From Wikipedia, the free encyclopedia. Auto-defrost, automatic defrost or self-defrosting is a technique which regularly defrosts the evaporator in a refrigerator or freezer. Appliances using this technique are often called frost free, frostless or no-frost.
Auto Defrost vs. Manual Defrost. Fridge temperature is hard to regulate, so defrosting your refrigerator and freezer is inevitable. Appliances come with either automatic defrost or manual defrost options, and there are advantages and limitations to each. Both are used to accommodate for temperatures that fluctuate out of the preferred range.
