Product review (5 stars): it worked
The dryer stopped working, and luckily I found the service instruction sheet tucked away inside its guts.  As a result,  I was able to determine where exactly the fuse was located in the machine (not obvious at all), how to remove it, and how to continuity test it to confirm blown condition.  So I bought this part and replaced the old one.  Now the dryer works the way it did before.  Phew - disaster avoided.

Low cost fix - check.  Didn't have to call "the guy": check.  Chalk this one up in the win column.
