My husband and son found this adorable antique mini fridge at a yard sale. They brought it home and started it up and it cooled beautifully. Then they tried to move it. Something leaked out of the back when they tried to bring it up to the back porch. The boys guess that it was coolant, but aren't sure where it leaked from. Does anyone have a schematic or has anyone worked on these? I have also been told that some have different versions of coolant. Any information is very much appreciated! I do have photos, but cannot seem to get them to upload. There is a small freezer piece inside the upper right hand, it is curved with a lever handles and the largest component on the back mechanical area is like a flattened sphere with a zig-zag coil around it. Hope that helps!
