There is a thin spring steel bush that is located inside the cavity of the knob( all 3 knobs), sometimes it just quits the plastic knob and rests rather on the chamfered shaft, it could be shoved deep down that it loses contact with the knob and this is why it seems so loose doing nothing. Without that steel bush the knob works nothing, just turning around the shaft.
