Craftsman Garage Door Opener
Hi-I have a 1990 model#139.53718 Craftsman Garage Door Opener. It only opens part way and it won't close. It doesn't matter if I use the remote or the door wall switch. What could be the problem? When I attempt to open the door, it only opens part way and when I attempt to close the door it begins to close and then goes into reverse but it doesn't actually close. Please help, if I could fix the problem myself I'd rather do that but if I need to call a technician out I would like to be sure that technician is necessary. Also, when I disable the automatic it does work fine manually but of course I would like to use the automatic option. Thanks!!!
