    Furnace turns on, ignites then turns off.
    Furnace turns on and then it ignites then turns off. I checked to see if the thermosat was bad but it wasn't then I checked the pressure swith assuming that was the problem but it still does the same thing. Does anyone know the answer to this problem?
