I just bought a Janome 3000 at a yard sale. Got it home, sewing fine for about 12 inches, then just shut off. the light went off and the machine will not sew. My husband checked the electrical connection. Has power, but still won't sew. Is there a reset switch? Did I do something wrong? Has anybody else had this problem? Do you know where I can get help with it? Thank you for any help you can give me.
