    Furnace troubleshooting
    I have a natural gas furnace. Took it apart to clean blower motor.. (took motor apart)
    Took heating elements out and cleaned coils. All back together and works fine... but blower motor runs backwards..

    Look at the wiring diagram on the motor connection cover. Reverse the wiring. I am a bit confused however.. "natural gas furnace ....took out heating elements and cleaned coils "_--in a gas furnace?

    The motor connection should show wiring for CW clockwise and CCW counterclockwise. Apparently you have one of those wires reversed. The colors you noted are fan speed and capacitor start, not direction.
