Customer Questions and Answers for Refrigerator Ice Maker Assembly by Whirlpool

John, You will want to check the fill tube to make sure that the fill tube is not frozen. If it is frozen the water valve would need to be replaced. If the fill tube is not frozen they the water valve would need to be checked to see if voltage is getting to it. If there is power to the water valve when the icemaker calls for water then the water valve would need replaced. If there is not power then replace the icemaker.
