This is just outboard of the watermaker. It's the microwave. Under the rear, is the piping for the refer and freezer. The system is operating. (frosty) A cover for the piping is on the 'to do' list. When I first built this system back about 1990, I installed the refer thermal expansion valve (TXV) inside the refer box. You needed a mirror to see it. The freezer TXV was behind the box at the bottom, incapsulated in foam insulation. Dumb, and dumber. This time they share the same space under the microwave and are easy to reach if needbe. That's the refer TXV that's seen frosting.
