The knob I use to select drying time in this White-Westinghouse dryer doesn't move, regardless of whether set for timed or automatic drying. With the dryer running, I measure 120 V across the motor. Resistance across the motor, with one lead disconnected from everything, is 3000 ohms, which is about what it should be based on the 3 watt rating stamped on it. Electrically, the motor seems okay. Looks like a mechanical failure (e.g., gears) within the timer assembly. Anything else I might be missing?
Thanks,
Ray
