Product review (5 stars): I hate these things
It is a fuse and it fixed the problem.  It was easy to get, arrived fast.  The price was very good compared to elsewhere.

These things seem to open to often.  I think that is a design flaw in the appliance not a problem with the part.  From what I understand they are sensitive to heat not just current.

I had one of these constantly going out on an oven.  Whirlpool changed the installation requirements because of me and modified my oven to make it work in my installation (bigger fan).  That was all in warranty.

I used this on a dishwasher.  It was very difficult to identify on the diagram as a fuse.  But it was very easy to identify that it was a problem with a VOM.  Once you know it's a fuse hot on one side and cold on the other = bad.

I think the issue with the dishwasher was I stopped it in the middle of a cycle when it was hot and on restart the combination of warm environment and startup current surge caused it to blow.
