We don't know why, but the refrigerator freezer and icemaker began working last night after we threw out all the defrosted food. Repair people didn't give us the courtesy of a call today even though they said they would. Don't yet know what to think about this Samsung refrigerator. Will it quit again? Why did it conk out in the first place? JUST WHAT IS GOING ON?? Are we in the Twilight Zone?
