The evaporator fan has failed
That is what SY EF, or SY-EF, tells you. The code appears in Frigidaire service data sheet 242321500 for the FFHN2740PS/PE and sheet A01544701 for the FGHG2366PF, both bottom-freezer ice and water refrigerators.
Fan test in System Diagnostic Mode
No steps for the owner are given.
A technician runs the evaporator fan test, where the fan should run when the setting reads LO or HI and stop when it reads off.
Listening for a change in speed between LO and HI is part of the check.

Model compatibility: Frigidaire 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.

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.
