Carrier 48XZ042060300 Limit Switch
A normal limit switch contains a sensor in the heat exchanger that makes the determination if and when the air is warmed to a point for the blower to be activated. One big reason why limit switches are designed that way is because if the air never warms up then you will never get hot air through the ducts.
What are the indications that my limit switch most likely is not working right?
- The system is beginning to act differently more than once
- Your Carrier system refuses to kick in or run longer that five minutes
