The situation when Indesit refrigerator stops turning off is an alarming signal for any owner of household appliances. Continuous operation of the motor not only leads to a significant increase in electricity bills, but also creates the risk of complete breakdown of an expensive unit in the very near future. A compressor operating without rest breaks experiences colossal overloads, which often ends in its combustion or jamming of the piston group.
Before you panic and call a technician, it is necessary to conduct an initial diagnosis to understand the scale of the problem. Often the cause is not a breakdown of the electronics, but a banal violation of operating rules or the tightness of the circuit. In this article, we will analyze in detail the main factors influencing the cyclic operation Indesit refrigeratorsand determine which components require your attention first.
Understanding the principle of operation cooling systems will help you quickly identify an anomaly. In normal mode, the unit reaches the set temperature, after which the thermostat sends a signal to stop the compressor. If this cycle is disrupted, it means that the cold either does not accumulate, or the sensors incorrectly read information about the microclimate inside the chambers.
Malfunctions of the thermoregulation system
The most common reason for the endless operation of the motor is the failure of the thermostat or electronic control module. It is this element that is responsible for controlling the temperature and making decisions about turning it on or off compressor. If the contacts inside the mechanical thermostat are stuck in the “closed” position, the circuit will not break, and the refrigerator will operate continuously, ignoring the achieved cold.
In models with a system No Frost and electronic control, the role of a thermostat is performed by air sensors (thermistors). Their readings may be distorted due to oxidation of the contacts or displacement of the sensor itself. If the sensor “thinks” that the chamber is warm, it will constantly require the control board to start cooling. Diagnostics of such elements requires a multimeter to measure resistance at different temperatures.
How to check a mechanical thermostat?
To check a mechanical thermostat, it must be removed. Place the thermostat sensing tube in a container of ice. If after 10-15 minutes there is no click and the contacts do not open (continuity check), the part is faulty and requires replacement.
It is also worth considering that in some older models Indesit the thermostat can be set to maximum cooling. Users often turn the handle all the way, not realizing that this makes the equipment work non-stop. The normal position of the regulator is usually in the middle of the scale or indicated by a green line.
Refrigerant leakage and seal failure
The second most common reason the refrigerator does not turn offlies in the physical inability of the system to reach the desired temperature due to a lack of freon. Refrigerant leakage can occur through microcracks in the evaporator, corrosion of condenser tubes, or poor-quality factory soldering. When there is little gas in the circuit, the pressure drops, and the compressor is forced to work around the clock, trying to compensate for the lack of cooling capacity.
It is almost impossible to determine the leak visually, since freon has neither color nor smell. However, there are indirect signs indicating depressurization of the system. If you notice that the freezer has stopped freezing, and the ice “coat” has disappeared on the back wall of the main chamber or, conversely, warm areas have appeared, this is a sure sign.
- 🧊 Lack of cold: food in the main chamber has begun to deteriorate, although the freezer is still working.
- 🔊 Operation noise: compressor hums continuously, without characteristic rest pauses.
- 🔥 Condenser heating: the grille at the back of the refrigerator is either barely warm or hot evenly along its entire length.
- 💧 Wall swelling: at the point of leakage (often inside the foamed casing) can swell insulation.
⚠️ Attention: Refilling the refrigerator yourself with freon without finding and eliminating the leak is a temporary measure that will only delay the breakdown. The freon will escape through the hole again, and the compressor will burn out from working in a vacuum or moisture entering the system.
If a leak is confirmed, you need to call a technician with equipment to find the fistula, pressurize the system with nitrogen and then refill it. In some cases, if the foamed evaporator is corroded, repair may not be economically feasible.
Problems with sealing rubber bands
The tightness of the refrigeration chamber directly depends on the condition sealing cuffs on the doors. If the elastic band has aged, lost elasticity, cracked, or simply does not fit tightly due to contamination, warm air from the room constantly enters the chamber. Sensors detect an increase in temperature and force the compressor to work without stopping to cool the incoming heat.
You can check the tightness of the seal by simple visual inspection and tactile method. Run your hand along the perimeter of the closed door - you should not feel any flow of cold air coming out. A test with a sheet of paper is also effective: clamp the sheet with a door in different places; if it falls out or is pulled out without resistance, the seal is broken.
