I have a janome 9000 and it was sewing on its own-was really ticking me off because i was appliqueing and it wouldnt stop and i would have to rip out the stitches. took it to my dealer and he told me i needed a new motor. like a dummy i didnt check to see if janome ever had issues with the motor soo $187.00 later i have a new motor and it was still doing it!.not all the time-just when i had to get something done NOW! long story short, i borrowed my friends foot pedal and my machine workrd fine-put mine in-sewing on its own. my DH was in the room at the time and took apart the pedal and cleaned the dust and cat hair out of it and it hasnt given me a problem since. the thing is- i asked my repairman if it could be the footpedal the 1st time i took it in. he said its not the pedal and i got the new motor. the lst time i took it in he said he called Janome and they said it was some sensor under the feed dogs. anyway it would be very expensive to get to it. I have since learned that he has ordered parts the machine didn't need and charged people for them. I now have a new repair guy and a new dealer. anyone need a motor for a janome 9000? LOL
