PRO48 Sabbath Mode

Core Issue:

  • What features are disabled during Sabbath mode?
  • How is Sabbath mode set in a PRO48 product?
  • 648PRO Sabbath mode

Steps to Verify Issue:

To enter Sabbath mode on a PRO48 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.
  4. Four audible chimes indicate Sabbath mode has been initiated.
  5. To return to normal operating conditions, touch Power twice.


While in Sabbath mode, the PRO48 Series Sub-Zero disables the external displays, lights, ice maker, and door alarm.

  • There is no harm in leaving the unit in Sabbath mode.
  • See the Use and Care Guide for more information.
  • For additional appliance Sabbath information, see the Star-K website.
