AMANA MICROHOOD -No heat with loud buzzing

The control panel seems to be working properly. No heat and the microwave is making a loud humming noise. We do a lot of microwave popcorn and from what I have read thus far… it seems to be a magnetron problem for most people. Should I be ordering any other parts in conjunction with this and save myself the time of having to take it apart twice. Thanks, I appreciate any suggestions.

Just a mechanically minded housewife that misses her microwave :slight_smile:
