Are you sure it was the plug? How could there be lights? The reason I mention it is I had a month old new GE Profile refrigerator and it did the same thing. They "rebooted" it by tripping the main electrical switch (easier than pulling it out and unplugging it. It reset the onboard computer but a few days later went out again. They replaced the board and again it was running but a few days later the refrigerator stopped cooling but I still had lights. I ended up having the store replace it. Interesting you have the same problem with a GE but another model.
