>>> "Does anybody have insight on what the best(reliable) induction ranges are these days?"<<<
Unfortunately, there does not seem to be anything known to be more reliable than the GE models. (Maybe I should say anything known to be less unreliable?)
This problem got me musing (yet again), about the conundrums of choosing a range for the long haul. They lead me to increasing pessimism generally about longevity of appliances in general and specific pessimism about finding other brands of current induction ranges with better reliability than than the GEs which are the subject of this thread.
Doesn't my introduction sound nicer than saying I'm about to launch off on a rant about what seems to be an overall decline in the reliability of all appliances that rely on electronics? :>)
Still, the proliferation of electronics is a problem and not just for induction stoves. Given that induction stoves have more electronics than most, it seems they are more vulnerable, but we really do not have any accesible information that shows they are worse than other kinds of ranges.
That said, we know it is possible to build durable and reliable electronics that will survive a lot of stress. The military gets them (albeit with maintenance and replacement contracts) and we certainly have had automotive engine compartment electronics that last decades.
It is received wisdom that consumer electronics seem designed to have short lives. Mostly not seen as a big problem with computers and smart phones because of the pace of improvement. For my video editing workstation, for example, the computer, monitors and software that I bought five years ago were (and still are) great for the HD video cameras I used. But, now, we're moving into shooting UHD video with four times the resolution and and four (and more) times the data rates. I now need a new system for the dramatically improved capabilties of the new cameras. So, if my old system were starting to fail, no big deal since I'm already going for new equipment, anyway.
Not so when it comes to my kitchen. While some of the current crop of induction cooktops and ranges might seem a little better (in some ways) than the induction cooktop I bought five years ago, the differences seem to be minor conveniences --- at best. I have no reason to want to replace my stove or cooktop. I'm planning/hoping on my current induction cooktop lasting me ten or more years.
Is that a good hope? Hard to say. I fear not.
For guesses about probable durability/reliability rates, we used to be able to get some helpful information from the annual membership surveys conducted by Consumer Reports. CR still conducts annual membership surveys, but it lumps all kinds of electric ranges together. There is no break-out for induction ranges.
Also, the CR survey now asks for breakages in the first three years of ownership. It used to be five years. (Not encouraging, eh?)
In the fine print on the survey page for electric ranges, CR says that their survey results only include "ranges not covered by a service contract." Presumably, then, they are excluding range covered by extended warranties. One wonders why? Does not that exclusion seriously skew the defect rates that we are interested in?
CR's surveys formerly showed the GE defect rate for electric stoves for a long time running at around a 5% breakage over five years (which presumably included ranges serviced under extended warranties). The current, redesigned survey is now showing 9% breakage rate in the first three years of ownership and excludes ranges serviced under the extended warranties. CR says that it has changed its survey methodology so the rates are no longer comparable. That certainly seems discouraging about the data's usefulness to us, eh?
The current worst rate, according to CR's latest survey, is for LG electric ranges with a 15% breakage rate over three years followed by Samsung electric ranges showing a breakage rate of 14%. Leaving aside the question of whether folks who buy GE ranges are more likely to buy extended warranties than the folks who buy LG and Samsung electric ranges, all the other reported (major) brands are running between 11% and 13% rates overall for their electric stoves. The fine print on the CR survey data page says that differences of 5% and less are "not meaningful." The message seems to be that you will do better choosing a GE electric range over an LG electric range, but it is pretty much a crapshoot in choosing between GE and most other brands of electric ranges.
The CR survey apparently did not get enough responses for any meaningful statistics on brands like Dacor, Wolf and Miele, but there is little reason to believe that those brands' electronics are significantly more durable than for major brand induction ranges.
Miele reputably builds appliances for twenty-year life-spans, However, it only provides a 5 year extended warranty. (In Canada, you can extend that out to ten years.) What speaks well for Miele in that regard is that the warranty even covers electrical system damage such as surges and lightening strikes. Seems like considerable faith in the durability of their electronic systems, eh? So, one wonders why US buyers can't get the ten-year warranty offered to Canadian buyers? Well, for one thing, Canadian buyers pay a lot more for their Miele induction ranges. Base price (sans extended warranty) in the US is $7k. Base price in Canada (sans warranty) translates to around $8400US. Hmmm, maybe not so encouraging, after all?.
Anyway, the Miele may not be significantly more reliable. Miele designs its appliances to be repairable. It sells the appliances at such high prices that it can seem reasonable to make repairs that would seem uneconomic on less expensive brands.
Consider what you are likely to do if your 5½ year old induction stove's controller boards were to fail. (This seems to be the common problem identified in this now two-year-old thread.) Consider a Miele which you would have purchased for $7500US (with the 5 year extended warranty) as opposed to, say, a Frigidaire FGIS3065 slide-in induction range for which you could have paid around $1400 or a freestanding GE PHB920 for which you would have paid around $1700. (I"m leaving out the cost of the extended warranties for those, but guessing that the cost might be around $200.) Granted that Miele parts are going to be much more expensive, you would likely repair that $7500 Miele even if the new boards cost $2000. But, if you were looking at, say, $1200 to $1400 to replace the control boards in your $1700 GE or $1400 Frigidaire, you might well decide to dump the broken 5½ year old range and buy a replacement range. This situation can make Miele stoves seem more long-lived than GE or Frigidaire stoves without the Miele range actually being a more reliable stove.
Early failures are not automatic for everybody, of course. Some ranges will fail in a few years and some will go on for a long time. My cousins have a thirty-something year-old Kenmore induction range (which my aunt bought in the 1980s). It is still chugging along as is the one purchased by a long-time gardenweb poster (whose name is escaping my aging memory at the moment.) For every story like that, however, there are plenty of others whose old Kenmores did not last. We have no way of knowing whose stove will last long and whose will not.
Worse, we have no way of knowing the actual odds of longevity. If 10% fail in three years, that would mean 9 out of 10 would last longer. But how much longer? Do half of them fail by six years, nine years, twelve years? We presently have no way of knowing? You can sometimes gather some small sample from posts on, say, the Yale Appliance blogs. (Again, though, that is in pretty broad categories, such as how many service calls they get for a brand's stoves or washing machines or fridges. No real breakout by models or types.)
It used to be that appliances were expected to last longer and the expected costs of long service were built into the prices charged for them. It seems that manufacturers are now going for a la carte pricing. One could say, in economic terms, that they have shifted the costs of warranties and product longevity into insurance that they make you purchase separately at your option. That makes for uncertainty about how serious they are in building durable goods that are, in fact, durable.
This uncertainty led long time poster Kaseki, after his induction cooktop died at seven years, to suggest looking at induction appliances as lease transactions rather than purchases. Take the cost of the appliance (and extended 5 year warranty). Divide it by five years to compute a cost per year. Consider if you would be willing to lease a stove for that yearly amount. Say, you can get a GE PHB920 range and extended 5 year warranty for $1900. Would you be willing to lease an induction range for $380 a year? If it lasts for 7 years, your rental cost has gone down to $271/year. Would that be acceptable? If it lasts ten years, the annual rental would be $190/year. Would you be willing to pay that for a good stove? 3katz4me added a corollary suggestion to buy one of the less expensive models of induction ranges so that rental costs seems less financially onerous. (Kind of like leasing a Subaru instead of Mercedes, maybe?)
All of the foregoing is not confined to induction stoves. Control boards are proliferating throughout most models of most major brand stoves these days. Same thing with fridges, too.
This is all a very long way to saying that extended warranties are probably necessary and also an explanation for pessimism about finding any brand of induction stove that will actually have meaningful durability and reliablity greater than the GE products.
