Hi Donkey! Depending on the set temperature and length of cook time, the door may become warmer than the room temperature. However, if the door ever became too hot to touch, we would ask that you reach out to us so we may work together to find a solution. You can reference ticket number 1142835477, and reach us through either Facebook Messenger: http://m.me/samsungsupport; or Twitter: https://twitter.com/messages/compose?recipient_id=18768513. ^Jecca
