    Intertherm Furnace
    My intertherm furnace was flashing a 2 blink code saying that the centrifigual switch failled to close in the aloted time so I replaced it (which it was bad) I also replaced one of the pressure switches that would not give a reading on the volt meter, I also replaced the electronic igniter as well, so now when I turn it on it glows, the flame ingnites for about 3 or 4 seconds then it goes out and it starts the procsses all over again heats up for 3 or 4 seconds then out again over and over, anyone have any ideas?
    Thanks

    Sounds like you have a dirty flame senser. If you can locate it, remove it, and clean it with steel wool, sand cloth, or fine sandpaper, you may be back in heat. Please let me know how things turn out.
