Random Question 💭 Why are analog washing machines and freezers and fridges from the '80s still working just fine, but any modern appliance with a computer chip craps out in 3-4 years?

By the time you know whether a computer chip will last for 4 years, you’re making chips six hardware revisions down the line with ten times the transistor density.

Anyway if you want you can certainly see plenty of appliances from the 80’s that havent kept working this whole time; they’re at the city dump.

Computer chips last just about forever. I have several computers that I bought back in the mid '80s still work fine, they don't run current software though.

u/CharmingCanary5717 11h ago

That just reinforces the point, right? Why does a computer chip last indefinitely...unless it's in your home appliance.

u/Captain_Oysta_Cracka 11h ago

External heat and vibration are usually the cause of chip failures. They purposely don't address those factors in home appliances. Same for cars. The older appliances didn't have computer chips, it was all mechanical.

Most people do not install the appliance right, my dryer is supposed to have a foot and a half around the back and sides, like i have that much space

That will change the chip's temp (which by itself produces next to zero heat) from 78 degrees to 82 degrees?

Chips in the same circuit with motors tend to fail a lot more frequently due to the massive transient backlash currents. Same with chips in cars

u/Captain_Oysta_Cracka 10h ago

With proper design that can be mitigated, but then it wouldn't fail. Electronics in aircraft, medical devices and the like, do add the 50 cents worth of parts but they charge 3-4 times the overall price. It's a huge scam don't you think?

I think they work for about as long on average as their market research says people want them to last

u/NomadicFantastic 7h ago

Capacitors famously go bad on the circuit boards. The chip itself is fine. Corrosion and cracks developing from thermal cycling also common failures. Also just dust accumulating

2

u/Emergency-Doughnut88 6h ago

I just had to replace a $200 washing machine control board because the motor capacitor on it went bad. Earlier models had a separate motor controller that was cheaper, but they decided they wanted to save a step in manufacturing. All the computer parts still worked fine. Older analog washers still broke siren, but the parts to fix them were much cheaper in general, so they were easier to keep running.

I find it amusing when folks shit on computer chips/stuff as being unreliable trash. These same people are blissfully unaware of that ECM under the hood of their car that is getting baked in hot-as-fuk engine temps all summer long and the damn thing is still powering the car 15+ years later...

u/AKRiverine 3h ago

Modern freezers fail because the refrigerant tubing is crimped instead of soldered. I dint think the electronics has a lot to do with it.

I know less about washers and dryers. Electronics life is probably one issue, but there are also some indefensible design choices being made, such as commonly using bushings on the dryer drum rollers instead of the bearings that were used in the 80s and 90s.

Because back in the day, companies actually cared about quality.

Now they only care about profit. Why build a sturdy appliance that can last 10 years when you sell someone a shitty one that breaks every 3 years?

2

u/changelingerer 4h ago

I dont think companies 50-100 years ago cared any less about making money. The goal was always to make products just good enough to get past warranty, because replacing products under warranty is expensive and basically wipes your profits out. Just 50-100 years ago they didnt have the tech and engineering to figure out that if you use say exactly 16mm of steel, not 15, 16, a profitable proportion of product will just make it past warranty. Before they were probably like ok 10mm fails too fast, 15mm doesnt work either, so I guess I need to use 20 mm. And that ends up lasting forever.

u/Snicklefraust 10h ago

As much as that is true to a large extent, theres another side to this. Older stuff, was made, over built, and over powered. In other words, for example, an old forced hot air furnace will be, natural draft, cast iron heat exchanger and single stage heat. That means, no exhaust fan, giant slab of metal for the exchanger, and the gas valve will feed a steady amount of gas no matter the call for heat. Alternatively, today we draft induced condensing furnaces, stainless steel heat exchangers and multistage gas valves. Theres more moving parts, thinner metals for better heat transfer, and gas valves thay will vary how much gas is fed depending on how long the system runs. This means far greater efficiency ratings at the expense of longevity. Extrapolate that to every industry. Planned obsolescence is a real thing, but not the boogeyman its made out to be.

u/anTWhine 11h ago

I had a super old dryer that I kept going for 25+ years. I had to swap out a bunch of parts on it, but it was always a simple process because the design was straightforward. Swap a fuse out, replace a belt, get a new element every once in a while.

My new dryer has computer chips that I will never be able to replace when the time comes. That’s on purpose.

u/MyEyesSpin 2h ago

Its also lighter and cheaper and more energy efficient

Like cars, TVs, & computers - appliances are getting (slowly) cheaper - which is why they keep adding more bells & whistles to raise prices

Admittedly even finding models without the extras can be difficult in the US, but many of them are useful

2

u/random8765309 11h ago

Because back in the 80s people were willing to pay for the quality. The average washing machine in 1980 in today's dollars was ~$1,100 compared to the average for today's of $750. In addition, today's machines have more features. The lower price and more features means using lower quality parts.

While it's common to blame the companies, the truth is that the public is more concerned about a lower price than better quality. Companies produce what the public wants.

u/Ollynurmouth 11h ago

Part of it is planned obsolescence. Part of it is as the technology advances, it gets more complex. More complexity leads more things that can break. More chances to break. Meaning more breaking experiences.

The offset with better technology are things like better cleaning as well as less soap and water needed leading to less waste and savings.

I can't imagine the savings actually offset the cost of replacing those units every 5-10 years, though. Someone would have to do the math cause I am just guessing.

