In a fit of PPPPPPP* while at DAV earlier this month, I decided to test my furnace before actually needing it.

The fan started normally, gas valves opened, and...nothing...but a faint smell of propane.

The natural thing was to suspect "no spark", so I replaced the control board when I got home. Flashed it up, same thing.

Pulled the burner and ignitor, and removed a fair-sized mud dauber nest from the burner, cleaned the crud out of the holes. Reinstalled, flashed up...same thing.

Now, the spark had been tested (it worked), and it's getting gas, so why won't it start a burn? Maybe it's not getting enough gas?

Pulled the burner, and discovered some kind of fluff obstructing the orifice; cleaned that out, and it runs fine now.

I generally fall back to: "It's amazing what you find when you look."

We've all been there.

Is this an example of "if it ain't broke, fix it till it is", or "it's broke, now fix it dammit!"

Rusty,
I had to laugh at this one.
I forgot to mention this several weeks ago.
The airhorns weren't right so I went up on the roof to check the covers -- made a quick retreat and got a ladder and leaned it on the front windshield. After using almost a half can of wasp spray I removed the horn covers to find that both horn openings were almost completey shut off with wasp nests. Of course then I went on a hunt all over the old Barth.
They are bad this year.

Been there, done that...some years ago, I was puttering near my electric meter, and heard arcing in the meter can. So I clipped the seal, opened the box, and shut it quickly. A horde of yellowjackets had homesteaded it.

At this point of the story, I thought you were going to tell us how much a new windshield was... Glad to see that wasn't the case.

That's what I was thinking when I read the ladder was placed against the windshield. I know I've certainly had those moments when fixing one simple thing turns into fixing another larger issue because of not always thinking.

OK Guys I'll take the ribbing on this one.
I ladder ends weren't really on the windshield.
I had it extended to the area just below the clearence lights. Anyways I got them before they got me. Also behind the water heater cover.

i can tell ya new windshields for a 88 regency is 249 each here in alabama lol But i didnt break it with a ladder it was cracked when we bought her
