I recently purchase a used Clayton woodburning furnace. I need a wiring schematic but so far everyone I received from US Stove is for wiring a Honeywell. Ths furnace is a model 7.1 and doesnt have honeywell equipment. It has a printed circuit board with 3 connectors The top connector has two wires which go to the draft blower; the middle connectoris for power to the circuit board. the third connector has 4 wires, black blue red and white. I need to know how to connect these to run a 3 speed blower. If someone has a Clayton woodburner with a circuit board your help would be greatly appreciated.
Here is the parts page for a clayton 7.1, it does not show any PCB. It does show a limit kit and that is the only thing even close to what you are talking about. I think someone may have changed the wiring and pcb on your furnace. DO you have a picture?
I bought the Clayton Stove (used) a few years ago and have the same board that you do. mine was working up until one of the connectors shorted out.
I'm not an electrician, but when the stove is running, there is power from the black (hot wire) going to the board. Once the box gets up to temp, one of the colored wires on the four prong connector goes hot, and the rear blower motor kicks on.
Please let me know if you need any more specific info....
