Freezer shows F10 and may not cool correctly; temperature may drift high or low.

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty ambient NTC sensor (if fitted), Damaged sensor wiring near compressor compartment, Connector corrosion at PCB, Sensor dislodged from mounting point

How to Fix / Troubleshooting

Safety first: Disconnect from mains before working at the rear of the appliance.

Locate ambient sensor:

Some Indesit freezers use an ambient NTC sensor near the condenser or compressor area to adjust operation based on room temperature.
Look for a small probe or plastic-encased sensor attached to the rear metalwork or near the compressor.

Inspection and testing:

Check that the sensor is intact and not hanging loose or touching hot components directly.
Inspect the cable for cuts or crushed sections.
Measure resistance with a multimeter and compare with typical NTC values at room temperature.

Repair:

Replace a faulty ambient sensor with the correct Indesit NTC part.
Secure the sensor back in its original location, away from direct heat sources but in free air.
Ensure the connector at the PCB is clean and firmly seated.
