Carrier 24ANA124A0030030 Limit Switch
The limit switch is a type of sensor switch in the heating area that can determine if and when the air is warm enough for the blower to be activated. Limit switches are built because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
General indicators that your main limit switch needs replacing ASAP
- The HVAC system is unable to start or run like it should
- The Carrier system begins to behave erratically occasionally
