Abstract: A motor driven appliance in one aspect of embodiments of the present disclosure comprises a light source, a lighting unit, a motor, an operation unit, an operation detector, a reference signal output unit, a determination unit, and a control unit. The operation detector detects that the operation unit is operated, and outputs an operation detection signal that indicates that the operation unit is operated. The reference signal output unit outputs at least one reference signal that can be used as a reference for determining whether the detection by the operation detector is normal. The determination unit determines whether the operation unit is actually operated based on the operation detection signal and the at least one reference signal. The control unit controls operation of the lighting unit based on the determination made by the determination unit.
