ABSTRACT OF THE DISCLOSURE A microwave oven comprises a digital control circuit for controlling microwave generation, and a multi-digit digital display unit for displaying a cooking condition. A determination system is associated with a door switch for developing a display control signal when a cook start switch is actuated before the oven door is tightly closed. In response to the display control signal, an alarm display, for example, "DOOR" appears on the multi-digit digital display unit. The microwave oven further comprises a food temperature sensor probe for sensing the temperatures of foods being prepared in the oven. The multi-digit digital display unit provides another alarm display, for example, "PRObE" if the cook start switch is actuated before the probe is plugged in for proper operation.
