Your chair and your fridge, like a piece of software, can be repaired or fixed. They get worn down, especially if they're repaired many times over. Crashing, in the context of a chair or fridge, or in software, is generally not seen as a catastrophic failure which fundamentally makes the chances for repair or fixing impossible.
One would hope your chair or fridge never "crash", like one hopes a piece of software never does, but they come in all levels of quality and face all kinds of edge-cases. One day, for instance, maybe a 3 tonne man sits on your chair, which has held you up just fine every day, and the chair fails to hold him up, crashing him to the ground. You wouldn't turn around and reasonably say your chair is now a failure, really.
