Cost over its typical lifespan

Is it worth replacing?
The Miele KFMC 3846 R runs above its category average. If the refrigerator you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $109/year every year.
Compare current ENERGY STAR certified refrigerators before buying.
Protecting what you have
A refrigerator like the Miele KFMC 3846 R is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
