The 628663 is the optical display board (front panel), not the power board. For the N412.3, the power board we list is the 621268001 (N41X/N51X 3-way), and it has been discontinued by Norcold. Your "NR" serial is a newer format, so please send us the number on your removed power board to confirm. The 628663 has a 2-3 week lead time. The N412 is discontinued, and the closest current Norcold 3-way model is the Norcold N4150. See our Norcold replacement guide.
