Anybody good with the Harman pellet stoves? I have a P68 ~6-7 years old. It never really regulated temperature that well but it was acceptable. Lately it has been terrible. Here is what it did when I fired it for this year (was also doing it last year). It ran for about 24 hours keeping the room at ~72 degrees. Then it just would not regulate down. It just sort of sits there in a medium-fire and continues to heat. The room got to 82 before I manually shut it down. Could it be the control board? Is it affected by heat? Can the control board be replaced? I have already replaced and cleaned the "probe" and cleaned the entire furnace. Any clues?
Thanks.
Thanks.
