Carrier 50XZ042300 Limit Switch
The limit switch contains a sensor located in the furnace that determines when the air is warmed to a point to activate the main blower. Limit switches are built due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts.
Key clues to watch for in a failing limit switch
- The HVAC system refuses to start or continue to run like it is supposed to
- The Carrier system is starting to runs spotty more often than not
