Carrier 58CTX09010016 Limit Switch
Limit switches are crucial because if the air never warms up then you will never get hot air through the ducts. The limit switch is a type of sensor switch in the heating area that makes the determination when the heated air is actually warm enough to activate the main blower.
What are some indications that my critical limit switch has to be replaced?
- The heating and cooling system refuses to kick in or run for any length of time
- Your system is starting to behave erratically from time to time
