Whirlpool Refrigerator Ice Maker (WPW10277450)

The Whirlpool Refrigerator Ice Maker is the self-contained assembly responsible for producing and harvesting ice inside your refrigerator's freezer compartment. It monitors freezer temperature, fills with water, freezes it into cubes, and then ejects them into the ice bin through a motor-driven cycle. The assembly includes the mold, heater, thermostat, and ejector components needed to complete the full ice-making process.

The Whirlpool Refrigerator Ice Maker can stop working due to a failed thermostat or mold heater, a burned-out ejector motor, or internal components that wear out over time from repeated freeze and harvest cycles. Water mineral deposits, power fluctuations, or a freezer that runs too warm can also accelerate wear and cause the assembly to stop producing ice reliably.

Look for these symptoms to help determine if the ice maker assembly needs to be replaced:

- Refrigerator produces no ice at all despite water supply being connected

- Ice maker runs through cycles but does not eject cubes into the bin

- Ice cubes are hollow, misshapen, or much smaller than normal

- Ice maker fills with water but never freezes or harvests

- Unit makes unusual clicking, humming, or grinding sounds during a cycle

- Ice bin remains empty even though the ice maker arm is in the down position

- Water overflows the mold and freezes in the bottom of the freezer
