Sub-Zero Refrigerator Not Making Ice Guide

In most instances, a Fix Sub Zero Ice Maker can be resolved with a simple adjustment or DIY fix. Our troubleshooting guide details how to determine the most likely reasons for a lack of ice and the right solutions.

Step 1: Check the Controls

Make sure that the ice maker is turned on and that the freezer is at the proper temperature. If the ice maker is off, it won’t receive power to make ice. When the freezer temperature is too high, it may be too warm for ice to form or stay frozen.

Here’s how to check the ice maker and freezer temperature via the controls:

  • Make sure the ice maker is turned on: A single or triple cube icon will appear on the refrigerator’s display if the ice maker is on. If the icon isn’t visible, press the ICE MAKER button to turn it on.
  • Check the freezer temperature: Sub-Zero recommends setting the freezer temperature at 0℉ for optimal ice production. If the refrigerator’s display shows a higher temperature despite this setting, make sure the freezer door is properly closed. If warm freezer temperatures persist, you may need to clean the condenser coils or consult a professional service.

Step 2: Check the Water Filter

Without regular changes, the refrigerator water filter can become clogged with contaminants, restricting water flow to the Fix Sub Zero Ice Maker. Sub-Zero recommends changing the water filter every 6-12 months to prevent clogs that restrict water flow and ice production.

Improper filter installation can also limit water flow to the ice maker. When you find your Sub-Zero refrigerator not making ice, remove and reinstall the filter even if it’s been recently changed. Refer to your user guide for instructions on how to install a filter on Classic Series models.

Step 3: Check the Water Line & Pressure

Low water pressure or a water line that’s not turned on can also restrict water flow to the ice maker. Either of these two factors can result in a Sub-Zero refrigerator not making ice due to a limited water supply.

These tips detail how to assess your refrigerator’s water pressure and water line:

  • Water pressure: The correct water pressure varies depending on your model refrigerator. If you suspect your home has low pressure and it can’t be adjusted higher, a plumber can provide a professional assessment.
  • Waterline: Make sure that the water line valve is turned on so water can flow to the refrigerator from your home supply. The valve may be behind the unit, in a cabinet under the sink, or in your home’s basement.

Step 4: Inspect the Ice Maker

If you still find your Fix Sub Zero Ice Maker ice after the above assessments, you may need to inspect the ice maker. Various ice maker components may require adjustments or replacements to function properly.

Here’s how to inspect the ice maker:

  • Check the shut-off arm: The arm must be in the down position for the ice maker to be on and producing ice. If the arm is broken or cracked, it requires replacement.
  • Make sure the ice bin is correctly installed: The bin must be level and secure to enable ice production.
  • Look for ice jams: If ice jams the ice maker’s components, cubes won’t be able to fall into the ice bin. The freezer may require a manual defrost to melt accumulated ice.
  • Look for a frozen fill tube: Water flow is restricted if the fill tube that supplies the ice maker freezes. If the fill tube is frozen, it should be assessed by a Sub-Zero refrigerator repair service.
