Have a slightly faulty board on a Otis MCS 120 Hydro. Elevator works perfectly apart from the car-top down inspection button and the machine room ERO down inspection button which means I had to replace board when insurance man reported it as a defect.
Seems a waste to bin it so does anyone know which component is likely to be faulty and if it's an easy fix.
Should add that I was getting no BC LED lighting when the down inspection button was pressed
