ABSTRACT:
System and method for interrupting the delivery of microwave power to a microwave cavity when a door to the cavity is opened and an interlock switch fails to operate. A switch actuated by movement of the door applies an overload current to an overload protector in the filament circuit of the generator which supplies microwave power to the cavity, thereby interrupting the filament current and shutting down the generator.
