All, The Furnace is located in the crawlspace (Rudd from 1988). It seems in the winter when I have the heat on the furnace will work fine. When the heat light on the thermostat turns off the fan continues to run. The Fan switch on the thermostat is set to Auto. It will stay on for an average of two to four hours or longer. I would like the the fan to only stay on for five minutes then turn off. I do not want to waste so much electric running the fan.
Thanks
