When choosing a new refrigerator, you probably came across energy efficiency markings - letters from A to G, and sometimes and with the class N. The latter raises the most questions: what is this category, why is it not on the standard scale, and is it worth buying a refrigerator with such a label? In this article we will look in detail at what class Nmeans, how it appeared, how it differs from traditional classes, and what to look for when purchasing.
Since 2021, in Europe and many other countries (including Russia), a new energy efficiency scale for household appliances has been in force, where classes A+++, A++ and A+ were abolished, and instead of them a more strict gradation was introduced from A to G. However, class N is not part of the official classification, but rather a marketing ploy or temporary designation. Most often it can be found on models that have not been certified according to new standards, or on equipment produced before the introduction of current standards. Next, we will tell you why this happens and what it means for the buyer.
What is an energy efficiency class and why is it needed?
An energy efficiency class is an indicator that reflects how efficiently a refrigerator (or other equipment) uses electricity. The higher the class, the less electricity the device consumes at the same power. Until 2021, there was a scale from A+++ (most economical) to D (least economical). A new system is now in effect:
- 🟢 A — the highest level of savings (consumption 50% below average)
- 🟢 B — good energy efficiency (35–50% below average)
- 🟡 C — average (15–35% below average)
- 🟡 D — close to average (at 5–15% below or at the level of the norm)
- 🔴 E, F, G - low energy efficiency (above average consumption)
Class N is not mentioned in this scale, since it is not official. Its appearance is associated with the transition period, when manufacturers did not have time to recertify models to new standards, or with the peculiarities of the markets of some countries. For example, in Russia you can still find refrigerators labeled Nthat actually correspond to class D or E according to the new rules.
Why class N appears: 3 main reasons
Marking N is not accidental - it signals that The refrigerator has not passed official certification according to current standards. Let's consider the main reasons:
- Transition period between standards. From 2021 to 2023, many manufacturers did not have time to reissue documents for their models. During this period, some refrigerators were sold with temporary marking Nwhich was later replaced by D or C after re-certification.
- Import of equipment from countries with other standards. For example, refrigerators released for Asian markets or Middle East may not meet European standards. In this case, they are assigned a class Nto avoid deceiving the buyer (after all, marking F or G could scare off).
- Deliberate understatement of the class to reduce the price. Some brands (especially little-known) do not specifically certify equipment according to the new rules in order to sell it cheaper. In this case N may hide the real class E or F.
It is important to understand that the class N is not a guarantee of poor quality, but rather a sign that the refrigerator has not passed the test latest criteria. However, this does not mean that it will necessarily consume a lot of electricity. For example, some models Indesit or Beko labeled N in practice show consumption comparable to the class C.
Class N vs official classes: comparison table
To understand what to expect when buying a refrigerator with class N, let's compare it with the official categories. Below is a table with approximate energy consumption data for refrigerators with a volume of 200–300 liters:
| Class | Annual consumption (kWh) | Comparison with the average value | Approximate models |
|---|---|---|---|
| A | 100–150 | 50% more economical than average | Samsung RB30A3200SA, LG GB-B399SLQZ |
| B | 150–200 | 35–50% more economical | Bosch KAN90VI20R, Electrolux ERN1200FOX |
| C | 200–250 | 15–35% more economical | Indesit ITS 5180 W, ATLANT XM 4021-000 |
| N (unofficial) | 250–350 | Compliant D or E | Beko CNK 335120, Pozytyv KShD-250 |
| E | 300–400 | 5–15% less economical | Stinol STS 167, Nord NRB 105 |
As can be seen from the table, class refrigerators N usually consume less 20–40% more electricity than class models C. However, the difference in cost can be 10-25%, which makes them attractive to budget buyers. The main thing is remember that class N does not guarantee stability: some models may turn out to be even less economical than class E if the manufacturer has underestimated the data.
Pros and cons of class N refrigerators
Like any equipment with non-standard markings, class refrigerators N have their advantages and disadvantages. Let's look at them in more detail.
Advantages
- 💰 Lower price. As a rule, such models cost 10–30% cheaper than analogs with official classes A–D.
