Incidentally, I happen to have almost the same refrigerator as the author (same thing, but without the hot water dispenser). My only failure so far has been the condenser fan after seven years of operation. It was clearly an electronic failure of the onboard motor controller, which honestly has no excuse to fail.
I also have a more-recent Kitchenaid 48-inch-wide side-by-side purchased in 2020. It's a remarkably simple appliance given the year of manufacture. Yet the interior lighting is horribly unreliable. The freezer killed three lighting modules in its first three years. They inevitably go high impedance, usually emitting zero light. One of the three was still emitting a tiny amount of light post-failure. The lights are all in series, so when one fails the entire chamber goes dark. I've even had one of the replacement lighting modules fail already. This component is clearly flawed and I'm tempted to design my own replacement.
