Error codeSb / SB
ApplianceRefrigerator
Sb is a setting
On screen: Sb (spelled SB in the guide’s text)
Meaning: Sabbath mode is active
Purpose: low-power running that follows religious observance rules
Not a fault
Switching it on or off
Find the “−” and “Temp F-C” keys on the control panel.
Keep both pressed for a count of five.
That one gesture works in both directions, and Sb remains on the display only while the mode is on.
Further instructions live in the use and care guide, which the owner guide names.
If the refrigerator seems off afterwards
Once the mode is off, a refrigerator that still misbehaves has two reset routes in the guide: half a minute without power from the plug, or a trip of the breaker. Within 30 days of installation the installer is your contact; beyond that, schedule Electrolux service.
Other display messages
See PF for the power failure light and H or HI for the high temperature alarm.
Model compatibility: Electrolux reuses codes across series and model years, so Sb / 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
Sb, written SB in the guide, means Sabbath mode is active, a minimum-power setting and not a fault.
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.
