That style would require two thermal fuses. One on top and one on the
warmer. I couldn't find anyone selling internal repair parts that
might also have an exploded view showing the fuses.

Looks like it has a 3 year warranty. Find your receipt.
Support 1-800-352-2866. Call and ask.

The two thermal series connected fuses are both located side by side on
top of the heated water tank.

Well, that's the most likely to overheat, but it certainly would not
require two fuses to do the job. Something is wrong here.

There was no accessable thermal fuse I could see located on the warmer
heater, but maybe one was buried inside it.

Maybe, but more likely the factory forgot to install one on the
warmer. So they put it where it would fit easily, which is next to
the upper heater fuse. QA? Whazzat?
