    Furnace control board wiring and thermostat?
    With the help of a neighbor, I just installed a new blower motor on my furnace. Furnace is located in crawl space and AC unit is on side of house.

    We feel confident we wired the motor correctly. However, on the main panel/wiring panel/sensory panel, White Rodgers 50TC35-730 there is a scanner bar code on a black chip that reads 50T35-730-01 and underneath, B18099-13.

    The issue is now this, I turned the AC on auto and it worked great! No more short cycling. However it is cool today so I turned the AC to off and the blower continued to run. I checked the outside unit and it was off however, the blower was running strong.

    I currently have the power turned off to my furnace unit so it would quit running.

    Am I missing something on the thermostat wiring to the panel? I don't think its my thermostat as I just put in a new one two weeks ago and everything turned on and off correctly so I think we may have mis-wired something below.

    One last bit of info, two weeks prior from install of new fan motor, I put in a new thermostat, switched from mercury to electronic. The thermostat worked fine prior to install of new blower.

    Please help!

    Please any ideas or help would be appreicated!
