What Does Error Code Sb Mean on a LG Oven?

Sabbath Mode active — controls intentionally disabled (not a fault).

Sb is a status indicator, not a fault. When Sabbath Mode is activated, the control board deliberately suppresses the display, audible tones, and most touch controls so the oven can hold a set bake temperature without prohibited interaction during religious observance. Because it is user-enabled, no diagnostics run and no error is logged. Unlike PF, which flags a past power interruption, Sb reflects an intentional operating state; after a power failure the display may return showing Sb with the oven off.

Models affected: LG electric and gas ranges/ovens with a digital control panel offering a Sabbath Mode feature, including models such as LREL6325F and LRGL5825F
What owners report: Owners commonly report seeing Sb unexpectedly after accidentally holding the Sabbath or Clock button, or after a power outage restores the panel in this mode. The usual quick win is a roughly three-second hold of the Sabbath/Clock control per the manual to clear it and restore normal operation.

Frequently Asked Questions

Can I keep using my LG Oven when error Sb appears? +
Usually yes — Sb is a low-severity normal notice that rarely stops the oven from working, but clearing the underlying cause prevents it from escalating.
What most commonly causes Sb on a LG Oven? +
Across reported LG oven repairs, the most frequent is sabbath Mode enabled (100% of cases). Check them in that order before replacing any parts.
Sb keeps coming back after a reset — what should I check next? +
A reset only clears the stored Sb fault; if it returns, the normal problem is still present. Move on to the physical checks — exit Sabbath Mode — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.

A DIY repair typically runs $0–$0 in parts, versus $0–$0 for a professional service call. Expect the work to take about 10–20 minutes.
Which LG Oven models show error Sb? +
Sb is documented on LG electric and gas ranges/ovens with a digital control panel offering a Sabbath Mode feature, including models such as LREL6325F and LRGL5825F. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
