, circuit diagrams, compatibility tables, power consumption parameters and error codes. It is “tied” to the refrigerator model and does not change from copy to copy, except for the page with an individual number.
The warranty card, on the contrary, is an individual document confirming the fact of purchasing this particular unit in a specific store on a certain date. Without the seller's stamp and the date on the warranty card, the service center has every right to refuse free repairs, even if you have a complete technical passport in your hands. At the same time, the passport itself often contains a section “Certificate of Acceptance”, which also requires certification.
If you plan to sell a used refrigerator, having a full set of documents, including a passport, increases the liquidity of the product. Buyers are more willing to buy equipment that comes with diagrams, as this indicates the previous owner’s careful attitude towards the property. The absence of documents is often regarded as a signal of possible hidden problems or handicraft repairs in the past. original instructions with diagrams, as this indicates the previous owner’s careful attitude towards the property. The lack of documents is often regarded as a signal of possible hidden problems or makeshift repairs in the past.
⚠️ Attention: When purchasing a refrigerator second-hand, be sure to check the serial number on the back wall with the number indicated in the technical passport. A discrepancy may mean that the device is assembled from parts of different units or is listed as stolen.
Where to find the serial number and model on the case
The most reliable way to identify a refrigerator is to find the factory markings. Manufacturers place information plates (stickers or metal plates) in specific locations to make data easier to access without having to move heavy equipment. Most often label located inside the refrigerator compartment: on the left or right side wall, less often - on the inside of the door or on the ceiling of the chamber.
If there is no sticker inside the chamber, carefully inspect the back wall of the device. A metal plate with embossed data or a heat-resistant sticker is often placed there. On modern models built-in refrigerators the marking may be located on the end of the door, visible only when it is opened. In some cases, especially in old Soviet models, the data was duplicated on the base grille near the compressor.
What exactly to look for? You are interested in the line Model or Mod. (model) and Serial No or S/N (serial number). The model usually looks like a set of letters and numbers, for example ATLANT XM-4008-022. The serial number may be longer and contain information about the production date encoded in the first characters. Knowing this data, you can find a digital passport on the manufacturer's website.
Structure and content of the technical passport
The classic paper refrigerator passport consists of several mandatory sections, each of which contains critical information for operation and repair. Understanding the structure of this document will help you quickly find the information you need without having to read through hundreds of pages of text. The main sections are standardized by international safety standards for household appliances.
At the beginning of the document there is always a “Safety Precautions” section, followed by a description of the device and operating principle. Particular attention should be paid to the “Technical Specifications” section, which provides precise data on power consumption, chamber volume, climate class and type of refrigerant used. For repairmen, the most important section is with diagrams electrical circuits and operation cyclogram.
- 📄 General information: purpose of the device, operating conditions, climate class.
- ⚙️ Technical data: dimensions, weight, usable space volume, compressor power.
- ❄️ Refrigerant: type of freon (R600a, R134a) and its exact charge in grams.
- 🔌 Electrical parameters: voltage, current frequency, consumption power.
- 🛠️ Schemes: electrical circuit diagram and refrigeration circuit diagram.
The section dedicated to transportationdeserves special attention. It clearly states at what angle and for how long the unit can be transported, as well as how long after installation it can be turned on. Violation of these recommendations specified in the passport is a common cause of compressor failure in the first months of operation.
Why are different weights indicated in the passport?
The technical passport often indicates “net” (weight of the device itself) and “gross” (weight with packaging). To calculate the load on a shelf or elevator, use the net weight, and to order loader services, use the gross weight.
