j have mentioned on hear before, but i took my Janome 9000 to get it looked at because it would speed up on its own and keep sewing even after i took my foot off the pedal. he told me it needed a new motor. long story short, it cost me $189 and it didnt fix the problem. the next year -it was still doing the posessed thing- he told me it needed some sensor and it would be very expensive. anyway i found out it was the footpedal and DH cleaned the dust and cat hair out of it. i contacted Janome about problems with the motor-they'd never heard of a problem with the motor. when i bought a new Janome i didnt go there. i also tell people not to go there too.
