Is it ringing the gong or lighting the direction arrow?
“Never loose the door lock circuit”. Hmm. You’ll never see it open until it does...literally.
Have you ever found the car sitting with the doors open and out of service? Typical door lock trouble.
Clutch nicking the pick up rollers?
Check that machine allen head bolt on the linkage arm. If it’s loosened, the car door will drift open, or not close fully, but your limit and gate will stay up.
