Freezer Fan Assembly ADP73694301

Hello Carol, thank you for your question! If your LG refrigerator is displaying a 1F or IF error code, it means the control board is detecting an issue with the ice maker, which is most likely caused by frost buildup around the ice maker fan. If you see no frost around the ice maker fan, then the fan motor, part number PS3523330, may need to be replaced or reset to fix the issue. We hope this solves your problem!

Hi Anna, thank you for asking. We have found that the E FF error code on an LG refrigerator means there is a freezer fan problem. The part number you mentioned is just the blade. We would recommend checking the evaporator fan motor, part number PS11761149, to fix the issue. We hope this helps, good luck with this repair!

Hello Charlotte, thank you for reaching out to us. Based on your description that the noise stops immediately when you open the door, it is highly likely that the evaporator fan motor in the freezer compartment is failing or is obstructed by ice buildup. Manually defrost the refrigerator. Unplug the unit, remove all food, and leave the freezer door open for 8–12 hours (or use a hair dryer carefully) to melt the ice behind the back panel. If this does not help, you will need to replace the evaporator fan motor, part number PS3523326, to fix the issue. We hope this information helps!
