my furnace is not heating up. the blower comes on and it is just blowing cold air out. It is not igniting. I have a Lennox Model C23-26-1 this is the first time I had trouble with this furnace in 11 years. Can you help ?? I noticed a green light blinking and when I turned off the blower and turned it back on it was steady green but NO hot air.

0 The roll-out switch has to be reset. Turn the furnace off, and remove the door that is not for the fan compartment. The switch is located in the area of the furnace near the burners and will have 2 wires that run to it. In-between where the wires attach will be a small button. Just push it in, and you should hear a click. That's It! Replace the door & turn the furnace back on and it should run fine. Check to see your filters are clean.
