How to Fix / Troubleshooting
Safety first: Unplug the microwave before any inspection. Do not open the cabinet unless you are trained.
User checks:
- Verify outlet: Plug another appliance (like a lamp) into the same outlet to confirm it has power.
- Check circuit breaker: Ensure the household breaker or fuse for that circuit has not tripped.
- Inspect power cord: Look for visible damage, cuts, or burn marks on the Hisense microwave's power cord. If damaged, do not use the unit.
Service recommendation:
- If the outlet is good and the cord appears intact, an internal line fuse or control board may have failed.
- Contact a technician to safely open the unit, test the fuse, and diagnose the power supply circuit.
