GRILLE ASSEMBLY,FAN AEB74004901

Hi Josh, Thank you for your question. The E FF error code indicates that the evaporator fan motor in the freezer section, part number PS3523323, is not operating normally. Inspect the motor to see if there is a build up of ice around it preventing the fan blade from turning. If there is, you will need to defrost the refrigerator. If there is no ice obstructing the fan blade, try unplugging the refrigerator for 5 minutes and plug it back in. If the error code returns, you will need to replace the evaporator fan motor. We hope this helps!
