There’s the arm with a roller on the end of it (don’t know the terminology). It hits a ramp when the door closes causing the closing vane on the clutch to retract. When the doors are closed is it on the bottom flat part of the ramp? If it’s still on the angled part that might be your problem. I e seen it multiple times before causing your issue. When the doors sits idle and looses holding voltage to doors that little bit of horizontal pressure will push the doors off the dcl. The doors will reopen and close again and then everything repeats eventually faulting out. Readjust the height and horizontal position of the ramp so the roller is on the flat bottom so all pressure is downward.
