What SB / Sb Means
SB or Sb in both windows means Sabbath mode is on: the refrigerator runs with minimum power and features to conform with religious guidelines, in Electrolux’s words. The owner guide toggles it by holding minus and Temp F-C together for five seconds; the service data sheet for EI23BC models lists FZ DOWN plus FF UP.
Common Causes of SB / Sb
- Sabbath mode switched on, sometimes by accident when adjusting temperatures
🔧 One Safe Check You Can Try
Use the combination in your use and care guide to turn Sabbath mode off. Lights, the dispenser and alarms behave differently while it is on, which is expected.
⚠ Why You Shouldn't Go Further Than That
- No repair is needed.
- If Sb cannot be turned off, a stuck key may be involved.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
