International Comfort Products T9MPV075F12B1 Limit Switch
The limit switch is a type of sensor switch in the air handler that decides if and when the air is warm enough that it can be circulated throughout the house. The main reason limit switches are made is 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 HVAC system will not even start nor will it stay running like it is supposed to
