Refrigerator Doors Whistling

On new refrigerators, it is not unusual for the door to whistle or squeak. This occurs because the gasket (rubber material around inner perimeter of the door) is sealing very tightly. If the noise becomes bothersome, try rubbing paraffin wax or petroleum jelly on the gasket.This noise will stop in a few days once the gasket becomes more pliable.  This is a normal occurrence and does not indicate a problem with your refrigerator or freezer.
