I have a Comfortmaker RPJ II gas furnace with an electronic igniter (no
standing pilot light). The furnace and the fan come on when signaled by
the thermostat but the furnace does not light. No flames come out of
the burners. I've tested this with two different thermostats thinking
our old thermostat was not turning on the furnace. But you can hear it
come on. Any ideas what else would keep the burners from lighting/ not
igniting? or what the problem may be? There is no smell of gas. Any
help would be appreciated. Thanks.

You need a new thermostat. You just got a bad one.

Hi,
If it's electronic ignitor(Piezo electric) You can hear it when it's
activated. Zap, zap, click, click kinda sound. If you don't hear it
then ignitor module could e bad. There are many things which can
malfunction. What is trouble code?

Piezo electric ignition in a gas furnace???? Did you know you have to push
the button every time it calls for heat? I found some replacements for you.
http://web.ivenue.com/allparts/productCat77269.ctlg

The model # of the furnace is GNJ050N12D1.
I don't hear the zap, click sound which used to come before the sound
of flames.
A previous post mentioned a trouble code? Where can I check that?
I don't think it's the thermostat. I replaced my old one thinking that
was the problem. But with the new thermostat the exact same thing
happens: the furnace and fan come on, but the furnace doesn't ignite.

Did you polarize the thermostat when you installed it? Comfortmaker needs
the thermostat polarized and sync'ed with the controller board before it
will work correctly.

I didn't see any LED signals. There isn't a list of codes anywhere on
the furnace either.
After more trouble shooting I'm thinking it's the igniter. Usually the
first thing you hear is the click-zap sound of the electric igniter.
That no longer happens. Can a non-professional like me replace this
part or try to service it?

Hi,
If you can see if the module is getting power when it needs to activate.
If it gets proper power and nothing happens(no sparksO, then module is a
suspect.
Problem is the module like that is often non-returnable once you buy it.
So unless absolutely sure, it's a gamble. But it's known to fail.

Tony might be guessing since he seems to be mentioning every part on
your furnace.
Do what Oscar says and try polarizing your thermostat. Get a small
jumper wire and with power applied to your furnace, briefly jumper the
R & C terminals together at the furnace 7 times.

Hey meathead--you're not in the HVAC group. Your crap doesn't fit

MLD

Polarizing requires a Modulating Current meter. Many VOM have them
now, they call em VOMM, for Volt Ohm Modulating Meter. Sure sounds
like your low voltage moduator might be out of synch with the circuit
board. I remember the days when you had to manually synch the
modulator every time you serviced a unit. That could take as long as
an hour, if you had to go through the six or seven cycles of bootup
which were required to fine tune the synch.

I think Oscar has a more up to date manual than mine, but some new
furnace autosynch. Just turn the power switch off for half an hour,
and make sure the case of the furnace is properly grounded to drain
off the high impedance farrady charge. Of course, Os will provide the
specific details, being a helpful fellow as he is.

As Steve reminds you, there are many reasons why a furnace would fail
to fire. If you just go replacing parts, it could easily cost more
than having the repair guy out.

You tried thermostat, and that didn't help. The next part(s) you
replace may be both expensive and unnecessary. At this point in time,
best to call the repairman. Before the weather gets colder, and the
rate schedule goes from "fall" to "winter".

Ah, the art of internet diagnosis. The answer in general terms is that
people who can do something just go ahead and do it. The fact you're
asking tells us that it's beyond your skill level.
