Carrier 48GP030040300 Limit Switch
The limit switch has a sensor in the heat exchanger that decides if and when the air is actually warm enough for the blower to be activated. Limit switches are crucial because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air.
Key signs of an unhealthy critical limit switch
- The heating and cooling system will not begin the ignition sequence or run longer than 10 minutes
- The Carrier system begins to act differently time after time
