You'll want to have a deep wall 7mm socket for this.</P>

The link is no longer good. Anyone have an updated link for swapping out the actuator?

Also, the fan will now at on sites when on 5 and then all of a sudden the speed increased dramatically. Later it will again bike slower. I changed out the control unit but it still does the same thing. Any ideas?
