Owners of household appliances often wonder which compressor is installed in their Beko refrigerator, especially when there is a need to replace or diagnose a fault. The company Beko is one of the largest manufacturers of household appliances in Europe, and in its refrigeration units it uses various types of motor-compressors, which depends on the specific series, year of manufacture and price segment of the model. Understanding exactly which mechanism ensures the circulation of the refrigerant is critical for proper maintenance.
In the modern lines of refrigeration equipment the Turkish brand you can find both classic piston units and advanced inverter systems. The choice of a specific motor type directly affects energy consumption, noise level during operation and durability of the entire device. If you are planning independent repairs or simply want to understand the structure of your device, you need to know the technical features of the unit installed in it.
You can determine the type of compressor in several ways: by the sound of the operating unit, by the markings on the motor housing itself, or by studying the technical data sheet of the device. In this article we will analyze in detail what types of engines it uses, what is their difference and what to look for when choosing spare parts. This will help you avoid mistakes when ordering spare parts and better understand the operating principle of your equipment. Beko, what is their difference and what to look for when choosing spare parts. This will help you avoid mistakes when ordering spare parts and better understand how your equipment operates.
Main types of compressors in Beko equipment
In refrigerators Beko two main types of compressors are mainly used: standard piston and inverter. Standard models operate on the “on-off” principle, that is, the motor starts at full power, cools the chamber to the set temperature and turns off. This cycle is repeated constantly, which creates characteristic clicks when starting and stopping. Piston compressors time-tested and distinguished by their maintainability, although they are inferior in energy efficiency.
Inverter compressors are a more complex design, where the engine rotation speed is adjusted smoothly depending on the current load. Instead of shutting down completely, the motor Inverter simply reduces the speed, maintaining the temperature within a narrow range. This allows you to significantly reduce noise levels and energy consumption. In the lines No Frost from Beko, such systems are increasingly found, providing a stable microclimate.
It is also worth mentioning linear compressors, which, although less common, can be found in the brand’s top models. They operate without a crank mechanism, which theoretically reduces the number of rubbing parts. However, in the mass segment Beko more often it relies on high-quality piston and inverter solutions from trusted suppliers. The choice of engine type depends on the tasks that the manufacturer sets for itself in a specific price niche.
⚠️ Attention: When ordering spare parts, always check not only the type of compressor, but also its geometric dimensions, the location of the pipes and the type of refrigerant. Installing an unsuitable motor can lead to damage to the cooling system.
The differences between motor types lie not only in the principle of operation, but also in the electrical requirements. Inverter models are sensitive to voltage surges, so for their stable operation it is recommended to use surge protectors or stabilizers. Conventional piston engines are more “omnivorous”, but create a greater load on the network at the time of startup. Understanding these nuances will help extend the life of your refrigerator.
Technical characteristics and markings
To accurately determine which compressor is in your refrigerator Beko, you need to refer to the technical information. It is usually located on a sticker inside the chamber or on the back wall of the unit. The serial number of the model is indicated there, which allows you to find the exact specification on the official website. However, this is not enough to select a spare part - you need to see the markings on the motor itself.
A label with key parameters is stamped or pasted on the compressor housing. Among them, the most important are the manufacturer (for example Secop, Embraco, Aspera or itself Beko), the type of refrigerant (R600a or R134a) and the refrigeration capacity. Cooling capacity is measured in BTU or kcal/h and indicates the power of the unit. Incorrect selection of power will lead to the fact that the refrigerator will not maintain the temperature or will work without stopping.
Also pay attention to the electrical characteristics: supply voltage (220-240V), frequency (50/60 Hz) and starting current. For inverter models, matching the control type and communication protocol with the refrigerator control board is critical. Electronics Modern models are often “tied” to a specific type of motor, and a simple one-to-one replacement in size may not work without flashing.
| Parameter | Piston compressor | Inverter compressor | Linear compressor |
|---|---|---|---|
| Operating principle | Cyclic (On/Off) | Smooth speed control | Reciprocating |
| Noise level | Medium/High | Low | Very low |
| Energy consumption | Standard | Economical (Class A+ and higher) | Maximum economical |
| Sensitivity | Low | High to voltage surges | High |
The marking also contains information about the type of oil used in the system. Synthetic and mineral oils should not be mixed. If there was R600a refrigerant (isobutane) in the system, then the new compressor should be designed specifically for it. Ignoring this rule can lead to an explosive situation or rapid failure of the new unit due to lack of lubrication.
