Carrier 58DLX13510016 Limit Switch
The limit switch is a type of sensor switch in the heat exchanger that can determine if and when the air is warm enough for the main blower to kick in and circulate the air. Limit switches were created because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
What happens when my limit switch most likely has to be replaced?
- System will not start or run well for any significant length if time
- The system is beginning to go through the startup sequence but stops quickly often
