Carrier 38TSA042 Limit Switch
A normal limit switch is a switch in the heating area that can determine when the air is warmed to a point for the main blower to kick in and circulate the air. A limit switch was crafted due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts.
