Samsung UCC2400C Limit Switch
This is important because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air. The limit switch contains a sensor in the heat exchanger that can determine when the heated air is warm enough for the main blower to kick in and circulate the air.

- The heating and cooling system will not even start or continue to run even though max temp has not been reached
- The whole system starts to become inconsistent time after time
