Abstract
If a fan motor in a stopped state remains stopped even when it is powered on, restart processing of the fan motor is carried out by rotating the fan motor forward and backward. If the fan motor rotates as a result of the restart processing, an indication to prompt replacement of it is displayed. If the fan motor remains stopped without rotating, in contrast, it is determined to be defective, and an electronic apparatus is stopped.
