Is this a repeating cycle? If so its the control box.

I'm not totally sure but I think the underlying cause is that the relay is
stuck. Mechanical encouragement may unstick for a while.
The problem is that the fan start the APS responds but the relay does not
switch over to keep the fan running so the APS fails after a second or
two. Then the fan is powered again and so on....

Replacements are readily avilable from cetltd.com .
