Can't troubleshoot my gas furnace

Hi all, My furnace has conked out, and I can't seem to find anything wrong with it. When I turn the fan from auto to on, it will blow, but then shut off again when I turn the heat from off to on. I have removed the upper panel, and the light is green, all switches are set to on, and there appears to be no other electrical issues. The lower panel is held fast with a broken bolt, so obviously the problem may lie there, but is it likely? I have been told the theromostat may need replacing, or that the filters may need replacing (hepa is replaced, electric filter grid being cleaned now.) Is there a top of the list culprit? What things should I look for? Any help very much appreciated! Thanks Red Robin
