Carrier 48XZ024040300TP Limit Switch
A normal limit switch is a type of sensor switch in the heating area that decides when the heated air is actually warm enough for the air to begin normal home circulation. Limit switches exist because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air.
Major symptoms of a deteriorating limit type switch
- The HVAC system is unable to start or continue to run for any significant length if time
- The Carrier system begins to go through the startup sequence but stops quickly on a regular basis
