Janome machine speeds up
I have a janome memory craft machine. It works great then all of a sudden it speeds up the only way to stop it is to unplug the foot pedal. Thinking it is the foot pedal started only using the start/stop button and iit does the same thing. At this point I have to stop it by turning the machine off. If I am doing embroidery it can go perfect thru some projects but then all of a sudden it speeds up and has to be turned off by on/off switch. Of course I loose the project I am working on. It has been in the repair shop in the past but still does it. Has this happened to anyone else?
