Carrier 50XZ036300 Limit Switch
The limit switch contains a sensor in the heating area that decides if and when the air is warm enough to activate the main blower. One big reason why limit switches are designed that way is because if the air is not warm enough the you will lose all the heat as the air flows through the ducts.
