I have a 1999 earth stove mp35.50. The control board died and I would like to fix it, however, there is no circuit diagram that I can find. Would save a lot of time if someone had figured it even at a block diagram level. A $500 charge for a replacement is like robbery. I had a career as a field engineer fault isolating and repairing Broadcast equipment at the component level, so Im sure I could fix this circuit more quickly with a diagram. However, I will go ahead guessing at the most likely suspects in the circuit path. SYMPTOM: It stopped feeding pellets, motors and wiring are good. Any help appreciated.
