Answer 1

In older refrigerators it would cause a lot of ice build up due to the steam of hot food hitting the cold walls of the refrigerators.

In modern ones depending on the cooling technology used it’ll cause them to temporarily raise the temperature and consume more power or even affect other products in the fridge which in turn will go bad, think of fresh salad or fruits for example.
