Sears Garage Opener 139.53716 Help Don, please
Don, thanks for the responses, sorry its taken so long to get back to you. The 2 wires, split into 4 go from the garage door motor to a door opener button outside the door to the house and to the part I am trying to replace (yes I bought a new one),the button before you go out of the garage. There are additional plug in wires that go to the outside keypad, they are not the problem.Yes I have replaced the 9 volt.This is an old unit, I am thinking of replacing the entire garage door system. I can't attach the 4 wires to the 3 screws on the back of the new part!
