Frigidaire Refrigerator Error Code Sb

The 'Sb' display on a Frigidaire refrigerator indicates that Sabbath Mode is active. This is not a fault condition or error in the traditional sense. It is an intentional operating mode designed to comply with Jewish Sabbath and holiday observances, during which the use of electricity in certain ways is restricted. When Sabbath Mode is engaged, the refrigerator continues to cool and operate normally, but most user-facing features are suppressed to prevent unintentional activation of electrical functions.

In Sabbath Mode, the control board disables or suppresses several standard functions including interior lighting, audible alarms, dispenser operation, and most display indicators. The refrigerator and freezer compartments maintain their set temperatures automatically, but the user cannot interact with the display or trigger lighting events by opening doors. The control system essentially enters a restricted interface state while the core refrigeration cycle continues uninterrupted.

Sabbath Mode is activated and deactivated through a specific button combination on the control panel. On Frigidaire models, this is done by simultaneously pressing and holding the freezer side '-' button and the refrigerator side '+' button for five seconds. The mode persists through normal use and will not cancel on its own, so if the display shows 'Sb' unexpectedly, the mode was likely activated accidentally through an unintentional button combination.
