International Comfort Products PGC048K080F Limit Switch
The limit switch has a sensor located in the furnace that makes the determination when the air is warm enough so that it may be pushed through the ducts and out the vents. One big reason why limit switches are designed that way is because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air.
Key signs to watch for in a bad main limit switch
- The system is beginning to act weird more often than not
- Your International Comfort Products system is unable to start or continue to run longer than 10 minutes
