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.
During a defrost cycle, melt-water from the freezer ice typically drains through a tube and down the back of the refrigerator into the drip pan. You may hear water dripping into it or it may rattle. Usually evaporation empties the drip pan, but you can remove it and empty it if there is a lot of liquid in it.here is not much under a refrigerator to make noise. You may hear noise coming through this area of the fridge, but it is probably originating in the back of the refrigerator. Regarding any water sounds, refrigerators have a drip pan behind the kick plate.
