I have a Pfaff 1475CD. When I turn it on it sits and hums for about 45 min and then comes on. what do i do?
You may have a broken wire in the leads or the foot control needs to be repalced (which sounds the most likely problem). Also it may pay to check the brushes in the motor. I would strongly suggest you do not let the machine sit like that, it could burn out the motor or even start a fire. A word of advice for all people with electronic sewing machines if industrial or domestic, YOU MUST have a surge protector & not just plug the machine into the wall socket. These are computers remember.
