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.
