    American Standard Freedom 90 4 blink code
    I have an American Standard Single Stage Freedom 90 unit and just yesterday. It stopped blowing warm air. I have power cycled the unit and adjusted the thermostat and still nothing. The blower kicks on instantly and I don't see any spark or flame when looking at the venturies. My LED is blinking 4 times. I have seen things on other threads like ignitor or limit switch. Can anyone help me?

    Locate the legend for the status light, usually found on one of the panels or on the control.
