Electrolux Refrigerator Error Code SY EF — Evaporator Fan Circuit Failure
What this means
The SY EF error code on Electrolux refrigerators indicates the main control board has detected a problem with the evaporator fan motor circuit. The evaporator fan circulates cold air from the evaporator coils throughout the refrigerator and freezer compartments. Without it, the fridge will not cool properly even though the compressor may be running. Causes include a failed fan motor, a frozen fan blade, damaged wiring, or a control board output failure.
Alternate codes: SYEF, SY-EF, 5Y EF
Step-by-step fix
4 stepsListen for the fan
Open the freezer door and listen for the evaporator fan. It should be running when the compressor is on (you may need to hold the door switch in). If you hear nothing or a buzzing/grinding noise, the fan has a problem.
The evaporator fan is located behind the back panel inside the freezer compartment.
Check for ice buildup
Remove the freezer's rear interior panel to expose the evaporator coils and fan. If the fan blades are encased in ice, the fan cannot spin. Use a hair dryer on low heat to carefully thaw the ice. Determine why ice built up (bad defrost system).
Excessive frost around the fan often points to a failed defrost heater, defrost timer, or defrost thermostat.
Test the fan motor
Disconnect the fan motor wiring and test for continuity with a multimeter. Also try spinning the fan blade by hand — it should turn freely. If the motor has no continuity or the shaft is seized, replace the motor.
The fan motor should read between 200–800 ohms depending on the model.
Check the wiring to the control board
If the fan motor is good, inspect the wiring from the fan to the main control board for breaks or damage. Test continuity through each wire. A broken wire prevents the board from powering the fan.
Wiring through the hinge area on French door models is particularly prone to wear.
When to call a professional
If the fan, wiring, and motor are all fine, the main control board's fan output circuit may be faulty. A technician can test the board output.
