Help! New Machine Family Sew 550S Servo Keeps Stopping

[Colt W Knight]

My service has a pot, and I can select anywhere on the dial, and it does that click into place. The slowest setting my machine will sew is between the 350 and 660 hash marks on the dial. It has the pulley that came with motor.

If I set mine on 660, it sees pretty fast, but I can feather the pedal and make it walk slowly.

My Family Sew motors have multi-position rotary switches, with resistors coming off the terminals. The highest 4 speed settings are all the same speed, having no further effect on the top speed. The remaining positions (5th and under) each have an obvious effect on the top speed. When I set them at the 350 RPM position and floor the pedal, the walking foot machine turns over at about 2 stitches per second (without a reducer) and the CB4500 at about 1/2 stitch per second, with a 3:1 reducer.

Something is definitely wrong with mine then. I'm surely calling my dealer. Thanks so much for helping!

I just wanted to follow up and thank all who tried to offer help. I really appreciate it. The steps Wizcraft gave was enough to inform me that it was definitely an issue with the motor. My dealer is awesome! They promptly sent me a new one and it works like a dream. Now I can make it "walk" like Colt Knight's! Thanks guys!
