ABSTRACT:
A control system for a microwave oven includes a magnetron power circuit, an electronic controller, and input control circuitry. The control system is adapted to be connected to a source of electrical power, typically an AC line supply. The line supply may be converted to DC for powering the electronic controller, however, the input control circuitry is structured to prevent connection of the power supply to the electronic controller until an intentional manual action occurs. This prevents the electronic controller from responding to noise or the like to become unintentionally powered and thus possibly operate in an undesired state. The input control circuitry includes switches associated with data input keys for temporarily connecting power to the controller when actuated. Such actuation of a data key enables the system to be powered-up and also to enter data.
