Answer Hello Amy. Cycle the ice maker and see if there is power coming to the water valve, and if the fill tube in the freezer is frozen. If there is power and the fill tube is clear, you will need to replace the water valve WP67005154. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter.
