Laughed at all the replys ........ my machines are ALWAYS fixed by my husband as he is one of those who can do everything (and I'm not kidding). Of course, I don't own any machines that are computerized because I know he will refuse to even attempt one of them. Mine are older, simple machines. He does the cleaning/oiling, tension adjustments if I'm stymied, smoothing of parts that seem to get slightly out of whack - and when one simply quits he has it purring again in an hour or so.
