The 637779 is for the N621/N821, not the 1200. With serial 1122113, your 1200LRIM is in the 832172–8981138 range. If you need the rear power board, use the Norcold 621271001 power board or the Dinosaur 6212XX. The front control panel (optical board) for the 1200 is discontinued, so if that's what failed, the Norcold N15DCSS is the replacement fridge.
