When buying a refrigerator LG you probably paid attention to the mysterious combinations of letters and numbers in the model name - for example, GA-B409SQDL or GR-N309SLQZ. These symbols were not just invented by the manufacturer: they encode the key characteristics of the equipment, from dimensions to the type of defrosting. Understanding the logic of the labeling, you can quickly determine whether the model suits your needs, even before studying the technical data sheet.
In this article we will look in detail at how each letter and number in the names of refrigerators is deciphered LG, what series exist and what to look for when choosing. We will pay special attention to energy efficiency, compressor type and cooling systems —parameters that directly affect the cost of operation and ease of use. If you are planning a repair or modernization, knowledge of the markings will help you select compatible spare parts without the risk of error.
Marking structure: what the letters and numbers mean
The name of any refrigerator model LG consists of 8–10 characters, divided into logical blocks. Let's look at the general template using the example of a model GR-B247JVQA:
| Position | Characters | Value | Example |
|---|---|---|---|
| 1–2 | Letters | Series refrigerator | GR — series with system DoorCooling+ |
| 3 | Letter | Refrigerator type | B —two-chamber |
| 4–6 | Numbers | Total volume (in liters) | 247 — 247 l |
| 7 | Letter | Design and color | J — silver (Inox) |
| 8–10 | Letters/numbers | Technical features | VQA —inverter compressor, class A+++ |
The first two characters (GR, GA, GB etc.) indicate series, which determines the set of functions. For example, the series GA is models with the system Multi Air Flow for uniform distribution of cold air, and GR equipped with technology DoorCooling+that cools food faster on the door. The third letter reveals design: B a two-chamber, S — Side-by-Side, M - chest freezer.
The digital block (for example, 247) indicates usable volume in liters, but there is a nuance here: for some series (for example, Side-by-Side) the first digit may indicate width in inches. The last characters (VQA, SLQZ) encode energy class, the type of compressor and additional options such as an ice maker or touch control.
Deciphering LG refrigerator series: from budget to premium
The manufacturer divides its products into series, each of which is focused on specific tasks and budgets. Below are the key series that are relevant for the market in 2026–2026:
- 🔹 GA — basic series with a system Multi Air FlowSuitable for small kitchens, equipped with mechanical controls and energy consumption class A+.
- 🔹 GB —an improved version GA with electronic control and function Smart Diagnosis for quick diagnosis of faults.
- 🔹 GR —a premium series with technology DoorCooling+that cools products on the door 32% faster. Includes models with inverter units. compressors and class A+++.
- 🔹 GS — Side-by-Side with an ice generator and water dispenser. Volume from 500 liters, equipped with a system Total No Frost.
- 🔹 GC - compact models with a height of up to 150 cm, ideal for offices or small families. Class A++.
Series. data-i="115">and GR And GS are considered flagship and are equipped linear inverter compressors, which consume 30-40% less electricity compared to traditional ones. In the budget series (GA, GB) standard compressors are used, but with a function Smart Inverter, which smoothly regulates power.
⚠️ Attention: In 2023 LG updated the line Side-by-Sideby adding models with the function UVnano for air disinfection. If this option is important to you, check the presence of the symbol N at the end of the marking (for example, GS-X609NSVZ).
Types of refrigerators by design: how to determine by marking
The third letter in the model name indicates design - two-chamber (freezer at the bottom). Example: the refrigerator. This is critical when choosing, since not only the appearance, but also the functionality depends on the type:
- 📏 B — two-chamber (freezer at the bottom). The most popular option for families of 3-4 people. Example: GA-B409SQDL.
- 📏 S — Side-by-Side (two doors vertically). series GS-X609NSVZ.
- 📏 M — chest freezer (without refrigeration chamber). Used for long-term storage. Example: GM-F247SLQZ.
- 📏 T — single-chamber (refrigerator compartment only). Rarely found, usually in series GC.
- 📏 F —French door (two-chamber with two doors for a refrigerator). Example: GF-L609PLCY.
For Side-by-Side (S) and models with a French door (F) the marking may contain a letter X before the volume numbers - this indicates the width of the case. For example, GS-X609 means a width of 60 inches (about 152 cm).
If you need a refrigerator with ice maker, look for the letter at the end of the marking I (for example, GS-X609NSVI). For models with water dispenser add W (GS-X609NSVW). These options are only available in series GS and GF.
Energy consumption class: how to save on electricity
The energy efficiency of the refrigerator directly affects your utility bills. In the marking LG the class is indicated by letters at the end of the model name:
- ☀️ A+++ —the most economical (consumption is 20–30% lower than that of A+). Marking: VQA, VQZ.
- ☀️ A++ —high class, suitable for round-the-clock operation. Marking: SQA, SLQ.
- ☀️ A+ —standard for budget models. Marking: JQA, JLQ.
- ☀️ A —obsolete class, found in models before 2018. Marking: QA, LQ.
For example: a model GR-B247JVQA has a class A+++ (designation VQA), and GA-B409SQDL a class A++ (SQD). The difference in electricity consumption between these classes can reach 150–200 kWh per year with the same volume.
Since 2021 LG switched to a new energy efficiency scale (from A to G), but the old designations are still used in marking models (A+++, A++). To find out the exact class according to the new standard, check the sticker on the case or the technical data sheet.
