OMG, the "features". My stove is relatively simple except for 1 part, the one that sets the oven temperature (and the time, but who the hell needs a third clock in their kitchen). That part is a 300 dollar, proprietary circuit board. Of course it's the first thing to go. I'm sure the board doesn't cost the maker anywhere near $300 but I'm sure it's a lot more than an industry standard knob. If they want to cut a few bucks off the price, there's a good place to start. Put a standard knob only stove on the showroom floor and it might not be the first appliance everyone purchases but it will the be second of anyone that realizes how stupid it is to have a computer where single function piece of hardware belongs.
I don't know about that particular example, but refrigerators with ice makers are an obvious case of people buying appliances way more likely to break down.
In my case it wasn't the ice maker itself, but the plumbing leading up to it within the refrigerator. I finally ended up turning off the water supply after my DIY repair broke a second time.
You can save a lot of money on almost anything if you're willing to get your hands dirty and do the work yourself. I don't think it invalidates the argument.
You're totally right. I was trying to weigh the convenience and time savings of automatic ice for 12 years vs the low cost in time and money to keep it working, but I only cited the latter in my response.
