Whirlpool Refrigerator Ice Maker Assembly (W11284458) (Replaces W11088559)

The icemaker is a self-contained unit inside your side-by-side refrigerator that automatically produces and harvests ice by filling a mold with water, freezing it, and then ejecting the cubes into the storage bin. It uses a built-in thermostat and motor to cycle through each stage, working with the refrigerator's water supply and temperature controls to keep a steady supply of ice ready for use.

Important Compatibility Note: Part number W11284458 is the current manufacturer-approved replacement for the following discontinued part number(s): W11088559. If your appliance documentation or old part uses any of these numbers, this is the correct, updated component for your repair.

Icemakers can fail from a worn-out harvest motor, a faulty thermostat that can no longer sense when the mold is frozen, or mineral buildup from hard water that jams the ejector blades over time. Electrical faults, a cracked mold, or a broken shutoff arm can also cause the unit to stop cycling or overfill the bin.

These symptoms can point to an icemaker that may need to be replaced:

- Refrigerator stops making ice entirely

- Ice maker runs continuously and overfills the bin

- Ice cubes come out small, misshapen, or partially formed

- Loud buzzing, clicking, or grinding sounds during the ice cycle

- Water fills the mold but ice is never ejected into the bin

- Ice has an unusual taste or odor coming from the mold area

- Icemaker unit is visibly cracked or has a broken shutoff arm
