The invention belongs to the technical field of electronics, and particularly relates to a control method and system for restoring factory settings of an electric appliance. The control method for restoring factory settings of the electric appliance comprises the steps of obtaining use information of the electric appliance during last electrification when the electric appliance is powered on; according to the use information of the last power-on, judging whether the electrical appliance is used by a user or used by a test during the last power-on; if it is judged that the electrical applianceis in test use, enabling the electrical appliance to restore factory settings. Test use and user use of the electrical appliance are automatically distinguished, a station for restoring factory settings before packaging does not need to be added, and it is effectively avoided that some settings or functions are accidentally triggered easily when the electrical appliance is used for the first time.
