How do I fix an F65 Replace Fan Faultcode for a DG1 drive?

The replace fan fault is an indication that the fan life is less than 2 months, the drive monitors this based off the power on time of the drive so with if the fan is not set run all the time the fan life can be extended. When this fault occurs it is possible to reset the fault and the fan run time counter will reset no matter it being a new or old fan. This is just an indication that the fan may fail shortly and a replacement may be good to have ready.
