With serial 1363645, your 1200LRIMSS is in the 832172–8981138 range. The board kit for that range (633299) is discontinued, but the rear power board is still available as the Norcold 621271001 power board or the upgraded Dinosaur 6212XX. If the front optical board has failed, the Norcold N15DCSS is the replacement fridge.
