Refrigerators Gorenje are popular household appliances that combine European quality and affordable prices. But how exactly do they maintain a low temperature inside the chamber, even when it’s +30°C outside? Let's understand the principles of operation, key components and typical “weak points” of this brand’s equipment.
The basis of the functioning of any refrigerator is heat transfer from the inside to the outside. Two main technologies are used for this: Gorenje For this, two main technologies are used: compressor (in 90% of models) and absorption (in rare copies, for example, in camping or gas refrigerators). We will analyze both systems in detail, paying attention to their pros, cons and maintenance features.
It is important to understand: even if your refrigerator Gorenje suddenly stopped freezing, the problem most often lies in one of three components - the compressor, thermostat or refrigerant circulation system. Knowledge of the device will help you more accurately diagnose a malfunction and save on calling a technician.
Compressor refrigerators Gorenje: how it works
Most models Gorenje (for example, series NRK6191 or RK4181) are equipped compressor cooling cycle. Its operation is based on the physical properties of a refrigerant - a special gas (most often R600a or R134a), which boils at low temperatures.
The process can be divided into 4 stages:
- Evaporation: The refrigerant in a liquid state enters Evaporator (located inside the fridge compartment). Here it boils, absorbing heat from the air and cooling the chamber.
- Compression: The compressor “sucks” the gaseous refrigerant and compresses it, increasing the temperature and pressure.
- Condensation: Hot gas passes through condenser (the grill on the back wall of the refrigerator), gives off heat to the environment and becomes liquid again.
- Throttling: Liquid refrigerant passes through capillary tubewhere its pressure drops sharply - the cycle repeats.
The key element of the system is thermostat (or an electronic control unit in modern models). It monitors the temperature in the chamber and turns the compressor on/off. For example, refrigerators Gorenje NKI6191 use an electronic controller with sensors, which makes the work more accurate than a mechanical thermostat.
Absorption refrigerators Gorenje: features and scope of application
Absorption models (for example, Gorenje RC4111 or camping refrigerators series GC) work without a compressor. Instead, it is used absorption cyclewhere the refrigerant (usually ammonia) is dissolved in water and then released back when heated.
Advantages of such a system:
- 🔹 Noise: no moving parts (except for the fan in some models).
- 🔹 Reliability: fewer elements that can break.
- 🔹 Work from different sources heat: electricity, gas or even solar panels (in camping versions).
However, there are also disadvantages:
- ⚠️ Low efficiency: they consume more energy for the same level of cooling.
- ⚠️ Long start-up: after switching on, they can cool to the desired temperature in 6–12 hours (versus 1–2 hours for compressor).
- ⚠️ Sensitivity to tilt: during transportation they require a strictly vertical position (otherwise the fluid circulation is disrupted).
Absorption refrigerators Gorenje more often found in:
- 🏕️ Camping and tourist models (for example, Gorenje GC100).
- 🏠 Houses without a centralized power supply (gas versions).
- 🚐 Motorhomes and yachtswhere it is important noiselessness.
The main components of the refrigerator Gorenje and their functions
To understand why the refrigerator does not freeze or makes strange sounds, you need to know its “anatomy”. The table below shows the key components and their role in the system.
| Knot | Function | Typical malfunctions |
|---|---|---|
| Compressor | Compresses the refrigerant and ensures its circulation | Does not turn on, works without stops, knocking |
| Condenser | Removes heat from the refrigerant (grid at the back) | Dust contamination, mechanical damage |
| Evaporator | Absorbs heat from the chamber (hidden behind the rear panel) | Freezing, refrigerant leak |
| Thermostat/electronic unit | Controls temperature and controls the compressor | Incorrect readings, refusal to turn on cooling |
| Capillary tube | Reduces the refrigerant pressure in front of the evaporator | Clogging, obstruction |
In models with a system No Frost (for example, Gorenje NKI6191) is added fan for forced air circulation and heater. defrostingwhich is periodically turned on to remove frost. This complicates the design, but eliminates the need to defrost the refrigerator manually.
What is a “crying” evaporator?
In refrigerators without No Frost (for example, Gorenje RK4181) the evaporator is located on the back wall of the chamber during operation, frost forms on it, which melts and flows into a special tray when the compressor is turned off - hence the name. "crying."
Typical malfunctions and their causes
Refrigerators Gorenje, like any equipment, fail over time. Let's look at the most common problems and their possible causes.
1. lights up
- 🔧 Compressor burnt out (no characteristic hum).
- 🔧 Refrigerant leak (crack in pipes or evaporator).
- 🔧 Thermostat is faulty (does not give a signal to switching on).
