Product review (5 stars): by LG refrigerator failed to cool. After installing this new board
This replacement board worked exactly as intended, and fixed my "ER FF" Issue. After plugging my fridge in after being dormant for several months, by LG refrigerator failed to cool. After installing this new board, I put into TEST mode 3 to fully defrost the evaporator until it was completely clear. Fridge then regained full functionality and began cooling again!
