What compressors are installed on Indesit refrigerators: review of models and manufacturers

Owners of household appliances are often faced with the need for repairs when the refrigerator stops cooling or starts making strange sounds. At the heart of each unit is compressor, which is responsible for the circulation of the refrigerant. It is this unit that most often fails or requires replacement when moving. For owners of Italian equipment assembled in Russia, the question of which engines are used in their models becomes critically important when planning the budget for repairs.

In refrigerators Indesit over the years, various types of motor-compressors have been used, which depends on the year of manufacture and series of the device. Understanding exactly which unit is installed in your model will help you avoid mistakes when ordering spare parts. The bulk of modern Indesit refrigerators are equipped with closed-type piston compressors designed to work with refrigerant R600a. This is important to consider, since replacing it with an analogue with a different type of freon will require a complete overhaul of the system.

You should not ignore the first signs of a malfunction, since failure of the piston group can lead to a complete loss of products. In this article we will take a detailed look at which manufacturers supply components to Indesit factories, what is the difference between conventional and inverter models, and how to choose the right replacement. You will find out why the old unit is humming and whether it is worth replacing one compressor with two.

Main types of compressors made by Indesit technology

Brand equipment Indesit, like many other European brands, does not produce compressors independently. Assembly plants purchase finished components from specialized manufacturers. Depending on the price segment and year of production, several main types of engines can be found in refrigerators. The most common option is piston compressorwhich operates on the principle of reciprocating movement of the piston.

Such motors are highly reliable and maintainable, although they create a certain level of noise during operation. In more modern and expensive models, especially in lines with the NoFrostsystem, inverter compressors can be installed. They regulate the shaft rotation speed, which saves energy and maintains a more stable temperature in the chambers.

It is also worth noting the difference in the refrigerant used. Older models could operate on R134a freon, but environmental standards and energy efficiency requirements switched production to isobutane (R600a). Compressors for R600a have lower productivity and volume, and also differ in the design of the suction and discharge tubes.

⚠️ Attention: An attempt to fill a compressor designed for R600a with R134a freon, or vice versa, will lead to instant failure of the motor and possible fire. Always check the label on the back wall of the refrigerator.

You can determine the type of unit you have installed by the labeling. It is usually applied to a black metal casing located at the bottom rear of the device. If you are planning a replacement, you need to check not only the manufacturer, but also engine power, the type of start (RSIR or RSCR) and the geometric dimensions of the seats.

How to read the compressor markings?

The marking usually contains the manufacturer's code (for example, SECOP, DANFOSS), refrigerant type (R600a), voltage (220-240V) and frequency (50Hz). The power in BTU or HP (horsepower) is also indicated.

Manufacturers of components for Indesit refrigerators

Analyzing the spare parts market and the internal structure of Indesit refrigerators, we can identify several key suppliers of compressors. The brand is not tied to one plant, so identical-looking models can have completely different engines. This depends on the logistics chains of the assembly plant at the time the batch is produced.

One ​​of the most common suppliers is the company Secop (formerly known as Danfoss). The German quality of these compressors has proven itself over decades of operation. They are characterized by low noise levels and high fault tolerance. You can find such motors both in old models and in relatively new series.

Another major player is the Italian company Embraco (now part of Nidec Global Appliance). Compressors of this brand can often be found in equipment in the middle and high price segments. They are known for their compactness and efficiency. Also on the market there are units from LG and Whirlpoolthat were supplied to Indesit factories under contracts.

• 🔧 Secop (Danfoss): are considered the standard of reliability, often have a metal body and low vibration levels.
• ❄️ Embraco: are characterized by high performance and are often used in systems NoFrost.
• ⚙️ ACC (Aspera): another Italian brand, part of the Embraco concern, is widely distributed in budget lines.
• 🇰🇷 LG / Samsung: Korean engines are less common, mainly in models produced in recent periods.

When purchasing spare parts for replacement, technicians often focus on the availability of analogues. If the original compressor Danfoss is difficult or expensive to find, it is often replaced with a proven analogue from Embraco with similar power characteristics. The main thing is that the parameters of the starting torque and the type of refrigerant match.

Correspondence table of models and characteristics

To simplify the search for information about which compressors are installed for Indesit refrigerators, we have compiled a summary table. It will help you navigate the main parameters that need to be taken into account when selecting a replacement. Remember that even within the same series of refrigerators, the manufacturer can change the supplier of components.

Below is the data for the most common types of motors found in equipment assembled in Russia and Europe. Pay attention to the power and type of freon, as these are key parameters of compatibility.

Using a compressor with more power than the design provides can lead to freezing of products and overload of the condenser. Conversely, a weak motor will not be able to provide the required temperature in the freezer, especially in super-freezing mode. Exact match model or its high-quality analogue is the key to a long service life of the refrigerator after repair.

Causes of failure and symptoms of failure

A compressor is a complex mechanical unit that operates under high pressure. Its service life is usually 10-15 years, but external factors can significantly shorten this period. Understanding the causes of the breakdown will help prevent the situation from reoccurring after replacement.

