I have a four year old Harman Advance pellet stove. One evening, while we were sitting around enjoying the heat, the thing went clunk and, very slowly, the fire died. We turned it off to let it cool down, and the next morning we turned it back on, but pellets would not dispense into the burn pan, or whatever the place in which they are burned is called. On the side of the stove, we have LEDs for everything but the blower, and when we put it on test, the blower works fine but no pellets are pushed into the burn pan. Is this a simple case of a jammed auger, or will we need to replace the circuit board?
