The situation when your Indesit stops showing signs of life always takes you by surprise. The internal space begins to heat up, food spoils, and panic increases with every minute of equipment downtime. However, before calling a technician, it is worth carrying out an initial diagnosis, since in many cases the problem lies in trivial things that can be fixed on your own.
Modern refrigerators Indesit are complex electromechanical devices, where the failure of one element can paralyze the operation of the entire system. Not only cold may be absent, but also light and the characteristic hum of the engine. Understanding why the Indesit refrigerator does not turn onwill help you save time and money by avoiding false service calls.
In this article we will analyze in detail the troubleshooting algorithm, starting from checking the power supply and ending with complex diagnostics of the compressor. You will learn how to distinguish a breakdown that requires replacement of parts from a temporary failure in the electrical network.
Primary diagnosis: checking for the presence of voltage
The most obvious, but often ignored reason - lack of electricity in the outlet. If the refrigerator Indesit is silent, the indicator does not light up and the motor does not start, the first thing you need to check is whether current is flowing to the device. Sometimes the problem lies not in the equipment, but in the wiring of the apartment or the condition of the power cord.
Visually inspect the plug and the cord itself for melts, kinks or traces of rodents. If everything looks fine on the outside, try connecting another device to the same outlet, for example, a hair dryer or lamp. This will allow you to instantly understand whether there is voltage in the network. It is also worth checking the circuit breakers in the electrical panel - perhaps there was a power surge and the plugs were knocked out.
The condition of the outlet itself deserves special attention. Over time, the contacts inside it can weaken or oxidize, resulting in poor contact. If you use an extension cord or surge protector, try connecting the refrigerator directly to the wall, as these devices can also fail.
☑️ Initial electrical check
Malfunctions of the thermostat and temperature sensors
If there is electricity in the house, but the refrigerator Indesit still does not turns on, the next probable cause is failure of thermostat (thermostat). This element is responsible for maintaining the set temperature inside the chambers. When it breaks, the compressor power circuit opens and the motor does not receive a signal to start.
In models with mechanical control, the thermostat is a (knob) that you turn to change the mode. Inside it is a capillary tube that is sensitive to temperature changes. If this tube bursts or leaks, the gas escapes and the contacts remain open forever. In electronic models, this function is responsible sensors, which can also fail.
⚠️ Attention: When diagnosing a thermostat, the “short circuit” method is often used. If, when connecting the wires bypassing the thermostat, the refrigerator starts, it means that the regulator is faulty and requires replacement.
Symptoms of a thermostat failure can be not only complete silence of the unit, but also its continuous operation without shutting down. However, in the context of the question “why it doesn’t turn on,” we are interested in the circuit break. Replacing this element requires disassembling the top of the refrigerator or removing the internal panel, depending on the design. Indesit.
How to check the thermostat with a multimeter?
To check, remove the thermostat and immerse its sensitive tube in cold water (about 0 degrees). Test the contacts with a multimeter: if the circuit does not close, the device is faulty. At room temperature, the contacts should be closed.
Problems with the start-up relay and the compressor
The heart of the refrigerator is compressor, and the start-up relay is its “starter”. It is these components that most often become the culprits that the refrigerator Indesit does not turn on, although the light in the chamber is on. The relay sends a powerful impulse to the motor windings to start it, and then opens the starting circuit.
If the relay is burned out or the contacts are stuck, the compressor will not be able to start. You may hear a quiet click followed by nothing happening, or short attempts to start followed by a click and silence. In some cases, the relay may be serviceable, but motor-compressor itself has an interturn short circuit or jamming.
Diagnostics of these components requires certain skills. You need to remove the back cover at the bottom of the refrigerator where the compressor is located. Visually inspect the relay: if you can see traces of burning on the plastic or smell burning plastic, the part definitely needs to be replaced. You can also gently shake the relay - if you hear the ringing of a broken part inside, it is faulty.
