Does anyone have the circuit diagram for the Earth stove 35/50 pellet stove? I am an electronic technician and want to fix the faulty board on my pellet stove. The replacement board costs over $400 and it is probably a component that is faulty. As an alternate, I will have to trace out the circuit or even replace it with a microprocessor based control board. The unit was first sold in 1995 in N California, has been in use every since with only a draft fan replacement. Very sturdy unit.
