Hello all, I bought my home in March 09 and there is an AS freedom 80 HE two speed furnace (2003) in it. When I initially whet to start it I got nine flashes and removed the ignitor (silicon nitrate, 80V) and it looked like it was glowing for six years, it was very thin in the middle almost like some one whittled it like a twig in the middle. So I went and bought a new one which was a small fortune, $+ and it started and worked fine. About a month later the same thing happened so I replaced it again. About a month later it happened again so I called local supply houses and Trane/AS and they said they have no idea what the problem is other than dirty electric or a bad board ($+) so we installed a capacitor. It worked fine for about a month then summer arrived. I turned the heat on two weeks ago and it worked fine until I got home yesterday, the ignitor is smoked again. All voltage is fine. Does anyone have any idea what the problem is?
