The situation when your Indesit refrigerator suddenly stops starting always takes you by surprise. Silence in the kitchen instead of the usual hum of the motor, lack of light inside the chamber and, as a result, the risk of food spoilage are only the first symptoms of the problem that many owners of this equipment face. It is important to remain calm and not panic, since in most cases the reason lies in trivial things that can be fixed without calling a technician.
Before looking for complex breakdowns, it is necessary to carry out an initial diagnosis of the electrical network and external power supply. Users often forget that the equipment could turn off due to an accidental power surge or problems with the socket. Indesit models, like any other modern equipment, are equipped with protection systems that block startup when the electricity is unstable.
In this article we will analyze in detail all the possible reasons why the compressor does not start, and offer a step-by-step algorithm of actions. You will learn how to distinguish a burnt relay from an engine malfunction, and understand in which cases self-repair is impossible. Failure to start within 24 hours after defrosting may indicate a freon leak, which requires immediate specialist intervention.
Primary diagnostics: checking the power supply and socket
The very first and obvious reason why the refrigerator does not turn onis the lack of electric current. It would seem that this is elementary, but statistics show that in 30% of cases the problem lies precisely here. Check whether the plug is firmly inserted into the socket, and make sure that there is light in the room itself.
Sometimes the problem lies not in the unit itself, but in the wiring. If you connected the device through an extension cord or surge protector, try to exclude them from the circuit. Indesit refrigerators consume significant current at the time of startup, and old extension cords may not withstand peak loads, opening the contact.
- 🔌 Check for voltage in the outlet using another device, for example, hair dryer or lamp.
- 🔌 Inspect the power cord plug for melting, blackening or mechanical damage.
- 🔌 Make sure that the surge protector (if used) is turned on and its fuse has not blown.
If the socket is working, but the equipment is still silent, it is worth inspecting the power cord itself. It should not be twisted, pinched by furniture or have visible breaks in the insulation. An internal break in the wire core is a common reason why Indesit refrigerator does not start, although the indicators on the panel may light dimly or blink.
⚠️ Attention: Never try to repair the power cord with twisting and electrical tape. This creates a risk of short circuit and fire. The damaged cable must be replaced entirely.
The influence of power surges and protective mechanisms
Modern ones Indesit refrigerators are sensitive to the quality of electricity in the network. If your home experiences frequent power surges, it could trip internal protections or damage electronics. At the moment of switching on, the motor consumes a current several times higher than the operating one, and any anomalies in the network are critical.
If you notice that after being connected to the network, the device emits a quiet hum, but after a few seconds there is a click and the motor stalls, this is the work of a thermal protection relay. It shuts down the engine to prevent it from burning out due to overload. Repeated attempts to start in this mode only aggravate the situation.
How does thermal protection work?
The thermal relay is a bimetallic plate that is heated by the motor current. When the permissible temperature or current is exceeded, the plate bends and opens the circuit. To restore functionality, it needs time to cool down (usually 10-20 minutes).
To diagnose this problem, you can use a multimeter by measuring the voltage in the network. It must be within 220V ± 10%. If the indicators are outside these limits, starting the refrigerator may be blocked by the control module.
- ⚡ Use a voltage stabilizer to protect equipment in homes with an unstable power supply.
- ⚡ Let the device stand unplugged from the network for at least 30-40 minutes for the thermostat to cool down.
- ⚡ Check whether powerful consumers (welding, powerful heaters) are plugged into the same outlet.
It is important to understand that if the voltage surge was strong, the electronic control module could be damaged. In this case, Indesit refrigerator may not respond at all to turning on or display an error on the display.
Faults in the start relay and thermostat
If the electricity is okay, but the refrigerator does not start, the likely culprit is the compressor start relay. This small device is responsible for providing the impulse that starts the engine. Models Indesit often use posistor-type relays, which over time lose their properties or burn out.
You can determine a relay malfunction by the characteristic sound. If you hear a click, then a humming sound from the motor, and then a click and shut off again, the relay cannot start the engine. Also, the relay may be completely dead, and then no sounds from the engine compartment will be heard at all.
☑️ Diagnostics of the starting relay
The second important element is the thermostat (or temperature sensor in models with No Frost). If it is faulty and does not signal the need for cooling, the compressor will not receive a start command. In older models with mechanical control, thermostat failure is one of the most common reasons why Indesit refrigerator stopped turning on.
| Symptom | Probable cause | Characteristic sound | Actions |
|---|---|---|---|
| Silence, no reaction | Open thermostat circuit | Absent | Close thermostat contacts |
| Click, humming, shutdown | Faulty starting relay | Humming for 3-5 seconds, then clicking | Replacing the relay |
| Frequent clicks | Problems with compressor | Series of clicks | Diagnostics of windings |
| The lamp is on, but there is no cold | Freon leakage | The motor may be silent or buzz | Call a technician |
⚠️ Attention: Replacing the start relay requires precise selection of the model for a specific compressor. Installing an unsuitable relay can lead to burnout of the motor windings.
