American Standard Freedom 90 2 flash
I saw an article here on 3 flash codes for the same unit...but I was curious what I should check on my unit that is giving me a "2 flash" code?
The code implies that it has exceeded the number of retries...The pilot light seems to try and light, but it does not stay on that I can tell through the viewing glass. The fan blows after the unit tries to start 3 times.
I opened the case surrounding the pilot light and the burners. Cleaned out what I could see. this included some dead bugs and lint that had gotten into some large air pipe (not sure if intake or exhaust...). Still can not get the burners to light. It tries 3 times then dies...then the fan starts to blow cold air.
