ABSTRACT:
A control apparatus for a heating appliance, such as a microwave oven, uses a microcomputer as its control means. A power switch for supplying power to heating means, such as a magnetron, is controlled by two switching devices, which switching devices are controlled by the microcomputer. When the user actuates a start switch, the first switching device is actuated by a control signal from the microcomputer, and thereafter, the second switching device is actuated to activate the power switch if the heating appliance is in proper operating condition. The microcomputer stops the entire heating operation whenever the heating means is not operating properly, by sensing an improper condition of the second switching device.
