I have a LG refrigerator that the black coating is coming off the doors again. They were replaced once and a year later the coating again is starting to peel off in the same place. the warranty is up obviously and im going to be selling my house soon and thie refrigerator will look bad. when the doors were replaced last time the guy told me LG fixed the problem and it wont happen again. anybody have any idead on what I should do?
