    My furnace will not stay lit
    I have a Trane XL80 furnace. I have manually started the furnace and at the time the burners will light and continue to fire for about 5 minutes then they act like they are being blown out. The LED light at the time of start up begins to blink 4 fast blinks. The blower continues to blow cold air even after the flames go out. Any ideas of what could be wrong?

    If they act like they are being blown out you better get your heat exchanger checked. This could be a dangerous situation.

    I just went by what you said

    ((they act like they are being blown out))

    Look at the sticky notes in the beginning of this board and look for the legend on blinks on the diagram on the door of the furnace.
