Why does the electronic beeper beep and the sewing machine won't sew?
I have a Singer 7462 Electronic sewing machine. When the foot pedal is depressed the electronic beeper beeps and lights flash but the sewing machine doesn't sew- I tried suggestions from Singer site but it didn't solve the problem. No sewing Machine repair in this area.
I think there is something jammed in your sewing machine: motor belt, bobbine,gears. etc. Try desconnect it from main and clean it. Then try to rotate it forwards and backwards looking for the part that is stuck. Some times the nylon gears breaks and get the machine out of order and stuck.
I hope this hints may help you,
