Customer Question

I have trane xr80 unit. when it cycles off, the blower continues to run. a board, I believe the furnace control board has a burn mark on it. a trane dealer technician told me I needed a $600.00+ board. I found some online for less, but I was not sure what it is called. I believe it is a cnt03797 or cnt03797 or a 156-74579 but I am not sure.

If you can get me the model number (the xr80 is the series) then I can tell you exactly what board to get.
