Customer Questions and Answers for Refrigerator Ice Maker Assembly by Whirlpool

Hello Marc, and thank you for your question.

The first step would be to verify that the freezer is reaching a temperature below 10°F using a thermometer. If the temperature checks out, the issue could be with either the ice maker or the optical sensor system.

This model uses an optical sensor on the right side wall of the freezer that detects whether the ice bin is full and also controls the power going to the ice maker. If the sensor detects a full bin—or if something is obstructing the sensor—it will prevent voltage from reaching the ice maker.

Check that the shutter on the sensor is in the “on” (or open) position. Then tape open the flapper door on the opposite side to ensure a clear line of sight between both optical sensors.

With the line of sight clear, check for 120V AC between the black and white wires going to the ice maker.

If you get 120V AC, then the ice maker W11512152 has failed.

If no voltage is present, the optical sensor board W11629974 is likely the issue.
