Carrier 58MSA120 Limit Switch
A normal limit switch has a sensor in the air handler that decides when the air is warm enough that it can be circulated throughout the house. This is important because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts.
General indicators that your limit switch needs a replacement ASAP
- The HVAC system will not begin or continue to run longer than 10 minutes
- The system begins to act weird more often than not
