Frequently Asked Questions

What does Sb mean on my LG refrigerator?
Sb stands for Sabbath mode, a feature that disables lights, sounds, and automatic functions to comply with religious observances. It's not an error but a special operating mode.
How did my LG refrigerator get into Sabbath mode?
Sabbath mode is usually activated accidentally by pressing the wrong button combination, or intentionally for religious observances. It can also be triggered if buttons are pressed while cleaning the control panel.
Will my food spoil if Sabbath mode is on?
No, your food will not spoil. Sabbath mode only disables lights, sounds, and dispensers - the cooling system continues to operate normally to maintain proper temperatures.
Why won't my LG refrigerator lights turn on?
If your refrigerator displays Sb and the lights won't turn on, this is normal Sabbath mode behavior. The lights are intentionally disabled and will return once you deactivate the mode.
Can I use the ice and water dispenser in Sabbath mode?
No, the ice and water dispensers are typically disabled in Sabbath mode. You'll need to deactivate the mode to restore normal dispenser operation.
