This refrigerator has had problems with the evaporator fan freezing for several years. We get the error code ER IF. Usually a blow dryer can solve the problem. However, recently it did not and my husband took the back off the freezer, completely defrosted and removed the ice. The error code went away and water now dispenses and also runs into the ice maker. But the ice maker is not freezing. There is not an error message. The cold air from the freezer does not seem to be blowing through the vents to the ice maker. Do you know what the problem could be and how to fix it?

I just wanted to make a correction to the error code we have been having issues with. I couldn't figure out how to edit my post. The error code is ER FF.

Hi,

Ok, Error Code ER FF is the freezer fan.

Take a voltage reading on Con 7 on your main control board, which is located in the back of the refrigerator. The voltages are DC not AC.

Here's the control board for your model:

Here's the freezer fan motor for your model:

Let us know what you find.
