Review product-specific troubleshooting:

- Designer (IT, IC, ID) Refrigeration Control Panel Does Not Work
- Designer Wine Series (IW) Control Panel Does Not Work
Check the Electrical Supply
- Verify power is supplied to the unit.
- Reset the unit's electrical supply at the circuit breaker for 30 seconds and retest.
- Verify the unit is not connected to a tripped GFCI.
- If accessible, test the electrical outlet that the unit is plugged into.
Check the Unit Settings
- Verify that the zone is not turned off. If the zone is off, double dashes (--) on the control panel will appear. See Double Dashes (--) on Control Panel.
- If lights are out in the unit, the control may appear non-responsive as the display panel is backlit. See Sub-Zero Control Display Is Dark.
- Verify the unit is not in Sabbath Mode. See Sub-Zero Sabbath Mode and Star-K Information.
- For drawer units with a separate control for the drawer section, make sure the wire harness (communication cable) is securely plugged in the back of cabinet behind the drawer.
- If the control panel is still non-responsive, regardless of whether the refrigerator is running, service is necessary to expertly diagnose and repair the product. Contact Factory Certified Service to schedule an appointment for repair.
