My Lift-Master model 1255K door jams only when the door comes up. The problem started happening the other day. The door opens past the point where it has been adjusted to stop and jams up against the end bolt. I unjammed the door by loosening the chain and checked the 'UP' travel adjustment to make sure it was making contact. I checked it with a multi-meter to make sure the contact was making a good connection and it was fine. I tested it a few times and it worked fine. If I wait 5 minutes or more to open the door it will jam again. I removed the receiver logic board and I checked for cold solder joints but there were none. Is there anything else I can do to resolve this issue. Any help would be much appreciated. Thank you in advance.
