Just to eliminate the easy, double check the switch. I had one of my Bad Girls slings go out the other day, neither switch appeared to be physically closed (I could see a gap in both) but it must have been somewhere because when I adjusted the leafs further apart that fixed it (if a Gottlieb switch that operates a coil is closed the whole unit will not function at all). That's the extent of my knowledge so hopefully that's it, good luck!
