Applicable to Large Units only.  Unplug unit, add towel underneath unit, leave the door open and let the unit sit for 8 hours. DO NOT scrape off the ice as it will damage the unit. Let the fridge sit unplugged until all ice in the freezer is melted into the drip tray. Remove all water from the unit, including in the drip tray (located under the freezer- this is very important).
