International Comfort Products NHP242AKA1 Limit Switch
A limit switch was crafted due to the fact that if the air inside the furnace is too cool the you will lose heat in the ducts and the vents will just blow cool air. The limit switch is a switch in the heat exchanger that decides when the heated air is warmed to a point for the main blower to kick in and circulate the air.
Key indicators that my limit switch is on its last leg?
- The heating and cooling system refuses to start or continue to run like it ought to
- The system is starting to behave erratically on a regular basis
