An "nF" code after a surge, with the flame going out after about 5 seconds, usually means the board isn't sensing the flame anymore. Surges often damage that circuit. Clean and check the electrode first. With serial 1124814, the 621269001 is the right board for your N841, but it's discontinued, so the Dinosaur 6212XX is the replacement. It also covers the 3-way version.
