How to Fix / Troubleshooting
Safety: Unplug the microwave before any inspection.
User-level checks:
- Verify that the wall outlet has power by testing with another appliance.
- Check that the plug is fully inserted and the cord is not visibly damaged.
Technician-level:
- Remove the outer cabinet and locate the internal fuse; test it with a multimeter and replace only with the exact same type and rating if blown.
- If the fuse blows again immediately, locate and repair the underlying short (e.g., mains filter, transformer, capacitor).
- Check any thermal fuses on the cavity or transformer for continuity.
Never bypass fuses or thermal cut-outs; they are critical safety devices.
