Need some advice. Norther TC 181 -- door would only open 1/4 of the way and only in the mornings. ONce the elevator warmed up or 5-15 minutes later it would work fine the rest of the day. After replacing motor and GAL ECI board in operator, we diagnosed with Northern and they said the relay board (9806 board) was bad. WE replaced but NOrthern said it is plug and play -- it is not necessary to cut jumpers, replace the U Chips (U1, U2 etc. chips). Is this true? We have never replaced a circuit board where the U chips and the jumpers didn't have to match. Car doesn't run right with new board -- we put the old board back in. Can easily move the U chips over, but Northern said it wasn't necessary?
