OK. Here is the 9-page Payne 394 JAW PDF that Carrier sent me today:

I was hoping to just debug the (much simpler?) thermostat first, but,
since someone asked about the furnace, I went down there and noticed
the door was off.

When I put the door back, the blower just blew incessantly.

So I took the door back off, and pressed the white switch that gets
pressed when the blower door is on, and the blower just kept blowing
for as long as I held the switch pushed in.

Back upstairs, teh cover is still off the thermostat, so the thermostat
settings are still at HEAT (versus OFF, COOL) and AUTO (versus FAN ON).

This is the schematic printed on the inside of the door panel:

This is another smaller schematic above that big one on the door panel:

And, this is on the outside of the door, for the electric pilot:

What I'll do right now is read up on the net for how this furnace
works, and the first thing I'll do is try to identify the parts.

Hi,
Close the cover. And shut the power off to the furnace for 5 mins or so
and turn on the power. What happens now? Still fan comes on? Then we'll
do next step. Usually when hi temp limit switch(fixed temp. thermostat)
triggers furnace flame shuts off and fan runs to cool and when that
switch opens, fan will stop. I don't think your furnace is hot now.
Just maybe thatr switch is stuck close.(this is just one of possible
scenarios)

If this is the case furnace will lock up 2 hours something like that.
By turning power on/off you can defeat that 2 hour wait to try again.
Is it cold there? It is -14C and light snow here today.
