Nice! Anyone have a Pfaff 7550 that will not sew? Mine turns on like it should but when I push down on the foot pedal .. nothing.I do know it is not the pedal as I plugged it into my other Pfaff 7550 and it works fine. I tchanged out pedals on both machines.. my original machine is making me sad. Lol. Thank you for any clues on the problem. Nana
