International Comfort Products PGC030K060A Limit Switch
A normal limit switch is a type of sensor switch in the air handler that decides when the heated air is warmed to a point for the air to begin normal home circulation. Limit switches exist because if the warmed air is too cool then you will never get hot air through the ducts.
What are some hints that my critical limit switch is crapping out?
- The HVAC system will not initiate or continue to run for any length of time
- The International Comfort Products system is starting to stop suddenly more often than not
