Possible Causes
Blown internal line fuse, Faulty power cord, Failed line filter board, Open thermal fuse on cavity or magnetron
How to Fix / Troubleshooting
Safety: Unplug the microwave before inspection. Internal fuses are not user-serviceable in many regions; opening the cabinet may void warranties and expose you to high voltage.
Steps:
- 1. Check outlet and breaker: Test the outlet with another appliance. Reset any tripped breakers.
- 2. Inspect power cord: Look for cuts, burns, or loose plug blades. If damaged, have the cord or filter assembly replaced.
- 3. Internal fuses and thermal cutouts: A technician should open the unit, test the line fuse and thermal fuses on the cavity and magnetron, and replace any open devices after identifying the cause.
