How to Fix / Troubleshooting

Safety: Unplug the microwave before any inspection.

Basic checks:

  • Verify the wall outlet has power by testing with another appliance.
  • Check the household circuit breaker or fuse for the microwave circuit.
  • Inspect the power cord for visible damage.

Internal fuse (qualified):

  • Remove the outer cover and locate the main line fuse near the power entry.
  • If the fuse is blown, investigate for short circuits (door switches, HV components) before replacing.
  • Replace only with the exact same rating and type specified by Fagor.

If the new fuse blows immediately, stop and have a technician diagnose the underlying fault.
