Carrier 58STA110 Limit Switch
A normal limit switch contains a sensor in the heating area that can determine if and when the air is warm enough that it can be circulated throughout the house. Limit switches are crucial due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.

- The HVAC system starts to become unpredictable more often than not
- The HVAC system will not begin the ignition sequence or continue to run as it should
