Electronic Control Panel Display Temperature Ranges

The temperature range in a Sub-Zero with an electronic control panel is 34° - 45°F (1° - 7°C) in the refrigerator and -5° to 5°F (-20° to -15°C) in the freezer.

  • In units with an electronic control panel, the factory settings of 38°F (3°C) in a refrigerator and 0°F (-18°C) in a freezer are ideal food storage temperatures.
  • Wine Storage products have different temperature ranges to preserve wine, see Wine Storage Temperature Ranges.
  • Setting the temperature higher or lower than factory settings causes the unit to run more or less, according to set temperature.
  • It is not possible to set a temperature higher or lower than the range listed above.
  • If the control panel does not respond, refer to Sub-Zero Electronic Control Panel Non-Responsive for troubleshooting steps.

The steps to adjust the temperature vary depending on the product family.
