Defrosting (or thawing) is the melting of an object or bringing a device's temperature above the freezing point to remove ice. A defrosting procedure is generally performed periodically on refrigerators and freezers to maintain their operating efficiency. Over time, as the door is opened and closed, letting in new air, water vapour from the air condenses on the cooling elements within the cabinet.
