General Temperature Setting Information

Electronic Control Panel Display

The temperature range in a Sub-Zero with an electronic control panel is 34° - 45°F (1° - 7°C) degrees in the refrigerator and -5° to 5°F (-20° to -15°C) degrees 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 as they cover most foods.
  • Wine Storage products have different temperature ranges to preserve wine, see Wine Storage Temperature Range.
  • 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.

Adjust the Temperature

For Designer (formerly Integrated) Refrigeration and Designer Wine Storage models, see Designer Series Temperature Adjustment. For 400, 600, 700, Classic (formerly Built-In), UC Undercounter, and 648PRO:

  1. Press the colder or warmer key for the desired refrigerator or freezer section.
  2. For units that have a "zone" feature, select the desired zone and press the colder or warmer key.
    • Unit normally shows the actual temperature.
    • When the colder or warmer key is pressed, unit will show the set temperature.
  3. After setting to desired temperature, display will return to actual temperature after 3 seconds.
  4. The temperature change is not immediate. Allow 24 hours for the unit to reach the set temperature. An audible beep occurs during this operation.

Dial Controls

200, 300, and 500 Series models with dial control thermostats:

  1. In units with a dial control, set the dial between 4 and 6.
    • 1 is warmest setting and 10 (or 7 on some models) is coldest.
    • Setting the dial from 4 to 6 will produce temperatures near 38°F in the refrigerator and 0°F in the freezer.
  2. For instructions on adjusting the setting, see:
