Whirlpool Excessive Water Fill / Long Freeze Cycle

Whirlpool undercounter ice maker makes oversized or fused-together ice slabs

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Misadjusted water level float, sticking water inlet valve, failed evaporator thermistor, control board timing fault

Safety: Disconnect power and shut off water.

Check water level: Inspect the reservoir during fill. If it rises too high, adjust the float per Whirlpool instructions so the level stops at the correct mark.
Test inlet valve for seepage: With power off and water on, watch for slow dripping into the reservoir. Replace the valve if it leaks.
Verify freeze time: If the unit freezes too long before harvest, test the evaporator thermistor and replace if out of spec.
