The situation when the refrigerator Indesit suddenly stops freezing takes any home cook by surprise, because this threatens food spoilage. Users often notice a problem when it becomes warm in the main chamber and the ice in the freezer begins to melt. This is an alarming signal that requires immediate intervention and diagnosis.
The Italian brand Indesit is famous for its reliability, but even high-quality equipment breaks down over time. The cause may be either a simple network overload or a serious malfunction compressor or a refrigerant leak. Understanding the nature of the breakdown will help you make the right decision: call a technician or try to fix the defect yourself.
In this article we will analyze in detail all the possible reasons for the lack of cold in double-chamber and single-chamber models. You will learn how to carry out primary diagnostics, which components to pay attention to first and what to do if the unit hums but does not cool. The most common reason for the complete loss of cold in older models is a failure of the start relay or a freon leak.
Primary diagnostics: why is it warm in the chamber
Before disassembling the equipment, it is necessary to eliminate external factors that are often mistaken for failure. If your Indesit stops freezing, first check the tightness of the door. A door that is not tightly closed allows warm air to pass through, causing the compressor to work harder, but not creating the desired temperature.
Pay attention to the operating mode. Perhaps someone in the household accidentally turned the regulator to the “Off” or “Min” position. It is also worth checking whether you have loaded a large amount of warm food into the chamber at once. In this case, the unit needs time to restore the temperature.
If you make sure that the door is closed tightly, the modes are set correctly, and the food was cold, but the cold still disappears, the problem lies within the system. It is worth listening to the operation of the engine: is it humming, clicking, or is there complete silence. These sounds are the key to understanding which unit has failed.
It is important to distinguish between situations when the equipment does not cool at all, and when the temperature is simply higher than normal. In the first case, the lack of refrigerant is often to blame. In the second case, the problem may be in the thermostat or a clogged capillary tube. Accurate diagnostics begins with analyzing the behavior of the unit in the first minutes after switching on. compressor or lack of refrigerant.

Problems with the No Frost and defrosting system
Many modern models Indesit equipped with a system No Frostthat prevents the formation of ice. If such a refrigerator has stopped freezing, but the motor is running, the reason often lies in the defrost system. Ice could block the channels through which cold air circulates from the freezer to the refrigerator compartment.
Several elements are involved in the automatic defrosting system: a heating element (heating element), a defrost sensor and a timer. If the heating element burns out, the ice does not melt, the evaporator becomes overgrown with a “fur coat”, and the fan stops moving air. As a result, the main chamber is warm, but the freezer may be colder than usual due to the insulation of the evaporator by ice.
⚠️ Attention: Attempting to break off the ice with a knife or sharp objects in the No Frost system is strictly prohibited. You can damage the thin evaporator tubes or fan blades, which will lead to costly repairs.
Checking the defrosting system often requires partial disassembly of the freezer. You need to get to the evaporator and check the integrity of the heating element with a multimeter. The defrost sensor is also checked, which should open the circuit when a certain temperature is reached. A malfunction of any of these elements stops the cooling cycle.
☑️ Diagnostics of the No Frost system
If you find that the fan does not spin, check whether ice is preventing it. Sometimes it is enough to completely defrost the refrigerator within 24 hours for the system to work again. However, if the problem recurs, replacing the burnt out element is inevitable.
Faults of the compressor and start relay
The compressor is the heart of the refrigerator Indesit. If it doesn't start, there won't be any cold anywhere. You can often hear a characteristic click, after which the engine tries to start, hums for a few seconds and clicks again, falling silent. This is a classic sign of a malfunction start relay or jammed compressor.
The start relay is a small plastic block that is attached to the side of the compressor. Inside it there is a coil and contacts that provide an impulse to start the engine. Over time, the contacts may burn out and the mechanism may jam. Replacing the relay is one of the simplest and cheapest repair procedures that you can do yourself.
If after replacing the relay the situation has not changed and the compressor still hums and turns off, there may be a break in the motor winding or a mechanical jamming of the piston group. In this case, the compressor itself must be replaced, which is a complex procedure that requires evacuation of the system and charging with freon.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Silence, no buzzing | Open circuit, thermostat, relay | Low |
| Clicking and buzzing 5-10 sec | Start relay, compressor wedge | Medium |
| Humming constantly, not cooling | Freon leak, blockage | High |
| Strong knocking during operation | Destruction of the compressor suspension | High |
When diagnosing the motor, it is important to check whether it is overheating. If the compressor is hot to the touch, but does not start fully, this may indicate an interturn short circuit in the windings. In such cases, operating the equipment is dangerous and can lead to a fire.
Freon leakage and clogged capillary tube
If the compressor operates continuously, hums smoothly, but there is no cold, most likely the balance in the circulation system is disturbed. Two main reasons: a refrigerant (freon) leak or a clogged capillary tube. Freon is a working fluid that transfers heat. Without it, the compressor simply runs empty.
