Carrier 48GS036060300 Limit Switch
The reason limit switches exist is because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch has a sensor in the heat exchanger that determines when the heated air is warmed to a point for the main blower to kick in and circulate the air.
