Brand refrigerators Indesit have held a strong position in the household appliances market for decades, famous for their simplicity and maintainability. However, like any complex mechanism, they are subject to wear, and the most common cause of failure is compressor. It is this unit that is responsible for circulating the refrigerant in the system, creating the necessary pressure to cool the chambers.
Owners are often faced with a dilemma: what kind of engine was originally installed in their model and what can replace it with so as not to disrupt the operation of the electronics or start relay. Knowledge of the specifics compressorsused by the Italian brand allows you not only to correctly diagnose a breakdown, but also to save significant money when ordering spare parts, avoiding overpayments for universal, but not always suitable analogues.
In this article we will analyze in detail the evolution of engines in refrigerators Indesit, we will look at the differences between linear and inverter models, and also provide a compatibility table for popular series. Understanding these nuances is critically important for craftsmen and those planning independent repair household appliances.
The evolution of engines in Indesit refrigeration equipment
The history of refrigerator production Indesit has many stages, and at different times the company used different refrigerant compression technologies. At the dawn of mass production, reciprocating piston compressors were the most common. They were highly reliable, but had a significant drawback - high levels of noise and vibration during operation.
Over time, trying to increase energy efficiency and reduce sound pressure, brand engineers began to introduce more advanced models. In modern lines, they are increasingly found linear compressorsthat do not have a crank mechanism, which makes their operation much quieter. It is also worth noting the appearance of inverter systems in premium series, although the mass market Indesit remained faithful to classic solutions for a long time.
⚠️ Attention: If you try to replace an old piston compressor with a more modern linear or inverter without appropriate modification of the electronic control board, the refrigerator may not start or may fail building in a short time.
It is important to understand that the transition to new types of engines often required changing the design of the refrigeration unit itself. Therefore, if you are looking for a replacement for a model released 10–15 years ago, most likely, we will be talking about a classic piston unit, which has structurally changed little since its creation.
Main manufacturers and markings of compressors
The company Indesit (part of the Whirlpool group) does not produce compressors independently, but purchases them from specialized partner factories. Over the years, the main suppliers have been such industry giants as Aspera (previously known as Embraco Europe), Danfoss (now Secop), LG and Chinese Jiaxipera. The marking on the device nameplate contains all the necessary information for selecting an analogue.
The key parameter when choosing is the refrigerant the engine is designed to work with. In older models, freon was used, which was replaced with a more environmentally friendly one (isobutane). reworking the system, since they use different types of oils and have different operating pressures. Indesit freon was used R134a, which was replaced with a more environmentally friendly one R600a (isobutane). Compressors for different types of gas non-interchangeable without deep reworking of the system, since they use different types of oils and have different operating pressures.
When deciphering the model code, pay attention to the letters at the end of the name. For example, in the marking Aspera the letter "T" often indicates the type of refrigerant, and the numbers indicate cylinder volume and power. An error in identification can lead to the new motor working with overload or not providing the required temperature.
Aspera and Embraco line: a classic for Indesit
Perhaps the most common engines that can be found in refrigerators Indesit made in Europe are units produced by Aspera. These compressors have proven themselves to be “workhorses” that can operate for years under voltage surges. They belong to the class of sealed piston mechanisms.
One of the popular series is the model range Aspera NJ i Aspera NBseries. The former are usually designed for refrigerant R134a, and the latter - for R600a. Their design involves the presence of an external start relay, which often fails before the compressor itself. When diagnosing a malfunction, this element should be checked first.
A distinctive feature of these engines is their maintainability and availability of spare parts. However, it is worth considering that they are quite sensitive to the cleanliness of the circuit. When replacing such a compressor, the procedure of purging the system and installing a new filter-drier is mandatory.
Marking secrets. Aspera
In a model code, for example T 60 HL, the first digit (60) indicates the volume of the cylinder in cubic centimeters, and the letters HL indicate low torque (Low Torque), which is typical for household refrigerators.
If you see the logo Embracoon your unit, know: this is the same plant as Aspera, just branded in the old way or for certain sales markets, their technical characteristics and overall dimensions are usually identical, which simplifies the search for a replacement.
Danfoss (Secop) compressors and their features
Danish. The company Danfoss (whose compressor business was sold and renamed to Secop) also supplied a significant number of engines for refrigerators Indesit, especially for models assembled at factories in Russia and the CIS countries. These compressors are known for their high energy efficiency and compact size.
Series BD i TL from Danfoss was often found in two-chamber refrigerators of medium volume. Their design feature is the use of special oils compatible with a specific type of freon. Mixing oils of different types is strictly prohibited, as this can lead to the formation of an acidic environment inside. systems and breakdown of windings.
Unlike noisier analogs, compressors Danfoss are often quieter, which is an important advantage for kitchens combined with a living room. However, their cost on the aftermarket may be slightly higher than that of their Chinese counterparts.
| Parameter | Aspera (Embraco) | Danfoss (Secop) | Jiaxipera |
|---|---|---|---|
| Brand country | Italy / Brazil | Denmark / Germany | China |
| Refrigerant type | R134a, R600a | R134a, R600a | R134a, R600a |
| Level noise | Average | Low | Medium/High |
| Reliability | High | Very high | Average |
When choosing between the original Danfoss and its analogue, it is important to pay attention to the mounting dimensions of the mounting tabs. Sometimes, even if the power is the same, the geometry of the case may differ by several millimeters, which will require modification of the base.
