The situation when Indesit refrigerator stops turning on always takes you by surprise. You approach the unit, open the door, but it’s warm inside, the food begins to spoil, and the usual hum of the motor is missing. Often, panic forces users to immediately call a technician, but in most cases the problem lies in basic things that can be checked independently in a few minutes.
Before disassembling the back wall or looking for a service center number, you need to carry out an initial check. visual diagnostics. Lack of response to switching on may be caused by a banal power outage in the entire house or by a plug flying out of the socket. It is also worth listening: if you hear a quiet click, followed by a hum, lasting 5-10 seconds, and then again a click and silence, this indicates an attempt to start, which is blocked by protective systems.
In this article we will analyze in detail the main reasons for equipment failure Indesit to work. We will go from checking the socket to complex diagnostics of electronic control modules. Understanding how your refrigerator works will help you save time and money, as well as prevent more serious breakdowns in the future.
Checking the power supply system and network cable
The most obvious, but often ignored reason is the lack of voltage in the network. If Indesit refrigerator does not make any sounds and the indicators on the panel do not light up, first make sure that there is electricity in the house. Try plugging another electrical appliance into the same outlet. Sometimes the problem lies in oxidized contacts or burnt-out wiring inside the outlet itself.
Carefully inspect the power cord and plug. In models Indesit with no-frost, damage to the cable at the entry point into the case or at the plug itself is common due to frequent movements of equipment. If cracks are visible on the insulation and the plastic inside the plug is blackened, operating the device is strictly prohibited is a direct threat to fire safety.
⚠️ Attention: If you find a melted plug or smell a burning smell from the cable, do not try to simply replace the cord. Such damage often indicates a short circuit inside the refrigerator wiring, which could damage the compressor or the start relay.
It is also worth checking the integrity of the fuse if your model is equipped with an individually protected outlet. In old houses with unstable voltage, current surges could knock out plugs on the kitchen line. Make sure the circuit breaker in the panel is turned on.
Diagnostics of the starting relay and compressor
If the light in the chamber is on, but the motor is silent, or you hear characteristic clicks, but the start does not occur, most likely the problem lies in the start protection relay or itself compressor. The relay is responsible for supplying current to the motor windings. In refrigerators Indesit it is these components that often fail due to overloads or power surges.
To check the relay, it must be removed from the compressor. It is usually mounted on the side of the motor and held in place by a bracket or latches. Visually inspect the relay body: if traces of burning, melting are visible on the plastic, or burnt holes are felt, the part requires replacement. Inside the relay there is a coil and contacts that can stick or burn over time.
The process of replacing the relay does not require complex equipment, but requires compliance with safety precautions:
- 🔌 Be sure to unplug the refrigerator before removing any parts.
- 🧤 Work with dry gloves so as not to leave traces of grease on the new contacts.
- 🔨 Carefully remove the old relay so as not to damage the compressor tubes.
- 🔍 Make sure that the new relay matches the markings of the old one (they are not universal).
If replacing the relay did not help and the compressor still does not start or makes a loud noise hum and immediately turns off, perhaps the motor-compressor itself has jammed or one of its windings has burned out. In this case, professional diagnostics are required by measuring the resistance of the windings.
How to check the resistance of the windings?
To check, you need a multimeter in ohmmeter mode. Remove the relay and connect the probes to the compressor contacts. The resistance between the starting and running windings should be the sum of the resistances of each winding relative to the common contact. If the device shows infinity or zero, the winding is open or shorted.
Malfunctions of the thermostat and temperature sensors
The thermostat (thermostat) is a device that commands the compressor to turn on when the temperature in the chamber rises above the set one. If thermostat is faulty and its contacts are open, the compressor power circuit does not close and the refrigerator does not turn on, although the chamber may be warm.
In mechanical models Indesit the thermostat is often located inside the chamber or behind the control panel. You can check it by closing the contacts directly (using a jumper). If after closing the contacts the compressor starts, then the problem is in the thermostat. In modern models with electronic control, the role of a thermostat is performed temperature sensorswhich transmit data to the control module.
The main signs of a malfunction of the thermoregulatory system:
- ❄️ The compressor does not turn on at all, even when defrosted evaporator.
- 🌡️ The refrigerator works non-stop, without turning off (if the contacts are “stuck” in the closed state).
- 🔌 When you turn the regulator knob, you do not hear a characteristic click.
Replacing the thermostat in mechanical models is a quick procedure. In electronic systems, it may be necessary to replace the sensor itself, which is usually located in the evaporator or in the air duct.
Problems with the electronic control module
Modern refrigerators Indesit equipped with sophisticated electronics. Control module (board) analyzes sensor readings and controls the operation of the compressor, fans and defrost system. If the board is faulty, the compressor may not receive a signal to start, even if all other components are working.
Power surges in the network are a common cause of module failure. Fuses, tracks or control triacs on the board may burn out. Visually, this often manifests itself in blackening of the elements, swelling of the capacitors, or the appearance of burning. Also, error codes may light up on the display, for example, blinking indicators in a certain sequence.
