How To Defrost Defrost the freezer compartment when the ice / frost are approximately 1/4 " thick or every 3 months, whichever comes first. Set the thermostat dial to " 0 " to defrost. Remove all contents from the freezer compartment. Leave the freezer door open to allow accumulated ice / frost to melt. Remove large pieces of ice as needed. Do not use hot water or other electric heating devices to melt the accumulated ice. After defrosting, remove accumulated ice / water and wipe the freezer compartment dry with a soft cloth. In the event that the ice is not visibly present in the freezer compartment, please allow the evaporator located behind the freezer wall to completely defrost for approximately 2 hours before restarting the unit. Restart the unit per starting instructions. 8
