Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
The pulling mechanism which attaches to the garage door moves a couple inches then stops....even with the door not attached. The motor still runs. Motor will not stop until I manually move the mechanism to either end. It seems to be sticking on the track, but I don't know why.
You have a stripped gear on opener. Take off cover and the bottom will be covered in white shavings. Replace with gear and sprocket assembly
