Or perhaps more accurately, to stop poking a giant hole in the ozone layer.
They can be easily fixed, and parts are still available - unlike my Mom's 5-8 year-old Samsung and LG appliances, which will have to be thrown away and replaced soon, because parts are NOT available. As for efficiency - they're not really much less efficient than new ones, especially when you figure that each of them has outlasted a half-dozen or more modern appliances.
When the washing machine tub cracked a couple of years ago, I asked the local parts shop if it was worth getting our old Kenmore(Whirlpool) machine fixed, and when he found out it was from 1987, the manager said, "Don't ever get rid of it! You can't buy anything made that well today at any price!" So I spent $80 on a new tub (plus $75 for labor, since installing it is a pain). That's one of only two major repairs it's ever needed (I swapped out the synchronous clock driven cycle controller myself 15 years ago) - it still runs just like it did when new.
It's certainly possible that all my appliances could outlive me...
You had to manually defrost it for it to keep working. Modern ones have automatic defrosters and other such features.
Yes, the old one "kept working", but at worse-and-worse reliability as the frost built up, until you manually removed everything from the freezer and ran a proper defrost cycle (aka: turn it off, wait for everything to melt, sponge out the water).
I think I'll stick with my "less reliable" heater-inside-a-freezer with an escape hole to automatically siphon + pump the water out. More moving parts means less reliability, but these features are absolutely worth the loss in reliability.
My current kitchen has a microwave that's from the early 2000s, it works fine and has exceptional even heating and top notch auto sensor modes. The 1980s one we had was a total hunk of junk that constantly had failures, wasn't as powerful, didn't have any sensor cooking modes, and performed very poorly at cooking evenly. The other microwave from the 90s ate fuses for breakfast and had massively unreliable sensor cooking modes.
So for me, practically all my newer appliances are way better than the old ones and have still often lasted >10yrs. Anecdotes are anecdotes.
Sure, if you only consider all the older appliances that have survived this long.
