A:Answer A simple way to confirm the wiring is okay is to push the green button on the Insignia Controller on the ceiling quickly once. If the door does not move, it means:
1- the cable is not plugged in all the way to the controller, or
2- the wires are not inserted in the terminals on the back of the motor unit all the way or
3- the wrong pair of terminals are used on the back of the motor unit or
4- you have an incompatible garage opener.
Check your garage opener's wall mounted control button, if it has a "Learn" or "Program" button it is not compatible. Sometimes the learn button is hidden under a folding panel. You can see the verified compatible models here:
