Payne PY2PNB036090AA Limit Switch
The limit switch is a switch in the air handler that senses, or governs, 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 due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts.
Some clues limit switch will not live much longer
