What would cause the cooling panel at the back of a fridge to expand a
couple of inches into the food compartment? You can see it in this photo.
The bowing over most of the large cooling panel at the rear is NOT a curved
part of the design.

The panel expanded within 24 hours and pushed the top shelves out of their
supports. It's a BEKO model CF5015APW.

Has something has happened within the cooling element itself?
