Possible Causes

Faulty compressor inverter module, Wiring fault between PCB and inverter, Defective variable-speed compressor, Main PCB control signal failure

How to Fix / Troubleshooting

Safety first: Unplug the appliance. Compressor and inverter circuits carry dangerous voltages.

Step-by-step checks:

  • 1. Identify system type: Check if your Indesit model uses an inverter compressor (separate inverter box near compressor).
  • 2. Visual inspection: Inspect the inverter module for burn marks, cracked casing, or loose connectors.
  • 3. Check harness: Ensure all plugs between main PCB, inverter, and compressor are fully seated and undamaged.

When to call a technician: Testing inverter outputs and compressor windings requires specialist tools and knowledge. F11 on inverter systems is typically a professional sealed-system repair.
