Why does my garage opener light flash 3 times and click 3 times, but the door will not go down when I push the wall unit button?
I have a Craftsman garage door opener. The model # is 139.53925DS I am also wondering if both sensors at the bottom of the garage door need to glow green or can one side glow green and the other side orange? I am trying to understand why my garage door light clicks 3 times and flashes 3 times and the door will not go down. If there is a short in the wiring, where do I look?
