Carrier 24ACA436A0030010 Limit Switch
A normal limit switch contains a sensor in the heating area that can determine if and when the air is warm enough for the air to begin normal home circulation. Limit switches are built because if the air is not warm enough then you will never get hot air through the ducts.
Key signs to watch for in a failing main limit switch
- The heating and AC system is unable to start or continue to run even though max temp has not been reached
- The whole system is starting to run inconsistently occasionally
