Product review (5 stars): Install both parts!
Be sure to install both parts. I'm a novice home improvement diy'er and I tested all the parts and found only the fuse faulty. When I received my parts it had both parts. I only installed the part that I knew was bad and within two loads the fuse shorted again. I learned my lesson. I bought the parts again, installed both, and the dryer has been working perfectly for weeks.
