Carrier 50XL-A60 Limit Switch
A normal limit switch is a type of sensor switch located in the furnace that makes the determination when the air is warmed to a point for the main blower to kick in and circulate the air. A limit switch was crafted because if the air never warms up the you will lose all the heat as the air flows through the ducts.
Key indicators that my chief limit switch is dying?
- The whole system is beginning to runs uneven more often than not
- The HVAC system refuses to start or continue to run longer that five minutes