Failure in the electronic control module
In modern models Indesit with a system No Frost and an electronic display, the electronic control module is responsible for turning the compressor on and off. This is the “brain” of the refrigerator, which collects data from all sensors and decides to start the cooling cycle. Failures in its operation can lead to complete blocking of startup.
The reasons for module failure can be different: power surges in the network, moisture ingress, manufacturing defects or natural wear and tear of electronic components. If errors appear on the display or, conversely, it goes out, although there is light in the camera, the problem may lie in the control board.
Often the module fails due to problems with the wiring or oxidation of the contacts. Before replacing an expensive board, it is worth checking the integrity of the cables going to it. Repairing the module is possible, but requires professional equipment and knowledge in the field of microelectronics.
Mechanical damage and wiring
Do not discount trivial mechanical damage damage. The refrigerator Indesit during operation or transportation may have received a shock that damaged the internal connections. Frayed wires, oxidized contacts or loose terminals are common culprits of lack of power.
Particular attention should be paid to the wiring running from the door to the body. Where the cable bends, the wires often break due to the constant opening and closing of the door. This may cause the door sensor or temperature sensor to stop transmitting a signal, and the refrigerator will not turn on.
It is also worth checking the integrity of the grounding. Although the refrigerator will operate without it, the lack of grounding can lead to the accumulation of static electricity, which in rare cases affects the operation of sensitive electronics.
| Symptom | Probable cause | Required actions |
|---|---|---|
| No light and sound | No voltage in the socket | Check the machine, cord, socket |
| There is light, silence | The thermostat is faulty | Replacing the thermostat |
| Clicks, but does not start | Start relay or compressor | Diagnostics of relays and motor windings |
| Errors on the display | Electronics failure or sensors | Checking the module and cables |
The influence of defrosting and climatic conditions
Sometimes the answer to the question why the refrigerator does not turn on lies in improper operation. If you have just defrosted Indesit and turned it on too early, the compressor may not start due to residual moisture in the system or water hammer. It is also important to observe the time interval between turning off and turning on again.
The climate class of the refrigerator also plays a role. If a device designed for moderate climates is operated in an unheated room at temperatures below +10°C, the oil in the compressor may thicken and the motor will not be able to turn over. In such cases, the equipment may not respond at all to being turned on.
⚠️ Attention: After defrosting or transporting in a horizontal position, turn on the refrigerator no earlier than 4-8 hours later. This is necessary for the oil to drain into the compressor crankcase.
In addition, check the position of the temperature regulator. If it is accidentally turned to the "0" or "Off" position, the refrigerator will not work. This is an elementary but common mistake, especially if there are small children or animals in the house.
Is it possible to turn on a refrigerator on the balcony in winter?
Only if its climate class allows it (for example, SN or ST). Conventional models at temperatures below +10°C may not start or quickly fail due to condensation and thick oil.
Frequently asked questions (FAQ)
Why does the Indesit refrigerator hum but does not turn on?
If you hear a hum, but the cold does not come, it may indicate an attempt to start a compressor that lacks power (problem with the start relay) or is stuck. The transformer in electronic models can also hum when the board is faulty.
How much does it cost to replace a thermostat in an Indesit refrigerator?
The cost consists of the price of the part itself and the work of the technician. Thermostats for Indesit belong to the middle price segment. It is better to check the exact amount at service centers in your city, since prices depend on the model and region.
Is it possible to repair a compressor yourself?
Replacing a compressor requires special equipment: a burner, a vacuum pump and skills in working with refrigerant. Doing this on your own is extremely difficult and dangerous. It is better to replace the entire assembly by a professional.
What to do if after a power surge the refrigerator stops working?
First of all, check the fuses (if any) and the condition of the power cord. Often during surges the starting relay or electronic module burns out. Try unplugging the appliance from the outlet for 15-20 minutes to reboot the electronics, then turn it on again.
