Carrier 58STX07010012 Limit Switch
The limit switch has a sensor in the heating area that makes the determination when the air is actually warm enough to activate the main blower. Limit switches were created because if the warmed air is too cool then you will never get hot air through the ducts.
Key indicators that my limit switch most likely is almost dead?
- The heating and AC system will not even start or continue to run like it is supposed to
- Your system begins to behave erratically occasionally
