What is the difference between auto defrost and frost free?

There are 2 sets of terms that can confuse potential fridge freezer buyers, but are very simple to grasp. By understanding the difference, you’ll be able to choose a model that best suits your individual needs and price.

Auto Defrost
This term relates to the fridge only. Condensation that forms on the back wall of your fridge can turn to ice and affect both the preservation of your foods and the running of the appliance. The auto defrost function works by heating the cooling element for a short period of time, melting any frost that has formed. This is then drained through a collecting duct located at the back of the unit. This is an extremely common function and should be found on all fridges.

Frost Free
This term relates to the freezer compartment. Through the use of an internal fan dry air is circulated around the cold cavity which prevents any ice which may have formed and works independently from your fridge. Thanks to this invention no time will ever be wasted on defrosting, and you’ll always maximise potential freezing space. Foods will also keep in a much better condition, and individual items like sausages or chicken breasts will be easy to separate. This function isn’t available on all models, and there is a slight price increase in those that have it.

Total Frost Free/ Total No Frost
If an appliance claims to be a total frost free appliance then it will combine both features, ensuring you will never again see the sight of ice. You may have to pay slightly more, but the benefits are constant. Ice build up can turn an A+ appliance into a D rating over the months that it continues to form and expand. The benefit of this joint function ensures that the appliance will constantly perform to the high energy rating it was awarded.
