Carrier 58CVA13510022 Limit Switch
A normal limit switch has a sensor in the heat exchanger that can determine when the air is actually warm enough to activate the main blower. One big reason why limit switches are designed that way is because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
Symptoms poorly running critical limit switch
- The system is beginning to behave differently often
