Nordyne E3EX-020H Limit Switch
The limit switch contains a sensor located in the furnace that makes the determination when the air is actually warm enough for the air to begin normal home circulation. Limit switches are built because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air.
