Wow, the OP must think there is a reading comprehension problem on the forum. LOL
He wants to keep the door ajar, i.e. slightly open, but it's parked on an angle and the door comes completely open. So far only one person has offered a possible solution: bungee cord. My vote is to put a chair or stool in front of the door to stop it from coming fully open. A towel put between the doors will keep the freezer door even with the fridge door.
And the OP hasn't returned to answer our question about why they can't be fully open.
