What does "Sy EF" mean on dispenser led?

Unfortunately, the SY EF error can mean a problem with the electronic control board or the fan. Check your wiring. It's possible that the wiring harness isn't fully seated (at the fan in the freezer or the electronic control board) or one of the wires in the harness is broken. If those are okay and the problem persists, then a new control board is needed.

I wish that I had better news for you.

Hello Suzanne, thank you for your post!

I understand that your Electrolux refrigerator is displaying an error code of "SY EF". An "SY EF" code stands for an evaporator fan circuit failure. This could also be a miscommunication with your refrigerator and I would advise performing a reset on your refrigerator. You can reset it by disconnecting the power plug from the outlet for roughly ten minutes. If that does not help correct your issue you may need to replace your main control board or a wiring harness. For proper disassembly and repair of your refrigerator I would recommend having a professional technician for proper diagnosis and repair. I hope this information is helpful. -Matt

Are all of the lights flashing or is it flashing a code like Sy EF or Sy CE? If so the ef would indicate the evaporator fan circuit has a problem, and if it is SY CE it would indicate a communication error.

For instructions on getting a new solenoid valve as well as various other parts, check the parts manual for the refrigerator:

Good Morning Friend,

I understand you are receiving an "SY EF" code on your Frigidaire refrigerator, model# FRS3R5EMB. The "SY EF" code stands for system error with the evaporator fan. This possibly means that there is something going on with your evaporator fan or it could possibly be a false error code. . I suggest resetting your appliance, by either unplugging it or shutting the power off at your home's circuit breaker, for 3-5 minutes. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully.

Good Afternoon Friend,

I understand you are receiving an SY EF code on your Frigidaire refrigerator, model# FGUN2642LF. This code states there is a system error code that deals with the evaporator fan. This could also be a possible false error code. I suggest you reset your appliance, by either unplugging it or shutting the power off at your home's circuit breaker, for 3-5 minutes. Once power is restored, you will need to press the "Mute Sounds" button to stop the power failure alert. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your refrigerator status has changed successfully.

Hi M - I am happy to assist you! Error codes SY/EF is commonly refer to a failure with the evaporator fan circuit. Let's try resetting the refrigerator by either unplugging it or flipping the household circuit breaker to the off position. It is important to wait roughly ten minutes and then turn the unit back on. If resetting the power does not correct the issue, then more than likely there is a potential wiring failure between the main control board and evaporator fan. In this regard, I would personally suggest to reaching out to a repair tech to further evaluate and repair you appliance. If you have further questions, please do not hesitate to reconnect.

I just got the same note on mmt refrig. Do u know the answer?
