    The good thing is that its under first year parts and labor warranty. You can check to make sure the gas valve is set to on and all gas shut offs or open. If the system had a flame failure you will need to turn the power off and then back on going to the furnace to reset the control board to let it retry again.

    What is the sequence of operation before your problem starts? Proper sequence would be stat calls for heat --> Inducer (exhaust) motor comes on --> Ignitor glows --> Gas Valve opens creating flame --> Heat exchanger heats up enough to open limit --> Blower comes on to circulate air... how far do you get?
