Carrier 58STA13510022 Limit Switch
A normal limit switch contains a sensor 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. The main reason limit switches are made is because if the air is not warm enough the you will lose all the heat as the air flows through the ducts.
Some warnings critical limit switch needs to be replaced
- System will not even start or will not stay running longer than a minute
- The whole system starts to act weird occasionally
