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
Rick

Should be on the back of doors or panel

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.