Leaks in refrigerators Indesit often occur in the foamed part of the body or in the heating circuit around the door perimeter. It is impossible to locate the leak visually; the use of a leak detector is required. If the freon is gone, the system needs to be evacuation, searching for the fistula, sealing it and refilling it.
Why can’t you just add freon?
Simple refilling without looking for leaks and evacuation will not give a long-term effect. The air and moisture remaining in the system will lead to corrosion and failure of the compressor within several months.
Clogging of the capillary tube occurs due to moisture or oil breakdown products entering the system. The tube has a very small diameter, and any foreign particle can block the freon flow. In this case, the compressor tries to push gas, working with increased load, and the condenser (grid at the back) remains only partially cold or warm.
It is difficult to diagnose these problems at home. If you notice that the refrigerator is running non-stop and the temperature does not drop, it is better not to delay calling a technician. Prolonged idle operation of the compressor can lead to overheating and combustion.
Failure of the electronics and thermostat
In models with electronic control, control moduleis responsible for the operation of all components. If the display shows errors or the lights are blinking, the problem may be with the board. Power surges in the network often cause failure of the electronic components that control the compressor or fan.
In simpler models with mechanical control, the thermostat (thermostat) plays the role of a controller. This device opens the electrical circuit when the desired temperature is reached in the chamber. If the thermostat contacts have oxidized or the bellows has lost its seal, the circuit does not close and the compressor does not receive a start signal.
You can check the thermostat by closing its contacts directly (for diagnostics). If the refrigerator starts working after this, it means that the regulator is faulty and requires replacement. In two-chamber models, the thermostat is usually located in the refrigerator compartment, and its sensor responds to the air temperature there.
⚠️ Attention: When replacing the thermostat or any electrical work, be sure to unplug the refrigerator. Do not carry out diagnostics under voltage unless you have the appropriate skills and tools.
It is also worth checking the integrity of the wiring. Rodents or mechanical damage during transportation could break the wires going to the motor or lamp. Visual inspection of wiring harnesses in accessible places can save time on troubleshooting.
When you need to call a technician
Not all breakdowns can be fixed with your own hands. If diagnostics indicate a freon leak, a clogged system, or the need to replace the compressor, you cannot do without a specialist and specialized equipment. These works require soldering skills, the use of a vacuum pump and scales to accurately charge the refrigerant.
In addition, if the refrigerator Indesit is under warranty, independent intervention will deprive you of the right to free repairs. Even after the warranty period has expired, it is better to entrust complex repairs to professionals, so as not to aggravate the situation and damage adjacent components.
The cost of repairs varies depending on the complexity. Replacing a thermostat or relay will not cost much, while overcooking the system or replacing the motor-compressor will require significant costs. Sometimes, in the case of very old models, repairs may not be economically feasible.
If you decide to call a technician, ask for a guarantee on the work performed and the spare parts used. This will protect you from poor-quality repairs and repeated breakdowns in the near future. A good specialist will always explain the cause of the breakdown and show you the replaced parts.
Prevention and operating rules
To ensure that your Indesit serves for a long time and does not stop freezing at the wrong time, follow simple operating rules. Do not place hot foods in the chamber; let them cool to room temperature. This reduces the load on the compressor and prevents excessive condensation.
Regularly defrost the refrigerator if it is not equipped with a No Frost system. Even in systems with automatic defrosting, it is recommended to completely defrost and wash the internal surfaces once a year. This will help avoid blockages in the drainage hole and unpleasant odors.
Keep the condenser grille at the back of the refrigerator clean. Dust and pet hair, settling on the tubes, worsen heat transfer, causing the motor to work more intensely. You need to vacuum the grille carefully so as not to damage the thin tubes.
It is also important to ensure proper installation of equipment. The refrigerator should stand level, with a gap to the wall for air circulation. Installation near heating devices or in direct sunlight, which creates a thermal load, is not allowed.
Why does the refrigerator freeze but does not turn off?
Continuous operation of the compressor without turning off may indicate a freon leak, wear on the door seal, or a malfunction of the thermostat. The unit is trying to gain temperature, but heat is constantly coming from outside or the refrigerant is not enough for effective cooling.
Is it possible to use a refrigerator if it does not freeze well?
It is not recommended to operate the equipment in this mode. The compressor operates at its limit, which leads to overheating and rapid wear. In addition, in conditions of insufficient cold, bacteria can begin to multiply in products.
How often do you need to change the rubber seal?
The seal is changed as it wears out: if it is cracked, becomes hard, or does not provide a tight fit. On average, the service life of an elastic band is 5-7 years, but with proper care it can last longer.
