Carrier 25HPA424A0030010 Limit Switch
Limit switches were created because if the warmed air is too cool then the house will never get warm enough. The limit switch is a switch in the air handler that can determine if and when the air is warmed to a point for the air to begin normal home circulation.
Elements to watch for in a failing limit type switch
- The system is starting to act differently from time to time
- The heating and AC system will not begin the ignition sequence or will not stay running longer than a minute
