If the knob is loose, please do NOT overtighten the set screw. This will surely result in the knob being stripped or split.?
If it's loose because the shaft is hard to turn, remove the knob and fix the problem preventing the rotation (usually some thin oil in the shaft/bushing of the control) , then reattach the knob.
