Refrigerator
SY CF is what an Electrolux refrigerator shows when its user interface (UI) cannot talk to the main control board during start up.
Facts about the code
- Shown as the letters SY followed by CF.
- Reported for the bottom-freezer and ice-and-water designs that carry a UI board.
- Listed in three Electrolux service data sheets for these models: EI23BC30KS, EI23BC30KB, EI23BC30KW, EW28BS85KS, EI23BC65KS, EW23BC85KS, EI23CS35KS, EI23CS35KB, EI23CS65KS, EW23CS85KS, EW26SS85KS.
Technician-side diagnosis
- Inspect the connectors for pins that have backed out, and the harness for wires that are pinched or damaged.
- Work out whether a component, the main control board or the wiring is responsible.
- Only then replace anything.
None of this is an owner task; the sheets describe it as service work.
Codes with a similar look
- SY CE is the same kind of UI and board communication fault, but it turns up once the refrigerator has already been running.
- SY EF also begins with SY, though it concerns the evaporator fan.

Bay Area owners whose display stays on SY CF can look at Electrolux refrigerator repair and phone (415) 449-0036. Before calling, write down the model number and note what the refrigerator did when it was powered up.
Model compatibility: Electrolux reuses codes across series and model years, so SY CF may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
