Thermal cycling is one of the biggest stressors electrical components can be subjected to. Leaving your processor on and at a consistent load massively improves the lifetime of the chip. So take THAT, mom!
Fridges 100% die, they're made to now. If your fridge is really that old and you can manage it, NEVER get rid of it, tell your parents to leave it to you in their will lmao.
Fridges actually do rest. They cycle on and off as needed to maintain their desired temperature and on average only spend about 30% to 40% of their time "on".
My wife and I are on our third fridge in 35 years. But the furnace in her mom's house when we sold it 5 years ago had been running since the late 1970s.
heh. my 15 year old frigid started making random groans the last couple weeks. far enough apart that i couldnt figure out where it came from. got lucky one day it moaned while i was close enough to yank open the freezer and see where the lever for the icemaker had accidentally got flipped to the on position. since i hadnt hooked up the water line to it, the groan was the pump sucking vacuum
Lol I had to look up the year that happened because yeah, my fridge is roughly that old. It was the fridge we got when I was a kid and now I have it at my house. I'm planning on it working until I'm dead.
A thousand refrigerator psychers must be sacrificed so the frig emperor can live on in perpetual conflict with the gods of chaos: Frigidaire, whirlpool, Samsung and Slaanesh!
We've had a GE fridge that's probably older than about 10 years. But you know, it's complicated enough that it feels like it's made to fail at some point.
Well, stuff stopped cooling but all the lights were on and everything else worked. It was really weird. We were thinking it might be a dead compressor or something. Crap, do we need a new fridge?
Nope! What basically amounts to a glorified computer fan with a fancier proprietary plug does all the work of distributing that cold air through the rest of the unit.
The proprietary plug is totally so they can sell it for $45, of course. Lol anyway, works like new!
Also get a dust mask and vacuum + blow out the back of your refrigerators, people. They get grooooss!!!
Having a fridge running is nothing complicated compared to a computer. The compressor and the light inside are the only things that are being powered. Both components work mechanically: The compressor has an electric motor that is running when fed with electricity. Pistons inside the compressor are linked mechanically to the electric motor. The light inside the fridge is operated with a switch that is mecahanically connected to the door. The light is off when the door is closed.
As long as electricity is fed to the fridge, it keeps running.
Computers however are more complicated, as they basically are running clocks that connect an event with a time stamp. They can get disturbed easily when several events happen. When a computer is running long enough it can happen that the memory overflows when a specific event is being executed for example. For this reason it is renommended that your smartphone is supposed to be restarted at least one a month, otherwise it couldn't function properly.
If refrigerators were operated the same way as a computer, like your laptop or smartphone, I bet it has to be restarted every once in a while, otherwise a malfunction would occur. To my knowledge refrigerators are built the same like 40 years ago, albeit with more efficient compressors, better insulation and less harmful refrigerant.
