The question about the number of compressors in refrigeration equipment often arises among those who have encountered breakdowns, noisy operation of the equipment, or are simply choosing a new model to purchase. Indesit refrigerator is a popular brand in the household appliances market that produces units of various configurations. Understanding how many motors are installed in your device is critical for correctly diagnosing faults and assessing energy consumption.
Most modern users are accustomed to the classic scheme, where one powerful unit is responsible for cooling. However, in the lines Indesit there are also more complex systems. In this article, we will analyze in detail the design of various models, explain the difference between single-compressor and double-compressor systems, and also help determine the type of equipment you have without calling a specialist.
It is worth noting right away that the number of motors directly affects the cost of repairs, the noise level and the ability to independently control the temperature in the chambers. Indesit refrigerators most often have one compressor installed, but models with a No Frost or full cooling system can be equipped with two units. Let's figure out how it works and what it does influences.
Types of compressor systems in Indesit technology
Brand engineering thought Indesit has developed in different directions, which led to the appearance on the market of devices with different cooling architectures. The main difference lies in the number of refrigerant circuits and pumps that serve them. Single-compressor system is the most common and economical in production. In such models, one motor pumps freon through a single circuit, which is then divided into evaporators of the freezer and refrigeration chambers.
In more expensive and modern series, especially those equipped with a system No Frost, a scheme with two compressors is often used. This allows for independent climate control. You can set deep freeze in the freezer and plus temperature in the main compartment, and these processes will not conflict. Double-compressor models are considered more reliable in terms of load distribution, since each motor works only on its own chamber.
⚠️ Attention: An attempt to independently replace a compressor in a dual-circuit system without the appropriate equipment for evacuation and refilling with freon will lead to irreversible damage to the refrigerator.
It is also worth mentioning inverter technologies that are beginning to be introduced into new brand lines. What is important here is not the quantity, but the principle of operation: such motors do not turn off completely, but smoothly regulate the power. This reduces the wear of mechanical parts and the noise level, although structurally there can be either one or two of them.
How to determine the number of compressors visually
The easiest way to find out how many “hearts” are beating in your refrigerator is to look behind its back. Typically, access to the technical compartment does not require disassembling the case, just move the unit away from the wall. Visual diagnostics gives almost 100% accuracy if you know what to look for. In classic models, you will see one black metal cylinder with tubes extending from it.
If you have a two-compressor model, the picture will be different. You will notice two separate blocks, often located next to each other or one on top of the other. Each of them will have its own set of copper tubes and, as a rule, a separate start relay. Models Indesit with a system Total No Frost most often belong to this type.
- 🔍 One motor: On the back wall there is one large black barrel (compressor) with a radiator grille next to it.
- 🔍 Two motors: Two are visible separate compressor units, often connected by a common frame or located in different niches.
- 🔍 Electronics: In two-compressor models, the control unit is usually more complex and has more wires going to different nodes.
Do not be confused compressor with fans. In systems No Frost you can hear the hum of fans that move air inside the chambers, but visually they are hidden behind plastic panels inside the cabinet, and not outside. The compressor is always located in the lower part at the back.
Single-compressor refrigerators: operating principle
The vast majority of refrigerators Indesitpresented on the CIS market belong to the single-compressor class. In such devices, the refrigerant circulates in a closed circle, passing through the condenser, capillary tube and evaporators. Solenoid valve redirects the flow of freon: first it cools the freezer chamber, and the remaining cold goes to the main compartment.
The main feature of this circuit — temperature dependence. You cannot completely turn off the freezer while leaving the refrigerator running, or vice versa, unless this is provided by the special “Vacation” function. The motor is turned on by a signal from a sensor in one of the chambers (usually in the freezer) and operates until the temperature there reaches a predetermined minimum.
The advantage of such models is their low cost of maintenance. It is cheaper to replace one compressor than two. In addition, they have fewer parts that can fail. However, there is also a minus: if a single motor breaks down, you are left without cold in all chambers at once.
