Carrier KFCEH0401N03 Limit Switch
The limit switch has a sensor in the heat exchanger that senses, or governs, when the heated air is warmed to a point for the air to begin normal home circulation. The main reason limit switches are made is because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
Indications limit switch is in need of replacing
- The HVAC system begins to erratically more than once
- The HVAC system will not begin or continue to run as it should
