Wow! That is why you buy a Sub-Zero. They are built to last. New ones are much more efficient as well. I would say let her run, but don’t put any more money into it at this point. Not worth it. The space has not changed so it would be good to buy a new one. But if another Sub-Zero is not in the budget, KitchenAid and others offer built-in fridges of that same size.