Two-compressor models: independence and efficiency
Two-compressor refrigerators Indesit are, as a rule, devices in the middle and high price segment. A scheme is implemented here where each circuit operates autonomously. One compressor is responsible exclusively for the freezer compartment, and the second is responsible for the refrigerator compartment. This allows you to achieve more accurate temperature control and avoid temperature changes
Such a system is especially effective in large-volume models, where it is physically difficult for one motor to quickly cool a large displacement. Load sharing extends the service life of each individual unit. If one motor fails, the second will most likely continue to work, and some of the products can be saved.
⚠️ Attention: In dual-compressor models, noise can come from either of the two motors. To diagnose a faulty unit, it is necessary to listen to each compressor separately, placing your hand on the housing or using a stethoscope.
Energy consumption in such models may be higher, since two engines operate, but modern technologies make it possible to minimize this gap. Often, such refrigerators have a higher energy efficiency class due to precise climate control without wasting resources.
Comparative table of characteristics
To make it easier for you to navigate the differences, we have prepared a summary table. It will help you quickly evaluate the pros and cons of each system when choosing or analyzing current equipment.
| Characteristics | One compressor | Two compressors |
|---|---|---|
| Independence of chambers | Partial or absent | Full independence |
| Noise level | Average (one source) | May be higher (two sources) |
| Repair cost | Lower | Higher (more expensive parts and labor) |
| Energy consumption | Usually lower | Often higher |
| Speed defrosting | Longer (you need to wait for the entire circuit to defrost) | Faster (local defrosting) |
Diagnostics of compressor faults
Understanding how many motors are in your Indesithelps in initial diagnosis. If the refrigerator has stopped freezing, but is humming, the problem may lie in a loss of pump performance or a freon leak. In dual-compressor models, the symptoms may be strange: for example, there is ice in the freezer, but it is warm in the refrigerator. This is a direct sign that one of the compressors (or the switching valve) is not working.
A common problem is thermal relay. If the compressor tries to start, hums for a couple of seconds and clicks when it turns off, the starting device is most likely burned out or the piston is jammed. In models with one motor, this means a complete stop of the refrigerator. In models with two - stopping one of the chambers.
It is also worth paying attention to the temperature of the compressor housing. It should be hot, but not so hot that you can't touch it. If the motor Indesit works without a break for days, this may indicate a refrigerant leak or a leak in the system.
☑️ Primary diagnostics of the compressor
Repair and replacement: what the owner needs to know
Replacing the compressor is a complex technical procedure that requires qualifications. Unlike replacing a filter or light bulb, this requires working with refrigerants under pressure. Service center specialists they use nitrogen to purge the system, a vacuum pump to remove moisture and scales for accurate charging with freon.
If you are the owner of a two-compressor refrigerator, the cost repairs can be unpleasantly surprising. Often the price of a new compressor along with labor is 60-70% of the cost of a new budget refrigerator. Therefore, if the device is more than 7-10 years old, sometimes it is more advisable to buy new equipment than to reanimate the old one.
⚠️ Attention: Never try to connect compressor tubes without soldering with hard solder. Using clamps or glue will lead to an instant leak of freon and failure of the system.
When choosing a spare part, it is important to consider not only the brand, but also the characteristics: power, refrigerant (R134a or R600a), oil type. For Indesit universal compressors are often suitable, but their selection must be done by a specialist.
Is it possible to replace the compressor with an analogue of another brand?
Yes, you can. Compressors are standardized in terms of seating and power. The main thing is to match the type of refrigerant and performance. However, after replacement, the thermostat may need to be reset.
Frequently Asked Questions (FAQ)
Where is the model serial number to find out the type of compressor?
The serial number and full model can be found on a sticker inside the refrigerator compartment (usually on the left wall or ceiling) or on rear wall of the case. Using this code (for example, DS 320 W), you can find a technical data sheet on the manufacturer's website.
Is it true that two compressors are louder than one?
Not necessarily. Modern motors are very quiet. The noise may be more noticeable only when both units are started simultaneously, but this happens rarely, since their operating cycles are usually not synchronized.
Can one compressor in a two-engine refrigerator work, but the other does not?
Yes, this is possible if one of the components malfunctions. However, in some models, electronics can block the operation of the entire system if the sensor detects a critical error in one of the circuits.
How to extend the life of the compressor in an Indesit refrigerator?
The main rule is not to put hot foods inside and provide a gap of at least 5-10 cm between the back wall of the refrigerator and the kitchen wall for normal radiator ventilation.
