Doors to freezer and refrigerator mysteriously warping

What would make the doors on this refrigerator buckle like this?

We just had the same thing happen, so I’m currious as to why this would happen also.

My Father pulled the Refrigerator/Freezer away from the wall to clean underneath it and when he put it back in place, he noticed the freezer door had warped/buckled.

In your picture, it looks like a similar, if not the exact same model.
