You can still get new fridges that will last for decades. It just won’t be one with LCD screens, ice machines, in door dispensers, complex internal designs, etc. Every one of those things simply creates a cascade of new points of failure, and component materials of varying ability to deal with the stress of being a fridge. You can buy new, efficient, fridges that are nothing but a box that cools, and a box that freezes, with doors. They will last for decades if you don’t do anything crazy, or your house isn’t destroyed by a natural disaster.
