A fan motor control device is provided in which in a situation where a control unit (10) cannot obtain a rotation request (LO request) at a first rotation speed and it becomes control based on a rotation request (HI request) at a second rotation speed from an OFF request, a lock current threshold value is changed from a first threshold value (first level) to a second threshold value (second level) and after a predetermined time has passed after a second drive signal based on the HI request is outputted, the lock current threshold value is returned from the second threshold value (second level) to the first threshold value (first level). |
