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.
Each defrost cycle can last up to 30 minutes. During the defrost cycle, the compressor and evaporator fans are turned off. A heater under the evaporator turns of and melts the ice and frost off of the evaporator. recommend measuring your normal operating temperatures in the refrigerator and freezer by the normal methods noted above. This refrigerator has an Adaptive Defrost Control board that initiates defrost cycles as needed between 6 and 72 hours apart based on compressor run times and other factors.
