Frigidaire Refrigerator SB / Sb Error Code

Frigidaire says SB or Sb means Sabbath Mode is enabled, which can disable portions of the controls or display depending on the model.

Applies to Frigidaire refrigerators with Sabbath Mode

What the appliance detected

Detected condition

Sabbath Mode is active on the refrigerator.

What may contribute

Possible causes

  • Sabbath Mode may have been turned on intentionally or accidentally.
  • Model-specific controls determine how the mode is turned off.
  • Some alarms may still operate for health or safety reasons.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the display and model

    • Photograph or write down the exact alert, word, or code before clearing it.
    • Confirm the full model number and Frigidaire owner manual because displays and controls vary by refrigerator family.

  2. Use only documented external checks

    • Confirm the display shows SB or Sb rather than another code.
    • Use the exact owner manual to exit Sabbath Mode; do not guess button combinations.
    • After the mode is off, confirm cooling and temperature displays behave normally.

  3. Stop before internal work

    • If the alert remains after documented checks, request service.
    • Do not open sealed-system, compressor, fan, sensor, wiring, dispenser-motor, or control areas.

Actions not recommended

  • Do not perform refrigerant, compressor, or sealed-system work.
  • Do not test live voltage or open internal electrical areas.
  • Do not replace sensors, boards, fans, valves, or dispenser parts based only on the display.

When to stop and request service

  • Sabbath Mode cannot be turned off using the documented controls.
  • Cooling or temperature behavior is abnormal after exiting the mode.
  • The display shows a different alert after Sabbath Mode is cleared.
