I have an overhead gas blower furnace in the garage. I had it
serviced last winter when the transformer fried.

Trying to fire it up for the first time this year, and the pilot won't
light.

I'm sure that the gas supply valve is open.

I thought maybe I just need to wait for the air to purge after opening
the valve, but I held the pilot button down for about 5 minutes, and
it still won't light.

Should I hear a hiss or smell gas, or the amount involved in a pilot
too small?

If you can't smell the gas, there isn't any for one reason or another.


Thanks.

Here's my furnace:

If you're inclined to check it out, the style of my pilot assembly is
on page 13.

Should I try removing the hood? These furnaces are ridiculously hard
to get around in. I removed the sheet metal bottom in order to access
the pilot.

Should I mess with it or call a pro?

I don't have an air compressor, but I have a can of compressed dust
remover for computers and electronics.

It's non-flammable. Should I give the orifice a blast?

Are you following the instructions for how to light it?

E.g., with some (most? all?) you need to press the pilot "button"
_while_ you try to light it (with e.g. a match), and continue to
hold it down once lit until the bimetal valve heats up and it can
sustain itself.

After 5 minutes, I would have thought you would smell it. But I
haven't always smelled it immediately. People's noses differ.

If it's accessible easily enough to go sniffing it, it should be easy
to see if it can blow bubbles with soapy water. One std way to check
for small leaks, very small leaks.

You may just have to manually hold pilot valve open for a while until
gas gets to the unit.

From what you say, and the way you say it, I'd first check the gas
supply.

OK. Verify that you have followed carefully the instructions on
page 12.

I wouldn't.

If after following precisely the instructions on page 12, and several
trials (I've found that I sometimes don't get the match flame in quite
the right spot to light them when I'm working in contorted positions
g), I'd opt for the pro.

I don't have an air compressor, but I have a can of compressed dust

I doubt it would help.

Definitely. You have to hold down the spring-loaded red button.

You may want to backtrack and see if there is another valve that is shut
off. Maybe you shut a valve off when you thought you were opening it.

BTW for most of this worlds population the sniff test should be enough.
For me, after years of sinus infection and hay fever, I can't count on it.

This is Turtle.

With what you have said here. I will say you have a restriction in the
gas flow from the meter outside to the pilot head burner. this can be
may number of things like Gas valve somewhere shut and you not know it,
Pilot adjustment screw set too low or has trash in the pilot lite
needle in the gas valve to set the flow of the gas to the pilot valve,
or even to you did not pay your gas bill last month. SO.

When you push the red button you over ride all valves and everything
that would hold the natural gas back which tells me you have a
restriction of some kind of the gas not getting to the pilot lite to
burn.

It can take a LONG time to purge the air. If nothing else is wrong, that's
an IF. IF nothing else is wrong then just be patient. There are dangerous
ways to purge the air from the gas line but I wont mention them here. Be
careful.
