An ice maker can stop producing because the freezer is too warm, the water supply is off or weak, the filter is restricted, the shutoff arm or sensor is in the stop position, or ice is jammed. Before taking anything apart, confirm temperature, controls, and accessible water flow.
Confirm that the freezer is cold enough
A freezer that barely keeps food hard may not reach the temperature the ice maker needs to cycle. Use an appliance thermometer and solve any general cooling problem first.
Check the ice-maker switch, arm, or sensor
During cleaning or loading, the control can be switched off or obstructed. Confirm the manual-specified position and clear cubes that prevent the arm or sensor from reading the ice level correctly.
Check the water supply and filter
Make sure the accessible supply valve is open, visible tubing is not kinked, and the filter is not overdue. A slow water dispenser can be a clue to a shared water restriction.
Humming without water or leaks need service
An inlet valve, frozen line, or internal mechanism can fail. Do not use high heat or sharp tools to thaw tubing; if there is a leak or the unit repeatedly tries to fill without water, arrange service.
