Possible Causes

Blown internal fuse on PCB, Failed power supply section of main board, Loose mains connector, Damaged power cord

How to Fix / Troubleshooting

Safety: Unplug the refrigerator before any inspection. Mains voltage is present inside.

Basic user checks:

  • Verify outlet: Test the wall socket with another appliance to confirm power is available.
  • Check power cord: Inspect for cuts, burns, or kinks. Do not use the appliance if the cord is damaged.
  • Reset RCD/fuse: Ensure your household circuit breaker or fuse has not tripped.
  • Internal fuse: Some Zanussi PCBs have a replaceable fuse, but accessing it requires removing covers and exposes live parts. This should be done only by a qualified technician.

Professional repair: If external power is good but the unit is dead, the main PCB or internal wiring likely needs professional diagnosis and replacement.
