I knew there was a service bulletin at some point, couple years ago right? I called my Trane locally and he said replacing the combustion blower will end all my problems. Was that the fix, new combustion blower motor? I thought there was some sort of relay kit as well.
Here you go, kit part numbers are included. I had to replace every board and both the high voltage and control wiring harnesses on the last one I did. Trane however came good for all of the parts because it was less than 5 years old.
