Here is the photo I spoke of.

JWWebster:
That 20 amp barrel fuse(gray in behind the small black disc) is what kills power to everything and that round black thing in front is a cavity limit, it protects the electronics by shutting down before the heat gets too bad. Before you change that fuse check your magnetron. If it has continuity from either of the 2 terminals to the metal frame then you needs ta replace the mag or the fuse will continue to blow. Also if the capacitor or diode is shorted that fuse will blow.
