#506's Factory all electric refrigerator quit getting cold last year. It is a Norcold Dual Electric model DE-728, still makes noise but does not get cold. Has anyone had any luck repairing/bringing back from the dead these old refrigerators? I am not a fan of the 3-way 'Absorbtion' type refrigerators so I am sticking with the dual electric (continues to work while under way). Rather than buying a new one (cost prohibitive) I am going to at least try to fix this one. Does anyone have an old one for spare parts laying around? I need the compressor off the back and the inverter from underneath. Any information like a service manual or refrigerant specifications (type and amount) would be a big help also. 

Thanks
