Product review (5 stars): but goes in easily enough. Since the dryer is 9 years old ...
The part is really small,  about 3 inches long, Arrived in a padded envelope with no problems. I had it installed at the same time as the electronic control board. The control board was a cinch, it's at the top of the dryer and pops right in. The thermofuse is UNDER the drum and difficult to access. Have tools ready! It's a little difficult to finagle the part out, but goes in easily enough. Since the dryer is 9 years old I figured it was prudent to replace the fuse as well as the electronic board, just in case. The dryer is working great!
