headspace autosampler 7697A growling noise and waiting status in middle of run

I have the headspace autosampler 7697A attached to a GC 7890A.  I have two issues.  the first is a growling noise when the gripper moves in the downward motion. Not the entire way just the middle third.  I am guessing a service call will need to be made for this one as some mechanical or electrical part is about to fail.  The second is that the autosampler is stopping several vials into the first tray on the second round.  There is no error.  The status reads "sequence waiting for tray".  The tray lights are green, and like I said it already ran several 4-9 vials.  We can park and unpark to clear it and continue the run, but this is not helpful when running over night.  Any one see this issue?  easy fix?  or service call?
