Hi Guys.
Any pointers on this problem? Lift intermittently traps occupants in the car. Then will run ok for a few days after a reset. Thought the problem was that the doors wouldn't actually open on command as found a charred door brake pcb in the door motor assembly. Replaced that along with the DO/DC contactors (poor contact resistance). Still the same issue with entrapments, though the doors now return properly after interrupting the safety beams during the closing phase. Previously, the doors were slow and juddering. Then i replaced the LVC and LV1 contactors, as they were also giving intermittent continuity across the contacts when manually toggled. (LV2 replaced last year). Anyone got an opinion on the Magnetic sensors on the car? and if so, what is the most likely culprit. I can access an Otis tool from a colleague, what should I look out for reported back?
Thanks in advance of your input
