International Comfort Products NTPM125KNA1 Limit Switch
The limit switch has a sensor in the heat exchanger that decides if and when the air is warmed to a point so that it may be pushed through the ducts and out the vents. Limit switches are built because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
Some warnings limit type switch is in dire need of a replacement

If you are going to be buying or purchasing, do your due diligence and cross-check the model number and also make a visual comparison in order to be sure the correct limit switch is the one being purchased. You do not have to install the replacement part alone. Locate a pro in your community to pay to install it for you.
