You mean the fan/blower ? There's a temp sensor in the heat exchanger that
turns the fan on/off assuming your furnace is that old , newer ones are
microprocessor controlled . Looks like a little box with a disc inside and
some pointers on the disc . Try rotating that disc , carefully so you don't
change the pointer settings . You ARE closing the blower box door aren't you
? There's an interlock switch there too that'll kill the fan .


Does your furnace have a separate on-auto switch for the fan? Turn
it to on to see what happens.
