Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the microwave before any inspection. Do not open the cabinet to access internal fuses; they are not user-serviceable.
- Check outlet: Plug a different appliance (like a lamp) into the same outlet to confirm it has power. If not, reset the home circuit breaker or replace the fuse.
- Inspect power cord and plug: Look for visible damage, burns, or kinks. If damaged, do not use the microwave.
- Try another outlet: Move the microwave to a known-good outlet on a different circuit and test.
If still dead: The internal line fuse, noise filter board, or main control board may have failed. These components are inside the cabinet and must be checked and replaced by a qualified Bosch technician.
