My Trane XL 80 continues to blow air (cool) after flame is extinquished. I don't know if this is a unit problem or theremostate problem. Any ideas?
Thanks for your help!

There is a set of dip switches on the board that change the fan off timing, get the installation guide and set it to around 100 secs

Most likely a stuck relay on the main board