- 🔧 Simple design. Often these are models without unnecessary functions (for example,
No FrostorSmart Control), which simplifies repair and maintenance. - 📦 Wide selection of budget brands. Among class refrigerators N there are many offers from Beko, Pozytyv, Stinol and other brands that are difficult to find in premium categories.
Disadvantages
- ⚡ Increased energy consumption. On average 20–50% higher than in classes C–B.
- 🔊 Higher noise level. Due to simplified cooling system, some models operate louder (up to 45 dB).
- ❓ Unpredictable quality. Lack of certification may mean that the refrigerator has not passed the reliability or safety test.
- 📉 Difficulties with warranty. Some service centers refuse to service equipment without an official energy efficiency class.
If you are considering a refrigerator class N as a temporary solution or a budget option, pay attention to reviews from real customers. For example, the model Beko CNK 335120 with class N is often praised for its spacious freezer, but criticized for uneven cooling in the main chamber. But Pozytyv KShD-250 despite the marking N shows stable operation comparable to the class D.
How to check real power consumption?
If the annual consumption is not indicated in the passport of a Class N refrigerator, you can measure it yourself using a household wattmeter. Connect the refrigerator to the appliance for 24 hours and multiply the result by 365. For example, if it consumed 1.2 kWh per day, then the annual consumption will be ~438 kWh, which corresponds to class E.
How to choose a refrigerator of class N and not regret it
If you still decide to buy a refrigerator with class N, follow these recommendations to minimize risks:
Check the annual energy consumption in the technical data sheet|Study reviews of a specific model on 3-5 independent sites|Check the warranty conditions (are there service centers in your city)|Inspect the refrigerator for mechanical damage (especially the door seal)|Compare the price with class C or D analogues - sometimes the difference is unjustified small-->
Pay attention to the following nuances:
- 🔋 Compressor type. Give preference to models with
inverter compressor—they are quieter and more durable, even if the energy efficiency class is low. - ❄️ Defrosting system.
No Frostis more convenient, but increases energy consumption. If class N, it is better to choose drip defrosting - it is simpler and more reliable. - 📏 Volume of chambers. The larger the refrigerator, the higher its basic energy consumption. For the class N the optimal volume is 200–250 liters.
It is also worth considering climatic conditions. If you live in a region with hot summers (for example, Krasnodar Territory or Crimea), a refrigerator class N may consume 15–20% more than the declared norm due to the increased load on the compressor. In this case, it is better to consider models with a class C or higher, even if they are more expensive.
⚠️ Attention: If a class N refrigerator is sold without a warranty card or with a shortened warranty (less than 12 months), this is a reason to be wary. Perhaps the seller is hiding defects or problems with certification.
Top 3 models of class N refrigerators: review and characteristics
Despite the shortcomings, some class refrigerators N deserve attention due to the price-quality ratio. We analyzed the market and identified three models that are often recommended by buyers.

Frequent problems of class N refrigerators and how to avoid them
Refrigerators with the marking N more often encounter problems associated with savings on components or simplified design. Here are the most common problems and ways to prevent them:
- 🔥 Overheating of the compressor. Due to increased load (especially in summer), the compressor may overheat and shut down. Solution: provide a gap of at least 5 cm between the refrigerator and the wall for ventilation.
- ❄️ Frosting of the back wall. In models with a drip system, ice may form at unstable temperatures. Solution: defrost the refrigerator every 3-4 months.
- 🔊 Increased noise. Cheap compressors often vibrate and hum. Solution: place the refrigerator on a flat surface and adjust the legs.
- 🔌 Power surges. Class refrigerators N are sensitive to changes in electricity. Solution: use a voltage stabilizer.
If the refrigerator begins to operate unstable (for example, it does not turn off or does not cool enough), check:
- The room temperature (optimally - 16–32°C).
- Closing tightness doors (the seal should not be damaged).
- Loading of the chambers (do not overload the shelves, especially in the freezer).
⚠️ Attention: If a class N refrigerator after purchase consumes 30% more electricity than indicated in the passport, this may be a sign of a manufacturing defect. In this case, contact the service center during the warranty period.
FAQ: Frequently asked questions about N-class refrigerators
