Absolutely right.

I appreciate all the input, yes it would have cost me a lot and for what
turned out to simply be a resetting of that limit switch.

Good part is that I learned my furnace mechanically inside and out. Only
costs me about 100 and have a spare board now.

But after trying everything I could think of, after bypassing all the
safeties and bypassing things I was just perplexed.

Thanks again

You are absolutely right. There is a reset button hidden between those
two
terminals in the upper limit switch in that heat chamber.

Wow, nothing I read in my manuals said anything about that reset button.
And
I paid a technician to come in and diagnose what was wrong, he told me
to
clean out the condensing housing there, re-silicone that as that may be
clogged up but it wasn't and I did that. He also told me he was 99% sure
it
was a failed board and for him to replace was 300 plus the board, I
purchased a board for 80 and did it myself and dam, same problem
existed.


Excellent. Sorry I didn't see the thread sooner, it would have saved a
lot of
time and money. You will probably want to keep the board. Most places
won't
accept returns on electrical parts. It's too easy for someone to swap
their
defective part for the new one and try to return it. People try that more
often
than you would believe.

It's not surprising that the "technician" told you it was the timer
board. Look
at what it cost, and what he was going to charge for it. In most areas,
there is
no licensing or certification necessary at all for someone to repair
furnaces.
If someone presents you with an expensive repair estimate, always get a
second
opinion. It might be worth the price of a service call to discover that
you
really don't need it after all. Ask family, friends and neighbors who
they use,
how many times they had to call them, and were they satisfied.

Glad I could be of help.

Some of those boards cost silly $$$$$...Even wholesale price.
I always dread having to tell someone they need a new one,
because it's usually a pretty high bill, just because the
price of the part is so high from many of the manufacturer's.
It's usually the dinky fan relays that go TU if one actually
does go bad.
Some companies seems to be semi reasonable.. But some of the
biggest brands like Lennox, Trane, etc.. Ouch... Often around
$225-$250 wholesale just for the part.
You have to be licensed here, but even that doesn't mean the
guy isn't a crook.. :/
They have some companies here that are so big, and have so
much overhead, that they almost have to rip people off to
stay in business. I can think of one in particular here locally
that I hear lots of complaints about. They have a big monster
dispatch center that looks like Mission Control at NASA, lots
of overhead, loads of trucks, etc.. And they have expanded to
other cities in the state.
They rob nearly everyone they deal with.
