I think the reason why fridges are so bad now is because manufacturers are chasing foods energy efficiency ratings. And to do so they basically put an underpowered compressor in it so that it uses less energy per unit of volume and achieves a better rating. The problem is that this drives the compressor too hard but just enough so that it generally fails after the warranty expires. That’s what I was told.
Same as how far manufacturers will make their cars heavier on purpose to achieve a better energy rating because the formula is basically engine power divided by total car weight. So a big engine on a small car has a worse rating that the same engine on a heavier car.
Anyway, another good tip I heard was to talk to appliance repair shops and ask them which ones they repair the least. And that’s the ones that are worth buying.

(I.e. an 8 kg washing machine used at 80 % = 6,4 kg or whatever other fixed percentage is more efficient than a 5 kg machine used with 4 kg = 80 % of washing – what the test doesn't care about is that if you keep the absolute amount of washing fixed, 4 kg in an 8 kg-machine of course becomes less efficient).
