Re: Intermittent Open Sensor Problem
Most likely Door B either needs the magnet closer and aligned properly or
the contact in the frame is intermittent. Try redrilling the mag in the
door after you mark where the door now closes to. Also, if there is a large
gap at the top, lessen the gap by not pushing the mag all the way flush.
Bet it's the alignment. Good luck.
