edit: you can see this in action right now. There's one glowing review of whirlpool and one scathing review. I'm sure they're both honest, but what conclusion are you going to draw from that?
On the other I don't know of a better one ¯\_(ツ)_/¯
n=80,300, but paywalled. However, one interesting tidbit that isn't paywalled is how bad fridge reliability is
>Our results reveal that about a third of all refrigerators require repairs by the end of their fifth year of ownership, making them one of the least reliable appliances we analyze in our member surveys.
A basic fridge like this will last you a long time: https://www.costco.com/whirlpool-20-cu.-ft.-top-freezer-refr...
If you really want all the reliability money can buy, buy a subzero fridge. But you're paying 10x for the same functionality (unless you really need extremely stable temperatures).
Reliable after 40+ years of refinement and dead easy to troubleshiot.
I'm probably trading my piece of crap KitchenAid (Whirlpool) for a Bosch 800 pretty soon. Never get a french door fridge from Whirlpool.
