So you had a PA2 and put in a PA7 right? If you have a 1/6 HP motor it should bea PA6, PA7 is for the 1/2 HP motors but I think it should work anyway.
1st thing, make sure the communication plug is plugged in to CON7 not CON3. I think the labels sometimes said CON3. You will have to be plugged into the controller, open IMS and door smart fast. There is a setting in the door for discrete operation, don't recall if that will not allow comm. is the PA7 brand new?
