International Comfort Products PGC060L100F Limit Switch
Limit switches were created 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. The limit switch is a type of sensor switch in the heating area that makes the determination when the heated air is actually warm enough for the main blower to kick in and circulate the air.
What are the clues to watch out for to know my chief limit switch has to be replaced?
- The heating and AC system will not initiate or will not stay running like it should
- The International Comfort Products system is starting to shut down unexpectedly more often than not
