When you open the refrigerator to When you get frozen berries or a package of dumplings, you rarely think about how the freezer inside works. Meanwhile, its design directly affects ease of use, energy efficiency and even shelf life of products. A freezer is not just a “cold compartment”, but a complex system with its own technical nuances, which differ depending on the model of the refrigerator.
In this article we will look at what a freezer looks like in a refrigerator of different types: from classic Soviet units to modern No Frost and Side-by-Side. You will learn what types of freezers there are by location (top, bottom, side), what materials the shelves and drawers are made of, and why some models are equipped and others are not. We will also compare the pros and cons of each type of design to make it easier for you to choose the best option when buying a new refrigerator or remodeling your kitchen. fresh frozen zones, while others do not. We will also compare the pros and cons of each type of design to make it easier for you to choose the best option when buying a new refrigerator or remodeling your kitchen.
Types of freezers by location in the refrigerator
The first thing that catches your eye when choosing a refrigerator is where exactly the freezer is located. Its location determines not only ease of access, but also the distribution of cold air inside the unit. Let's consider the main options:
- 📦 Top freezer —the classic option, which is found in most budget and mid-price models (ATLANT, Biryusa, Indesit). The freezer occupies the upper third or half of the refrigerator, and the main cooling compartment is located below.
- 📦 Bottom freezer is a popular solution in modern refrigerators (Samsung, LG, Beko). The freezer is located at the bottom, which is considered more ergonomic: there is no need to bend over for frequently used products (dairy products, vegetables), and frozen supplies are usually required less frequently.
- 📦 Side-by-Side freezer - typical for large-sized premium refrigerators (Liehberr, Bosch Serie 8). The freezer and refrigerator compartments are located side by side, like two vertical doors. This format is convenient for large families or those who store a lot of frozen food.
- 📦 Free-standing freezer - used as an addition to the main refrigerator. It can be vertical (cabinet) or horizontal (chest). Popular brands: Nord, Snaige, Vestfrost.
Each type has its own advantages. For example, top freezer cheaper to produce and less often requires defrosting (warm air rises up and cold air remains down). A Side-by-Side allows you to store more food, but takes up a lot of space and consumes more electricity.
Freezer structure: what it consists of and how it works
Externally, the freezer may look like a simple box with shelves, but inside it hides a whole complex of parts responsible for maintaining a low temperature. Main elements:
- ❄️ Evaporator —a metal panel (usually aluminum), where the refrigerant (freon) boils and takes away heat. In models with No Frost the evaporator is hidden behind the back wall, in drip models it is located openly.
- 🌀 Fan is present in systems No Frost and Frost Free. It evenly distributes cold air throughout the chamber, preventing the formation of ice.
- 📦 Shelves and containers — made of impact-resistant plastic or tempered glass. Some models (Liehberr) use retractable metal drawers with antibacterial coating.
- 🔄 Drainage system —a tube for draining melt water (in drip systems) or condensate (in No Frost).
- 🌡️ Temperature sensor — controls the operating mode of the compressor. In advanced models (Samsung Twin Cooling Plusthere may be several sensors for different zones.
V in freezers with a No Frost system, the evaporator is never covered with ice due to forced air circulation, but such models consume 10-15% more electricity (or drip. "crying") freezers, ice forms, but automatically thaws when the compressor is turned off. However, they need to be defrosted manually 1-2 times a year.
Why ice forms in the freezer, even if it is No Frost?
Even in No Frost systems, ice can appear if the door remains ajar for a long time, the seal is worn out, or too much wet food is stored in the chamber (for example, unpacked soups or berries). The fan cannot remove moisture, and it crystallizes on the walls.
| Freezer type | Advantages | Disadvantages | Example brands |
|---|---|---|---|
| Drip (manual defrosting) | Low energy consumption, quiet operation, long service life | Requires manual defrosting, ice accumulates | ATLANT, Biryusa, Stinol |
| No Frost (automatic defrosting) | No need to defrost, uniform cooling, fast freezing | More noisy, more expensive to repair, takes up useful space volume | Samsung, LG, Bosch |
| Frost Free (combined) | No Frost freezer, drip refrigeration compartment | More difficult to repair, high price | Indesit, Beko, Electrolux |
| Low Frost (improved drip) | Less ice, requires defrosting less often | Still needs to be defrosted, but less often | Liehberr, Gorenje |
Materials and design of shelves in the freezer
Not only their strength, but also their convenience depends on what the shelves and containers in the freezer are made of operation. Manufacturers use different materials:
- 🧊 Plastic —the most common option. Lightweight, does not rust, but can become brittle at low temperatures (below -18°C). In budget models (Indesit, ATLANT), the plastic is thin and can crack upon impact.
