How do I fix an F32 (Fan Fault) code for a 9000X Series drive?

The F32 fault will only occur in FR8 or higher drives. There are 2 different types of fans, AC and DC. The more recent drives have DC fans and the previous models had AC fans. You can interchange the AC and DC fans but when you do so you have to change all of the fans and fan drivers in the drive. This means if you have a FR10 drive which has 2 main fans you need to change both fans and fan drivers. The DC fans are roughly 40% more efficient than the AC fans which is the reason for the change.
