Refrigeration equipment brand Indesit deservedly enjoys popularity due to its accessibility and simplicity of design, however, even reliable equipment fails over time. Owners often encounter situations when the unit stops freezing, begins to make strange sounds, or becomes covered with a crust of ice. Understanding the nature of these breakdowns allows you not only to save on service center services, but also to prevent damage to products.
Most problems that arise during operation can be classified according to the main components: the cooling system, electrical circuit or mechanical damage. Timely diagnosis helps determine whether complex replacement of components is required or simple adjustment is sufficient. In this article we will analyze in detail the main symptoms indicating specific malfunctions.
It is worth noting that ignoring the primary signs of failure often leads to the failure of more expensive parts. For example, an intermittent thermostat can cause overload and combustion. compressor. Therefore, at the first signs of unstable operation, a careful visual and acoustic inspection of the device should be carried out.
Problems with starting and operating the compressor
The compressor is the heart of the refrigeration unit, ensuring the circulation of the refrigerant. If you notice that Indesit refrigerator the engine is humming but not cooling, or the engine does not start at all, the problem may lie in the start relay or the engine itself. A common occurrence for models with one compressor is the situation when the motor tries to start, makes a click and immediately stalls.
In such cases, the culprit is most often starting relay, which is responsible for starting the motor windings. Over time, the contacts inside the relay oxidize or burn, preventing normal starting. Replacing this part usually does not require special equipment and can be done independently with basic skills.
⚠️ Attention: If, after replacing the relay, the compressor makes a loud metallic knock when trying to start and immediately turns off, the piston group is likely to be wedged. Further attempts to turn on may lead to final combustion of the windings.
A more serious problem is the failure of the compressor itself. This can happen due to power surges or normal wear and tear. In this case, the unit is either silent or hums continuously, without creating the necessary pressure in the system. Diagnostics requires using a pressure gauge and checking the resistance of the windings with a tester.
Malfunctions of the defrost system and ice formation
Modern models Indesit with a system No Frost or static cooling are susceptible to malfunctions in the defrost system. If you find that the back wall of the chamber is covered with a thick layer of ice, and there is water at the bottom of the refrigerator, then the defrosting cycle is broken. This is one of the most common reasons for calling for service.
The main elements that require checking are the evaporator heating element, defrost sensor and timer (or electronic control module). The heating element may burn out and stop heating the radiator, which is why the ice does not melt and blocks the air circulation channels. The heater is checked by checking the continuity with a multimeter for an open circuit.
- 🧊 Defrost heating element —a heating element that turns on periodically to melt the ice on the evaporator.
- 🌡️ Defrost sensor—monitors the temperature of the evaporator and turns off the heating element when all the ice is will melt.
- ⏱️ Timer or module - controls the switching of the “cooling” and “defrosting” modes.
If the heating element is working, but the problem persists, you should check the defrost sensor. In some models, it may “stick” in the “heating” position, which leads to a constant increase in the temperature in the chamber, or in the “cooling” position, which leads to ice accumulation. Replacing the sensor often solves the problem of excess icing.
Refrigerant leakage and leakage
The situation when the refrigerator Indesit works constantly, the compressor does not turn off, but the temperature inside the chamber does not drop below +10...+15 degrees, often indicates a leak Freon. The refrigerant can escape through microcracks in the evaporator, which are formed due to corrosion, or through poor-quality factory connections.
Detecting a leak visually is quite difficult, since freon is colorless and odorless. However, indirect signs are swelling on the inner wall of the refrigeration chamber (if the evaporator is baked in foam) or characteristic oily spots at the site of damage to the circuit. Tightness of the system is a critical parameter for the operation of the unit.
| Symptom | Probable cause | Solution method |
|---|---|---|
| The compressor runs non-stop | Freon leak or capillary tube clogged | Searching for leaks, vacuuming, refilling |
| The refrigerator is silent, there is no light | Open circuit or lack of power | Checking the socket and cable |
| The sound of pouring water is heard | Normal circulation of the refrigerant | Observation required |
| Ice only at the back wall | Failure of the door or seal | Replacing the seal, adjusting the door |
Restoring tightness requires specialized equipment: nitrogen for crimping, vacuum pump and scales for precise refilling of freon. It is almost impossible to independently eliminate a leak in a foamed evaporator without compromising the integrity of the housing, so in such cases a decision is often made to install an external evaporator (“crying” or mounted).
