Error codeSB

Sb is a setting
When the display reads Sb, the refrigerator is in Sabbath Mode. Nothing is broken. The mode lets the appliance run on minimum power so that it follows religious guidelines, and Frigidaire provides it on its refrigerators.
How to toggle it
Locate the “-” key and the “Temp F-C” key.
Press and hold both together for five seconds.
Do the same press again to reverse it: the mode turns on or off each time, and Sb stays on the display while it is active.
Once Sabbath Mode is off and the display still acts up, our Frigidaire refrigerator repair line serves San Francisco and the Bay Area at (415) 319-6371. Report what the display shows and which keys you pressed.
Model compatibility: Frigidaire reuses codes across series and model years, so SB may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
SB (shown as Sb) means Sabbath Mode is active, a setting rather than a fault.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
