Recently, my garage door opener quit functioning. The button on the wall is still lit up and the program light comes on when you hit the button so I know it is getting power. When you try to activate it, all I get is a "click"... lights don't come on or anything. The sensors are aligned and are functioning. I was thinking it could be the capacitor, but wouldn't the opener lights come on if that was the case? Faulty logic board? Thoughts?
