While it is clicking check to see if there is voltage from circuit board to the gas valve.
Another is to verify that the two coils on the gas valve have continuity.
OK, so checking voltage across the closest coil's positive and ground wires, for the first thing, and then continuity across the positive of one coil to the ground of the other?

Your burner is either dirty or the spark electrode is not adjusted to spark between the burner and the electrode. Odds are the electrode is sparking to the top of the combustion chamber which will not ignite the LP. Doug

How do I adjust the spark electrode? The gap at the tip was 1/8" last I checked, which seems to be to spec? And thanks, I went to the University of I Own a Late-Nineties RV and I'm Kinda Broke. You'd be surprised how much you learn there!

try taking off the high voltage lead off where the burner is and placing it close to the metal frame and see if it sparks when it tries to light or not. Had mine do the same last week we had it out, it was a bad Neon (NE2) lamp near the High voltage coil fixed it …
Yikes, that seems a little spooky to test out. Would I hear the spark electrode clicking during ignition (as I do) if it wasn't sparking?
