Yes, but how often do you experience power outages or other things that lead to weird temperature changes? I think in the last 15 years it only happened to me once.

And how often does a fridge door open on its own? Most people don't need other people (or things) to remind them that they should tie their shoes before getting out. If you don't need that, I assume you know you should close the fridge door.

In Ukraine last year we had scheduled blackouts. Let me tell you about the joy of waking up every other night to reset temperature alarm of the fridge. It could not be disabled, and it would beep for hours. My neighbors were not pleased when I was not at home for a week.
And that cheap beeping sound of every appliance is just so obnoxious. You want to wash laundry overnight to lessen load on electricity generation during blackouts? It would beep for 30 minutes when it is done. No way to disable it but to wake up and turn the button. When everyone does it, the whole apartment complex is filled with beeping sounds all night.

I prefer the sound of air alarm now.

You must not live in Texas or California.

You're a lot more upbeat on current fridge reliability than I am. LG lost a class action suit regarding their junk "linear" compressors a few years ago, and despite multiple supposed revisions you can still find appliance repair folks badmouthing their current crop of linear compressors on youtube. To the best of my knowledge, my vile LG ex-fridge didn't have a linear compressor, but it did have a habit of icing up the evap coils until the fucking thing couldn't keep the temp down. LG sent a tech out twice, he couldn't figure it out. I got tired of throwing out food and tired of ice buildup hitting the fan and making an absolute cacophony in the middle of the night… so they finally bought it back.

I've seen some grumblings that the switch (in the US) to R600 is killing durability, but I'm not sure I buy that. If you dig through some of the service literature out there you'll see that companies across the board are also cheapening the sealed systems (e.g. aluminum replacing copper).

  you know you should close the fridge door.
A common complaint about my current fridge is that the doors do not close on their own. The detent is wicked strong. I suspect you'd have to tilt it back to an uncomfortable degree to overcome it. E.g. the door probably wouldn't stay open at all on its own.
Its not just their linear compressors, its the fact that they use very thin aluminum tubing on the high side, and apparently have had assembly issues where weld material has splattered on the tubes, which after a bit of thermal cycling (or maybe its just galvanic corrosion) they start leaking.

I to had a LG refrigerator declared "unfixable" and bought back by LG, but I actually decided they were idiots and fixed it myself after having not only their local repair people fail to fix it, but the "expert" from LG's regional center come out and diagnose it. (It should be noted that he diagnosed the condenser, the only part not already replaced at that point, and that failed to fix it so, they declared it unfixable).

Turns out in my case, the leak was in the yoder loop, a modern trick for increasing the efficiency of a refrigerator by running a high pressure refrigerant line around the doors to avoid needing electric defrost loops (what pretty much every fridge made pre ~2005 or so has).

And since the yoder loop is embedded in the spray foam insulation between the exterior and interior of the fridge is is largely unrepairable because the insulation would have to be destroyed and somehow partially refilled, which wouldn't be possible without adding a bunch of access holes/etc to the exterior.

So, I bypassed it, as a "research project" before buying another fridge, something the LG folks told me wouldn't work, and the tech refused to do. Which funny enough i'm an EPA certified small appliance repair tech (don't ask! lol) so, it apparently is just up my alley. And guess what 5 years later is still going. I've had to manually defrost the ice maker fan once in that timeframe and it does tend to get some condensation build up on the bottom of the french doors, but nothing that wipeing it away every few days doens't solve.

As an additional bit of fun, this refrigerator has a steel condenser and both aluminum as well as copper tubing/fittings.

Yeah I had a top freezer model, something that should be dead nuts simple and yet everything was still electronically controlled. That means you've got all sorts of onboard diagnostics. Even so the LG tech couldn't figure out the problem. In general though I can totally get why someone employed by the manufacturer wouldn't want to go off script. Too much liability.

One of many problems with LG is that they seem to have a rotating cast of metrics driven clowns running LG America. Junking a fridge is almost certainly more cost effective than spending the time to fix it, train their techs in depth, and get their logistics in order. The tech that came out had previously worked for GE and had worse things to say about their brand of chaos.

Funny enough the Whirlpool that replaced it did have exposed insulation (and gobs of epoxy everywhere). It would've been worse than the LG, except it actually kept things cool.

So it was unfixable, without disabling an essential feature?
The yoder loop on a fridge is designed to prevent condensation near the door seals. Depending on your climate you may be able to get away without one.

