Moderators SeaDawg Posted May 28, 2012 Moderators Share Posted May 28, 2012 Once again, we had a problem with our Norcold refrigerator giving us an "n" code. This has happened to us once before, but we were under warranty at the time. Since it's a holiday, there is no one open to look at the problem, and I have a refrigerator full of food for this afternoon's cookout. The problem with many of the fault codes listed in the back of our thin manuals that come with the camper is this: if you reset the refrigerator by turning it off and on, and the code reappears, the board locks out all power sources. Even if there is a problem only with the gas operation, the board locks out all power sources (gas, a/c, and d/c) until the board is reset. Resourceful Paul found the manual online, via a forum post on another forum, and it appears that we have solved the immediate problem, at least for now, and are running on a/c power to the fridge. The "n" code can mean a number of things, including inadequate circulation of air to the fins and thermister that hangs off the fins. (This may have been our problem, as the top shelf was packed full.) Other causes are listed in the manual. Here's a link to the manual, which you may want to print off and add to your book. http://bryantrv.com/docs2/docs/n5051.pdf The manual describes two ways to reset the board. One is very involved, removing lots of wires and using a jumper. Not the way an average person would like to attempt, as a wrong move could "fry" the board. The second method restarts modern boards through a series of steps on the control panel. That's what Paul used, so we could try the refrigerator on A/C mode. Directions are on page 56, Screen 6, Erase Fault Data History. This fault can be caused by a number of things, including wasps' nests, dirty burner, etc. All of these will need to be checked on ours, however, at least for now we're running on A/C power and the food (and beer!) will stay cold.

Hope it helps one of you someday. I removed the stuff blocking the fins before Paul did the reset, and he checked for wasps' nests, etc, before he did the reset. Working ok for now.
