International Comfort Products C2A324GKA100 Limit Switch
The limit switch contains a sensor in the heat exchanger that determines when the heated air is actually warm enough for the blower to be activated. Limit switches were created due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air.