⚠️ Attention: Repairing electronic modules requires special knowledge and equipment. If you do not have experience working with electronics, attempting to repair it yourself may result in complete failure of the board. In such cases, it is more rational to replace the module with a new one.
To diagnose the module, you need to remove the back cover (usually it is located at the top of the refrigerator) and inspect the board. If obvious signs of thermal stress are visible, the board should be replaced. Sometimes the problem is solved by a simple “reboot” - disconnecting the refrigerator from the network for 15-20 minutes.
Symptoms of a faulty starting capacitor
The starting capacitor helps the compressor gain the necessary speed at start. If its capacity has fallen or a breakdown has occurred, the motor will hum, trying to start, but the rotor will not rotate. After a few seconds, the thermal protection will operate and the compressor will turn off.
The capacitor is an inexpensive part, but its failure paralyzes the operation of the entire unit. You can check it with an ohmmeter: when connecting the probes, the arrow of the device should deviate and then slowly return back. If the arrow stands still or shows zero, the capacitor is faulty.
Comparative table of symptoms of various faults:
Faulty start relay or jammed compressor
| Symptom | Probable reason | Characteristic sound | Action |
|---|---|---|---|
| Silence, no light | No power, open circuit | Absent | Check socket and cord |
| Click, hum for 5 seconds, silence | Hum, click | Replace the relay, check the compressor | |
| Humms, but does not start | Starting capacitor | Monotonous hum | Measure the capacitance of the capacitor |
| The light is on, the motor is silent | Thermostat or module | Absent | Ring the thermostat |
External factors and operating conditions
Sometimes the reason why Indesit refrigerator does not turn on lies not in a breakdown, but in incorrect operating conditions. For example, if the temperature in the room where the equipment is located drops below +10°C (which is important for balconies or dachas in winter), the thermostat may not turn on, as it considers that the temperature is already quite low.
Ventilation also plays an important role. If the refrigerator is pushed tightly against the wall or built into a niche without gaps, the compressor may overheat. In this case, a thermal protection relay is triggered, which turns off the motor until it cools completely. On-off cycles become very short.
Installation recommendations:
- 📏 Leave a gap of at least 5-10 cm from the back wall to the wall of the room.
- ☀️ Do not install the refrigerator next to radiators or in direct sunlight rays.
- 🧹 Regularly clean the capacitor (black grille at the back) from dust and animal hair.
☑️ Diagnostics before calling a technician
When you need to call a professional masters
There are a number of situations when independent repairs are not only ineffective, but also dangerous. If you have checked all the electrical circuits, relays and thermostat, but Indesit refrigerator it still does not work, the problem probably lies in the sealed circuit or the compressor itself.
Alarming signs requiring specialist intervention:
Smell of refrigerant (freon). Although freon itself is often odorless, oil with a characteristic chemical aroma may leave the system along with it. If you smell a burning smell that does not disappear after airing, or the smell of oil, a leak has occurred.
Mechanical damage to the tubes. If, while cleaning or moving, you touch and damage the aluminum or copper evaporator tubes, the system will become depressurized. In this case, the compressor will run idle, trying to pump up pressure, but there will be no cold.
⚠️ Attention: Replacing the compressor yourself or searching for a freon leak requires a vacuum pump, a pressure gauge station and refrigerant supplies. In addition, working with refrigerants requires a license. An attempt to refuel "by eye" will lead to rapid breakdown of the new compressor.
A master is also needed if the compressor needs to be replaced. This process involves cutting the capillary tube, soldering in the new motor, evacuating the system, and charging the exact amount of freon. An error in the amount of refrigerant or the presence of moisture in the system will lead to equipment failure in the shortest possible time.
How long does a compressor last?
The average service life of a compressor in Indesit refrigerators is 10-15 years, provided there is a stable voltage in the network. Frequent power surges reduce this period by 2-3 times.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator hum, but does not cool?
If you hear a hum, but there is no cold, there may be a freon leak or a clogged capillary tube. Also, the compressor may work, but not create compression due to internal valve failure. Diagnostics by a specialist is required.
Is it possible to turn on the refrigerator immediately after defrosting?
Yes, modern refrigerators Indesit can be turned on immediately after defrosting and wiping dry. However, if you washed the floor underneath and moved the unit, it is recommended to wait 2-4 hours before turning on so that the oil in the compressor flows into the crankcase.
What does a flashing alarm indicator on the panel mean?
A flashing indicator (often a red triangle or exclamation mark) indicates that the temperature in the chamber is rising above normal. This may be a consequence of opening the door for a long time, loading warm food, or a malfunction of the cooling system.
How to reset the error on an Indesit refrigerator?
To reset the error, try unplugging the refrigerator for 15-20 minutes. If the error is caused by a temporary electronic failure, it will disappear. If the problem is technical (for example, the sensor is faulty), the error will return after switching on.
Why does the refrigerator not turn on itself after the lights are turned off?
In some models with electronic control, after power is restored, a manual restart (manual start) is required or just time for self-diagnosis of the system. Also check if the temperature settings have gone wrong.
