Craftsman Garage Door Opener Problem
I bought a house with a Craftsman GDO that had stripped nylon gears. I corrected that, but now it does not work properly. I adjusted the up and down force and the up and down travel distance, but when I push the button to open, the chain will travel only about 5 inches and stop. If I push the button again, it travels a few inches and stops again, always pulling the door up. It never reverses. With the cover off of the chassis, I can see that the gears are turning properly. It ignores the "up" travel sensor and tries to keep lifting the door. Anybody got any suggestions? Thank you.
