Is it a Tempstar, Keeprite, Heil, ICP furnace?
How about a model and serial number?

Oh, I get it: making me /work/ for my free advice! Well, I can play that
game as well as anyone.

The furnace is labeled "Goodman Manufacturing Co," model GMP100-4 (rev B)

Mounted on the frontside, above the burners, is what appears to be a
squirrel-cage blower about 8'' across in an enclosure. The input side
faces into the furnace. This blower exits into a 5'' diameter round
metal (galvanized steel?) vent pipe that vanishes up into the ceiling of
the furnace closet.

When I turn on the heat, the sequence of events is:

WHIRRRRR (the turbine sound, comes from the squirrel-cage blower)
pause for 30 seconds
Tik-tik-tik (piezo starter)
"Whump" (gas ignites)
pause another minute or so
Vwoooooom (main furnace blower pumping air into the heating ducts)

After a short bit of time, the small 5'' duct gets hot. What do I have
here -- a furnace with a forced-air burner chamber exhaust? Never had
such a thing before.

Oh -- I forgot. In the morning, shortly following the "WHIRRRR" of the
small blower, you can hear the dead awakening and cursing the noise.

Now that helps a lot.
Oh, the free advice...............its not free.
hehe. You thought I was goina tell you for free what people pay me
for. Yur killin me man.....yur just killin me.
