Suburban SF- 30 furnace

[redrhinino]

This morning, I got up, and fired up the front furnace on my 2006 Tiffin. We had set it super low (60°), and it was about 62 in the coach. Ran it up to 69°, and the unit started up. Several minutes later, I heard it shut down. It still seemed pretty chilly in the unit, so I went to turn it up a couple more degrees, and I saw the temp at 65, while the setting was still at 69. Turned the of, back on and set it to 69 again. The fan started, ran about 20 seconds, then shut down. I checked the limit and sail switch, both seem good.

Since it just shut down while it was running I don't think it's the ignitor, but I can't hear the little click click when i try to restart it.

So, where to next? I don't hear the ignitor, and since it dropped out while it was already running originally, should I just assume the board is bad, and order another? if the board failed, could that keep the ignitor of as well as just shut it down?

Here is a place to start ( link below ). And any RV parts place worth it's salt will be able to test a furnace circuit board if you walk in the door with it, in hand.
