Gas valve stems on a KM2012 are greased at the factory, and after a decade and a half that grease has hardened. The knobs then become stiff, notchy, or turn past their stop. Valves can often be removed and re-greased rather than replaced, which is a considerably cheaper outcome and one worth asking about before a full set of valves is quoted.
