Possible Causes

Blown household fuse or tripped breaker, Faulty power cord, Loose internal mains connection, Failed main PCB power supply

How to Fix / Troubleshooting

Safety first: Do not open mains wiring compartments unless you are competent with electrical safety.

  • Step 1 – Check outlet: Test the wall socket with another appliance. Reset any tripped breakers or replace blown fuses.
  • Step 2 – Inspect plug and cord: Look for damage to the SMEG refrigerator's plug and cable. Replace if damaged.
  • Step 3 – Try another outlet: Plug the fridge directly into a known-good outlet without extension leads.
  • Step 4 – Internal checks: If still dead, the internal mains filter or PCB power supply may have failed. This requires professional diagnosis and likely PCB replacement.
