Frigidaire Refrigerator SY EF Error Code (5Y EF): Evaporator Fan Failure (Meaning, Causes, Fixes)

Reviewed 2026-10-22 · Based on 6 manufacturer & service sources

What the code means

Frigidaire's service data sheets for Ice & Water bottom-freezer refrigerators (for example sheets 242292100 and A01544601, used on models like the FGHB2866) list SY EF in the error-code table as Evaporator Fan Failure. The display may look like 5Y EF because an S and a 5 look the same on a seven-segment display. The evaporator fan sits behind the freezer's back panel and pushes air over the cold evaporator coil into the freezer and fresh food sections, so when it stops the fridge warms up even though the compressor may still be running. Frigidaire's owner support page for French-door alarms puts SY EF on its short list of codes that could indicate authorized service is required, alongside SY CF, SY CE, OP and SH. Sears PartsDirect describes the code as an evaporator fan circuit failure and gives a check order: the fan's harness connection in the freezer, then the fan wires at the control board, then the fan, then the board.

Likely causes

Safe DIY checks

⚠ Before you start

Unplug the appliance (or switch off its breaker) and shut off the water supply valves before removing panels or disconnecting hoses. Keep towels handy for residual water.

  1. Check the temperatures first. Put a fridge thermometer in each section; if food is warming, move the most perishable items to a cooler while you troubleshoot.
  2. Reset the refrigerator: unplug it, wait 2 to 3 minutes (Frigidaire's hard-reset guidance) and plug it back in. If the code was a one-off glitch it won't come back.
  3. Listen inside the freezer with the door closed and the door switch pressed. A working fan makes a steady whir; silence or a ticking or scraping sound points to a frozen or blocked blade.
  4. If you see heavy frost on the freezer's back panel or the fan is iced in, unplug the refrigerator, move the food, and let it thaw completely with the doors open (put towels down for the meltwater). Then plug it in and see whether the code returns. Repair guides note that if the frost comes back over the next days or weeks, the defrost system needs repair and the fan was only the symptom.
  5. If you're comfortable removing the freezer's rear panel with the fridge unplugged, check that the fan blade spins freely by hand and that its wire connector is pushed fully together. Sears PartsDirect says to reconnect the harness plug if it's loose.
  6. If SY EF comes back after a reset and a full thaw, stop here and book service. Frigidaire lists it as a code that may need authorized service.

🛠 When to call a pro

  • SY EF returns after a reset and a complete defrost.
  • The freezer keeps frosting over, which points to a defrost heater, thermostat or control fault. The service data sheet lists the defrost specs (a 500-watt, 26.5-ohm heater on the covered models, running about 24 minutes every 6 to 96 hours of compressor run time) for the technician.
  • Electrical testing: the service data sheet's System Diagnostic Mode (test 15, Evaporator Fan) lets a technician switch the fan on and listen for the speed change from LO to HI, and AppliancePartsPros describes checking for about 12 volts DC at the fan during that test. Power present with no fan means the fan motor; no power with good wiring means the control board.
  • Wiring: Frigidaire's sheet tells technicians to check for pin back-outs and pinched or damaged wires before replacing parts, and to contact Frigidaire's technical support before replacing the main control board.
  • The refrigerator is under warranty. Use the contact options on Frigidaire's owner support site to schedule service.
