AFAIK, the 3010 sticker has nothing to do with the thermal
fuse issue. The thermal fuse was a debacle from the get go.
If your fuse fails, just replace it with a piece of wire. Ovens
very rarely run away. It is far more likely the fuse will fail
or its socket will corrode (can't solder it in because the solder
would melt the fuse). If the oven does run away, the heater
transistors will open up and serve as fuses.


I'd always assumed it was there to avoid heat-damage to the expensive
part (the crystal). Unfortunately, it was mounted far outside the
thermal enclosure for the crystal and its oven, so it's unlikely to
detect any failure condition short of a house fire.
