Whirlpool Ice Maker Water Pump (1901A)

The Whirlpool Ice Maker Water Pump moves water from the reservoir up to the freezing tray where ice cubes are formed. It uses a small motor to circulate water over the freezing plate in a continuous flow, which helps produce clear, evenly shaped ice during each cycle.

The Whirlpool Ice Maker Water Pump can fail from mineral buildup inside the pump body, wear on the internal motor or impeller, or damage caused by running dry without water. Exposure to hard water over time can clog or corrode pump components, reducing flow or stopping water circulation entirely.

Watch for these symptoms to help determine if the water pump is the source of your ice maker problem:

- Ice maker produces little or no ice despite water supply being connected

- Ice cubes are hollow, thin, or poorly formed

- Unusual humming, buzzing, or grinding noise coming from the ice maker

- Water not circulating over the freezing tray during the ice making cycle

- Ice maker runs through cycles but the tray stays dry

- Visible mineral deposits or corrosion on or around the pump

- Ice production slows significantly over time without any other clear cause
