Product review (4 stars): Part works great. Excellent value.
Short version:
Part works great. Excellent value.

Longer version:
  I was wary of some after-market versions (for this thermofuse part) that were listed on the web - especially, after reading some reviews of others. In particular, one review cited an after-market version which had no labeling or stenciling on the part. The listing for this particular product identified the manufacturer of the part, which I found more reassuring; so I ordered it. (Ordered item cost factors less than the part via OEMs; worth a gamble.)
  The part arrived very quickly; free shipping too. Part arrived (safely and intact) in a bubble pack envelope; it was inside a plastic bag with a sticker listing the part number. Closer inspection found the part# appearing as raised lettering on the plastic portion of the part. (Another reassuring discovery, although it was difficult to read the raised lettering on white plastic. I rubbed a graphite pencil lead across the raised lettering ... in the (very) remote chance that someone might need to be able to read that part# again.)
  The next reassuring factor was the installation of the part; it slid into place smoothly and then the securing fastener was easily installed.
  Final reassuring factor (after putting on the back cover of the dryer and reconnecting the vent and power supply) was pushing the "start" button ... and the dryer started up. Hooray! (The original/prior blown thermofuse had disabled the circuit for the drive motor of the clothes dryer.)
  A happy ending; part revitalized our geriatric clothes dryer (again). (It is over 30 years old; have had to replace a number of wear / maintenance parts, but the fundamental parts are still the original parts.)
