Never had a fuse melt itself back together. This fuse clearly popped and then the metal fused back together. Still hot when I touched it.

Harbor freight had to recall a bunch of fuses for doing just this.

Rare for sure but possible.

StoneyVI:

It could have just failed to pop, which woukd result in it heating up and melting.

Might want to check and make sure you’d not have something shorting out that’s pulling 15a+. This is the exact reason you don’t put a larger fuse in its place (they can melt) not saying you did this, but great example for why you don’t do it trying to fix the problem. Edit to add this- I almost caught a truck on fire putting a larger fuse in place of one to keep it from popping (I had a short and it would blow fuses constantly)

Task failed successfully

Don’t want to sound like a dick but it’s maybe a good time to check your fire extinguishers? Electrical problems ain’t no joke. Glad you’re okay.
