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 .

Another post not worth wasting time on because there is
no complete description of the problem, actually very
little to go on. Amazing how people expect answers when
they don't give the most basic info.
