Lennox CBX32M-018 Limit Switch
The limit switch contains a sensor in the air handler that decides when the heated air is warmed to a point so that it may be pushed through the ducts and out the vents. This is important because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
