Our LG stainless side by side refrigerator freezer broke on Friday. It is only 18 months old. It has an ice / water dispenser on the freezer door.
We called a number of repair shops, and, to make a long story short, we were getting the bad news that the repair would require us to buy a four hundred dollar circuit board, plus labor, plus we would have to wait for two weeks for the part.
Fortunately, the repair man and I got to talking about the fact that we both have five year old girls, how hard it is to absorb something like this just three weeks out from Christmas, and he offered: "you could just unplug it for an hour and then plug it back in." I had the impression that he was not supposed to tell me that.
Well, sure enough, we unplugged for an hour, plugged it back in, and now, here it is Monday, and the refrigerator is working fine. It seems like rebooting a computer.
So -- if this ever happens to you -- try unplugging the refrigerator, waiting an hour, and then plugging it back in.
