It was cold enough for the heat to go on, and although the fan started
blowing (forced hot air system), cold air was coming out. I went downstairs
and I see that there is no ignition, so I'm guessing the ignitor is shot.
This is a 10 yr old American Standard, Freedom 78 unit. The question is, is
the igniter something I can change myself, or is it time to call the heating
people?

had
attempted to do it myself, I don't even know where I'd get the part.

Good point.

That was the point I was trying to make:

It's not rocket science, but how much is piece-of-mind worth?

I'd check for current at the igniter with a multi meter. If you have
current at
the points the igniter connects, when the ingniter is supposed to heat up,
then
I'd try a new igniter. That's what I'd do.



Current flow with a bad ignitor??
Nope ain't gonna happen.

So, do you agree that it sounds like a bad ignitor?

No, It could be, but it could be other parts too.
No, I will not give someone advise on fixing their gas furnace over the
'net. I do not know your limitations!

I fully understand, I wouldn't want to do that either, because you don't
know who is on the keyboard, at the other end. Sorry I made is sound like
you *had* to give me advice. I sincerely did not intend to.

In any case, I just finished replacing the glow plug. $26 for the part, one
screw to unscrew, one plug to unplug (not even 5 minutes total time), and
the house is already a roasty 66 degrees. Luckily, it wasn't anything more
serious.

I would still have it looked at. on most forced air gas furnaces, the
fan will not come on until the output temp rises to a factory set temp
and runs after the flame goes out to cool down the heat exchanger.
someone may have "worked on" your furnaces in the past.

As I remember it, the fan came on first from the day they installed it,
about 10 years ago. The only person that has worked on it, in the past, was
the HVAC person servicing it.
