Well it seems that my origional assessment was correct except for different reasons. The pellet stove went down again and I was unable to revive it. The repair guy can't get here until this Friday so we have a radiant heater running. I'm thinking it's not quite as drastic as the control board needing replacing but could be. I'm thinking one of the thermal switches went out which is much cheaper. This based on some troubleshooting I did already.
