What Sb
actually means.
Sb means Sabbath mode is on. LG says it is not an error code: the temperature cannot be changed, and the timer, light and alarm functions are disabled until the mode is turned off.

What to do when Sb shows on the stoveKind of codeMode, not a failure
Something the stove was switched into, often by accident, rather than something that broke: a control lock pressed while wiping the panel, a Sabbath setting, a showroom demo mode that lights the display and heats nothing, a reminder that a spot on the stovetop is still hot. No part is worn out, and the stove's own keys put it right.
Usually leads toNo repair
Check the display for Sb, which LG's list also shows as 5b.
Shows up asStove Display Blank or Flashing
The clock and display on the stove have gone dark, or they flash the time, a word or a string of characters and ignore the keys you press.

Sb is listed here: LG's Help Library code list (Wayback copy of 23 June 2025); the list names no models, so the rating label decides whether your stove can show it.
Before you book,
in this order.
Each step comes from LG's own guidance for Sb on its stoves. Follow it to the end: the last card says whether this is a visit.
Check the display for Sb, which LG's list also shows as 5b.
To leave Sabbath mode, press Bake, set a temperature with the plus and minus keys, press Start, then press and hold Clock for 3 seconds.
If Sb returns on its own, book a visit.
Cleared?
The stove is working again and no part was needed. If the same letters come back while a burner or the oven is on, or the stove switches itself off again in the middle of dinner, book it as a new problem.
What not to do
Sb is not a frozen or broken control. The keys are ignored on purpose while Sabbath mode is on.

In LG's own words
This is not an error code.
Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. Sb is listed here: LG's Help Library code list (Wayback copy of 23 June 2025); the list names no models, so the rating label decides whether your stove can show it.
