  • How to adjust temperature setting on 200 or 300 Series unit

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

  • The higher the number, the colder the temperature.
  • Sub-Zero recommends setting the dial between 4 and 6 for the optimum temperature.
    • This setting produces temperatures near 38°F in the refrigerator and 0°F in the freezer.
  • If the numbers are worn off or not on the unit, turn the dial counterclockwise to turn the unit warmer or off and clockwise to make the unit colder.
  • 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 each compartment.
