International Comfort Products T8MPN075F16B1 Limit Switch
A normal limit switch is a switch located in the furnace that can determine when the heated air is warmed to a point that it can be circulated throughout the house. Limit switches exist because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
Hints limit switch has little life left
