I have discovered green bluish flakes of minerals, or something, coming out of the water supply that flows into an Amana refrigerator model SRD20S4W. See video of it here: http://www.youtube.com/watch?v=nMX2Fb794q0&feature=youtu.be I discovered this stuff when I was troubleshooting a leak from the freezer. The leak was dribbling out between the freezer and the freezer door seal, onto the floor. When the problem first occurred, I thought the water inlet valve on the Amana refrigerator was shot, so I replaced it. I noticed some of those green bluish particulates at that time, but I didn't think it warranted any concern. It was a small amount of greenish particulate and I (naively) assumed it was normal sluff from old copper tubing and brass fittings. Some days later, the leaking problem occurred again. I turned off the water supply to the fridge/freezer and put that repair on my back burner. We don't use the water from the fridge, and we could buy ice for a few weeks. Low and behold, some weeks later, the leak began to dribble again. Puzzled, I discovered that I had a large amount of ice damming up the drain to the evaporator pan. I have now removed everything from the fridge and freezer and have thoroughly thawed and cleaned the entire unit. Does anyone know what the green bluish flakes are, that are flowing from my water supply, when I turn it off and then back on again?
