Solution: Remove Foot Control and see if the Salon Vac Turns on

Solution: The fuse needs to be replaced.

 A fuse is a protective device that cuts off the current if a circuit overloads or if there is a fault.  The Salon Vac comes with two fuses located within the fuse holder.

Once you open the fuse holder, and there is no replacement fuse, you can purchase a new glass cartridge fuse from a good hardware store.
