Title: Microwave oven having a microwave detecting device

Abstract: A microwave detecting device outputs a first predetermined voltage in accordance with the presence/absence of microwave in a waveguide. A microcomputer inputs the first predetermined voltage, outputs a second predetermined voltage in accordance with the level of the first predetermined voltage, then detects the voltage of an input port of the first predetermined voltage by applying the second predetermined voltage to the input port of the first predetermined voltage, and displays the operational status of the microwave detecting section in accordance with the voltage detected from the input port. The microwave detecting section includes a diode sensor, which is connected between the waveguide and the input port of the microcomputer in a forward direction to output the first predetermined voltage in accordance with the presence/absence of the microwave in the waveguide. The microcomputer may further include a check button for applying a check signal to the microcomputer, and then the microcomputer outputs the second predetermined voltage in accordance with the inputted check signal.
