Quick Q&A

Quick answer: LG refrigerator SB usually means Sabbath Mode is turned on. It is not a repair code. To turn it off, LG says to press and hold the Freezer and Wi-Fi buttons for 3 seconds. :contentReference[oaicite:4]{index=4}

What This Display Usually Means

Sabbath Mode is a settings mode, not a hardware failure. LG’s support page says SB indicates Sabbath Mode used for the Jewish Sabbath and holidays. While active, the refrigerator changes how some convenience functions behave. :contentReference[oaicite:5]{index=5}

LG specifically says selecting Sabbath Mode automatically turns off the alarm functions and disables the dispenser. That is why SB can be confusing: homeowners may think the refrigerator has a problem, when it may simply be in a special operating mode. :contentReference[oaicite:6]{index=6}

This also makes SB different from LG refrigerator fault codes like FF, RF, EID, or FS, which point to actual fan, sensor, or ice maker issues. :contentReference[oaicite:7]{index=7}

What You May Notice

• SB appears on the display
• The display may also look like S6, 5b, or 56
• The dispenser does not work
• Alarm functions are disabled
• The refrigerator may otherwise still cool normally

That symptom pattern fits a mode setting much more than a cooling-system failure. LG’s own page treats SB as Sabbath Mode rather than as a repair code. :contentReference[oaicite:8]{index=8}

How To Turn It Off

1. Wake the display if needed

LG says to touch the display to activate it before turning Sabbath Mode on. In practice, if your panel is dim or sleeping, waking the display first can help before trying to turn the mode off as well. This is an inference from LG’s published turn-on steps. :contentReference[oaicite:9]{index=9}

2. Press and hold Freezer and Wi-Fi for 3 seconds

LG says to turn Sabbath Mode off manually, press and hold the Freezer and Wi-Fi buttons for 3 seconds. :contentReference[oaicite:10]{index=10}

3. Check whether SB disappears

If the setting changes successfully, the SB display should clear and normal panel behavior should return. LG’s page frames this as a mode setting, so the display should stop showing SB once the mode is turned off. :contentReference[oaicite:11]{index=11}

4. Wait it out if needed

LG says Sabbath Mode automatically turns off after 96 hours. So even if someone enabled it by mistake, it is not permanent. :contentReference[oaicite:12]{index=12}

5. Do not treat SB like a failed-part code

SB is not the same type of issue as an FF fan error, EID ice maker sensor failure, or Demo Mode. LG separately lists those conditions with different meanings and next steps. :contentReference[oaicite:13]{index=13}

What SB Usually Does Not Mean

• It does not usually mean the refrigerator is broken
• It is not the same as Demo Mode or Display Mode
• It is not the same as an ice maker, fan, or sensor error

LG’s error-code page separately identifies OF F as Demo Mode or Display Mode, which disables cooling, while SB is Sabbath Mode. Those are different settings with different button actions. :contentReference[oaicite:14]{index=14}

What Beacon Usually Checks

When our friendly technicians in yellow help with an LG refrigerator showing SB, we usually start by making sure it is really a settings issue and not a different code being misread:

• Whether the display is actually showing SB, S6, 5b, or 56
• Whether the refrigerator is still cooling normally
• Whether the dispenser is disabled because Sabbath Mode is active
• Whether the mode can be turned off with the published button sequence
• Whether a different display mode or true fault code is being confused with SB

That helps separate a simple settings issue from a real repair problem. LG’s official guidance strongly supports treating SB as a mode setting first. :contentReference[oaicite:15]{index=15}

When To Call Beacon

Call Beacon if the refrigerator is not cooling normally, if the display will not exit SB after using LG’s button steps, or if you are not sure whether the display is actually showing Sabbath Mode or a different code. If it turns out to be a different LG code, the fix path can be very different. :contentReference[oaicite:16]{index=16}
