Well, I couldn't see how to open up the foot controller, but there were lots of twists in the wire connecting the foot controller to the machine---how in the world that happened I don't know (maybe it gets spun around when I chase it with my foot???). I untwisted the wire and straightened it best I could. Stitched a little on it and the same thing happened while I was stitching fairly slowly. Turned machine off and then back on and did some FMQ stitching pretty fast and it didn't happen. We'll see what happens in the next couple of days.