Problems with the compressor: wedge or combustion
The most serious and expensive problem is a malfunction of itself compressor. If the motor is mechanically jammed or an inter-turn short circuit has occurred in the windings, it will not be possible to start it using conventional methods. In such cases Indesit refrigerator it may try to start, make a heavy buzzing sound and immediately shut down due to protection.
You can check the condition of the compressor by measuring the resistance of its windings using a multimeter. Normal resistance values should be in a certain range (usually from 10 to 30 Ohms for the working winding and slightly higher for the starting winding). If the device shows an open circuit (infinity) or a short circuit (close to zero), the engine is faulty.
Another sign of a dying engine is strong heating of the housing in the lower part. If, after several attempts to turn on, the bottom of the compressor becomes hot, but cold does not appear in the chambers, most likely the resource of the unit has been exhausted. In this situation starting the refrigerator is impossible without replacing the unit.
It is worth noting that replacing a compressor is a complex process that requires evacuation of the system and charging of refrigerant. It is almost impossible to carry out this operation on your own without special equipment and skills.
Refrigerant leak and system blockage
Sometimes the engine is working, the relay and thermostat are working, but the refrigerator does not start or running in vain due to the lack of freon. If there is a leak (of refrigerant), the pressure in the system drops, and the sensors can block the compressor, or it works, but does not create cold. In some models Indesit at critically low pressure, starting does not occur at all.
It is difficult to determine a leak visually, since the gas is colorless and odorless. However, indirect signs may include swelling of the rear wall inside the refrigerator compartment or the presence of oily stains around the pipes in the engine compartment. If you notice such symptoms, you should not hesitate.
- ❄️ Blistering of the rear metal wall inside the refrigerator is a sign of moisture freezing due to a leak.
- ❄️ A hot condenser (grid at the back) with the motor running indicates gas circulation, a cold one indicates its absence.
- ❄️ Oil stains under the refrigerator or on the compressor tubes are a direct sign of depressurization.
Clogged capillary tube is another reason why the system does not work. An ice plug or a blockage from oil wear may form in it. In this case, the compressor may hum, trying to push freon, but there will be no circulation.
⚠️ Attempts to pierce the tubes yourself or add freon “by eye” will lead to final damage to the refrigerator. The system is sealed and requires professional maintenance.
Malfunctions of the electronic control module
In modern models Indesit with the No Frost system and display, the electronic control module is responsible for all processes. If the board burns out or fails, it stops supplying voltage to the compressor. This can happen due to a power surge, moisture or manufacturing defects.
Symptoms of a module malfunction may be: random blinking of indicators, lack of response to buttons, or, conversely, constant operation of the fans when the compressor is turned off. In some cases Indesit refrigerator it may emit an error sound.
If you notice traces of burning, soot or swollen capacitors on the control board, DIY repairs are only possible if you have soldering and circuit design skills. Most often, the module requires replacement or professional restoration at a service center.
Sometimes the problem is solved by simply rebooting the “brains” of the refrigerator. To do this, you need to completely disconnect the device from the network for 15-20 minutes, and then turn it on again. If this does not help, and the refrigerator does not startthe reason is deeper.
Is it possible to change the module yourself?
Theoretically, yes, if you find exactly the same board model. However, it is often necessary to configure parameters for a specific compressor and sensors, which is difficult to do without a service remote control.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator hum, but does not start?
A hum when it does not start most often indicates that the compressor is trying to start, but the starting the relay cannot start it, or the motor is seized. This may also be a sign of low voltage in the network.
How long should the refrigerator cool down before turning it on again?
After a disconnection or power surge, it is recommended to wait at least 30-40 minutes. This is necessary to equalize the pressure in the system and cool down the thermal compressor protection relay.
Is it possible to operate a refrigerator if it turns off periodically?
No, constant switching on and off (clocking) is harmful to the compressor and can lead to its rapid failure. It is necessary to find and eliminate the cause of unstable operation.
What to do if the refrigerator does not turn on after defrosting?
Make sure that the moisture inside the chambers is completely dry, especially in the area of the sensors. Check to see if water has come into contact with the electrical contacts. Let the appliance stand unplugged for a few more hours.
