What to do when Sb shows on the applianceKind of codeSetup modes, not failures
Nothing is wrong with the new appliance; it has come out of the carton in a state the store or the factory left it in. A showroom or demo mode lights the display and the fans while the unit never cools or heats, a Sabbath setting holds the oven light and hides the controls, a control or shipping lock refuses every key, and some laundry and dish care machines ask for a first calibration cycle before normal use. The manual gives the key sequence that turns each one off; once it is off, the appliance runs as it should.

Confirm whether the household intends this mode to be active before assuming the panel is unresponsive.
Shows up asAppliance Installation Code on a New Unit: Setup Modes and Hookup Messages
An appliance installation code is a message a new unit shows because of how it was set up: a demo mode, a water or drain alert, a vent warning or a power check.

LG installs span refrigerators with water lines, stacked or side-by-side laundry, dishwashers and ranges, often with a Wi-Fi setup at first power-on.

LG documents Sb on its range and wall oven control platform; the exact exit sequence can vary by model.
Before you book,
in this order.
Each step comes from LG's own guidance for Sb on its appliances. Follow it to the end: the last card says whether this is a visit.
Confirm whether the household intends this mode to be active before assuming the panel is unresponsive.
Use the documented sequence for the model — commonly pressing Bake, setting a temperature, pressing Start, then holding Clock — to exit the mode.
Confirm the timer, light and alarm functions return once the mode is cleared.
If Sb will not clear with the documented sequence, book a visit rather than repeatedly cycling the breaker.
Cleared?
The message has gone from the display, the setting or connection behind it has been corrected, and the new appliance finishes a full first cycle without raising it again. A setup code that comes straight back after the hookup has been checked points to something the install missed, such as a kinked hose or a harness left unplugged, so note it when you book.
What not to do
Sb does not indicate the keypad or the electronic control has failed. LG's own wording says directly that this is not an error code, and the unit behaves exactly as documented while it is active.

A booking moves faster with three things: the message exactly as the display shows it, the model number from the carton or the rating plate, and the moment it first appeared. With those, the office can tell whether it is a setup step or a connection to put right, and send the part that fixes it.
