I hate working on these Fragramatics vacuums. The vacuums have 6 special screws to unlock the top and everything is just so crammed in there. One of the vacuum motors was not working so I had to remove the motor to check the brushes. The brushes were fine but a fuse was blown. I will check the fuse first next time. Even though 2 out of the 3 motors worked, you can still tell there is a problem.
