    AC blower fan will not run in auto, only "ON". (heater runs in auto fine).
    AC problem. My blower fan will not run in auto. (heater runs in auto fine).
    The fan will run in "on" position. I suspect the timer (or maybe a limit switch if there is one) on the fan control board. Does anyone know where I can get a schematic for the Lennox BCC2 fan control board?

    Thanks

    Actually, I am looking for the board (BCC2) schematics. I am thinking that a timer or relay is bad. The board is shown in the wiring diagram, but not the internal circuit.
