Frigidaire Refrigerator Error Code SB — Sabbath Mode Active
What this means
Error code SB (or Sb) indicates the refrigerator has been placed in Sabbath mode. This is not a malfunction — it is a feature designed for religious observance that disables the interior lights, alarms, and display changes while maintaining cooling. The display will show SB until the mode is deactivated.
Alternate codes: Sb
Step-by-step fix
3 stepsIdentify Sabbath mode
Confirm that SB or Sb is displayed on the temperature panel. The refrigerator will still cool normally but lights and alarms will be disabled.
If you didn't intentionally activate this mode, it was likely triggered by an accidental button combination.
Deactivate Sabbath mode
Press and hold the UP and DOWN temperature arrows simultaneously for 5 seconds (on most models). The display should return to normal temperature readings.
The exact deactivation method varies by model — check your owner's manual if the standard method doesn't work.
Verify normal operation
After deactivating, check that the interior light turns on when the door is opened and the display shows temperature readings.
If the display still shows SB after following the deactivation steps, try unplugging for 5 minutes.
