Customer Questions and Answers for Refrigerator Ice Maker Kit by Whirlpool

John, if the ice maker WPW10190965 is not overfilling and is leaking through the tray, it would need to be replaced. However, if it is overfilling, the fill tube would need to be inspected for signs of the fill valve W10408179 leaking by. If it is not showing signs of leaking by, the ice maker will need to be put into a harvest mode by jumping the ice maker module terminal H to terminal T. Once the ice maker clicks, the jumper would need to be removed and the harvest observed. Once the ice maker fills with water, it should only fill for 8 seconds. If the valve is supplied voltage for more than 8 seconds, the ice maker has failed. If the valve continues to supply water after voltage has stopped, the valve has failed.
