  • Check photo eyes (small black boxes on the framing near the bottom of your garage door). Make sure the lights are on in both eyes. If no lights are on, call for service.
  • If one photo eye light is on, but the other light is off, they have been knocked out of alignment. Take the photo eye with the light that is off and move it until the light comes on. There is a small butterfly bolt that you can loosen to move the photo eyes into alignment. Be sure to tighten the butterfly bolt after you make your adjustments. Also check to make sure the vibration of the door does not make the photo eye go off again.
