Duplex set up. Problem is on both doors. Got two blinking lights instead of three on board. When powered on, three lights blink three times, Then continuous two blinking. Doors are not being detected on service tool. Works in inspection mode. But in normal operation it goes straight to nav. Tool says doors are unavailable. With power on, door slides open with no resistance. We switched out the door operator board and the control board. Did not help. Any suggestions.