- 🥶 Hardened. glass - stronger than plastic, can withstand weight up to 20-30 kg, resistant to scratches. Used in premium refrigerators (Liehberr, Bosch Serie 8). Minus - heavier than plastic and can break if dropped.
- 🛠️ Metal grilles —found in free-standing chest freezers or professional models. They can withstand heavy weight, but can rust when in contact with moisture.
- 🧴 Plastic with antibacterial coating —used in models with function BioFresh (Liehberr) or FreshZone (Samsung). The coating prevents the growth of bacteria.
The design of the shelves also varies:
- 📦 Fixed shelves —they are rigidly fixed to the walls of the chamber. Inconvenient to clean, but reliable.
- 🔄 Drawers - convenient for storing small products (berries, dumplings). In some models (Samsung RB37J5240), the drawers have sealed lids.
- 🧊 Shelves with sides —prevent products from falling out when the door is opened.
- 🍎 Specialized compartments —for example fresh frozen zone (-7°C) for meat or fish before long-term storage.
What does the freezer look like inside: photo and description of zones
The appearance of the freezer depends on its type and brand. Here's what you'll usually see inside:
1. Back wall:
- B No Frost - smooth, with ventilation holes.
- In drip models - ribbed (evaporator), can be covered with ice.
- In some refrigerators (Liehberr) the back wall is made of stainless steel for better distribution cold.
2. Side walls:
- Most often smooth, with grooves for shelves.
- In models with dynamic cooling (Samsung Twin Cooling) there may be additional ventilation ducts.
3. Freezer door:
- Equipped with shelves for small products (ice, packages of sauces).
- In some refrigerators (LG Instaview) the door has a transparent insert for quickly viewing the contents without opening.
- The sealing rubber must fit tightly - if it is torn, the freezer will freeze.
4. Lighting:
- In budget models - one incandescent light bulb.
- In premium models - LED backlight (Bosch VitaFresh), which turns on automatically when opened.

What is the SuperFreezing zone?
This is a special compartment in the freezer where the temperature drops to –32°C for blast freezing. Used for quick freezing of fresh foods (meat, fish, berries) without loss of taste. After freezing, the temperature automatically returns to standard (–18°C).
How to properly organize space in the freezer
Even the most spacious one. the freezer may seem cramped if the food is arranged chaotically. Here are some tips for organization:
- 📦 Use containers:
- Transparent plastic boxes with lids (IKEA 365+, Tupperware) allow you to quickly find the products you need.
- Label the containers. with the date of freezing (the maximum shelf life of most products is 6–12 months).
- 🧊 Separate products into zones:
- Top shelves: frequently used products (ice, semi-finished products).
- Middle shelves: meat, fish, poultry.
- Bottom drawers: vegetables, fruits, berries.
- Door: small packages (sauces, greens in bags).
- ❄️ Do not overload the freezer:
- There should be space between products for air circulation.
- Optimal load - 70–80% of the volume.
- 🔄 Inspect regularly:
- Once every 2-3 months, check expiration dates and throw away expired products.
- Defrost freezer (if not No Frost) when ice forms thicker than 5 mm.
☑️ Checklist for organizing the freezer
If your freezer does not have built-in drawers, buy organizers for the freezer —they will help divide the space and avoid clutter. It is also useful to use vacuum packages for long-term storage of meat or fish: they prevent burns from the cold and save space.
⚠️ Attention: Do not store food in the freezer in glass jars (they may burst) or aluminum foil (it oxidizes at low temperatures). For liquids (soups, juices), use plastic containers with a volume reserve of 10-15%, since liquid expands when frozen.