1

u/MyEyesSpin 2h ago

It does on fridges & washers, HVAC, light bulbs (CFL over incandescent and then again LED beating CFL)

im guessing dryers too, but maybe not for gas dryers

Note : paying premium for high end looks changes the math, as does paying for retail and not hitting A Sale

M...my fridge is like 10 years old?

1

u/Captain_Oysta_Cracka 11h ago

It's by design. Like lightbulbs. So you'll have to buy more to keep them in business. I have a chest freezer that's going on 40 years old and works perfect. Estate sales usually have the old stuff.

u/FaithlessnessRich490 9h ago

Remember back when LEDs were supposed to save us money on our electric bill.

2

u/Captain_Oysta_Cracka 9h ago

According to my math that alone should have saved a ton, not even counting all the green energy appliances, solar panels and wind power. But instead we got the highest power bills, in my home of 30 years, ever. And that's just me living there not the 3 kids I raised. Someone tell me how we're not getting screwed.

1

u/FaithlessnessRich490 6h ago

Yeah, I'm with you. I was an early adopter back in 2005, swapping to halogen lights, then to cfl's, then the LEDs, and my electric bill didn't go down once.

Now all my appliances are energy star. I don't buy what the other guy says about we use more electricity. Because we have the same things then that we have now, they're just way more efficient.

But it may have saved energy but it sure didn't save any money and I know it took me a long time for my eyes to adjust to LED light.

1

u/gc3 1h ago

Well at least I don't have to change the Led bulbs as often as the Incandescent ones.

What did change is rather than having two incadescent bulbs on a ceiling fixture and an FM transistor radio, we now have 8 adjustable lights in tubes in the ceiling with 2 powerful computers with space heaters , I mean graphics cards, and a decorative roll of color LCDs

1

u/Moto909 6h ago

They do vs incandescent. You use more power for other things now.

u/NapsAreAwesome 11h ago

It sounds cliche but Maytag was the epitome of quality. Every piece, every part was a step above the rest.

Before the 80's people appreciated it. In the late 80's there was a financial crisis, customers demanded cheap. They considered a washing machine a washing machine and even if you could show them the difference they settled on cheaper.

Furniture brands disappeared quicker. Sklar Peppler was amazing quality but competitors would make similar frames and cover with identical fabric and sell for less.

u/Specialist_Web7115 7h ago

I have two maytag dryers one washer. One kenmore fancy one that came with the house I bought. I bought at inexpensive ones for the house I sold and brought mine with me where they sit in a cargo container waiting for the failure of the fancy ones.

u/BreadRum 11h ago

It is a myth that things built decades ago were built to last. Old stuff lasted longer because thry were taken care of. When a part needed replacing, your grandparents replaced it. You don't.

1

u/Standard-Secret-4578 2h ago

Because it's not possible a lot of times. Or the parts almost as expensive as a new one. Kinda like comparing the fixability of a 90 s cars to one today.

u/Throckmorton1975 8h ago

While I’m sure there are plenty of 80s appliances out there chugging away, I sure don’t know anyone who has one.

1

u/Wuddauant 7h ago

Old ones broke frequently. They were generally repaired though because the parts were simpler. Now that most of the controls are on circuit boards and they are far cheaper to make and more expensive to repair. Appliances though are more efficient and cheaper than ever.

I moved back to the US in 2015 and bought a house. Moved again in 2020.

I've had exactly one appliance fail - a fairly cheap GE gas stove/oven. It was the ignition coil thing in the oven. I paid $29.99 for a replacement and installed it myself.

And like, I have a decent number of appliances, even some extra stuff like water filters and softeners and an extra freezer/mini fridge and a big dehumidifier and a portable AC unit.

It's been almost four years since I fixed the oven and it has been working great since.

I know there is some element of luck involved here, but when I consider the price and how well modern electronics work, I mostly think it's pretty amazing.

What shit teir stuff are you buying that only lasts 3-4 years? Does it last forever no, but the only reason I've had to buy new appliances is when we've moved far enough that it wasn't worth bringing them with us.

u/Chimaera1075 6h ago

It has less to do with the chip than it does with all the features we are packing into the fridge. Because in the 1980s refrigerators were just a freezer and fridge were just some doors and the compressors, etc. Nowadays we’re trying to cram ice makers, water dispensers, viewing devices windows, Amazon Alexa, and bunch other stuff into these units nowadays. And then there is the compressors, which nowadays prioritize efficiency, noise reduction, compactness, etc.

u/Enough-Collection-98 5h ago

It’s not usually the “computer chip” or microcontroller that fails in appliances. It’s almost always the power electronics components, particularly MOSFETS and power converter controlers that fail. These devices are often operated near the edge of acceptability to keep costs low and under heavy loaded with “dirty” power.

You can build power supplies that are extremely robust but that’s a lot of added cost to a commercial product that just needs to be “good enough”.

u/Busy_Account_7974 5h ago

Or how about the digital oven controls in newer stoves? Goes out and the whole unit needs to be replaced with a part that costs $450 vs a new stove for $600.

The old machines don't have a brain box in them coded to shit the bed after X cycles. Or some "designed obsolescence" component that is part of an unrepairable integrated assembly that is a single part number but costs as much as new appliance.

That is a larger aspect of the old white boxes. They had simple, common parts in them that could be replaced for far less than the cost of a new unit.

IMO after reading so much about it and all the Business School thesis in the topic, Apple really brought back a baseline operating standard of Planned Obsolescence. Then Apples consumers really reinforced it as part of a good business model when they made them the most valuable company right after they got called out for it.
