Ice maker
error codes,
read properly.

The ice maker asked for water and got too little, too slowly or none at all, or water kept arriving after the fill should have ended. A closed shutoff, a kinked line, a clogged filter and low house pressure are ruled out before the water inlet valve is replaced or the fill tube is thawed. If water is on the floor, close the supply valve before reading anything on the display.

No Ice Coming From the Ice MakerIce Maker Making Small or Hollow CubesIce Maker Fill Tube FrozenIce Maker Leaking on the Floor

The ice maker froze a batch and could not release it, or the harvest never started: the ejector arm or the twisting tray stalled, the mold heater did not loosen the cubes, or the arm that senses a full bin reported the wrong thing. Ice jammed against the arm and a bin pushed in crooked are cleared first; a motor module or a whole ice maker assembly comes after.

Usually leads to

The control lost track of how cold the ice mold or the ice compartment is, because a thermistor reads nonsense or its wire lost contact. Without that reading the ice maker cannot tell when a batch is frozen, so it stops or harvests at the wrong time. Frost packed around the sensor and a loose plug are checked before the sensor itself is changed.

The fan that moves cold air to the ice maker stopped, slowed or froze in place. A door ice maker depends on that air, carried to the door through a duct, so when the fan quits the ice compartment warms and cubes melt and refreeze into clumps. Ice blocking the blades or the duct is ruled out before a motor is ordered.

The dispenser was asked for ice and could not deliver it: the auger motor stalled against a frozen block, the flap at the bottom of the chute stayed shut, or the paddle switch never told the control it was pressed. Emptying the bin and thawing the chute come before the auger motor, the door flap solenoid or the switch is replaced.

Ice Dispenser Not WorkingIce Clumped or Frozen in the BinIce Maker Making NoiseIce Maker Error Code

An undercounter ice maker could not get rid of its meltwater or its rinse water: the drain pump did not run, its float stuck, or the drain line is blocked, kinked or frozen. Water backing up inside can spill onto the floor, so the water supply is closed before anything else, then the line and the pump are cleared or replaced.

The boards that run the ice maker stopped hearing each other, or one of them failed: the main control lost contact with the dispenser panel or the ice maker module, or a board reported an electrical problem of its own. Water that dripped onto a connector and a loose harness are checked before a board is ordered by model number. If the ice maker keeps tripping the breaker, leave it off until the visit.
