My furnace is calling for heat but is not igniting. In the past it has taken a while to fire, sometimes it fires quickly. I have not torn into it yet, it is in the cold attic and we have the pellet stove running, but I am thinking it is the igniter. My manual is showing part #1009524 and doing a search I am finding this: Does that look like the correct part and how hard is it to replace? I just replaced my gas dryer igniter and pellet stove igniter so I guess it is the season for igniter replacements. Forgot to ask: Do you test the same way as the dryer igniter, with an ohm meter?
