When the freezer gets cold but the fridge section stays warm, that's the classic sign of a cooling unit that's getting weak, not a board problem. The freezer plate gets cooled first, and a tired unit can't push enough cold down to the fridge fins. Before you replace anything, make sure the RV is level, the back vents are clear, and the fins aren't iced over. If those all check out, the Nordic 3381A cooling unit is the replacement for the N821, and it's in stock.
