Topics:

• Ice maker not making enough ice
• No ice production
• Ice maker not working with the ice bin removed
• Ice maker troubleshooting
• Ice maker does not make ice or ice maker does not start

Cause:

• Possible jammed ice cube
• Low water pressure
• Frozen ice maker fill tube
• Warm freezer temperature
• Water valve energized longer than fifteen seconds

1. 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.
2. Verify the ice maker is turned on.
3. Make sure the water supply to the unit is turned on.
4. Warm freezer temperatures impact ice maker performance. Confirm the freezer temperature is at or below -15 °C. Sub-Zero recommends -18 °C freezer temperature setting.
5. If the freezer temperature is higher than -15°C, Contact Factory Certified Service to schedule an appointment for repair.
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.
8. Make sure that 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.
9. Verify ice maker shut-off arm is in the down position.
   • Turn the unit off, and if the arm is up, push down gently. The ice maker arm only moves an inch. Please handle carefully.
10. Verify the ice maker water fill tube is not blocked.
11. After freeing obstructions, turn the unit off, then on again to reset.
12. Let 24 hours pass, and then check for ice cubes in the ice bin.
13. 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.
