Did you check the thermocouple and the ignitor? Maybe some corrosion or something stopping it from igniting? Is the little red error light on in the switch panel? Propane system charged up? Maybe these might lead to the issue??

Check the diode, mine did that and that was the problem.

Sometimes the gas gets locked up try running the stove for a while see if that helps

If it's not even sparking it could be the control board. Mine went on me. For awhile I could just give the electrode a soft bang and jiggle and it would spark, but then finally stopped altogether.
Got it online for about $120, IIRC. Worked like a charm after that. Local RV parts place wanted a couple hundred.

Like this (http://www.ebay.com/itm/Atwood-Water-Heater-Ignition-Control-Module-Circuit-Board-RV-Camper-93865-/322034605574), but check your model number.

Let us know what the problem was when you get it fixed :) this is a new issue that I haven't had but I'd rather be prepared for.

Not that I know of. I just kinda tried that as last resort. The burner fired up when I got it to spark. The igniter seemed to work. Just intermittently. So I risked the $100 some-odd bucks. RV technician said it's quite common.
Put the new one in and poof. Worked perfectly.
