Lennox furnace error code C2 is one of the most common errors on Lennox furnaces. This issue, which is mainly related to the airflow switch, can be solved by simply checking for clogs in the filter and cleaning it.
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.
One important thing to note about this error code is that it does not necessarily mean something is wrong with the gas valve. The gas valve has two settings: ON and OFF, which are regulated by the switch on the panel board. If the ON position on the switch is set and there’s still no flame, there’s an issue with wiring or a clogged nozzle.
This problem is common among Lennox furnaces, and there are multiple causes for this issue.
The most popular reason for a C2 error is a bad sensor. The most common sensors are the flame sensor and the airflow sensor. 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.
lennox furnace error code C2 is the code that has been developed to be a trouble code for those who have Lennox furnaces.
While it can be frustrating to have a problem with the HVAC systems, knowing the error codes will help you troubleshoot and fix the issue. The Lennox furnace error code C2 means that there is some kind of fault in either the air system or indoor air quality sensor. You may want to check these two parts before calling for an expert’s help.
