Carrier 50GX Limit Switch
The limit switch has a sensor in the air handler that can determine if and when the air is warmed to a point for the main blower to kick in and circulate the air. The main reason limit switches are made is because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.

- The heating and cooling system refuses to kick in nor will it stay running like it is supposed to
