Designer (Formerly Integrated) Series Does Not Make Ice

Cause:

  • Possible jammed ice cube
  • Low water pressure
  • Frozen ice maker fill tube
  • Warm freezer temperature
  • Water valve energized longer than fifteen seconds
  • Ice bin not in place

Topics:

  • Designer (formerly Integrated) refrigeration unit not making ice
  • Designer ice maker not working, does not work
  • No ice production
  • Frozen fill tube

Steps to Verify Issue:

  1. After the unit is on, wait 24 hours for ice production. It may take this long to see ice cubes in the ice bin.
  2. Verify the ice maker is on. See How to Turn Designer (formerly Integrated) Ice Maker On or Off for instructions.
    • In the Options menu, ice cube(s) are highlighted if on.
  3. Make sure the door or drawer has opened and closed recently.
    • If the ice maker cycles 20 times without the door opening and closing, it automatically turns off.
  4. Warm temperatures impact ice maker performance. Confirm the freezer temperature is at or below 5°F. Sub-Zero recommends 0°F freezer temperature.
  5. If the freezer temperature is higher than 5°F, see Warm Freezer Troubleshooting.
  6. Verify the condenser is clean. See Clean the Condenser for instructions.
  7. Change water filters as often as recommended, typically every 6-12 months.
  8. If installed, verify the home inline water filter is not expired. See Inline Water Filters.
  9. Confirm good water pressure to the unit. See How to Confirm Water Pressure.
  10. Make sure the ice bin is properly installed by verifying it is level and seated in place. On some models, the ice bin presses the ice maker switch. This varies from model to model.
  11. Verify ice maker shut-off arm is in the down position.
  12. Verify 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.
  13. Make sure the water supply to the unit is on. Refer to Water Line Shut-Off Valve Location for details.
  14. Verify the ice maker is free of obstructions or jammed ice cubes. Use a hairdryer aimed toward the fill tube and ice mold on low for 5-10 minutes to free stuck ice cubes.
  15. Verify the ice maker water fill tube is not blocked. See Ice Maker Fill Tube Frozen.
  16. After freeing any blockages, turn the unit off, then on again to reset.
  17. 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.
  18. Reseat the water filter (if present) by removing and installing it. See Remove Water Filter for instructions.
  19. Reset the water filter if a water filter is present.
  20. Let 24 hours pass and check for ice production.
