Temperature Adjustment

The 200 and 300 Series temperature control knob has numbers on it, either 1-7 or 1-10 depending on production date.

  • The higher the number on the knob, the colder the temperature.
  • Sub-Zero recommends setting the dial between 4 and 6 for the best temperature.
    • This setting produces temperatures near 38°F in the refrigerator and 0°F in the freezer.
  • To turn a section off, rotate the control down past number 1. It will click and turn off.
  • Temperature controls are at the top left of the compartment.

Temperature Knob Location

  1. Place a hand on the back wall of the unit near the top.
  2. Run along the upper right and upper left corners until the control is located.

Numbers Missing on Knob

If the numbers are worn off or not on the unit:

  • Turn the dial clockwise to make the unit colder.
  • Turn the dial counterclockwise to turn the unit warmer or off.
