Got to love those little black burnt things. I just fixed my buddy's furnace this month for not hundreds of dollars. Main failure: no ignition followed by three strikes and you're out. Root cause: burnt black thing. New control board was $$$, over 200. New black thing plus a foot of bad solder was under $5. While we were in there, we replaced the hot surface ignitor too. It cost more than the little black thing (omron spst relay).
Hope xringer finds a little burnt thing in his unit.
