The Coleman Downflow Gas Furnace circuit board burned out. We can't see the wire's colors. I would like to know where or if you could help download a schematic for this furnace. Its a: Model#:DGAT056BDD; Serial#: 960251761. You can email to my address or email a phone number that would be able to assist. Thank you for you time.

Most furnaces have a circuit diagram on the furnace someplace. Is there a circuit diagram available on th furnace?


You shouldn't be dependent on the color of the wires. If you have a reasonable understanding of circuit diagrams you should be able to trace the circuit from connection to connection regardless of color coded wires.

If you don't have a resonable understanding of that, it's probably best to hire a repairman to replace the circuit board. It's not unusual for new circuit boards to have different connections or features which requires you to be able to adapt the new circuit board to work with your furnace.
