I took the turner out and removed the motor. I could not really find a catch in the mechanism until I rotated way too far. I rubbed some beeswax on all the rotating points of contact. I put it back together (went cat herding) and put it on the table and plugged it up. I’m watching to see where it is every hour at least until I go to bed. I don’t know how well the beeswax will work, but I know that La-Z-Boy uses beeswax on all of its recliners. Yes, I built chairs for a whopping 10 months in another life.
