If the blower is working that means the furnace is getting power.
Unless you know /exactly/ what you are doing, a furnace is one thing
you should not fool with.

The fact that I assume 120 volts (and whatever the high-tension leads
have in them) is there, is the key reason why I'm not just jumping
leads just yet.

I want to *measure* first. That's not dangerous. Jumping things is
much more dangerous (if I make a mistake).

So, at the moment, I concentrated first on identifying all the parts
of the furnace (which I snapped a picture of and posted separately).

Then, I am concentrating on figuring out how those parts play together.

After that, I'll do the measuring.

And then the jumping.

I'm sorry I'm probably way slower than you guys would like, but, I'm
trying to actually understand the darn thing first ... Thanks for
your patience. I've still got to read that Carrier manual ...





Start with the basics:


1) You have determined that the furnace has power. That's good.

2) Turn the thermostat down below the temperature of the house...
Have an assistant stand by the thermostat and now go to the furnace.
When you are there have them turn the thermostat up.


Does anything at all happen?

Of so...describe what it is doing and post back.


If *absolutely* nothing happens, then a wire on the thermostat could be
broken.


If you hear a click and gas starts to flow, but nothing ignites, then it
shuts down...then the igniter is bad.
