Remove all of the food in both the main refrigerator and freezer portions of the appliance. Plan to either store the items in a large, ice-filled cooler or to consume them that day.
Turn the main refrigerator dial to the defrost setting or (in some older Kenmore refrigerators) to "Off." Open both the refrigerator and freezer doors. Place a large pan surrounded by towels beneath the freezer section of the refrigerator.
Place a pan of hot water inside the freezer section to hasten the defrosting process. As the ice begins to melt, regularly empty the pan beneath the refrigerator of water and promptly mop up any excess with large towels.
Wipe down the refrigerator's walls and surfaces with a mixture of mild detergent, water and baking soda after all the ice has melted. Dry the entire inside of the refrigerator thoroughly.
Turn the refrigerator back on. Close the doors and allow the appliance to return to its set temperature. Replace all food items only when the refrigerator is cool enough.
