Thanx for a reply.Dodgeman.Tis an old furnace and the fan limit switch is a honeywell.The fan runs all daylong and doesn't cut out whenyou turn the heat down.Three pointers for off,on and off.Going clockwise 250,200,150,100 and 50.What do these numbers mean and where should I set the pointers?I'd like to have the fan come on when I turn up the heat and I would like the fan to stop when the burner goes back to just the pilot light.
