Hi, My 4 year old Lg fridge started to not cool well and freezing the lower items and giving me the Er rF error code. I ordered a new control board part# EBR73093617 last week. Well that did not fix the problem. When put on Test Mode 1 everything works and you can feel air from the side ice vents and in the freezer part. Is there anyone with any troubleshooting tips?

Hi Nicolas,

Yes, its likely going to be the refrigerator fan motor you will need to replace, Er rF=Refrigerator Fan

Rick helped another member with this same error code as yours, start reading at post #14 here: Recurring Error code Er rF - Page 2 He tells you how to test the voltage to it.

Here's that refrigerator fan motor for your model you can order:

Thank you for that information. Do I test the voltage while it's in the Test Mode #1? Or while it give the Er rF code?

Either one, it does not matter.
