Carrier KFCEH1601315 Limit Switch
The reason limit switches exist is due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts. The limit switch contains a sensor in the heat exchanger that senses, or governs, if and when the air is warmed to a point for the blower to be activated.
Simple warnings that your limit switch most likely is crapping out?
- The system is starting to behave differently frequently
- The heating and cooling system refuses to kick in or run even though the desired temperature has not been attained
