Coming up to 14 years old, so has had a good long life so far.
Over the years, the fridge thermostat has been drifting, to the point where I have it at the lowest setting, and it is still freezing stuff in the bottom of the salad drawers.
This is a gradual drift, not a sudden failure.
Also, would it be better to replace completely? It is a category D energy efficiency, so presumably I can do a lot better now?
