Before you replace the board, check the AC fuse on the board and test the AC heater. It should read resistance, and an open reading means it's burned out. The 618872 AC heater fits all 1200s. If the heater and fuse are good, then it's the board. For serial 1136824, that's the Norcold 621271001 power board or the Dinosaur 6212XX.
