Hello .. Rich here .. kets see if I can help you with this
lets check a few possibilities .. is there any obstruction to the door closing? ... could tyhe sun be shining on the door sensor ? is there anything that is getting in the way of the sensor , like a pull rope ?
I cleared one of the "visibility" problems but the flashing light problem and the intermittent switch problem still exists and you never addressed that in your answer. The Poor Service rating still stands.
