Craftsman Garage Door Opener Problem
I recently replaced the gear and sprocket in my 1991 craftsman garage door opener. I put the opener back up and everything worked great. The door the started to act up so I adjusted the up/down force to the maximum force. Everything seemed to work fine for a while until now. Now the door opens fine but will only close a foot or two and then reverses. I unhooked the door from the carriage and it still does it which tells me it's not the door. This is an older garage and there is no sensors anywhere. I about ready to give up. Anyone have any sugggestions? Thanks in advance.
