It goes by serial number, but I would recommend you get the board kit 633291. That will upgrade both boards!

Norcold N510.3 power board 28-pin microchip "bug" part # ??
Hi, thanks for answering my previous question (N510.3 optical control board), but did I understood well that the kit # 633291 is the correct one for my model? Actually, my electro-guy found out the error was in the micro-controller chip part # PIC16C621A-04I/P PDIP18, which we´ve replaced with the similar PIC16C622A-04I/P PDIP18 (the only difference is a bit bigger memory capacity, which should not be an issue) and re-recorded the memory - a $ 3 solution. But it did not cure the problem, which still persists, and seems there is another issue, this time in the power board. We detected failure in the 28-pin microchip, which unfortunately does not have printed any designation number. The complete power board circuit has # 621268, but those which I found available with this part # are described as for a 2-way model and there is one combined shape "black cube" (a kind of relay?) missing (Potter & Brumfield T9VAV1D12-12). Your e-shop offers this part # 621268 less the 2nd relay, but the description says compatible with 3-way models. The only power board where this 2nd relay is included is a part # 621271(001), but this is described as compatible with Norcold 1200 series... Also not clear to me what´s the difference (in terms of compatibility) between the power board # 621268 and 621268.001. Regardless the compatibility, the cost of the power board itself is roughly $ 250 (depends on the source), while the kit of the power board and the display control board is around cost approx. $ 280... My Lancer camper module is a 2002 model, so the N510.3 fridge must be the same year or very close before (serial # 1017667L). A question is - is it worth bothering to replace the power board, the display board (or both) in cost of $ 250-300, when the complete new fridge unit sells for about $ 1,300.- ?? The best solution would be finding out the part # of the 28-pin "bug" type to replace it instead of the entire board... Could you help with this?? The point is I am located in Europe, so the delivery time and the shipping cost (in case of the whole new fridge) is a concern, besides the confusing compatibility of the correct power / control boards, and I´d really like to avoid spending hundreds of bucks for ordering a wrong part # power board, particularly when the failing "bug" itself can be replaced for a cost of few bucks only.... Thanks, Filip
