I have the same question about my 2015 Miramar 32.1. The refrigerator makes no ice, and I suspect that there is no water getting to the back (?) of the fridge. I looked through the wood grate under the fridge, and in the panel outside behind the fridge, but no sign of a water connection of little valve. The fridge is equipped with an icemaker, but possibly not implemented in this Miramar, as I don't see any water line to it.