One ​​of the most common reasons is overheating. If the refrigerator is close to the wall, or the condenser (grid at the back) is clogged with dust and animal hair, the motor is overloaded. The thermal relay tries to protect the windings by turning off the unit, but over time the insulation of the wires is destroyed and a short circuit occurs.

Another common problem is a violation of the tightness of the system. If a microcrack appears in the circuit, the refrigerant leaves, and along with it the oil. Operating the compressor without oil or on a mixture of oil and air leads to jamming of the piston group in a matter of minutes. In this case, the engine hums, but does not start, or starts for a couple of seconds and stalls.

• 🔊 Loud knocking and clanging: indicates the destruction of internal valves or bearings.
• 🔥 Housing heating: if the compressor is hot to the touch (more than 80-90 degrees), this is a sign of a malfunction.
• 🔌 Knocking out plugs: short circuit in the motor windings.
• 🧊 Lack of cold: When the engine is running, indicates a freon leak or capillary blockage.

Sometimes users confuse a compressor breakdown with a faulty start relay. This is a small part that fits onto the contact group of the motor. If the relay sticks or burns out, the compressor does not receive an impulse to start, although electricity is supplied to it. Replacing the relay is inexpensive and often solves the problem of a “humming” refrigerator.

⚠️ Attention: If after replacing the compressor the system has not been properly vacuumed, the remaining moisture will turn into an ice plug or acid, which will kill the new motor within a few months.

Features of replacing the compressor at home

Replacing a compressor in an Indesit refrigerator is a technically complex procedure that requires specialized equipment. Unlike replacing a light bulb or a gasket, you can't get by with a set of screwdrivers. The process involves working with gas under pressure and soldering copper tubes.

The first stage is always evacuation systems. After installing the new motor and filter drier, all air and moisture must be removed from the circuit. For this, a vacuum pump is used, which is connected to the service pipe. The evacuation time is at least 15-20 minutes so that the pressure drops to a deep vacuum.

Next is charging with refrigerant. The amount of freon must be strictly dosed in grams, according to the data on the refrigerator nameplate. Overfilling or underfilling will lead to incorrect operation. For R600a (isobutane) this is especially critical, since the gas is explosive when concentrated in air.

After refueling, it is necessary to check the tightness of all connections. The technician uses a soap solution or a leak detector to make sure that the gas is not poisoning. Only after a successful test is the refrigerator connected to the network, and the operating cycle is checked: temperature set, shutdown by thermostat, no excessive heating of the case.

Inverter compressors: the future or marketing?

Inverter compressors can increasingly be found in modern models of Indesit refrigerators. Unlike traditional ones, which work on the principle of “turned on - cooled - turned off”, inverter motors do not stop completely. They smoothly regulate their power, maintaining the set temperature.

The main advantage of this technology is energy efficiency low noise level. The absence of constant starting currents extends the service life of mechanical parts. In addition, the temperature in the chambers becomes more stable, which has a beneficial effect on the safety of products.

However, there are also disadvantages. Inverter compressors are sensitive to voltage fluctuations in the network. To protect them, the installation of a stabilizer is often required. In addition, the cost of such components is much higher, and fault diagnosis requires more complex equipment, since control is carried out via an electronic board.

If your Indesit refrigerator has an inverter motor and it fails, replacing it with a regular (non-inverter) compressor will require changing the electrical circuit. You will have to install a start relay and possibly change the thermostat. Therefore, when an inverter breaks down, it is most often recommended to look for an original replacement or a certified analogue with a similar operating principle.

FAQ: Frequently Asked Questions

Is it possible to replace an R134a compressor with an R600a in an Indesit refrigerator?

Theoretically, this is possible, but requires complete resoldering the system and replacing the capacitor, since different freons have different operating pressures and properties. A simple one-to-one replacement will not work due to differences in the design of the pipes and the required oil. This is not economically feasible.

Why is the new compressor louder than the old one?

Modern compressors can operate louder due to higher speeds and lighter housing weight, which dampens vibrations less well. Also, the reason may be incorrect installation (tubes touching the body of the refrigerator) or the absence of vibration-damping rubber bands on the legs.

How much does it cost to replace a compressor in Indesit?

The cost consists of the price of the unit itself (from 4,000 to 12,000 rubles depending on the model) and the work of the technician (from 3000 to 6000 rubles). The total amount is often more than 7-10 thousand rubles, which must be taken into account when repairing old refrigerators.

Warranty period for the installed compressor?

Usually service centers give a guarantee of 6 to 12 months for work and installed spare parts. However, the warranty does not cover cases of power surges, mechanical damage or repeated leakage of freon due to corrosion of the tubes.

Is it worth repairing an Indesit that is older than 10 years?

If a compressor replacement is required, the repair is often comparable in price to 30-40% of the cost of a new refrigerator. If the remaining components (evaporator, housing, seals) are in good condition, repair makes sense. Otherwise, it’s easier to consider buying new equipment with a guarantee.