Often the problem is solved by thoroughly washing the seal with warm water and soap, since grease and sticky food debris interfere with tight contact. If the elastic band is deformed, you can try to restore its shape by heating it with a hairdryer or placing a tourniquet in the area where it is loose. As a last resort, you will need replacement of the seal a new one.
Malfunctions of the control module and sensors
In modern models Indesit with electronic control, the control module is responsible for all processes. If the compressor turn-on relay burns out on the board or a software failure occurs, the unit may go into emergency mode of continuous operation. The electronics stops receiving correct data from the sensors or ignores their signals.
Board diagnostics require special knowledge and equipment. Often problems with electronics are indicated by a flashing temperature indicator or an error code on the display (if provided by the model). In such cases, attempting to repair it yourself can lead to more serious damage to expensive components.
It is also worth checking the integrity of the wiring going to the sensors. A broken wire or oxidized connector can give a false signal about “heat” in the chamber. Pay special attention to the places where the wires bend in door hinges, where the insulation often wears out over time.
| Symptom | Possible cause | Action |
|---|---|---|
| Alarm indicator is on | Electronics or sensor failure | Reboot or replace sensor |
| Compressor is hot | Overload or leakage | Checking freon pressure |
| Ice only at the entrance of the tubes | Lack of freon | Searching for leaks and refueling |
| Relay clicks, but no start | Faulty start relay | Replacing the compressor relay |
The influence of external factors and improper operation
Sometimes the reason lies not in the breakdown, but in the operating conditions. If Indesit refrigerator is installed near heating devices, in direct sunlight or in a niche without proper ventilation, it will work at its limit. Heat exchange is disrupted, and the equipment cannot return to normal mode.
Loading warm products also causes the motor to run for a long time. If you put a pot of hot soup in the chamber, the refrigerator will have to work for hours to compensate for the sudden temperature increase. This is not a breakdown, but a normal, albeit energy-intensive, reaction of the system.
Do not forget about the seasonal factor. In summer, when the room temperature reaches +28...+30°C, the compressor operating time naturally increases. However, it should still turn off periodically. If there are no pauses at all, look for a malfunction.
☑️ Checking the installation conditions
Self-diagnosis algorithm
To narrow down the troubleshooting, we suggest using a step-by-step algorithm. He will help you understand whether you can solve the problem yourself or whether you need to call a specialist. Remember that safety comes first: carry out any manipulations with electrical circuits only when the device is disconnected from the network.
Start with defrosting. Defrost the refrigerator completely within 10-12 hours with the doors open. This will eliminate the possibility of blocking the capillary tube with ice (the so-called “ice jam”). After connecting to the network, monitor the operating cycles: if in the first couple of hours it turns off and then starts working again without stopping, the problem is deeper.
Pay attention to the sounds. A dull hum may indicate the compressor is working, but a quiet hissing or gurgling may indicate active movement of freon or its absence. If the compressor hums but does not start (a clicking and humming noise is heard), the motor may be stuck or the start relay has failed.
⚠️ Attention: Do not attempt to repair a sealed circuit or change the compressor yourself without skills and a vacuum pump. Incorrect soldering or moisture getting inside the system will lead to the final failure of the equipment.
If the problem persists after defrosting and checking the seals, most likely it is a freon leak or an electronics malfunction. In this case, further self-diagnosis is limited to a visual inspection.
Frequently asked questions (FAQ)
Can the refrigerator work without interruption immediately after being turned on?
Yes, when turned on for the first time or after a long defrost Indesit refrigerator can work without shutdown from 3 to 8 hours. This is necessary for the initial temperature set and freezing of products. The alarm should be raised if the non-stop mode persists for more than 12 hours.
What to do if the compressor is hot but there is no cold?
A hot compressor in the absence of cold most often indicates freon leak or blockage of the capillary system. The compressor idles, trying to pump gas that is not there or that is not circulating. A call to a technician is required to diagnose the pressure.
How often should a working refrigerator turn off?
Under normal conditions, the compressor operating coefficient is about 40-50%. This means that for every 10-15 minutes of work there should be 10-15 minutes of downtime. In the summer or when fully loaded, the operating time may increase, but pauses must be required.
Does the number of products affect the operating time?
Yes, a full load of products (especially warm ones) increases the heat load, and refrigerator will work longer. However, an empty refrigerator can also work longer due to the small volume of heat-intensive bodies that stabilize the temperature. The average load is optimal.
