Default Do thermal fuses fail from old age?

Well, Bob Haller said he had 15 amp thermals, and occasional 20 amp inrush.
Why would that need to be "current split evenly"? Supposing they are
carrying 15 amps and 5 amps. What's the problem?

If the thermals are properly placed, they would both melt open when the
device overheated.

And suppose one thermal fails from old age? Then, Bob is back where he was
when he started.

I don't see the big problem.

Would it help to put two thermals, in parallel?


No. You could not guarantee that the current would split evenly
between the two thermal fuses. A more serious problem is that it
would require BOTH thermal fuses to blow in order to protect the
appliance.
