The Polar N7/N8/N10 boards don't use the same pin-jumper reset as the older N6/N8 boards. To reset one, turn the fridge off and disconnect 12V DC (pull the fuse or use the battery disconnect) for a minute or two, then reconnect. If the display comes on for about 10 seconds and then goes out with no code, check for a solid 12V at the board (low voltage often does this) and check the fuses on the board. If those are good, the Power Board 639593 is the likely cause, and it's in stock. See our N7/N8/N10 help article.
