I have a Frigidaire FRT18IL6DMP (mfd 10/07). This model has the automatic ice maker, and the ice cubes have had a funny taste from day one. I have tapped into the water supply from under the kitchen sink. I used refrigerant copper from the supply to behind the fridge, then it couples one of the flexible woven stainless steel supply lines to the fridge. Although I do have city tap water, it tastes fine normally. When the ice cubes melt in my drink, they leave a very funny taste. I thought eventually this taste would go away as water moves through the lines, but that hasn't happened yet and it has been more than 6 months since we got the fridge. Granted, we don't move a whole lot of ice in my house, but I have dumped the entire tray of cubes several times and let it start over. The cubes do not seem to lose the weird taste. Could it be the plastic line that runs from the bottom of the fridge up to the ice maker? Is there a way to disconnect this at the actual ice maker and just let a steady flow of water run blast through it for a while to clean it out? Any advice would be appreciated.
