    Furnace blows cold air
    Carrier Furnace model is 58SCX120 - When initial request from thermostat is made, furnace starts up correctly. After the initial heating cycle, the furnace often blows cold air. The inducer fan and the blower continue to run but there is no flame. The cycle seems to be locked up. I have replaced the flame limit switch and checked the pressure switch located on the inducer assembly. I have also checked the drain to alleviate excess condensation build up. It is clear. When the flame is on, it looks strong and even with a nice blue flame. Igniter is operational.
