There’s some appliance breakdown vids (idk if Rossman is one of them) but the gist is Samsung and LG like to put cheap plastic parts in high wear locations which inevitably fail.
Fridges are dead simple appliances. A compressor and evaporator coils with a temperature sensor. There’s absolutely no reason they shouldn’t outlast you and everyone you love.
It’s insane these “premium” brands are built to fall like they do.
An insulated box with a decent compressor does not cost 10k. Making a compressor that fails after 2 years is actually hard to do, something both LG and Samsung spent time and money to achieve.
Consider, for example, that nearly every car manufactured with an AC. Which is exactly the same tech as a fridge. Yet you rarely end up needing to replace the compressor on your car. You might need to recharge it or clean it, but not replace the compressor. 10k of your car price isn’t the HVAC.
