How to Fix / Troubleshooting
Safety first: Ensure the unit is unplugged before any inspection.
User-level checks:
- Verify the wall outlet has power by testing with another appliance.
- Check that the plug is fully inserted and the cord is not damaged or pinched.
- Check the household fuse or breaker for the circuit.
Next steps:
- If the outlet is good and the microwave remains dead, an internal fuse or power board has likely failed.
- Internal fuse replacement involves exposure to mains wiring and should be done by a technician.
