Carrier 48XZ042060300TP Limit Switch
Limit switches are crucial due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air. The limit switch is a type of sensor switch in the heat exchanger that decides when the heated air is warmed to a point for the air to begin normal home circulation.
Major clues of an inadequate limit switch
- System refuses to start or continue to run even though max temp has not been reached
- The Carrier system is starting to act differently frequently