Chinese analogues: Jiaxipera and. other brands
In recent years, the spare parts market has been flooded with Chinese-made compressors, among which the company is leading. JiaxiperaThese engines are often installed on new refrigerators Indesit in order to reduce the cost of the final product. The issue of their reliability still causes controversy among craftsmen.
On the one hand, modern Chinese compressors have learned to meet international quality standards and have the necessary certificates. On the other hand, their service life may be inferior to their European counterparts, and the build quality sometimes suffers from batch to batch. However, for budget repairs they remain the only option.
⚠️ Attention: When purchasing a Chinese compressor, be sure to check the presence of oil in the transport plug. If, when opening the package, the oil leaked out or there was too little oil, it is better not to use such a unit.
Models Jiaxipera series H and Q are direct competitors Aspera. They often have similar electrical characteristics, which allows you to use standard starting relays from old engines, although the manufacturer always recommends changing the relay complete with a new motor.
Inverter compressors in modern ones models
With the development of energy saving technologies, inverter compressors began to appear in top models Indesit . Unlike classic ones, they do not turn off completely, but smoothly regulate the shaft rotation speed, maintaining the set temperature. This allows you to achieve energy consumption class A++ and higher.
The main supplier of such solutions is often the company LG or the holding's own developments Whirlpool. Such motors operate virtually silently and have an extended service life due to the absence of constant start and stop cycles, which wear out the mechanism the most.
However, repairing or replacing an inverter compressor is a complex and expensive process. Here it is not enough to simply change the “motor”; often the control board needs to be replaced, which costs a significant part of the price of the refrigerator itself.
☑️ Signs of an inverter malfunction
If your refrigerator with an inverter compressor has stopped cooling, do not rush to buy a new motor. In 70% of cases, the problem lies in the electronics or temperature sensors, but the inverter unit remains serviceable.
Correspondence table and popular replacements
For ease of selection of spare parts, we have compiled a summary table of correspondence of popular compressor models, installed on refrigerators Indesit. Remember that the final decision on replacement must be made by a specialist based on the technical parameters of a particular device.
| Original (Indesit) | Aspera analogue | Danfoss analogue | Jiaxipera analogue |
|---|---|---|---|
| CBI 4000 | NB 92 L | BD 35 G | H 80 G |
| CBI 5000 | NB 100 L | BD 50 G | H 90 G |
| R 134a Old | T 60 HL | TL 45 G | QD 35 G |
| R 600a New | NB 92 L | BD 35 G | H 80 G |
Using the table allows you to quickly navigate the assortment of spare parts stores, where original codes may not be available, but their direct analogues are present. The main thing is the match of power and type of refrigerant.
How to choose the right replacement and avoid mistakes
The process of selecting a new compressor begins not with a trip to the store, but with a careful study nameplate on the old unit. You should be interested in: the type of refrigerant, cylinder volume (cm³), power (W or 1/5, 1/4 hp) and type of starting device (RSIR, RSCR, CSIR).
A common mistake is to try to install a more powerful compressor “with a reserve”. This can lead to the evaporator and condenser not being able to remove heat effectively, and the thermostat not working correctly, causing frequent switching on and off.
It is also important to consider the overall dimensions. Compressors of different series may have different heights or locations of pipes. Before purchasing, it is recommended to measure the distance from the base to the top point and the distance between the mounting legs.
⚠️ Attention: Never solder pipelines with the compressor installed without first pumping out the freon and purging the system with nitrogen. Remaining moisture will lead to rapid failure of the new engine.
If you are not confident in your abilities, it is better to entrust the replacement to professionals. Incorrect refilling with freon or breaking the vacuum in the system will negate all efforts to replace an expensive unit.
Why you can’t save on a filter drier
When replacing a compressor, air and moisture inevitably enter the system. A cheap or old filter will not be able to adsorb all the moisture, which will lead to the formation of an ice plug or acid that corrodes the windings from the inside.
Frequently asked questions (FAQ)
Is it possible to replace an R134a compressor with an R600a?
No, this is impossible without complete re-soldering of the system and replacement of all components. These refrigerants work with different pressures and oils. Attempting such a replacement will result in an explosion or fire.
Why does the new compressor run hotter than the old one?
Modern compressors often have a higher insulation class and operate at higher housing temperatures to increase efficiency. If the temperature does not exceed 80-90 degrees and there is an outflow of heat, this is normal.
How much does it cost to replace a compressor with Indesit?
The cost consists of the price of the unit itself (from 3 to 8 thousand rubles) and the work of the technician with consumables (freon, filter, soldering), which in total can be from 6 to 8 thousand 12 thousand rubles depending on the region.
The compressor is humming, but does not start - what to do?
Most likely, the starting relay has failed or the piston is jammed. Try gently knocking on the body of a running (humming) compressor, sometimes this helps to break a jammed piston, but this is a temporary measure.
Which compressor is the quietest?
Inverter models are considered the quietest, followed by compressors Danfoss/Secop with a low noise level. Classic piston engines Aspera work noticeably louder.
