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.

You said *NEW* thermostat. Was there an old thermotat? Did the furnace
work before changing the thermostat? If it did, then you probably dont
have the thermostat wired correctly, or it's defective. (anything can
be defective, even new stuff). Of course if the new one has batteries,
be sure they are good.

If this dont help, and you post more, how many wires go to the
thermostat? Is it also for air conditioning? What is the thermostat
brand-model? What kind of furnace?

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.

If it is a hot water furnace, you might check the aquastat.

Then it would be a boiler

Furnaces heat air Boilers heat water

Well, when we had one, I really didn't want it boiling.
180F, good. 212F *very* bad!
