GRR - it's newish, just over two years, supposed to auto defrost...
Fed up with having no idea what's in there, never able to fit anything in.
I've spent three hours defrosting it, putting bowls of boiling water in to loosen up the chunks of ice, keeping the cat who wants to help out of the way. Still not finished.
And it's not huge, externally 50cm wide and probably about the same height
