I just installed a Craftsman 1/2 hp Garage Door Opener, Chain Drive model # 953971 on a sectional steel garage door and for some reason I cannot get the opener to close the door fully.
When the opener brings the door down, it stops about 12" from the ground and then opener pulls the door up again. I checked the sensors, and door, I can lift the door and close the door with two fingers, so I know there are no obsticles nor allignment issues.
I tried the adjustment on the opener and I was unsuccessful in adjusting the downward adjustment.
I appreciate if you can further any suggestions with issue.
