Abstract
A mode detector for microwave oven magnetrons is disclosed including means for sensing interruption of anode current and providing a discrete indication thereof. An alternative embodiment discloses means to count the number of such interruptions. A method of detecting incipient failure of the magnetron is disclosed wherein the discrete output of a mode detector is observed and a determination is made that an incipient failure exists when the mode detector output frequency exceeds a predetermined limit.
