Product review (5 stars): Good Price & It Works
I don't know how much you can reward a fuse, but this one is affordable and it works. It is essentially a fuse encased in epoxy to prevent thermal overload in dryers. It's been running in our dryer for a while now with no problems. Very nice.

Ps. This takes some mechanical know how to install. Considering the voltage of most electric dryers, I highly recommend not replacing this part yourself if you are concerned about the ramifications of doing so.
