Built-In Series Sabbath Mode

Core Issue:

  • SAb on the control panel of a Built-In refrigerator
  • What features will disable during Sabbath mode?
  • How is Sabbath mode set in a Built-In (BI) Series product?
  • On a dispenser model, will the dispenser be disabled during Sabbath mode?
  • What does SAb displayed on the control panel indicate?
  • Why is SAb displayed on the control panel, and the lights not working?
  • Can Sabbath Mode be left on all the time?


While in Sabbath mode, the Built-In (BI) Series Sub-Zero will disable the lights, ice maker, door alarm and dispenser.

  • SAb displayed on a Sub-Zero control panel indicates the Sabbath mode is activated.
  • There is no harm in leaving the unit in Sabbath Mode.
  • See Use and Care for more information. For additional information on Sabbath mode, see Star-K.

To enter Sabbath mode on a BI Series product:

  1. While power is turned on, touch the POWER button on control panel.
  2. "OFF" appears in the display.
  3. Touch and hold POWER for 10 seconds until "SAb" appears.
  4. To return to normal operating conditions, touch POWER.

If these steps do not resolve the issue, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair.
