    There should be a sheet or instructions somewhere on your furnace. Might be on the blower door.

    I have narrowed the problem down to the combustion blower. The fan blades are rusted and broken. So now I need to replace the blades or the complete assembly. It Is A Concord model RGH80 Furnace.
    1. How do I find a part Number?
    2. Were is the Best place to check for the part?
    3. About how much do you thing It will cost?

    Thanks for your help
