Trane XE78

[lorraine52955]

I have a trane XE 78 furnance, it will kick on, but then go right off again, it was working but then would turn off but continue to blow cold air, now it just blows cold air, we had a problem like it last year, had to clean the flame sensor, but I can not remember how to find it, can someone help me?

the flame sensor is right next to the pilot flame orifice. you may need to remove the whole assembly, burner tube too to gain access to it.
