Sub-Zero Ice Maker Makes Too Much Ice


  • Ice maker producing too much ice
  • Ice bin overflowing with ice
  • Ice maker will not stop making ice
  • Ice falls out of drawer or bin
  • Too much ice production
  • Sub-Zero making too much ice


The ice maker will make 8 cubes of ice every 2-3 hours on average.

  • The ice bin may take 1-2 days to fill completely.
  • All ice makers can be manually turned off by manually raising the ice level arm (rudder) to the "up" position. Simply removing the ice bin will not suffice. Refer to Turn Ice Maker On or Off for product-specific instructions. 
  • If the unit is overproducing ice, there may be something wrong with this functionality.

If too much ice is produced:

  1. Make sure the ice bin is properly installed.
  2. If available, verify the Max Ice feature is not enabled. Max Ice increases ice production for a 24-hour period.
  3. Make sure ice maker shut-off arm is attached to the ice maker.
  4. Make sure ice maker rudder arm is attached to the shut-off arm.

  6. If these steps do not resolve the issue, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair.
    • The same troubleshooting applies if the ice bin is overflowing or ice cubes are falling out of the ice bin.

Refer to the product Use and Care Guide for further information.
