If it won't come back on after you turned it off, start with power. Check that you have a solid 12V DC at the fridge (the fuse at the RV panel, the fuse on the power board, and your battery voltage). Norcold boards won't power up with low or no 12V. Also check for loose or corroded connections at the board. We have a couple of good write-ups: Norcold won't turn on checklist and my Norcold won't turn on.
Just so you know, the 633287 board kit on this page is for the N641/ N841/ N1095, not the N821. If you want help diagnosing it, our tech support service is a good option.
