    * Original 700 Series units do not have an Ice ON/OFF key. The ice maker is turned off by removing the ice bucket.

    Note: When the ice maker is turned on, water may not flow into the mold immediately.

    1. Verify service messages, icons, or error codes are not displayed. If so, resolve them. If "Service Ice" is flashing, the water valve was energized longer than fifteen seconds, and the ice maker system is disabled. See also:
    2. Confirm freezer temperature is at or below 5°F. Warm temperatures affect ice maker performance.
    3. Verify the condenser is clean. See Clean the Condenser for details.
    4. Change water filters as often as recommended, typically every 6-12 months (Built-In, Integrated, and PRO48).
    5. Ensure the ice bucket is properly installed. It must make contact with the switches behind it to operate. In Over/Under and Drawer models, the bucket or basket engages the ice maker switch when the drawer is closed.
    6. Ensure ice maker shut-off arm is in the down position.
    7. Ensure the ice maker white plastic rudder arm is attached to the shut-off arm and reattach if needed. If broken or cracked, replace the ice maker shut-off arm.
    8. Verify water supply to the unit is turned on. Refer to Water Line Shut Off Valve Location for details.
    9. Ensure the ice maker is free of obstructions or jammed ice cubes. Use a hair dryer aimed toward the fill tube and ice mold on low for 5-10 minutes to free stuck ice cubes.
    10. Verify ice maker water fill tube is not obstructed. See Ice Maker Fill Tube Frozen.
    11. After freeing obstructions, turn the unit off and then on again to reset.
    12. If ice production stops often with the use of a reverse osmosis system or well water, a pressure booster or regulator may improve performance. Contact the reverse osmosis provider or speak with a plumber for suggestions.
    13. Reseat the water filter (if present) by removing and reinstalling it. See Remove Water Filter for instructions.
    14. Reset the water filter if applicable. See also:
    15. Let 24 hours pass and check for ice production.
