Well, I indeed haven't looked inside a dryer, but I am aware that dryers can burn while running. Indeed, as I just learned, they are #1 cause for house fires in Germany, and insurers will usually not pay if you let them run unsupervised. But burning while being turned off, powering some 5V circuit board... yes, it happens, but 75 times a year? But maybe that 'being turned off' was an outlier and most others were actually running.
