Mark, how long (if any) does it run AFTER the ignitor quits, before it shuts off?
Too bad we're not closer; still got my "go" bag, probably woulda had it running an hour or two after you called... Steve

Never dreamed this thread would be so long. Sorry guys.
Steve, the flame extinguishes immediately after the igniter quits. I'm convinced the problem is that it doesn't detect the flame... because:
1. The igniter continues for the full 16sec regardless of flame present
2. The Yellow LED on the circuit board never lights
3. Gas pressure at the inlet and outlet are well within spec... purged the system again and didn't blow myself up.
All connections seem good. Worried the circuit board is faulty unless flame sensor is bad.
Gonna pull and inspect the flame sensor and reinstall.

If you look at the flame rod BEFORE trying to clean it (usually not necessary, if so a gray scotchbrite pad) you should see a darkened section of the rod; this is where the flame actually TOUCHES the rod. If that's not there (it should be by now, but not overly obvious) then there's something REALLY wrong (like a loose piece of metal deflecting the flame, or ???
If you have the flame rod out (and NOT shorted out against something) an inspection mirror should show you the flame that would've been hitting the rod - in most cases the flame should be mostly blue(ish) with a few yellow tips (yellow may NOT be there, newer regs want lean burn and yellow is unburned carbon)
You still haven't said whether you have a DMM you think might work, sooner or later that test is gonna get done (whether by you or a $150/hr tech) - let me know if my description a few pages back needs more detail.
Don't worry about a drawn-out thread, I'm a taurus with nearly 75 years practice bein' stubborn; we're done when YOU say we are

Everything I have is old to ancient so not up to date and then only when I have to be.
That said I know you will solve the issue and it will be more nugget of knowledge gained from TBN

From the manual (linked earlier) -
"This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand."
This is "I don't wanna tell you" speak for most likely a piezo element like you find in self-lighting propane torches - more of the "green" movement, doesn't waste gas keeping a pilot going all the time... Steve
Woah, way to sneak that in when I wuz tryin' to show off :laughing:
+ 10, "enquiring minds wanna KNOW"...

Yeah that was a bit of a tease... if you know me, you know I won't abandon you all now. Just wanted to see who was paying attention! :laughing:
