    Tempstar furnace
    Furnace is not staying lit, it a temstar LP forced air # nulk100dh06. If I turn the thermostat up after it has just shut down, the ignighter lights the burners they run for a few seconds, the blowerkicks on and as soon as it does the buners shut down. I shorted out the thermostat, and get the same results.

    Try cleaning the flame sensor.
