Craftsman 1/2 HP garage door opener
I have a Craftsman Ã¯Â¿Â½ HP garage door opener circa 1998 with a 41A5021-3C logic board and 130.53681B remote control (which came with it). I put a new battery in the remote. When I push any of the three buttons on the remote, the light on the logic board flashes, but the door does not open. I have a built-in remote in one car (Honda Accord). It opens the door. Is the logic board or the remote bad? Or is it something else?
