Kevin R:
The automatically resetting thermal bi-metal cutout or "thermostat" is what
Sam Goldwasser was referring to here.

Martik:
As the James Sweet reply post correctly suggested, install the l67C
lower temperature rated thermal fuse.
As with any fuse, NEVER substitute a higher value than the OEM value or
bypass it, it is there for a very good safety reason... it is not
worth the risk; if you do you are literally playing with fire.

And, if it blows again, toss the dryer. A second failrue would almost
certainly NOT be because the fuse is a few degrees too low. Something
else is intermittent or has failed completely like the thermostat.

what hair dryer has a thermostat? none of the ones I have worked on, the
different temperature settings are usually done by putting the heaters in
different combination series /parallel and shorting out sections, speed
of
the motor is also done by putting a low voltage motor across different
amounts of the heater element, usually you have a thermal bi metal cut out
backed up by a thermal fuse, if the thermal fuse goes I would look for a
stuck cut out and a blocked intake grill
