The control has detected a problem with the fan that circulates cold air from the freezer's cooling coil. If the fan stops, cold air doesn't reach the compartments and they warm up even though the compressor runs. Common causes are a loose fan connection, ice blocking the fan, or a failed fan motor.

Listed by Frigidaire as a service code on French-door models.

Safety first: unplug the refrigerator (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Frigidaire SY EF

  1. Reset the refrigerator

    Unplug it for 30 seconds and plug it back in, or flip the breaker. See whether the code returns.

  2. Listen for the fan

    After the doors have been shut for a few minutes, open the freezer and listen right away at the rear vents for air movement, since on many models the fan pauses once a door opens. A scraping or ticking sound can mean ice is touching the blade.

  3. Defrost safely if ice is present

    If the freezer back wall is heavily frosted, unplug the refrigerator, move food to coolers, and let the ice melt naturally with the doors open and towels down. Never use a heat gun, hair dryer, or sharp tool.

When to call a technician

If SY EF returns, a technician should check the fan wiring, then the fan motor and the control board.
