  • Are Sabbath Mode kits installed under warranty?


Most Sub-Zero and Wolf models with electronic control panels have a Sabbath Mode when sold.

  • Sabbath Mode turns off the lights, ice maker system, and door alarm and prevents them from turning on again while the unit is in Sabbath Mode.
  • Normal cooling and heating operations will still take place.
  • In the event of a power failure, when power returns, the unit will return to this mode.
  • For additional information, refer to Sub-Zero Sabbath Mode or the product Use and Care Guide.

Star-K compliance requires more strict adherence to Star-K guidelines; some products may require a kit to make the product Star-K compliant.

  • For Classic (BI) series, Designer (IT, IC, ID) series, and 648PRO series, Star-K compliant Sabbath Mode is a standard feature and does not require a kit.
  • Visit for the most up-to-date listing of Star-K compliant appliances and requirements to meet Star-K standards.
  • If a unit falls before the serial breaks provided on the Star-K website, the unit has Sabbath Mode but is not Star-K compliant and a kit is not available to change this.
  • Installation is not covered under warranty.

Sub-Zero recommends that the Star-K Sabbath Mode kit be installed by a service technician. Contact Factory Certified Service to schedule an appointment for repair.
