The situation when Indesit refrigerator stops turning off is one of the most common and alarming for owners household appliances. Continuous operation of the compressor not only leads to a significant increase in energy bills, but also creates constant background noise in the room. Moreover, such operation at the limit of capabilities quickly wears out the engine, which can lead to expensive overhauls or complete replacement of the unit.
Understanding why the two-chamber model Indesit ignores stop commands requires a systematic approach to diagnostics. In some cases, the problem lies in simple user inattention or incorrect installation, but often we are talking about technical malfunctions of the cooling system. If the compressor operates without interruption for more than 24 hours, and the temperature in the chambers drops below normal or, conversely, does not reach the set values, this is a direct signal of a failure in the control circuit or a refrigerant leak.
In this article we We will analyze in detail the main causes of the malfunction, from simple operating errors to complex breakdowns requiring the intervention of a specialist. You will learn how to independently carry out initial diagnostics, which components to pay attention to first, and in which cases independent repairs can be dangerous for equipment.
⚠️ Attention: Prolonged operation of the compressor without rest cycles causes overheating of the motor windings. If you notice that the motor housing has become hot to the touch (more than 70-80 degrees), you must immediately disconnect the device from the network to avoid insulation melting or fire.
Primary diagnostics and external factors
Before suspecting a serious breakdown of internal components, it is necessary to exclude external factors that are often ignored by users. Ambient temperature plays a critical role in operation refrigeration equipment. If the unit is installed near heating devices, in direct sunlight or in a room where the temperature exceeds 30-35 degrees, the cooling system physically does not have enough power to achieve the specified parameters.
Under such conditions Indesit it will try to compensate for the heat inflow, working non-stop. It is also worth checking the tightness of the door. Loose hinges or dirty seals lead to constant suction of warm air from the room. Sensors record the temperature increase and give the command to the compressor not to stop.
Another common factor is the chamber being loaded with warm products. If you just returned from the store and put a pot of soup or a large amount of food at room temperature inside, the refrigerator will work hard until the entire volume has cooled down.
Faults in the defrost system and ice freezing
One of the key reasons why a two-chamber Indesit refrigerator works without interruption is a violation of the evaporator defrost cycle. In models with a system No Frost or drip defrosting, a “coat” of ice may form on the evaporator. If this ice does not thaw in time, it blocks the circulation of cold air, and the temperature sensor does not receive a signal that the desired degree has been reached.
Several components are responsible for the defrosting process: the evaporator heating element, the defrost sensor and the timer (or electronic control module). If any of these elements fails, ice builds up, heat exchange is disrupted, and the compressor is forced to work constantly, trying to “break through” the ice plug. Visually, this can manifest itself in the form of ice on the back wall of the freezer or in the bottom drawer.
Diagnosis of this problem requires partial disassembly of the freezer compartment. It is necessary to remove the plastic panel covering the evaporator and assess the amount of ice. If the evaporator is covered with a dense layer of frost, and the heating element does not heat up when the defrost mode is turned on, it means that the circuit is broken.
- ❄️ The defrosting heating element: it could burn out due to a power surge or natural wear, stopping heating the evaporator.
- 🌡️ Defrost sensor: could fail and not send a signal to turn on the heating element at the right time.
- ⏱️ Timer or module: the electronics could have “frozen” or the mechanical timer stopped switching modes.
How to check the heating element multimeter?
To check, you need to disconnect the refrigerator from the network, get to the heating element and test it with the multimeter probes in resistance measurement mode. If the device shows one or infinity, the circuit is broken, the heating element is faulty and requires replacement. Normal resistance is usually from 200 to 600 Ohms.
Problems with the thermostat and temperature sensors
The thermostat (thermostat) is the “brain” that decides to turn the compressor on and off. Older models Indesit use mechanical thermostats with a capillary tube, while new ones use electronic sensors. If the thermostat is “stuck” in the “on” position or its contacts have oxidized and closed, the compressor will receive current constantly, regardless of the actual temperature inside the chambers.
In models with electronic control, air sensors are responsible for monitoring the temperature. If such a sensor fails and transmits underestimated readings to the control module (for example, it reports that it is +10°C in the chamber, although in fact it is already -5°C), the refrigerator will work without stopping. Often, a breakdown of the sensor is accompanied by an error on the display, but not always.
Replacing the thermostat in mechanical models is a relatively simple procedure. It is necessary to find its location (often in a lampshade or on a wall), disconnect the wires and capillary tube, then install a new similar element. It is important to correctly set the temperature range after installation.
