Error codeSB
ApplianceRefrigerator
Quick answer
SB on a Frigidaire refrigerator means Sabbath Mode is on. It is not a fault, and the display shows Sb.
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
Sabbath Mode is active (not a fault); the display shows Sb.
When a Frigidaire refrigerator shows Sb, Sabbath Mode is on. It is a setting, not a fault. The mode is designed to let the appliance function with minimum power to conform with religious guidelines.
Turning it on or off
Press and hold the “-” key and the “Temp F-C” key together for five seconds. The same press switches Sabbath Mode on and off, and the display shows Sb while the mode is active.
If the display behaves oddly after Sabbath Mode is switched off, call (310) 861-3938 about Frigidaire refrigerator repair in Los Angeles, and say what the display shows and which keys you pressed.
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.
