I had a repairman over to look at my furnace yesterday. I was having a
problem where the furnace would not light up everytime it kicked on. It
would start the flue fan but not release gas or light the ignitor when it
failed, other times it would work just fine.

The repairman replaced the pressure switch and said it was working better
already but that there was a problem with the control board as well. I
decided to just have it done(new control board around $260/1yr warranty),
but he didnt have it with him and was supposed to come back today.

I've found the board for $128 online and was wondering if it is very
difficult to install(repairman said it was easy, but he gives 1yr
warranty).

Should I just cancel the board install and see how it goes and install it
myself if it continues to fail or should I just have them do it and get the
warranty?

The furnace has not failed to function properly since the pressure switch
changeout, but it may just be luck or not enough time for it to have failed
yet...

Thanks.

Maybe he just wants to sell you a board

So you get a warranty and labor for about $130, plus you get it done
right and today rather than with the possibility of issues and some
time in the future? I like to do things myself when possible, but
that doesn't sound like a bad deal to me.

JMHO, of course.

I would be "slightly" skeptical. Parts dont usually fail in pairs.
THEY CAN but not usually. You may want to question him why it needs a
new board. You may wish to wait and see if the pressure switch alone
takes care of it. Id wait and see or get another opinion. You can
always get and install the board yourself but as already stated,
you'll get no warranty and you may not even need it.
Good Luck

Hi,
Pressure switch is very easy to test. It's simple on/off switch
triggered by diaphragm at certain pressure range. There just could be
some dirt or even drops of water in the air hose. The control board is
based on sequential logic. I went thru whole thing on my Carrier furnace
just before winter. What kind of error code were you getting? This will
give a clue to the cause of the trouble. Lot of times, vibration and
heat causes cracked solder joints on board.
If you really have bad board, it's easy to replace it by just moving
wire harness, plugs one at a time in parallel after turning off power.
Some boards are not exact replacement. It cocmes with instruction and
wiring adapters, etc.
In my case, high Watt resistors on board had poor cooling under the
plastic cover and the excess heat caused solder joint crack. I
reinforced the joints and drilled a few holes on the cover for more air
circulation. Now we're in dead winter and furnace has been working just
fine. BTW, error code I was getting was pressure switch(which does not
mean it is bad. Just it's a clue. Start trouble-shooting from there.
As a retired EE(from Honeywell) I am surprised some HVAC people has very
minimal knowledge of electronics. They create lots of wasted time and
material.

Thanks to all that have replied and will.

During my lunch break I went home and turned the furnace on and off as many
times as I could in an hour and the furnace never failed to fire.

I decided to call and cancel the control board install. If it starts acting
up again I can call them back or do it myself, I'll decide which route when
and if the time comes.

K..just curious...been having a hell of a time with the new lines they have.
Im REALLY glad that Robertshaw got their act together and York got bought
out by Johnson Controls..
Wasnt flaming, just curious really.

Same thing has been happening with me.., hate to have numb-nuts service
kid come out and charge $300 bucks for a small little bread-board thing'y.
But, also hate fall'n off the g'dm roof at 66 years of age..!!
I think Tony forgot to mention little red light on the board which
"blinks" and gives the "codes". If it's steady on, then the board is
okay.., if it blinks a number of times, then it does have a problem.
Another thing, if you order an electronic part.., you can't usually
return it.., I think.., got'a watch for that!! The part I need is the Spark
Igniter.., which is $200 dollars alone.., plus the service call.., but then
I would have the warranty..!! Sooo, what'a gon'a do..??!!

Oh.., I just looked at mine..., blinking 5 times.., anybody know which code
that is? It's got to be the igniter.., anybody know what kind of current
comes from the bread board to the igniter? If it's the board.., it's $200
bucks..!!

Its the "if you were qualified to properly diagnose the board you could save

Look at the furnace installation/owners manuals. You should find the code
explanation in the troubleshooting section.

Hey guys.., your kill'en me with the come backs.., BUT helping..??
NAHHHH..!! I think the Ben Dover was the right one.., but what about the

Keep it up guys...!!! I'm an aircraft inspector.., what'a I know..??

I would most likely replace the guy diagnosing the problem with a guy
that knows how to dagnose the problem.
You see, several of us have access to this really GREAT crystal ball.
It comes in handy most of the time. Right now, I have it. It almost
always tell me that you need to replace the thermostat because
thermostats always cause most of the problems.
Now when CBHVAC gets it, it tells him other things because he rubs it
with the other hand. :-)
Maybe you should come borrow it and see what it tells you. Right now
its cloudy so its not telling me anything. I'll have to reboot and try
again tomorrow.

I appreciate you!

Today is the international day for the mentally disabled.
Please send an encouraging message to a mentally
retarded friend--as I have just done for you.

Just thought I'd let your retarded ass know I don't mind
being friends with you. I don't care if you lick windows
or even if you wear a football helmet to work.

It doesn't bother me that you wear your underwear on the
outside of your pants. You hang on in there because
you are doing great! You are special, so keep trying!

Have a great day you Goofy *******!

Geeez guys.., loads of hostility out there. Now Oscar, where you talk'n to
Bubba.., or me.., or us..??!! Better watch it man.., cause Bubba got's them
"crystal balls" (smile).., and ain't to be asked questions this early in the
morning. Funny what happens when you get on these "friendly" newsgroups..!!

Okay.., to end the stupidly the 5 code on the board meant it was fried..,
so what you want'da do is carefully note where all the colored wires were.
Then carefully remove the board (making sure the circuit breaker is
pulled).., new board, and reinstall. In my case $200 bucks with senior
discount.., but saving $60 for diagnostic trip.., and $100 labor..!! And I
didn't fall off the roof either..!! So here's a beer for the rest of you
guys, and the old finger to Oscar somewhere out there in la, la land..!!
