The other day I noticed my neighbor throwing out a vertical fan into the garbage. My air force electronics training makes me want to look at this. So I grabbed it and took it apart to see what the problem was. Usually these things need a spot of oil to unseize the motor. It wasn't the motor and the actual problem really surprised me. It was a blown fuse. The blown fuse didn't surprise me, it was the idea of having a fuse in a fan. Never seen that before. It was a small glass fuse and I couldn't find a replacement, so I used a larger glass fuse and hard wired it in. Worked like a charm and I have another fan.
