Oh, I know it's entirely my fault for letting it be inactive and all, I'm not blaming them.
It IS unfortunate that there's both a fairly high barrier to entry AND apparently no real way to recover older accounts.
It's hard to justify the time investment to improving an existing answer on stackoverflow, when I've already posted it to Youtube and that's 95% of where I get my DIY education.
Backstory: SO has a post about this stove that has several people showing bad solders of one joint on a relay in the bowels of the stove (really, it took me and my son almost 2 hours to disassemble it to get to it). My video details disassembly, location, repair, and a quick reassembly. ~8 minutes of video. Sadly, people report most repair services just recommend you replace the whole stove, because replacement boards are ~$700, and you can't tell which of 3 boards until you've spent 2 hours on disassembly/reassembly. Most repair services aren't willing to re-solder a joint.
Here's the video I made, FYI: https://www.youtube.com/watch?v=dbxugIpIiS8
