Sounds like you either have a loose connection or a bad dimmer. Unless you have a short to ground or excessive amp draw, a fuse will not blow. Circuit breakers trip. That should be a 15 amp fuse. If higher amp, then that may be why it didn't blow/burn. Pull the switch from the wall and see what happened.
