Étapes pour vérifier le problème :

  1. If you know which product you have, specific ice maker troubleshooting is available by product line. Refer to:
  2. ​​After turning on the product and the ice maker, wait 24 hours for ice production. It may take this long to see ice cubes in the ice bin since the freezer must first cool to temperature, then the ice cubes form and drop into the bucket.
  3. Verify the ice maker is turned on. See specific product instructions below or the Use and Care Guide for turning the ice maker on or off:
  4. Warm freezer temperatures impact ice maker performance. Confirm the freezer temperature is at or below 5°F. Sub-Zero recommends 0°F freezer temperature setting.
  5. If the freezer temperature is higher than 5°F, see Warm Freezer Troubleshooting.
  6. Clean the condenser if it was not cleaned in the past 6 - 12 months. See Clean the Condenser for instructions.
  7. Reseat the water filter on the product if one is present. Turn power off, remove the water filter, and install the filter again. See how-to information for your specific filter:
  8. If an inline home water filter is installed, see if the filter expired or needs replacement. See Inline Water Filters. See also, Sub-Zero Does Not Have a Water Filtration System.
  9. Confirm good water pressure to the unit. See How to Confirm Water Pressure.
  10. Make sure the ice bin is properly installed by making sure it is level and seated in place. On some models, the ice bin presses the ice maker switch. This varies from model to model.
    • If the bucket is jammed, defrost the area around the bucket with a hair dryer and remove.
  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 turned on. Refer to Water Line Shut-Off Valve Location for details. Examples shown are in the OFF position.

  14. Verify 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.
  15. Verify the ice maker water fill tube is not blocked. See Ice Maker Fill Tube Frozen.
  16. After freeing obstructions, 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. Let 24 hours pass, then check for ice cubes in the ice bin.
  19. If these troubleshooting steps do not resolve the issue, service is necessary to expertly diagnose and repair the product. Contact Factory Certified Service to schedule an appointment for repair.