How to determine the type of motor installed
There are several practical ways to understand which compressor is running in your refrigerator Beko, without having to disassemble the back wall. The simplest method is acoustic. Listen to the operation of the unit in silence. If you hear a distinct start click, then a buzz, and after a while a stop click and silence, it means you have a classic piston compressor installed. In the case of an inverter model, the picture is different. After the initial start-up, the refrigerator does not shut down completely. It emits a very quiet, barely perceptible hum, which can change its tone (either quieter or louder), but does not stop completely. This is the normal mode of operation piston compressor.
In the case of the inverter model, the picture is different. After the initial start-up, the refrigerator does not shut down completely. It emits a very quiet, barely perceptible hum, which can change its tone (either quieter or louder), but does not stop completely. This is normal operation Inverter of the system, which maintains the temperature while operating at low speeds. The absence of loud clicks is the main sign of an inverter.
Visual inspection through the ventilation grille at the back can also give clues. Inverter compressors often have a more compact, “flattened” body and a characteristic “barrel” or cylinder shape with an electronic control unit mounted directly on the motor housing. Conventional compressors, as a rule, look like black metal “cans” with a separate start relay and capacitor (although in modern models the relay can be integrated).
- Listen to the refrigerator in silence: are there any pauses in operation?
- Inspect the back wall: is there an electronic board on the motor?
- Check the sticker inside the refrigerator compartment for the presence of the word Inverter.
- Evaluate the smoothness of the temperature rise (inverters do not give sudden jumps).
Why is the inverter humming?
The hum of the inverter compressor may intensify during active freezing or if you have just loaded with a lot of warm food. This is the normal high power mode.
If visual and acoustic methods do not provide an accurate answer, refer to the documentation. The operating instructions always indicate the type of compressor in the “Technical Specifications” section. Also, the compressor model is often duplicated on the service sticker, which can be located behind the baseboard of the refrigerator or on the base. The full part code will be indicated there, which can be checked in the spare parts database.
Popular manufacturers and compatibility
The company Beko does not produce compressors independently for all its needs, but purchases them from the world's leading specialized factories. Most often in refrigerators of this brand you can find engines of the brands Secop (formerly Danfoss), Embraco, Aspera (now part of Embraco/Nidec) and LG (for inverter models). Understanding who the real manufacturer is helps in finding analogues.
Compressors Secop are considered one of the most reliable and widespread in the European assembly. They are distinguished by high maintainability and the presence of a large number of analogues. If your Beko has just such a motor, finding a replacement or spare parts for it will not be difficult. They are known for their “survivability” even under non-ideal operating conditions.
Inverter systems are often supplied by the company LG or own developments under the brand Beko, made on the basis of technologies Embraco. Compatibility is more complicated here: an original inverter compressor often requires an original control board. An attempt to install an analogue from another manufacturer may require complex reconfiguration of electronics, which is almost impossible to do at home.
- 🔧 Secop/Danfoss: Classic reliability, easy to find a replacement.
- ⚡ Embraco/Aspera: High efficiency, often found in No Frost.
- ❄️ LG Inverter: Quiet operation, but demanding on the network and electronics.
- 🏭 Beko Original: They may be rebrandings of other factories, search by code.
When ordering spare parts through online stores or service centers, always indicate the exact model refrigerator Beko. Spare parts specialists have access to cross-databases, which indicate which factory compressor was installed on your specific batch of equipment. This will eliminate the need to guess and buy the wrong part.
Causes of failure and diagnostics
Compressors in refrigerators Beko, like any other equipment, are subject to wear. The most common cause of breakdown is the interturn short circuit electric motor windings. This can occur due to a power surge, aging insulation, or prolonged operation under extreme conditions (for example, overheating). In this case, the motor either hums, but does not start, or knocks out the machine in the shield.
