Update to my issue. Yesterday morning I saw for the first time a panel display that reads SY EF which I believe refers to a problem with the evaporator fan located on the back panel of the freezer. As I stated in my original post,with crossed fingers and knocking on wood,the freezer is still working as should and producing ice albeit at what seems to be a slower rate than before this issue started.
I can unplug the refrigerator for 10 minutes,plug it back in and the SY EF prompt is cleared for at least 1.25 hours as I have done so again this morning and have been timing it as best as possible.
As for fans behind the back access cover,I can visibly see one which I assume cools the compressor.When I checked on Monday it was operating.
My question regarding the evaporator fan in the freezer: is the fan motor itself bad or is there an issue with the control board that is throwing the SY EF code when the control board attempts to turn it on?
