It was cold enough for the heat to go on, and although the fan started
blowing (forced hot air system), cold air was coming out. I went downstairs
and I see that there is no ignition, so I'm guessing the ignitor is shot.
This is a 10 yr old American Standard, Freedom 78 unit. The question is, is
the igniter something I can change myself, or is it time to call the heating
people?
