They can break in use.
I am a teacher and I have tried so many different pencil sharpeners and I must say that the quietest is the Classroom Friendly Pencil Sharpener. It is a manual sharpener with a self feeding feature. It also has an automatic stop so that you never over sharpen. I wish I discovered this sharpener years ago. You can take a look at www.classroomfriendlysupplies.com

The blower in my 2001 Honda Civic did not stop working.
More thank likely a blown fuse.
Check for a spot of corrosion!
