A:AnswerThis unit does not show degrees, it just shows Maximum Cold to Minimum. I keep my unit set to Maximum. Don't worry about setting the degrees to avoid freezer burn -- that's caused by the length of time the item is frozen, not the number of degrees in the freezer.
A:AnswerHi! This model is not frost free. To manually defrost your unit, you can review page 20 of the user manual available on our website.
