Carrier 38EYG060 Limit Switch
The limit switch contains a sensor in the heat exchanger that can determine if and when the air is warm enough to activate the main blower. The main reason limit switches are made is because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air.
Key symptoms of an unhealthy limit type switch
- The heating and cooling system will not begin the ignition sequence or run well like it is supposed to
- The system is starting to initiate and then stops on a regular basis
