Used to have a Micro Minnie with a Dometic DMC-4101 12volt refrigerator. Short story is that we had some issues with consistent cooling, so I bought a spare control board. We sold our trailer, so I don't need the board any longer. Might work for other models as well, but you would have to determine that. This is a new, unused control board. It is the upgraded version.
