Larry,
I have both problems actually: I either get too much heat because the valve
won't fully close or too little because it wont fully open. I cant seem to
get the control range of the knob to match the control range of the valve.
Others have mentioned that they are having the same sort of problem. At
least I'm not alone!
Thanks for the suggestions, I will try these.
Thanks and regards,
--Scott