When I'm talking about the heater on mine not working, I'm talking about the heater for the evaporator. Without a working heater I'd get enough ice built up on the evaporator within a week to cause problems with the evaporator fan. If the fan doesn't work you're not gonna get much in the way of cool air into the fridge or freezer compartments.

You didn’t mention the evap heater. What could LG have done differently to fix your fridge to factory spec?
Pretty much everything else could be done differently:

- Calling in a warranty claim involved going through a troubleshooting script that wanted me to do things that my fridge could not do. LG needs to get their documentation in order so that their call center staff can at least approach being useful.

- LG punted me to an authorized service center first thing. I'm in the Bay Area which should, IMO, be a large enough market to have sufficient LG direct staff. LG needs to hire more repair staff.

- The third party ignored me for a few weeks and then I started making noise in LG's general direction. LG probably needs to up their warranty rates to entice third parties to actually service these calls.

- LG finally sent one of their techs out. He called me, I described the symptoms and the temperature graphs to give him an idea of what's going on. He finally admitted that he didn't have ANY parts for this fridge on his truck. So I told him to order what he thought needed. That took about two weeks. On his first visit he identified more stuff he wanted to replace so that took another few days because the west coast distribution center didn't have the parts and he missed the cutoff for the east coast center. LG needs to get their American logistics in order.

- LG pushed really hard to get the tech out here ASAP even though he had some idea as to what was wrong and was in no position to fix anything. LG ought to stop relying so heavily on useless metrics.

It's been a long enough time I don't remember the precise symptoms and I've no idea what actually failed beyond a thermistor so it's impossible to suggest engineering improvements. However I think LG ought to work on training their own techs to get their diagnostic skills up to snuff.

Although I'm pretty sure it's not one of LG's horrific linear compressors, I suspect the compressor failed or there was a refrigerant leak. Unlike the above poster I've working knowledge of automotive A/C not small appliances. In a car the refrigerant will carry the lubricant, so a refrigerant leak can indeed cause problems as the compressor eventually runs dry. For all I know the fridge's compressor uses an oil free design and failed for other reasons. I think the tech checked temperatures at the condenser and was happy with that – but remember unlike on a car refrigerators have no ports to check pressures. That's crucial in diagnosing problems, so techs are kinda flying blind here.

If the problem was with the sealed system then the solution is: LG needs to engineer their fridges properly. Fixing the sealed system in the field is something you can do (except for the yoder loop in the insulation) but it takes time and skill, things that most techs don't have. Basically those repairs won't last. Working with aluminum (welding, brazing, soldering) is tough, although I think LG is moving to using fancy compression fittings for repairs.

If it's basically anything else they need to again work on training their techs to diagnose these things properly.

Probably a tiny handful of times? And would it have been useful? Yes of course it's useful to get a warning when you're not at home or upstairs in bed. I didn't say it was a life changing critical feature, I said "handy".

We had a freezer door pop open overnight once... it was because one of the drawers wasn't quite shut properly, all was good for hours after closing it and then suddenly it popped open when we were in bed and we came down to the food at the front of the drawers defrosted.

When you use something day in day out for 40+ years you occasionally have an accidental bad interaction. Sometimes you press the wrong button on the TV remote, sometimes one of the drawers in the freezer is further forward by half an inch on one side and you didn't notice, it happens.

Most people, especially on HN, don't need to be reminded to think critically about how real world interactions actually might occur before posting poorly thought out responses for the sake of evangelically pushing a point, but here we are

I'm not saying it is not useful, nor am I making a point about "survival" (also because people have survived long before fridges were even a thing).

I'm saying it can be useful, but only very rarely.

Features that are useful but only rarely are great. Designing only for the happy path is terrible.
only if the downsides are less significant.

If dealing with an ugly path means streaming data all the time to the Internet and potentially decreasing the reliability of the whole thing, just because once every 5 or 10 years stuff defrosts...

> how often does a fridge door open on its own?

No, it's for when the kids leave the door open or just don't close it properly - which is VERY frequent. The door alarm goes off once per week here, at least.

Yeah but kids can do all kinds of stuff. If your kids start drawing on the wall, do you have an alarm for that? Or for when they break a glass?
Kids can know to close the door, intend to close the door, but still fail to realize they didn't close the door. They're kids, it happens. And its a simple feature that can help realize the door is still open. It's not that deep..
My dog is my alarm for when the kid starts drawing on the walls or breaks something. He barks to let me know. It’s very convenient and I’m glad to have him. If it was practical to make a computer to do this I’m sure people would find it useful.
