Abstract

A process for detecting the operation status of an IC heat fan, which mainly comprises the following steps: (1) taking the armature current signal of a fan motor; (2) amplifying the differential signal of the current; (3) detecting a pulse signal; (4) determining whether the pulse signal of the step (3) is abnormal.
