I installed 2 liftmaster 3800's about a month ago. The both function fine, however I am having an issue with one of the remote lights. The light comes on when the door opens, turns off after 4 minutes or so, and functions fine when the door closes. However if the door is open and I walk through the door and 'break' the safety sensor beam, the light will not turn on. Any ideas?
Thanks
