Payne PA1ZNA042000AAAA Limit Switch
The limit switch contains a sensor located in the furnace that determines when the air is warm enough for the air to begin normal home circulation. One big reason why limit switches are designed that way is because if the air never warms up then you will never get hot air through the ducts.