Frequent problems with the freezer and their causes
If the freezer is not working properly, this can lead to food spoilage or increased energy consumption. Let's consider typical malfunctions and their possible causes:
| Problem | Possible causes | Solution |
|---|---|---|
| The freezer does not freeze | The compressor has failed, freon is leaking, the thermostat is faulty, the capillary tube is clogged | You can independently check whether the refrigerator is plugged in and not connected. Is the power cord damaged? |
| Formation of a thick layer of ice | Malfunction of the defrost system (in No Frost), the seal is damaged, the door often opens | Defreeze the freezer, check the seal, if necessary replace. No Frost the defrost heating element may need to be replaced. |
| The freezer is very noisy | Fan wear (in No Frost), vibration of the compressor, foreign object getting into the mechanism | Check whether the refrigerator is touching the walls or furniture. If the noise does not go away, call a specialist. |
| The temperature is too low (food freezes) | The thermostat is faulty, the mode switching valve is stuck, there is an error in the electronic unit | Try to reset the settings to factory ones. If this does not help, repair the thermostat or control board. |
| Ice on food | Frequent opening of the door, storage of unsealed products, seal failure | Check the tightness of the packages, replace the seal, defrost the chamber. |
⚠️ Attention: If the freezer stops working after a power outage, do not rush to call a technician. Wait 10-15 minutes - the compressor may need time to start. If after an hour the freezer does not start cooling, check the fuses in the panel.
In models with electronic control. (Samsung, LG) a malfunction can be indicated by error code on the display. For example:
- 🔴
E1orF1- a problem with the temperature sensor. - 🔴
E4orF4- malfunction of the defrost system. - 🔴
E5- freon leak.
Deciphering the error code can be found in the instructions for the refrigerator. If you don’t have it at hand, try searching for the refrigerator model and error code on the Internet.
FAQ: Frequently asked questions about freezers
❓ Why does ice form in the freezer, even if it is No Frost?
In systems No Frost ice can appear for several reasons:
- Door The freezer does not close well (the seal is worn out or the product is in the way).
- Warm, humid air enters the chamber (for example, if you often open the door or store loosely packaged liquid products).
- The defrost heater or defrost timer is faulty.
Solution: check seal, defrost the freezer and wipe dry. If ice appears again, call a technician to diagnose the system. No Frost.
❓ What temperature should be in the freezer?
The optimal temperature for long-term storage of food is –18°CHowever, in some modes it may differ:
- 🥩 Blast freezing (for meat, fish): –24°C to –32°C.
- 🍓 Fresh frozen zone (for berries, greens): -7°C to -12°C.
- ❄️ Super Freeze mode (quick freezing): –24°C (on for 24–48 hours).
The temperature can be adjusted using a mechanical thermostat or electronic panel (depending on the model).
❓ Yes Is it possible to store glass jars in the freezer?
No, glass jars (especially those with liquid) not store in the freezer. When frozen, the liquid expands and the jar may burst. To store soups, sauces or berries, use:
- Plastic containers with lids (for example, Tupperware).
- Special freezer bags with a zip fastener.
- Silicone ice molds (for small servings).
If you need to freeze liquid in a glass container, leave free space (10-15% of the volume) and use heat-resistant glass (for example, Pyrex).
❓ How often do you need to defrost the freezer with No Frost?
Freezers with the system No Frost do not require regular defrosting, but 1-2 times a year they are still recommended:
- Disconnect from the network and take everything out products.
- Rinse the internal surfaces with warm water and soda (1 tablespoon per 1 liter of water).
- Wipe dry and ventilate for 1-2 hours.
This will help eliminate unpleasant odors and prevent the growth of bacteria. Defrosting is also necessary. if:
- The freezer began to make a lot of noise.
- Ice appeared on the walls (this is a sign of a malfunction).
- After a power outage.
❓ Why does the freezer work, but the refrigerator does not?
If the freezer compartment freezes, but the refrigerator compartment does not cool, the reasons may be as follows:
- 🔌 The fan (in models with No Frost), which distributes the cold between the chambers.
- 🧊 The damperis faulty, regulating the air flow between compartments.
- 🌡️ The temperature sensor of the refrigerator compartment is jammed.
- ❄️ Freon leak in the circuit of the refrigerator compartment has failed (the freezer operates on a separate circuit).
In most cases, the problem is solved by replacing the faulty part. If the refrigerator has one compressor, then the cause may be malfunction of the thermostat or clogged capillary tubes.
