Whirlpool Whirlpool WRT318FZDW 18 cu. ft. Top Freezer Refrigerator MECH-ICE-MAKER Error Fix: Ice Maker Not Making Ice

Error code MECH-ICE-MAKER on the Whirlpool Whirlpool WRT318FZDW 18 cu. ft. Top Freezer Refrigerator means: Ice Maker Not Making Ice. The ice maker is not producing ice. Check in order: (1) Is the ice maker turned on? The bail arm or switch should be in the ON position. (2) Is the water supply connected and turned on? Check the shutoff valve, typically behind the refrigerator or under the kitchen sink. (3) Is the water inlet valve working? Listen for a brief buzzing sound every 1-2 hours (the fill solenoid). (4) Check the water filter — a clogged filter reduces flow to the ice maker. Replace the filter if it has been more than 6 months. (5) Is the freezer cold enough? The freezer must be at 0°F or below for ice production. (6) Check the ice maker module — on Whirlpool models, press the test button (usually requires a thin object) and listen for the motor to cycle.
