    I turn my heater on and set it to auto, It will run through a cycle no problem but after that the fan does not kick in at all and I have to set from "AUTO" to "ON" in order for my heater to distribute the heat with the heater fan. Is this a relay issue not working correctly?

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...