⚠️ Attention: When replacing a mechanical thermostat, make sure that the capillary tube is not kinked or damaged. A freon leak from the thermostat tube will make it completely inoperable.

Refrigerant leak and compression problems
The most serious technical reason for continuous operation is freon leak or a decrease in compression engine. When the amount of refrigerant in the system decreases, the refrigerator does not have enough power to create the required cold. The compressor works hard, trying to compensate for the lack of substance, but the temperature in the chambers either does not drop at all or drops very slowly.
Symptoms of a leak are often hot side walls (in places where the perimeter defrost circuit is laid) or, conversely, the absence of a characteristic hiss when turned on. You may also notice swelling on the back wall of the freezer. In case of loss of compression (wear of the motor valves), the refrigerator will also hum around the clock, not reaching the target values.
Repair in this case requires calling a technician with equipment for evacuation of the system, filling with freon and soldering pipelines. It is impossible to eliminate a leak on your own without special tools and skills.
| Symptom | Probable cause | Necessary actions |
|---|---|---|
| Compressor is hot, no cold | Leak freon | Finding the leak, soldering, refilling |
| There is a buzzing sound, there is little cold | Compression drop | Replacing the compressor |
| Ice on evaporator | Faulty defrost | Replacement of heating element or sensor |
| Refrigerator does not turn off at all | Thermostat is faulty | Replacement thermostat |
Features of operation in winter
Owners in winter Indesit may be faced with a paradoxical situation: the refrigerator runs non-stop, although it seems cool in the apartment. This is often associated with installing the refrigerator on an unheated balcony or near a window. If the ambient temperature drops below +10...+15°C, the oil in the compressor thickens and the pressure in the circuit drops.
Under such conditions, the refrigerator may not turn on at all or, conversely, may not work correctly. However, if the room is cold, but heat inflows are large (for example, the door is often opened), the equipment will work longer than usual. It is also worth remembering that some models are not intended for operation at temperatures below +10°C.
⚠️ Attention: Technical specifications and operating conditions may vary depending on the specific model and year of manufacture. Before installing the refrigerator in an unheated room, be sure to check the manufacturer’s official instructions (section “Climate Class”).
If you notice that the refrigerator has begun to behave strangely in winter, try moving it to a warmer place. Sometimes this solves the problem without replacing parts. Also check if the ventilation holes are clogged with dust, which is especially important after the summer season.
When you need to call a technician
There are a number of situations when self-repair is not only ineffective, but also dangerous. If you have checked the thermostat, made sure that the seal is intact and there is no ice on the evaporator, and the refrigerator Indesit continues to work without stopping, most likely the problem is hidden in the sealed circuit or electronics.
Intervention in the refrigerant circulation system requires a license and special equipment. Incorrect refilling with freon can lead to immediate failure of the compressor. Also, complex cases with an electronic control module require professional diagnostics with an oscilloscope.
Do not ignore the problem. A compressor that runs continuously is a ticking time bomb. Calling a specialist in a timely manner will help preserve equipment and avoid damage to products that may deteriorate if the unit suddenly breaks down.
- 🛠️ The smell of burnt insulation: requires immediate shutdown and calling an electrician.
- 💧 Oily stains: under the refrigerator indicates a leak of freon along with oil.
- 🔊 Knock and rumble: when the compressor is running, they indicate mechanical destruction of the components.
Is it possible to operate the refrigerator if it does not turn off, but keeps the cold?
Short-term operation is possible, but this is an emergency mode. The compressor is not designed to operate 24/7 without rest cycles. This will lead to overheating of the oil, loss of lubricating properties and eventual jamming of the piston group. The risk of fire and complete breakdown increases every hour.
Why does the new Indesit refrigerator not turn off for a long time after the first turn on?
When first started or after a long defrosting, the refrigerator takes time (from 2 to 12 hours) to reach operating mode. At this time, it can work without stopping, cooling the empty volume and the walls of the chambers. It is normal if after 12 hours it starts to turn on and off cyclically.
Does the amount of food in the refrigerator affect the operating time?
Yes, a full chamber keeps the cold longer and the compressor turns on less often. An empty refrigerator loses temperature faster when the door is opened, which forces the unit to work more often and longer. However, if the refrigerator is filled to capacity so that air circulation is disrupted, this will also lead to incorrect operation.
What to do if the refrigerator does not turn off after defrosting?
After defrosting, give the equipment 2-4 hours to stabilize the temperature. If the cycles have not returned to normal during this time, check to see if the evaporator is completely dry. Residual moisture could freeze and block the sensor. Also make sure that the thermostat was not accidentally dislodged or damaged during cleaning.
