ABSTRACT:
A microwave oven includes a magnetron for performing a microwave cooking function, and a separate electric heater element for performing a grilling function. A single control knob on a control panel serves to activate the magnetron and heater element, as well as selecting an output power of the magnetron. By actuating that single knob a user can select cooking operations solely by microwaves only, or solely by the heating element, or by a combination of both. A separate knob on the control panel enables a cooking time to be selected.
