well ive never personally seen one of those particular mini fridges, but generally those types of mini fridges have doors that are removeable so you can adjust it and make it open whichever way you want.
If it has one of these types of doors, then there couldn possibly be anything in the door that you could hit and damage and it is completely safe. even if the door isnt removeable i could say pretty positively theres nothing in the door to damage anyway
