Product review (5 stars): Whirlpool Gold Ice-Maker
Worked perfectly and fixed the issue on Whirlpool Gold (2011 unit). The problem: Ice maker stopped working. Possible root causes learned over trial and error in order of lowest to highest cost and ease of replacement:  Replaced water filter (clogged filter can cause ice maker to not fill). Replaced Ice level Control Board Kit (If light doesn't blink when interrupted, it's control board). Replaced ice maker unit (Replaced because coating on the ice mold deteriorated and small chips of the coating was showing up on ice cubes. Didn't replace water pump yet. Water and ice maker working now.
Ease of removal and installation: Easy
