Carrier 38BYG060 Limit Switch
A normal limit switch has a sensor in the heating area that makes the determination when the air is warm enough to activate the main blower. This is important because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts.
What are the indications that my limit type switch really is dying?
- The HVAC system refuses to start or continue to run for any length of time
- The HVAC system is beginning to become inconsistent on a regular basis
