To provide a control device for an electric apparatus useful for investigation of a failure cause and maintenance and inspection by reproducing a faulty event to know history or the like of the occurrence of the faulty event.
The electric apparatus is provided with a detecting means 6 for detecting the operating state of functional parts such as a blower 2, and information required for maintenance and inspection, and a control circuit 8 equipped with a microcomputer 7 for controlling the operation of the functional parts based on the information detected by the detecting means 6. The control circuit 8 stores the information detected by the detecting means 6, as temporally continuous data or time series data of discrete data close to a time-ticking small continuation, in a nonvolatile storage means 9 at all times and also stores time series data after the lapse of periodical operation time of the electric apparatus in the storage means 9 at all times, and the time series data stored in the storage means 9 can be read at the occurrence of a failure and in maintenance and inspection.
