The situation when the refrigerator Indesit works without stopping, ignoring the set temperature regime, is a serious signal for the owner. Continuous operation of the compressor not only leads to a significant increase in electricity bills, but also creates the risk of early failure of the engine itself. In normal mode, the unit should turn on and off cyclically, maintaining cold inside the chambers.
If you notice that your Indesit hums around the clock, and a “coat” of ice forms on the evaporator or the walls of the chambers, you need to urgently look for the cause. Often the problem lies in a violation of the tightness of the circuit or failures in the control electronics. Ignoring the first symptoms can lead to expensive repairs or complete replacement of equipment.
In this article we will analyze in detail the main reasons why the refrigerator Indesit does not turn off, and we will explain what actions need to be taken first. Diagnostics should be carried out sequentially, starting from simple settings and ending with checking complex ones nodes.
Malfunctions of the thermostat and temperature sensors
One of the most common reasons why the refrigerator Indesit stops turning off is the failure of thermostat (thermostat). This mechanical or electronic component is responsible for signaling the compressor to stop when the set temperature is reached. If the contacts inside the thermostat “stick” in the closed position, the motor will work endlessly.
In models with a system No Frost or Total No Frost electronic sensors are responsible for temperature control. Their readings may be distorted due to oxidation of contacts or physical damage. If the sensor “lies” and tells the control unit that the chamber is warm, the compressor will work, trying to cool the space, which is actually already frozen.
⚠️ Attention: Replacing the thermostat in refrigerators Indesit often requires partial defrosting and access to the internal mechanisms. If you are not confident in your electrical skills, it is better to entrust this procedure to a professional.
To check the mechanical thermostat, you can try to temporarily close its contacts. If after this manipulation the refrigerator continues to work the same, then the problem is not in it. In the case of electronic sensors, it is required testing with a multimeter at different temperatures.
Problems with the defrosting system and freezing of ice
In refrigerators Indesitequipped with an automatic defrosting system, critical The timer also plays a role. If the heating element burns out, the ice that forms on the evaporator while the compressor is running stops melting. Over time, the ice coat grows and begins to block the air channels. Defrost heating element and timer. If the heating element burns out, the ice that forms on the evaporator while the compressor is running stops melting. Over time, the ice coat grows and begins to block the air channels.
As a result, cold air stops circulating through the chambers, and temperature sensors record an increase in degrees. The control unit, receiving this data, commands the compressor to work harder and longer. As a result, the refrigerator Indesit works without interruption, trying to compensate for the lack of cold, although in fact the evaporator is frozen.
- ❄️ Signs of malfunction: a thick layer of ice is visible on the back wall, there is water at the bottom of the freezer, the compressor is hot.
- 🔊 Sounds: you may hear the cracking of ice or the noise of a fan that touches the ice crust.
- 🌡️ Temperature: it is warm in the main chamber, although the freezer can work normally.
The solution to the problem is to completely defrost the unit for at least 24 hours. If, after turning on, the refrigerator begins to operate in normal cyclic mode, then the problem lies in the defrosting system. However, to completely eliminate the malfunction, you will need to replace the burnt one Heating element or check the defrost control circuit.
Refrigerant leak and leakage
If the refrigerator Indesit does not turn off, but The temperature inside the chambers is higher than normal, there is a high probability of freon leakage. The refrigerant circulates in a closed circuit, and if its tightness is broken, the amount of working substance decreases. The compressor tries to compensate for the lack of freon by increasing the operating time.
Leakage can occur in places where tubes are soldered, in the foamed part of the housing, or through microcracks in the evaporator. Often, owners themselves damage the circuit when trying to defrost the freezer with a knife or sharp objects. In this case, the refrigerator will work constantly, but will not produce cold.
| Symptom | Probable cause | Action |
|---|---|---|
| Compressor is hot, cold is weak | Partial leak freon | Call a technician to find a leak |
| The engine runs, but does not heat up | Complete leak or blockage | Diagnostics of pressure in the system |
| The sound of escaping gas is heard | Mechanical damage | Urgently turn off and ventilate |
It is impossible to independently repair the leak and fill the refrigerator with freon Indesit without special equipment. It is necessary to evacuate the system, find the place of depressurization and accurately dose the refrigerant. Attempts to add freon Without eliminating the cause of the leak, only a temporary effect will be achieved.
