Oh, that makes more sense. The heat from the malfunctioning cooker may have resoldered these points badly.

I was curious how like half the points were bad, and that explains it.

That’d be about right. There’s insulation inbetween.

Unlikely any heat from the slow cooker did anything. Solder melts at 370F. A slow cooker is never going to get anywhere close to that hot.

  Strange that all the bad points are in the lower half of the board, and that most points in that half are bad, then.

    It’s most likely that it’s related to the original manufacturing. These will be machine wave-soldered, not hand soldered, and having quality vary across the board isn’t impossible if the setup/operators were less than ideal.

    Perhaps. It still seems odd to me that this board was mounted vertically inline with the heating element and the bad parts I identified line up with that, before I knew that was the case:
