    My 5-year old high-efficiency ICP furnace won't stay lit with the burner panel on. With the panel on, I look through the little window, and the last burner (where the flame sensor is) flickers and then goes out after 30-60 seconds. The fan keeps going and it cycles through that way a few times...

    Hi, I have the Trane XE80. I have a few flame sensor questions: 1. Does this appear to be the correct replacement: http://www.amazon.com/gp/product/B00ECEENHG/ 2. That flame sensor angles a bit differently than the original, is it ok as long as the flame hits it some place? 3. The furnace...

Last year, I had trouble with the flame sensor (don't remember symptoms) which I was able to solve by removing it and cleaning it thoroughly with steel wool. I started up the furnace for the first time last week, and it ran fine, but...
