first of all thank you for all the feedback and advice.. especially
about the mistake of putting in a current protection rather than a
temperature protection. I mislead myself into using a polyfuse as these
work thermally as well :( That said, 'Shera' locked immediately again
yesterday evening so the basic functionality is restored.
Oh well, I know now how to open the can and my local component supplier
has some 105degC-ish thermo switches on stock which even look very
similar to the one installed.. to be done next week :) Photos will be
updated afterwards. Some folks even advised to bridge the fuse, but I
believe that this very fuse does have its justification. At the end of
the day it's only another hour or so of work.
