Product review (2 stars): NOT A QUICK CHANGEOUT BECAUSE THE WIRES AREN'T LONG ENOUGH.
I can't comment on whether it works yet or not because I have to do extra work before I can hook it up because all the wires are 2-3 inches shorter than the OEM board that comes on the Norcold 3163's and it won't fit in the same place where the original board is!!  Grrr.  A number of folks in my Eurovan campers group all said they had the same issue.  Because the relighter connection is on a different spot on the new board, it's only long enough to reach that spot when the board is moved to a different position as it only reaches it in one position.  But, when you do that, it makes the two white (interruptor) wires not long enough and the green (ground) wire *barely* long enough.  Relocating the board to a different spot on top of the fridge means that the other wires won't fit.  Very frustrating that this could have been easily resolved had the wires been slightly longer.
