The situation when Indesit refrigerator stops turning off is an alarming signal for any owner. Instead of the usual rhythmic hum, followed by silence, the unit begins to work non-stop, trying to achieve the set temperature indicators. This not only leads to a sharp jump in electricity bills, but also creates the risk of complete failure of the compressor due to overheating.
Most often the problem lies in a violation of heat exchange or a failure in the control system. Italian appliances Indesit famous for its reliability, but even the highest quality components have properties wear out. Understanding why your refrigerator humming around the clock will help you make the right decision: call a technician or try to fix the problem yourself.
In this article we will analyze in detail the mechanical and electrical reasons for continuous operation, and also consider typical errors operation. It is critically important not to ignore the first signs of compressor overheating, since replacing it can cost up to 70% of the cost of a new device. Let's figure out what exactly makes the motor work without rest.
Violation of tightness and thermal insulation
One One of the most common reasons why Indesit refrigerator does not turn off is a violation of the seal of the chamber. If warm air from the room enters inside, the temperature inside rises, and the sensors command the compressor to work more actively. First of all, you should check the condition rubber seal on the door. Over time, the rubber dries out, cracks, or simply becomes dirty, no longer fitting tightly to the body.
It is also worth paying attention to the door hinges. If they are loose or warped, the door will not close tightly, even if the seal is in good condition. You can check the tightness in a simple way: hold a sheet of paper between the door and the body and try to pull it out. If the paper comes out easily, it means the seal is brokenthat the cold is escaping.
Do not forget about the frequency of opening the door. If you often look inside or leave the door open while cooking, refrigerator the air volume simply does not have time to cool. In this case, the equipment works properly, but the load on it increases many times over.
- 🧊 Check the rubber seal around the entire perimeter of the door for cracks and dirt.
- 🚪 Make sure that the door closes tightly and is not skewed relative to the body.
- 🔥 Assess the distance to heating devices: radiators and stoves should not heat the walls.
- 🌡️ Measure the temperature in the room: if above +30°C, the refrigerator will work longer.
⚠️ Attention: If you find that the seal is deformed, do not rush to change it. Sometimes treatment with hot water or a hairdryer helps restore shape, but only if the rubber does not have physical breaks.
Malfunctions of the defrosting system (No Frost)
For models with the system No Frost the problem of the formation of a “snow coat” on the evaporator is typical, if the defrost system fails. In normal operating mode Indesit refrigerator periodically starts the heating element (heating element) to melt the frost. If this process is disrupted, the ice crust grows and blocks the circulation of cold air.
As a result, the temperature sensor in the refrigerator compartment “does not see” the cold, since the air flow is blocked by ice, and commands the compressor to work continuously. The compressor hums, trying to cool the chamber, but physically cannot do this due to the ice plug. In such cases, you can often notice that the food in the freezer is frozen, and there is heat in the refrigerator compartment.
The main culprits here are the defrost sensor or timer (control module). If the heating element burns out, the ice does not melt. If the sensor “lies” and shows that there is no ice (or vice versa, that it has already melted ahead of time), the defrosting cycle will not start correctly. Defrosting heating element, defrost sensor or timer (control module). If the heating element burns out, the ice does not melt. If the sensor “lies” and shows that there is no ice (or, conversely, that it has already melted ahead of time), the defrosting cycle will not start correctly.
How to diagnose a problem with defrosting?
For accurate diagnosis, you will need a multimeter. It is necessary to “ring” the heating element for resistance. If the device shows a break (infinity), the heating element is faulty and requires replacement. The integrity of the defrost sensor at low temperatures is also checked.
Symptoms of a faulty defrost system often appear cyclically. At first unit it works for a couple of days without a break, then you defrost it manually for a day, and it again starts to freeze normally and turn off. A few days later, history repeats itself. This is a sure sign that the automatic defrost is not functioning.
Refrigerant leak and problems with the compressor
If Indesit refrigerator the hum continues, but the cold inside is getting less and less, there is a high probability of a leak Freon. The refrigerant circulates in a closed circuit, and if a microcrack forms in the tubes or condenser, the gas gradually evaporates. The compressor tries to compensate for the lack of cold, working at its limit, but cannot reach the desired temperature.
Leakage can be caused by metal corrosion (especially in models with a foamed evaporator), mechanical damage during transportation or poor-quality factory soldering. It is difficult to visually notice a leak, since freon is colorless and odorless. However, an indirect sign may be swelling of the side wall or the appearance of rusty spots at the exit of the tubes.
