This is excellent advice. Download the 58 page 2004 Atwood Furnace Service Manual and read it. It will show you how your furnace works, and has diagnostic sections that are very useful. Like others, I would check the sail switch. It isn't easy to get to, it is behind the large blower wheel on your furnace. If it needs replacement, it must be replaced with one specific to the model furnace you have. I'm not sure that the lack of a battery is the problem; if your converter puts out a solid 12V, the furnace should operate (and since the blower does turn on, it's probably okay).
