Garage door operner woes- sensor, logic board?
door won't close, and blinks like it did when something's in the sensor path. The sending sensor indicator light is on, but the receiving indicator light is not. Even when putting the sensors directly together the receiver indicator light is not on.
I'm in process of checking for a wiring short to the reveiving sensor. I'm assuming the problem would have to be either the sensor, or the logic board, correct? Which would more likely be the problem? I'm thinking of buying replacement parts swapping them and see what happens.
Or if I try the service repair route, what would be a resonable service charge for the labor repair?