- 🔧 Capillary tube is clogged (refrigerant does not circulate).
2. The refrigerator runs without stopping
- ❄️ The door is not closed tightly (check seal).
- ❄️ High temperature in the room (the condenser cannot cope).
- ❄️ Faulty thermostat (sticks in the "on" position).
- ❄️ Refrigerant leak (the compressor tries to compensate for the lack of cold).
3. The light constantly flickers or the indicator blinks
- ⚡ Problems with electronics (control unit, sensors).
- ⚡ Power surges (stabilizer needed).
- ⚡ Faulty defrost heating element (in models with No Frost).
4. Strong noise or vibration
- 🔊 The compressor fastenings are loose (you need to tighten the bolts).
- 🔊 A foreign object has entered the fan (in models with No Frost).
- 🔊 Wear of motor bearings (requires replacement).
5. Ice or a snow “coat” forms on the back wall
- ❄️ Clogged drainage hole (the water does not drain, it freezes).
- ❄️ Faulty defrost heating element (in No Frost).
- ❄️ Refrigerant leak (evaporator freezes).
☑️ Diagnosis of refrigerator malfunctions Gorenje
How to extend life refrigerator Gorenje: operating tips
The service life of the refrigerator depends not only on the build quality, but also on the conditions of use. By following simple rules, you can avoid many breakdowns:
1. Correct installation
- 📏 Distance from the wall: at least 5 cm for ventilation of the condenser.
- ⚡ Socket: must be grounded, without adapters.
- ☀️ Avoid direct sunlight and heat sources (stoves, batteries).
2. Care for the seal
- 🧼 Clean the rubber soap solution 1-2 times a month.
- 🔍 Check the tightness of the seal: a sheet of paper should not fall out when the door is closed.
- 🚫 Do not slam the door —this will deform the seal.
3. Defrosting and cleaning
- ❄️ Models without No Frost defrost 1-2 times a year.
- 🧊 Do not use sharp objects to remove ice.
- 🧽 Wash the internal surfaces soda solution (1 tbsp. spoon per 1 liter of water).
4. Loading products
- 🥦 Do not place hot dishes - this increases the load on the compressor.
- 📦 Distribute food evenly for good air circulation.
- 🚫 Do not overload the door - this disrupts tightness.
When to call a technician: signs of serious damage
Some malfunctions can be eliminated yourself (for example, replacing the seal or cleaning the condenser). However, there are symptoms for which it is strictly not recommended to carry out repairs without a specialist: If you suspect a refrigerant leak (for example, the compressor is running but not cooling), do not try to charge the system yourself. It is strictly not recommended to carry out repairs without a specialist:
⚠️ Attention: If you suspect a refrigerant leak (for example, the compressor is running but not cooling), do not attempt to charge the system yourself.R600aandR134a— explosive gases, and special equipment is required for refueling.
Signs requiring professional repair:

FAQ: Frequently asked questions about refrigerators Gorenje
Why does a refrigerator Gorenje hum loudly when operating?
The hum can be caused by several reasons:
- 🔹 Uneven installation - check if the refrigerator is shaking, adjust the legs.
- 🔹 Touching of the compressor tubes to the housing - carefully bend them.
- 🔹 Wear of motor bearings - requires replacement compressor.
- 🔹 High load (for example, heat in the room or an open door).
If the hum appears suddenly and is accompanied by vibration, call a technician for diagnostics.
Is it possible to transport a refrigerator Gorenje lying down?
Compressor models you can transport lying downbut subject to the rules:
- 🔹 Place the refrigerator on its side (not on the door or the back wall).
- 🔹 Secure the compressor with shipping bolts (if included).
- 🔹 After transportation do not turn on refrigerator for 2–4 hours (so that the oil flows into the compressor).
Absorption models cannot be transported lying down - this will disrupt the circulation of liquid in the system.
What to do if the refrigerator Gorenje does not turn off?
If the compressor runs without stopping, follow these steps:
- Check is the door tightly closed and whether the seal is damaged.
- Make sure that the thermostat is not set to maximum (turn the knob to the middle position).
- Clean condenser from dust (grid on the back wall).
- Check if the refrigerator near the heat source (battery, stove).
If the problem persists, most likely it is faulty thermostat or leak refrigerant - contact service.
What refrigerant is used in refrigerators Gorenje?
Most modern models Gorenje are used:
- 🔹
R600a(isobutane) - an environmentally friendly but flammable gas. Used in models after 2010. - 🔹
R134a- less effective, but safe. Found in old refrigerators.
Absorption models operate on ammonia (NH₃), which circulates in a closed circuit with water.
