Quick answer

Common recommended settings are 38°F for the Sub-Zero refrigerator and 0°F for the freezer. Long-term wine storage is commonly around 55°F. Verify with a separate thermometer, allow 24 hours after any change, and call for service if actual temperatures don't match the display.

How to Verify

  1. Place a thermometer in a glass of water on a middle shelf.
  2. Wait 24 hours without frequent door openings.
  3. Compare to the display.

A large mismatch can mean a failing thermistor.
