I found this thread researching my own issue. I am having a similar but different problem. On first hookup to hitch from storage the landing gear would only move a couple of inches then I would get the clicking with a steady red light on the control panel (Lippert 3.0). A few seconds would pass then green and go again. I noticed the left jack was going up at a much faster pace then the right which I have read is not too unusual.
Since I was only lifting the gear to put a wider jack pad under it I repeated the process with the gear going down, again, a few seconds of move, a few of wait, left one moving, right one catching up.
Is this the same diag, power issue?
