I'm the not-so-proud owner of the LG refrigerator LMXS30776S/03. Does anyone have any test procedures for the evaporator fan or a schematic of the motherboard? ice maker and water don't work and the manual defrost procedures didn't work either. I'm thinking of the evaporator fan but am unsure. The frig and the freezer seem to be working fine. I manually defrosted the freezer only and the error went away for a while. I unplugged the unit which did a reset and the error went away for a while. Any and all help appreciated.
