Microwave stopped heating. Tech-Sheet inside cover. Diode reads open in both directions on diode setting but reads open one way and reads 16.3 M ohms in the flow direction (tested with Fluke 77IV meter). Megnetron reads 0.2 ohms across filament terminals , but reads 17 ohms from
filament to chassis. The tech-sheet reads it should be infinite.
What do I do now?

ANSWER Hello Paul. Based on the test you provided, you need to replace the diode and the magnetron 8184652 in the unit.
