An "n" code on an N821 points to a no-flame or communication fault. Check that you have a solid 12V at the fridge and that LP reaches the fridge. Then clean the burner and check the electrode. If it keeps showing "n," the board may be the cause. N821s with serials below 9126825 took the 637779 kit (discontinued), and the 628661 power board is for serials above that.
