International Comfort Products H8MPN100F14A1 Limit Switch
The limit switch is a type of sensor switch in the air handler that determines when the heated air is warm enough so that it may be pushed through the ducts and out the vents. Limit switches exist due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts.

- The HVAC system will not even start or will not stay running like it should
