ABSTRACT:
A microwave oven system in which a magnetron supplies microwave energy to a microwave oven through an isolator structure comprising a three-port circulator having a microwave energy absorbing load coupled to the third port, with the temperature of said load being sensed by a first switch actuated at a first temperature level to maintain a flow of air across the load continuously between operating cycles of the oven and by a second thermally operated switch actuated at a higher temperature to disable the power supply for the magnetron.
