Craftsman Garage Door Opener
I move into a house which has Craftsman Garage Door Opener 4 months ago. All of a sudden my Garage Door will not open or close with my remote. Except when I hold the panel on the wall to close or open it from inside the garage, then only is when it opens only 1/3 of the way up and stop. I replace the battery in the remote and it did not help. I have also notice that the door sometimes opens only when the light on the wall panel blinks.... Please HELP!!