Another serious problem is the compressor or loss of its performance. The motor may hum, but not create the necessary pressure in the system. In this case, replacing the compressor is inevitable. It is important to note that long-term non-stop operation in itself can lead to engine jamming. piston sticking compressor or loss of performance. The motor may hum, but not create the necessary pressure in the system. In this case, replacing the compressor is inevitable. It is important to note that long-term non-stop operation in itself can lead to jamming of the motor.
| Symptom | Probable cause | Nature of motor operation |
|---|---|---|
| There is cold, but weak | Freon leakage | Works without stopping, gets warm |
| There is no cold at all | The capillary is clogged or the compressor is faulty | Buzzes or clicks, but does not start |
| Periodic clicks | Faulty starting relay | Tries to start and stalls |
| Ice in the chamber No Frost | Failure of the defrost system | Works continuously, makes noise |
⚠️ Attention: Independent refilling of the refrigerator with freon is impossible without special equipment and a license. If you suspect a leak or breakdown of the compressor, you need to call a specialist.
Failure of the thermostat and electronics
The thermostat (thermostat) is the “brain” that decides when to turn it on and when to turn it off compressor. If this sensor fails and is stuck in the on position, the refrigerator will run indefinitely, even if ice has already formed inside. In mechanical models, the thermostat is a simple design with a bellows that responds to gas expansion.
In modern models Indesit with electronic control, the air sensor and control module are responsible for the temperature. If the sensor transmits incorrect data (for example, it shows +10°C, although it really is +2°C), the control board will keep the compressor on. Electronics are more sensitive to voltage surges, which can lead to failures in the operating logic.
You can check a mechanical thermostat by temporarily closing its contacts. If after this procedure refrigerator it starts working and starts to turn off (at least through an emergency timer), then the problem is in the sensor. In electronic models, diagnostics are carried out by measuring the resistance of the sensor with a multimeter at different temperatures.
- 🔧 Check the temperature settings: the “Super Freeze” mode may have been accidentally set.
- 📉 Listen to the clicks: a working thermostat should click when changing mode.
- 🌡️ Compare the sensor readings with reality using an external thermometer.
- 🔌 Try resetting the electronics by unplugging the device for 15 minutes.
The influence of external factors and operating conditions
Sometimes the reason for continuous operation lies not in a breakdown, but in incorrect operating conditions. Indesit refrigerator, like any other equipment, has a climate class. If you install the unit in an unheated garage or on a balcony, where the temperature drops below +10°C or rises above +32°C, it will not be able to work correctly.
At low temperatures, the oil in the compressor thickens, and freon ceases to condense effectively. At high temperatures, heat exchange is disrupted and the motor overheats. It is also important to leave space around the back wall and sides for ventilation. If refrigerator is pressed tightly against the wall or built into a niche without gaps, it will suffocate from its own heat.
Another factor is the presence of hot foods. If you put a pot of soup in the chamber, the refrigerator will work hard until it cools this volume. This is normal for a short-term load, but constant practice harms the equipment.
Check that water has not entered the back panel where the electrical components are located. Humidity can cause short circuits or corrosion of contacts, which leads to chaotic operation of the equipment.
Diagnostics and procedure for failure
If you are faced with the fact that refrigerator stopped turning off, do not panic. Start with simple steps that can be done without tools. First of all, carry out a visual inspection and defrosting. Even if you have a No Frost system, complete defrosting within 24 hours will help eliminate ice blockage in the channels.
After defrosting, turn on the empty refrigerator and observe its operation cycle. If it got hot and turned off, the problem was with the ice or food. If it works again without stopping, more in-depth diagnostics will be required. Check the tightness of the door and the cleanliness of the condenser (grids on the back).
☑️ Primary diagnostics of the refrigerator
It is important to understand when it’s time to call a technician. If the problem persists after defrosting and checking the settings, it is most likely due to a freon leak, compressor failure, or electronics failure. These components require professional repair.
⚠️ Attention: If you smell burning or see sparking in the compressor area, immediately unplug the device. Further operation may result in a fire.
FAQ: Frequently asked questions
How long should an Indesit refrigerator operate normally?
Under normal conditions refrigerator works about 30-40% of the total time (approximately 8-12 hours a day). However, in hot weather or when fully loaded, this figure can reach 60-70%. If it works more than 20 hours a day without breaks, it is a malfunction.
Is it possible to operate a refrigerator if it does not turn off?
For a short time (several hours) - it is possible, but this is an emergency mode. Long-term operation without stopping will lead to overheating of the compressor windings, drying out of the oil, and other jamming of the motor. The service life of the equipment is reduced significantly.
Why did the refrigerator stop turning off again after defrosting?
This indicates that the reason is not an ice jam. Most likely, there is a freon leak, the thermostat has failed, or the compressor has lost performance. Professional diagnostics with a pressure gauge are required.
What does it mean if the compressor is hot, but the cold is not coming out?
This is a classic sign of a refrigerant leak or capillary tube blockage. There is little freon in the system; it heats up in the compressor, but cannot effectively cool the evaporator. Refilling and searching for the leak are necessary.
Is it possible to replace the thermostat yourself?
In mechanical models - yes, if you have skills in working with electricians and tools. In models with electronic control, replacing sensors requires disassembling the case and often reflashing or configuring the module, which is best left to a specialist.
