I have the exact same swing with the exact same problem, sometimes it will come on and sometimes it does absolutely nothing. It has made me very angry because i took it apart and cleaned the internals up, when i put it back together, it worked fine until my baby wanted to swing the next day, and then it refused to work again. Now the pile of junk is sitting at the edge of my yard after i slung it out the door. My advice, Throw it in the trash where it belongs and go buy a different brand because Graco is TRASH.
