Display shows Sb (Sabbath mode); interior lights and some functions appear disabled, but cooling continues.

Note: Sb is not a failure code; it indicates Sabbath mode is active.

Steps to exit Sabbath mode:

• 1. Consult user manual: Different Frigidaire models use different button combinations. Commonly, press and hold the Freezer Temp and Refrigerator Temp buttons together for 5 seconds.
• 2. Try alternate combination: On some models, press and hold the Power Cool and Power Freeze buttons or the Alarm and Down buttons for several seconds.
• 3. Confirm exit: The display should return to showing temperatures and interior lights should function normally.

If Sb remains and normal controls are not restored, the user interface board may be malfunctioning and require service.
