LG Refrigerator Sb — Sabbath Mode active (not a fault)

LG Refrigerator · Error code Sb

What Sb Means

Sb is not an error — it indicates Sabbath Mode is enabled. In Sabbath Mode the dispenser, lights, alarms, fans and display behaviors are altered to comply with religious observance.

Symptoms

  • Sb shown on display
  • Dispenser doesn't respond
  • Door alarms silenced
  • Interior light may not come on
  • Display dimmed or blank

Common Causes

1
Sabbath Mode was activated

Intentional setting or accidental key combo.

2
Power restored while in Sabbath Mode

Mode survives a power blip.

How to Fix It

  1. Press and hold Freezer + WiFi (or Refrigerator + Ice Plus, varies by model) together for 3–5 seconds.
  2. Sb will disappear from the display when mode is exited.
  3. If unsure of the key combo, consult the model's owner manual.
  4. No repair is needed — this is a user-selectable mode.
