You may not have the same problem I had. One of the screws/bolts (I don't remember which) came loose -- from the mechanism that runs the feed dogs -- My son, who was a SM Mechanic for 14 years put the screw/bolt back where it belonged and guess what -- it worked. So, you may need to check the under side of the machine. Another thing, is make sure the lint is cleaned out around the bobbin case and under the needle plate. A build-up of lint can slow a machine to the point of total failure of the working parts, a failure which can be remedied by cleaning out all the lint. There are any number of reasons -- it could be the power cord -- of it has any breaks, the power court could halt the machine's operation. The foot control could be bad, or your motor may be burned out.
