Default Do thermal fuses fail from old age?


"Larry Fishel"

I understand they work on bi-metal strips.


** Nope - that is a temperature switch.

Thermal fuses like this one use the melting point of some material and
rely
on a spring to open the circuit.


But I assume the same applies. The metal heats up and expands somewhat
when in use and contracts when not. That will eventually cause it to
fail


** Maybe so - but has nothing do with bloody bi-metal strips.
