Adjusting Whirlpool Modular Ice Makers

Whirlpool modular ice makers produce ice cubes in a crescent shape. The amount of water that fills the ice cube tray determines the size of the ice cubes. Water pressure varies from home to home so that the factory normal setting on the ice maker will not produce the same size ice cubes in every instance. This type of ice maker needs adjustments in the water fill time to increase or decrease the size of ice cubes.

Most modern refrigerator freezers include an icemaker.
  1. Turn the small adjustment screw on the side of the Whirlpool modular ice maker with a Phillips screwdriver to adjust the water level.
  2. Turn the adjustment screw clockwise to decrease the amount of water that fills the ice tray per cycle. If the ice cubes are too large and the water overflows, they freeze to the tray and will not eject properly. Decreasing the water fill level will correct this action.
  3. Turn the adjustment screw counterclockwise to increase the water fill level. This will enable more water to enter the tray and make larger ice cubes. Increase the water fill level if ice cubes are small or contain a hollow center.

Things You Will Need

  • Small Phillips screwdriver


  • Adjusting the water fill level by 1/2 turn in either direction increases or decreases the total water by 20 cc's and 1.2 seconds of filling time.
  • Adjusting the water fill level by one full turn in either direction increases or decreases the total water volume by 40 cc's or 2.4 seconds of filling time.
  • Whirlpool modular ice makers are factory preset at a normal water level of 7.5 seconds of fill time. This level shows as a small hole centering inside of the large hole on the front of the ice maker at the adjustment screw level.


  • Do not turn the adjustment screw more than one full turn in either direction from the normal setting. This action can damage the ice maker.