Failures of the thermostat and electronic module
The thermostat (thermostat) is responsible for maintaining the set temperature inside the chambers. If the refrigerator Indesit stops turning off or, conversely, does not turn on at all, this particular unit is checked first. In mechanical models, this is a device with a capillary tube that responds to temperature changes.
If the thermostat malfunctions, the contacts may not close and the compressor will not receive a signal to start. Or the contacts will “stick” in the closed state, forcing the motor to run continuously, which leads to deep freezing of the food. Replacing a thermostat is a simple procedure, but requires precise selection of an analogue for a specific model.
In models with electronic control, thermoregulation functions are performed by electronic module. Malfunctions in its operation can be caused by voltage surges, moisture ingress or oxidation of contacts. A symptom of a board failure is often chaotic behavior of indicators, erroneous codes on the display or a complete lack of response to control buttons.
How to check a thermostat with a multimeter?
To check, you need to remove the thermostat, immerse its sensitive tube in cold water with ice and ring contacts. If during cooling the contacts do not open (or do not close, depending on the type), the part is faulty.
Wear of seals and problems with the door
A tight fit of the door is the key to efficient operation of the refrigerator. If the rubber seal is worn out, deformed or dirty, warm, moist air constantly enters the chamber. This leads to increased formation of ice, increased load on the compressor and increased energy consumption.
You can check the tightness in a simple way: close the door on a sheet of paper. If the sheet is removed without resistance at different points around the perimeter, it means the seal is broken. It is also worth paying attention to the door hinges: if they are loose, the door warps and does not fit tightly even to the new seal.
- 🧼 Wipe the seal regularly with a soft cloth to remove grease and crumbs.
- 🔥 You can try to straighten minor deformations of the rubber with a hot hairdryer.
- 🔧 If there is severe wear, a complete replacement of the sealing tape is required.
Ignoring the problem with the door can lead to the No Frost system no longer coping with moisture, and the entire volume of the chamber will be covered a coat of ice. In models Indesit replacing the seal often requires removing the door, since the tape can be glued or installed in a complex groove.
Noise, vibration and extraneous sounds
The refrigerator is not a silent device, but the nature of the sounds can tell about its condition. A smooth hum of the compressor and a quiet gurgle of freon is considered normal. However, if you hear a loud knocking, grinding or whistling sound, this is a sign of mechanical failure.
A loud knocking often indicates that the compressor is "tired" and its shock absorbers are worn out, or the piston has struck the valve group. The motor-compressor can make a whistling sound when operating at maximum capacity due to high pressure in the system. Vibration of the housing is usually associated with improper installation of the unit.
⚠️ Attention: If the refrigerator emits a high-pitched whistle immediately after the compressor stops, this may indicate air is being sucked in through leaks in the system, which is unacceptable for the operation of the freon circuit.
To eliminate vibration, it is necessary to check the adjusting supports. They must be unscrewed so that the body is stable and does not wobble when pressed lightly. Also check whether the condenser tubes on the rear wall are touching each other or the housing - this causes rattling.

Frequently asked questions (FAQ)
Why does the Indesit refrigerator get very hot on the sides?
Heating of the side walls is a normal process for many models Indesit. These areas contain condenser tubes that release heat to the environment. If the heating is moderate and uniform, there is no need to worry. Only excessive overheating, which cannot be touched, should cause alarm.
What to do if there is water in the refrigerator compartment, but everything is frozen in the freezer?
Most likely, the drainage channel for removing melt water is clogged. The ice plug prevents water from going into the tray above the compressor, and it flows out. It is necessary to defrost the refrigerator and clean the hole with a soft wire or a syringe with warm water.
Is it possible to operate the refrigerator if it makes clicks?
Single clicks when turning on and off are the work of the thermostat or thermal expansion of materials. However, frequent clicking sounds during the starting cycle (click - hum - click) indicate a faulty start relay or problems with the compressor. Operation in this mode is dangerous due to motor combustion.
How long does the compressor last in the Indesit refrigerator?
The average service life of the compressor is 10–15 years, provided there is a stable voltage in the network and proper operation. However, the quality of assembly and operating conditions (for example, dustiness of the condenser) can significantly reduce this resource.
