When I press the wall switch, the garage door will move forward a few inches and then stop. If I hit the switch again it will reverse back to the starting position. If I keep doing this a few times it will eventually close all the way. But then when I open it up again it will start doing the same thing.
I have no idea what to look for. The floor sensors are all clear of debris and the infrared light is strong and obstruction free.
Thanks for any help.
