International Comfort Products HHP430GKA1 Limit Switch
Limit switches were created because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch is a type of sensor switch in the heat exchanger that decides when the air is warmed to a point for the air to begin normal home circulation.
What happens when my limit switch really needs to be replaced?
- The system starts to behave differently on more than one occasion
- The heating and cooling system is unable to start or continue to run as it should
