It does feel as if there is no resistance to it and it is just spinning freely as I turn itThey often malfunction because previous owners didnt know how to use them. Its likely the thread has been damaged.
If they are working properly, the rpms should go up immediately as you turn the knob. It could be an adjustment issue, but I dont recall ever having to adjust one.
