Error codeSY EF
ApplianceRefrigerator
An evaporator fan failure is what SY EF stands for on an Electrolux refrigerator. Service data sheet 242173200 phrases it slightly differently, as the evaporator fan circuit.
Where it applies
Bottom-freezer and ice-and-water refrigerators with a UI board. Models named in the Electrolux sheets, in a different order: EW26SS85KS, EW23CS85KS, EI23CS65KS, EI23CS35KB, EI23CS35KS, EW23BC85KS, EI23BC65KS, EW28BS85KS, plus the EI23BC30 series in KS, KB and KW finishes.
First look by a technician
Pins that have backed out of their connectors.
Wires that are pinched or damaged.
A decision on whether the component, the main control board or the wiring is at fault, made before any part is swapped.
If you see a different SY code
SY CF means the UI and the main control board could not communicate at start up.
SY CE is a UI and board communication error that appears after the refrigerator has been in operation.
Refrigerator repair for San Francisco homes
Should SY EF remain, Electrolux refrigerator repair is available to San Francisco and Bay Area households on (415) 449-0036. Have the model number to hand, and mention the code exactly as it reads on the display.
Model compatibility: Electrolux reuses codes across series and model years, so SY EF may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
