California weather is so moderate that you can live the entire year
sans hear or air conditioning ...
It's only around 32 degrees for a very short while, just a few hours
in the early morning; and then it's back up to 50 or 60 during the day.
We don't even drain the garden hoses ...

Yeah. They call taxes "fees" out here so that they don't need

They outlaw basically everything; again, the people here are too

It's a weird state - but - the weather is excellent - if we could
just get rid of the politically dumb inhabitants.... :)
The funny thing is that the PDF didn't say what caused the igniter to
start snapping. I guess I'll read the PDF again ...
Ah ... found it... It must be the thing called the "pilot igniter".
Here's what the PDF says about it:
"When the thermostat calls for heat, the control circuit is closed
between the terminals R and W. Power from transformer TRAN through
fusible link FL, limit switch LS, and vent safety shut-off switch
VSSS, energizes the pilot valve part of automatic gas valve GV and
*pilot igniter PI*. The pilot valve opens, permitting gas flow to the
pilot burner where it is ignited.
So, I guess that snapping was from the "pilot igniter".
The timer is there to set delays between various operatins and you will
be very confused if you expect things to happen immediatly whenever the
The Thermostat must always be mounted as though it was on the wall so
that the mercury switches will operate correctly.

I need a quick lesson on the parts of a furnace ... and what
they do, before I can diagnose or fix anything! :(
At first, I thought "this" was what you call the "igniter":
But, this youtube video calls that a "3-wire pilot assembly":
Following the red "high tension lead", that video calls this
black box the "spark igniter" (is what you meant?):
This is clearly what that video calls the "gas valve":
This isn't in the video, but, it's clearly some sort of fusible
link and something called a "lockout timer":
The brown board with the fusible link attached has two wires that
go upward to this thing (is it a sensor?), which, unfortunately,
wasn't described in the video:
This compartment was held shut with a 1/4" sheet-metal screw:
Below that compartment was this set of terminals (I recognize
those wire colors as the same as those of the thermostat):
To the right of the terminals, this 3Amp fuse tested good:
Inside the box was what the video named a "fan control board":
And, I observed the basic stuff, such as this door safety switch
(which I taped tightly to keep in the on position):
This is the on/off switch for the gas, which remains on:
The 16x25x1 3M filter was surprisingly clean:
Googling, I found there usually is an on/off switch on the
side of the furnace where the power comes in. Mine doesn't
seem to have that switch; the power wires go right inside
the furnace from outside without a switch.
So now that I've identified "most" of the parts (I'm not sure what
the purpose of the lockout timer and that sensor thing are), it's
time for me to figure out what/how to test and debug the thing...

I think the lockout timer and spark ignitor are two different things:
Here is the spark igniter (I think):
Here is the lockout timer (I'm sure - because it says so):
The PDF doesn't describe the lockout timer; but there is a schematic
pasted on the inside of the furnace door that purports to describe it:
I'm still not sure how it works though - but maybe it is the culprit...
I'm getting close because, for a while, tonight, it was all working:
But, then it stopped as soon as I accidentally allowed the door switch
to spring open (I bumped it while trying to measure voltages).
I was wondering where you were!
Normally, your huckleberries are spot on the mark!
Luckily, with the team's help, the problem is resolved!
It's running now ... after I pulled the plug (yes, it has
a plug) and then disconnected *every* wire and cleaned
them up and reassembled them (one by one, so as not to
make a mistake).
I blew compressed air around everything; and I tapped
with a screwdriver on all the relays (I guess for good
luck as much as anything else).
Wouldn't you know it ... the darn thing is now working!
Will update in a couple of days, to see if it *stays*
