Changing the Code on Craftman Garage Door Opener and Remote
Please help. I have a repairman coming in one week that will cost a min. of $70 and if I can figure out the problem before than I would appreciate it. I have a Craftman 1/2 hp. Opener Model: 139.53515SR The Remote is model # 139.5377B It has 9 pins inside it that can be moved up or down. The opener has a white "Learn" button on it with a red LED light next to it. If anyone knows how I can fix this. The battery is good, but the opener doesn't work. I had a foster son that messed with the pins inside the remote and they are all in the same position. I don't know if this means anything or not.