Wear of the sealing rubber and loss of tightness
A frequent, but easily removable reason for the continuous operation of the refrigerator Indesit is a loose door fit. The sealing rubber (cuff) dries out, cracks or deforms over time. Warm air enters the chamber through the resulting cracks, causing the temperature sensors to initiate a cooling cycle.
You can check the tightness using a simple test with a sheet of paper. Clamp the sheet with the door around the perimeter. If the paper is pulled out easily, without resistance, it means that the seal does not fit in this place. It is also worth inspecting the rubber for cracks, tears or dirt that interfere with tight contact.
If the seal is simply dirty, it is enough to wash it with warm water and soap. In case of deformation, you can try to restore the shape using a hairdryer (gently heating the rubber) or boiling water. However, if the rubber has lost its elasticity and crumbles, it will need replacement of the seal a new one.
⚠️ Attention: When ordering a new seal for Indesit be sure to indicate the exact model of the refrigerator. Seals of different series may differ in the geometry of the corners and method of fastening.
Faults of the compressor and start relay
The most expensive component in the refrigerator Indesit is the compressor. If it is worn out, its performance decreases. The motor may hum, creating the appearance of work, but not create the necessary pressure in the system. As a result, the desired temperature is not reached and the refrigerator does not turn off.
It is also worth paying attention to starting relay. This small element is responsible for starting the engine. If the relay is faulty, the compressor may hum, click but not start, or run rough. Sometimes the relay “sticks” without opening the circuit, which leads to a continuous supply of voltage to the motor windings.
- 🔌 Symptoms: loud hum, clicks when trying to start, strong heating of the compressor housing.
- 📉 Efficiency: refrigerator it freezes weakly or only in one compartment.
- ⏳ Operating time: the motor does not go into rest mode for more than 12-20 hours.
It is better to diagnose the compressor by measuring the current consumption. If the current is lower than the rated current, there may be an interturn short circuit or mechanical failure. If the current is higher, the problem is electrical or jammed. In any case, replacing a compressor Indesit is a complex procedure that requires resoldering the tubes and refilling with freon.
The influence of external factors and improper operation
Sometimes the reason is that the refrigerator Indesit does not turn off, the problem lies not in the breakdown, but in the operating conditions. Placing the unit next to heat sources (radiators, stoves, direct sunlight) forces it to work in enhanced mode. Heat transfer through the walls of the case prevents the temperature inside from dropping to the set value.
It is also important to take into account the temperature in the room. If the refrigerator is placed in an unheated garage or on a balcony at a temperature below +10°C or above +30°C, its operation may not be correct. The oils in the compressor thicken in the cold, and in the heat the heat exchange of the condenser is disrupted.
Frequently opening the door or placing hot foods inside also disrupts the temperature balance. In this case, the refrigerator will work longer than usual, but after stabilizing the temperature it should turn off. Check that the door is tightly closed and that the unit is not overloaded, which interferes with air circulation.
FAQ: Frequently asked questions
How long should an Indesit refrigerator operate normally?
Under normal conditions, the operating cycle is approximately 15-20 minutes and 20-30 minutes rest. The work coefficient usually does not exceed 0.4-0.5. If the refrigerator works for 40 minutes and rests for 10, this is already a cause for concern.
Is it possible to operate the refrigerator if it does not turn off?
For a short time, it is possible, but this is an emergency mode. Long-term operation without stopping will lead to overheating of the compressor windings, oil burnout and eventual engine failure. It is better to eliminate the cause.
Why does the refrigerator not turn off for a long time after defrosting?
After complete defrosting, the refrigerator takes time (from 2 to 6 hours) to cool the entire volume of the chambers and freeze the food to the set temperature. During this period, continuous operation of the compressor Indesit is the norm.
Does the amount of food in the refrigerator affect its operating time?
Yes, a full refrigerator retains cold longer and is less likely to turn on, since food accumulates cold. An empty refrigerator heats up faster when the door is opened, which causes the compressor to turn on more often.
What to do if the refrigerator hums, but does not freeze?
This is a sign that the compressor is working, but the refrigerant is not circulating (clogged, leaking) or pressure is not being created. It is necessary to turn off the unit and call a technician to diagnose the system.
