Three parts of Lennox furnaces generate Lennox furnace error code C2: The airflow switch, the pressure switch and the vent fan switch. If any of these parts are incorrectly installed or damaged, it may result in a high resistance in these switches, which will lead to a high current output and a power surge. Air is introduced into the furnace at various points to maintain a smooth combustion process, but if there is too much resistance.

The Lennox furnace error code C2 is an error code that is generated when the burner does not light up for any reason. This can be because of a faulty pump, wiring, or a clogged burner nozzle.

The flame sensor monitors the flame in the furnace and ensures it stays lit. Air flow sensors measure how much air flows into your furnace to ensure it has enough oxygen to light a fire. Air flow sensors also control when your motorized blower turns on and off, which helps maintain even heating in your house.

Another cause of this error code could be a dirty or clogged burner assembly. Carbon buildup on the burner can cause issues with ignition and reduced airflow, which would produce C2 errors in your system.
