If your refrigerator is making discolored or dirty ice or your ice maker is not working properly, start with the most likely causes. The water supply tube to the ice maker is the top suspect when tubing sat unused or was disconnected for months and has become stained; replace the tubing if it looks discolored. Next check the ice maker assembly and tray for a worn or corroded coating that flakes into the cubes and replace the icemaker if the tray is deteriorating. Less commonly dirty ice comes from temporary contamination in the house water supply after a main break or hydrant flush, so discard the old ice and run the cold faucet until the water clears. Uncommonly, residue from an old water filter can shed material into the ice, so swap the filter every six months and replace it if you suspect media shedding.

01 - Tappan Refrigerator Water Supply Tube
During normal use the water supply tubes will have water flowing through them keeping them clean. If the water supply gets disconnected or water is left in the tube and not used for 6 to 12 months, it can become discolored. If the water at the other faucets in the house is ok and you have replaced the water filter you may need to replace the water tubing to the ice maker to resolve the issue.

If the icemaker tray has a coating, the coating may be wearing off. If you are getting pieces or chunks of material stuck in the ice, check the ice maker tray. If the coating on the tray is corroded and flaking off, replace the icemaker.
A fire hydrant that was flushed or a broken water main can cause dirty water to enter the home. Since the ice maker uses the same water supplied to the kitchen or bathroom faucets, dirty water can discolor the ice. Discard the old ice and run the water for awhile at the kitchen or bathroom faucet until the water clears up before having the ice maker make new ice.
