Besides, it complicates the transformer winding process and leads to early transformer failure if the thermal fuse is located other than the outer part. Remove the copper shield and look for the bulge on the primary side, the thermal fuse is usually inside a fiberglass tubing. The transformer bobbin might have separate sections for the primary and secondary windings which makes servicing easier. The transformer is already broken so why not open the thing? You got nothing to loose at this point.
I'll try to open (???) the transformer to see where is the thermal fuse...
