An "nF" (no flame) code after a voltage spike usually means the fridge lights but the board can't sense the flame, so it shuts the gas off after a few seconds. That points to the flame-sensing circuit on the power board, which surges often damage, or to the electrode. Check that the electrode is clean and sitting in the flame. If that's fine, the board is the likely problem. For a 2003 N841 (including the 3-way), the Dinosaur 6212XX replaces the original board. Send us your serial number to confirm.
