While it should not occur with proper operation, a frost-free freezer might become icy inside. Getting rid of the layer of ice inside the freezer helps it to run more efficiently. Avoid the problem by keeping the door to your freezer tightly closed at all times. Especially in humid climates, leaving the door open for too long could cause frost to form on the inside walls and door. If you do have to defrost your frost-free freezer, prepare for a wet process, but one that can save you the cost of expensive repair or replacement of your freezer in the long run.
Remove all of the food from inside the freezer and place it into the ice chest. Use more than one ice chest, if necessary. Cover the food with ice from a 4.54kg. bag of ice. Alternatively, place all of the food from your freezer into the refrigerator compartment, packed tightly together.
Place one or two 4.54kg. bags of ice into one or two large bowls inside the refrigerator compartment to keep the food chilled. Keep the door to the refrigerator tightly closed and avoid opening it during the freezer defrosting process.
Unplug the unit and leave the freezer door open.
Let the freezer defrost overnight or for at least eight hours.
Use the towels to wipe up the melted ice.
Plug in a hair dryer and direct it to the interior of the freezer to melt any remaining ice from the walls and door. Be sure to direct it into the vents of the freezer, too.
Wipe up any water from ice melted with the hair dryer from inside and around the freezer.
Plug the freezer back into the outlet, and return food still solidly frozen to the freezer compartment from the ice chest or refrigerator. Use any thawed foods within a day or two or discard.