⚠️ Attention: If the marking contains a letter E (for example, GA-B409SEQDL), this indicates the presence of a function Eco Modethat further reduces energy consumption by 10-15% by optimizing operation compressor.
Types of compressors: inverter vs standard
The compressor is the “heart” of the refrigerator, and its type determines noise, durability and efficiency. In the marking LG this is reflected in the last symbols:
- ⚙️ V —linear inverter compressor (Linear Inverter). The quietest (up to 38 dB) and durable (10-year warranty). Example: GR-B247JVQA.
- ⚙️ S —standard inverter (Smart Inverter). Moderate noise (40-42 dB), 5 year warranty. Example: GA-B409SQDL.
- ⚙️ J — a regular compressor (not an inverter). Noise is 43–45 dB, found in budget models. Example: GB-B249JLQZ.
Linear inverter compressors (V) are used in premium series (GR, GS) and are characterized by smooth power control. This allows you to maintain the temperature with an accuracy of ±0.5°C, which is critical for storing perishable products. Standard inverter (S) are cheaper, but less accurate (±1°C).
If the marking contains a letter T (for example, GR-B247JVTQA), this means the presence of double compressor - separate for refrigeration and freezers. Such models are more expensive, but allow you to independently regulate the temperature in each zone.
How to check the type of compressor without marking?
If you already have a refrigerator LG, but you are not sure about the type of compressor, do the following steps:
1. Unplug the refrigerator.
2. Remove the back cover (a Phillips screwdriver is required).
3. Look at the compressor sticker:
- Inscription Linear Compressor - linear inverter.
- Inscription Inverter Compressor - standard inverter.
- Absence words Inverter —an ordinary compressor.
Defrosting systems: No Frost, Total No Frost and others
The type of defrosting system affects the care of the refrigerator and the uniformity of cooling. In the marking LG this is not always indicated explicitly, but can be determined by the series and additional symbols:
- ❄️ Total No Frost — complete absence of frost in both chambers. Used in series GR, GS, GF. The marking may contain a letter N (for example, GR-B247JVQN).
- ❄️ Frost Free - automatic defrosting of the freezer compartment only. The refrigerator compartment requires manual defrosting 1-2 times a year. Found in series GA, GB.
- ❄️ Direct Cool - manual defrosting (drip system). The most budget option, is marked with a letter D at the end (for example, GA-B409SQD).
The system Total No Frost assumes the presence of fans that evenly distribute cold air, preventing the formation of ice. However, such models consume 5-10% more electricity due to the operation of the fans. Direct Cool, on the contrary, it is more energy efficient, but requires regular maintenance.
If the marking contains a combination of SL (for example, GA-B409SLQZ), this indicates a system Smart Cooling - a hybrid No Frost and drip defrosting, where the fans only work when opened doors.
- Do you need minimal maintenance? → Total No Frost
- Is energy saving important? → Direct Cool or Smart Cooling
- Refrigerator for the dacha (rare use)? → Frost Free
- Mold allergy? → Total No Frost with Plasma filter

Additional functions: what do the last characters hide
Last 2–3 symbol in the marking (VQA, SLQZ etc.) encode additional options. Let's decipher the most useful ones:
- 🔋 Q - function Smart Diagnosis (fault diagnosis via a mobile application).
- 🔋 L - backlight LED (instead of incandescent lamps).
- 🔋 P — Plasma filter for air purification.
- 🔋 I — ice maker (Ice Maker).
- 🔋 W — water dispenser.
- 🔋 E — mode Eco Mode.
- 🔋 N —technology UVnano (disinfection with UV rays).
- 🔋 Z —touch control.
For example, the model GR-B247JVQZ is equipped with:
- Inverter compressor (V),
- Function Smart Diagnosis (Q),
- Touch control (Z).
If there is a letter at the end of the marking D (for example, GA-B409SQDL), this indicates the presence an additional compartment for fresh food (Fresh Converter, where the temperature is separately regulated (from +1°C to +5°C).
⚠️ Attention: Functions Ice Maker (I) and Water Dispenser (W) require connection to plumbing. If your kitchen does not have this option, choose models without these symbols in the marking.
FAQ: Frequently asked questions about the labeling of LG refrigerators
How to determine the year of manufacture of an LG refrigerator by marking?
The year of manufacture is not indicated in the main marking of the model, but it can be found out by serial number (located on the nameplate on the back of the refrigerator). The first two digits of the serial number usually indicate the year of manufacture. For example, 2305... — May 2023.
What does the letter mean C at the beginning of the marking (for example, GC-B249SLQZ)?
Letter C denotes a compact model (height up to 150 cm). Such refrigerators usually have a volume of up to 250 liters and are suitable for small kitchens or offices.
Is it possible to determine the noise level of a refrigerator by the markings?
Directly - no, but indirectly - yes. (V in the marking) have a noise level of 38–40 dB. Standard inverter compressors (S) are 40–42 dB, and conventional compressors (J) are 43–45 dB. The exact noise value is indicated in the technical data sheet.
What to do if the marking contains unknown characters (for example, GR-B247JVQX)?
Letter X or other non-standard symbols may indicate a limited series or regional modifications (for example, for the Asian or European market). In this case, check the technical data sheet or check with the seller.
As for marking understand whether the refrigerator is suitable for built-in?
Built-in models LG have the letter I in second place (for example, GI-B249SLQZThey are also usually marked as Built-in in catalogs). manufacturer.
