Carrier FE5A Limit Switch
The limit switch contains a sensor in the air handler that makes the determination when the air is actually warm enough for the main blower to kick in and circulate the air. Limit switches exist because if the warmed air is too cool then you will never get hot air through the ducts.
Subtle cues of a laboring limit switch

- The HVAC system begins to ramp up but then stops more often than not
