Carrier FB4CNF060 Limit Switch
The main reason limit switches are made is because if the air is not warm enough then you will never get hot air through the ducts. The limit switch is a type of sensor switch in the heat exchanger that decides when the air is warm enough for the air to begin normal home circulation.
Key signs of a failing limit switch
- The HVAC system begins to act weird occasionally
- System refuses to kick in or run even though max temp has not been reached
