Door won't open-buzzing noise
Just installed a new .5 hp Genie screw drive. After everything is connected, STB showing the right colors, I press the wall button to open it for the first time. All that happens is the lights come on and a 1 second buzz sound, like I got the answer wrong in a game show. The door works manually. The wall control is a one button, otherwise I would suspect something is locked. Thoughts?
