Our garage door opens fine, but it won't close right. The above head light blinks and garage door stops and re-opens. How can we fix this?? Any suggestions would be helpful. Thank you!

My first guess is that the electric eyes are misaligned. They are on each side of the door track, about 6 inches off the ground.

See this post (https://www.askmehelpdesk.com/home-safety-security/craftsman-garage-door-opener-keeps-opening-when-trying-close-520605.html) for more details.

Good luck,