Table of main parameters in the passport
For quick reference in the technical specifications, it is convenient to use a summary table. This data is usually placed on the first page of the passport or on a separate insert. Below is a table with typical parameters that you will find in the documentation for a modern two-chamber refrigerator.
| Parameter | Designation in the passport | Typical value | Unit of measurement |
|---|---|---|---|
| Total volume | Total Volume | 300 - 350 | liter (l) |
| Compressor power | Power / Input | 100 - 150 | Watt (W) |
| Refrigerant type | Refrigerant | R600a / R134a | - |
| Charge refrigerant | Charge | 40 - 60 | grams (g) |
| Climate class | Climate Class | SN-T | - |
Pay attention to the column "Refrigerant charge". This critically important parameter for masters: even a deviation of 5-10 grams from the passport value can disrupt the operation of the No Frost system or lead to freezing of the evaporator. Never fill the refrigerator “by eye”; always check the passport.
The climate class indicated in the table determines the ambient temperature range in which the refrigerator is guaranteed to operate correctly. For example, class SN-T means that the device is adapted for operation in rooms with temperatures from +10°C to +43°C. Installing such a refrigerator in an unheated garage in winter or in the kitchen next to a hot stove can lead to premature wear.
Digital passport and searching for documentation online
In the era of digitalization, paper passports are often lost, but manufacturers have provided the possibility of restoring information. Most large brands, such as LG, Samsung, Bosch, Indesitkeep documentation archives on their official websites. To search, you will need the exact model of the device, which we learned to find on the nameplate.
The search process usually looks like this: you go to the manufacturer’s official website, find the “Support” or “Service” section, enter the model in the search bar and go to the product card. There, in the "Documents" or "Downloads" section, it is available PDF file with a complete technical data sheet and user instructions. This file is legally equivalent to the paper original.
If the document is not found on the manufacturer’s website (which happens with models older than 10 years), you can use specialized databases manualslib or similar sites. However, in this case you need to be careful: make sure that the modification in the file completely matches yours, since one model may have different versions (for example, with a different color or type of handle), and control schemes may differ.
⚠️ Attention: Download passports only from the official websites of manufacturers or trusted resources. Files from unverified sources may contain viruses or incorrect technical information, which is dangerous when carrying out repairs.
Why do you need a passport for repairs and warranty service
When the refrigerator fails, the technical passport becomes the main tool of communication between the owner and the service center. Customer service agents always start the conversation by asking, “What is your model and serial number?” Without this data, they cannot submit a claim or provide advice on the error codes that are displayed on the display.
For warranty repairs, a passport (or a digital copy thereof) and a purchase receipt are required. The service center checks not only the fact of the breakdown, but also the operating conditions. If the passport indicates that the refrigerator is intended for temperate climates, but you used it in the tropics, the warranty may be denied. Also, a passport is needed to confirm that the breakdown is not caused by power surges if the device does not have appropriate protection.
For post-warranty repairs, a passport is needed to select original spare parts. Compressors, control boards, door seals - all these parts have catalog numbers tied to a specific modification of the refrigerator. Using analogs without checking with technical specifications can lead to incorrect operation of the unit.

Frequently asked questions (FAQ)
Is it possible to restore a refrigerator passport if it is lost?
It is impossible to completely restore the original paper passport with a store seal. However, you can download the official electronic version of the instructions and technical description from the manufacturer’s website for the model. For a warranty case, the loss of your passport is not a problem if you still have a receipt or bank account statement confirming the purchase.
Where is the serial number if the sticker inside the chamber is worn off?
If the internal sticker is not readable, look for the label on the back wall of the refrigerator (a metal plate or sticker near the compressor). Also, a duplicate of the data is often glued to the packaging cardboard (if it is saved) or stamped on the compressor housing (although the number there may differ from the serial number of the refrigerator itself).
Why is the number of grams of freon indicated in the passport?
The exact amount of refrigerant (for example, 52 grams of R600a) is necessary for high-quality refilling at repair. Modern environmentally friendly freons require high dosage accuracy. An excess or lack of gas disrupts the cooling cycle, increases the load on the compressor and can lead to its breakdown.
Is a photo of a passport in the phone a document for guarantee?
For an initial consultation by phone or via support chat - yes, a photo is enough. However, to complete an official application for warranty repairs, the service center may require original documents or their certified copies. It is better to always have a receipt and a completed warranty card with you.
