Unscrewed the cover of the microwave replaced the blown fuse with the new fuse, plugged in the microwave and tested all functions and everything worked fine. Thx for quick delivery.
Found instruction on internet, 1. Remove anit-tampering screws with punch and hammer 2. Remove the rest of the screws 3. Removed cover 4. Remove burned out bulb and installed new one 5. INstalled cover 6. Installed screws including the anti tampering onces 7. Op tested unit. Wife is happy.
Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.