The second common problem is mechanical wear of the piston group or jamming of the shaft. This often happens if the refrigerator has been turned off for a long time and the oil has thickened, or if the tightness of the system has been broken and air with moisture has gotten inside. The symptom is a loud knock, a clanging sound when starting up, or a complete lack of vibration of the housing when the electric current is running. Jagging often requires replacing the entire assembly.
The third reason is problems with the starting relay. Although it is not the compressor itself, a faulty relay prevents a working motor from starting. In refrigerators Beko relays are often integrated into the body, but in older models they are removable. If you hear a click when you turn it on, the hum lasts 3-5 seconds, then click again and silence - most likely the problem is in the relay or that the compressor cannot turn over (jammed).
⚠️ Attention: Compressor diagnostics require working with high voltage 220V and potentially dangerous gas under pressure. If you do not have the skills to work with electrical appliances and refrigerants, entrust the diagnostics to professionals.
For accurate diagnostics, technicians use a multimeter (to test the windings) and a pressure gauge station (to check the discharge pressure). The resistance of the windings must be in a certain range (usually from 10 to 30 Ohms for the starting and operating windings in total). If the resistance tends to zero (short circuit) or to infinity (break), the compressor is faulty and requires replacement.

Replacing a compressor: main steps
Replacing a compressor in a refrigerator Beko is a complex technical process that cannot be performed without special equipment. You will need: a torch (gas or oxy-acetylene), a vacuum pump, a pressure gauge station, a scale for charging refrigerant and tools for rolling pipes. Simply “unscrewing and screwing” will not work here, since the system is sealed and filled with gas.
The first step is always pumping out the old refrigerant and dismantling the faulty motor. The tubes are cut or soldered off, the old compressor is removed from the frame. Then the new unit is installed in place. It is critically important to select a compressor with a similar diameter of fittings (tubes) in order to avoid unnecessary rolling and narrowing of the line, which will worsen circulation.
After installing a new motor and filter-drier (it is always changed!) the system is sealed. Then a vacuum must be carried out for 15-30 minutes to remove moisture and air. Only after creating a vacuum, the system is charged with a strictly defined amount of refrigerant (the weight is indicated on the sticker inside the refrigerator). Overcharging or undercharging will lead to incorrect operation or breakdown.
- Draining the refrigerant and dismantling the old compressor.
- Installing a new motor and filter drier.
- Soldering connections and checking tightness with nitrogen.
- Evacuation of the system.
- Filling with an exact dose of refrigerant and test run.
Why change filter drier?
The filter drier absorbs moisture from the system. When the circuit is opened, it is saturated with moisture from the air within minutes. If it is not replaced, the moisture will freeze in the capillary and block the operation of the refrigerator.
After completion of the work, the refrigerator should operate for several hours in test mode. The master checks the evaporator temperature, compressor current consumption and condenser temperature. If all parameters are normal, the refrigerator Beko is ready for use. Remember that the warranty for a replaced compressor is valid only if there is a receipt and a certificate of work performed from a certified technician.
Frequently asked questions (FAQ)
Is it possible to replace a regular compressor in Beko with an inverter one?
Theoretically it is possible, but technically and economically inappropriate. You will have to change the control board, reprogram the refrigerator electronics, and possibly change the wiring. It is easier and cheaper to buy a new refrigerator with an inverter than to upgrade an old one.
Why does the new compressor in a Beko refrigerator heat up to 80-90 degrees?
This is normal for many types of compressors, especially during intensive operation or in a hot room. The housing can heat up to 90°C. You should be concerned if the temperature is higher or if only one local point is heated (for example, the exit point of the tube), which may indicate a blockage.
How long does the compressor in a Beko refrigerator last on average?
The average service life of a high-quality compressor is 10-15 years. Inverter models with a stable network voltage can operate for up to 20 years or more. Piston models are also durable, but their service life depends on the number of on/off cycles.
Is a Beko compressor humming - is this normal?
A slight hum or vibration is a normal operating sound. However, if the humming becomes a knocking, clanging, or loud ringing sound, it is a sign of mechanical failure. You should also sound the alarm if the sound has become significantly louder than before.
