Appliance: Frigidaire 3.1 Cu. Ft. Compact RefrigeratorProblem: How do I adjust freezer temp in my mini-fridge with top frost free freezer, has turn dial for refrigerator but no turn dial for freezer and my ice cream is too hard... There is some strange "button" (I use the word button loosely, since it's just a piece of plastic that kind of depresses) behind the turn dial for the refrigerator, but there's no instructions as to weather that button is to be pressed 1, 2, 3 or however many times to get the desired temp or even if that's what it is for...
