The SY EF code means your evaporator fan is jammed or faulty. I usually find that ice buildup is blocking the blades or the motor itself has failed electronically. You should check for frost in the freezer and verify the fan can spin freely before replacing any parts.
SY EF is one of the most common calls I get on Frigidaire fridges. The evaporator fan in your freezer stopped spinning, so cold air isn't moving into the fridge section anymore. Nine times out of ten it's ice blocking the blades or a dead motor. Ignore it and your fresh food section warms up completely while the freezer stays cold, so don't sit on this one.
OK so here's what's happening. Your Frigidaire's control board is watching the evaporator fan with a tachometer signal, and when it stops getting that feedback, it throws SY EF. I see this constantly, usually after a door gets left open overnight and ice jams up the blades. The fix is usually $60-$100 in parts if you do it yourself, and most people can handle it in under an hour.

Symptoms You May Notice
Your fridge section is room temperature or warmer, but open the freezer and it's still cold, maybe even colder than usual because the compressor is running overtime.
Complete silence from the freezer. No fan noise at all, which is definitely not normal for a running fridge.
A solid sheet of ice covering the entire back wall of the freezer behind the panel.
Clicking or chirping sound from the freezer, like something's trying to spin but keeps catching on ice.
SY EF flashing on the display, sometimes cycling with the temperature readout.
Can you reset a Frigidaire refrigerator to clear the SY EF code?
After the repair, unplug the fridge for five to ten minutes. Plug it back in and the board runs through its startup sequence automatically. If the fan spins up properly, the code should clear on its own within a few minutes. Don't panic if SY EF flashes briefly at startup, give it five minutes. Still there after ten minutes of normal running? Check that your fan connector is fully and firmly seated.

Frequently Asked Questions
Can I still use my refrigerator with the SY EF code?
Honestly, not for long. The freezer might hold temp for a while since the compressor is still running, but your fridge section is going to warm up fast because there's no cold air circulating into it. We're talking a few hours before your milk is in the danger zone. Pull anything perishable out and get it into a cooler while you work the fix. Don't sit on this one overnight thinking it'll sort itself out.
Why did my Frigidaire start showing SY EF after a power outage?
Two things can happen in a power outage. The surge when power comes back can fry the small tachometer circuit inside the fan motor, and second, if the outage was long enough that your freezer partially thawed and refroze, that meltwater can lock the blades solid. I see both pretty regularly after big storms. Try the hard reset first. Then check for ice. If the motor took a surge hit, you'll need a new one, no getting around it.
Is the SY EF error the same as the SY CF error?
Nope, totally different problem. SY EF is your evaporator fan in the freezer. SY CF is a communication failure between the main control board and the display board on the door. They just happen to have similar-looking names. SY CF usually means the ribbon cable or the display board itself is bad. Don't go pulling your freezer panel apart for an SY CF code, you'd be fixing completely the wrong thing.
How much does it cost to fix an SY EF error?
If you're doing it yourself, a replacement evaporator fan motor runs $60-$100 depending on the model. Part number 5304518867 fits a lot of the common Frigidaire Gallery series. If you call a tech, figure $200-$300 all in with the service call and labor. Labor on this is usually about an hour of actual work, maybe a little more if there's a heavy ice situation. It's a pretty DIY-friendly repair if you're comfortable with a screwdriver and a multimeter.
How do I know if it's the fan motor or the control board causing SY EF?
This is the key question, and the voltage test in step 5 answers it clearly. If you've got 12V at the fan connector but the fan won't spin, it's the motor. Period. If you've got no voltage at the connector even though the board should be running the fan, it's probably the board. Control boards run $150-$300, so don't replace it until you've actually tested voltage. I've seen people swap boards when a $70 fan motor was the actual problem. Test first, spend money second.
