How to Fix / Troubleshooting
Safety: Unplug the microwave before any inspection. If you are not comfortable working with mains wiring, contact a technician.
Steps:
- 1. Check house power: Verify the circuit breaker or fuse for the microwave's outlet has not tripped. Reset if necessary.
- 2. Test outlet: Plug another appliance into the same outlet to confirm it has power.
- 3. Inspect power cord: Look for visible damage, burns, or cuts. Do not use the microwave if the cord is damaged.
- 4. Internal fuse (DIYers): Remove the outer cover and locate the line fuse near the power entry. Test with a multimeter. Replace only with the exact same rating and only after checking for shorts.
Resolution: If the fuse blows again or the control board shows no signs of life, replace the main control PCB or have a technician diagnose further.
