Hi all,
I recently replaced the magnetron on a microwave. It was a Panasonic inverter type. Some suggest it could be the inverter or the magnetron. I decided to go buy a new magnetron from Prime Electronics and replaced it. It worked. The old magnetron have some grease (cooking) on it cooling fins(??) but apart from that I couldn't see any problems on the outside. I am just curious what could break in a magnetron. The microwave was about 4-5 years old.
Thank you Anthony
