How to fix Singer TouchTronic 2001 only able to do straight stitch?

Re Singer Touch-Tronic 2001 memory machine Sewing Machine with touch control in picking stitches and built in decorative stitches. Can pick the stitches but the machine only will do a straight stitch no matter which stitch I pick, no matter if it is reverse, zig zag, decorative, longer, wider, etc. It only goes forward in a straight stitch. Manual suggested to press the red reset button (circuit breaker) which I did but still have the problem.
Any help is appreciated.
