[quote=tchism465;130189]I have disconnected the magnetron, still makes loud buzzing sound when running. I have changed the diode, still buzzing. Checked primary windings and 120V on HV transformer. 120V present when on. Primary windings read 1 ohm. It also looks like the secondary windings read about 115 ohms.
The magnetron when testing reads about .5 ohms to each other and no short to ground per terminal.

Does anyone have a clue?

Any help is appreciated.
