Did the motor get hot/very warm? If it did, have you left it off long enough to cool. Most small motors are internally protected (impedance protected). Since the other fan is running I doubt a fuse is the problem. I have a fan I need to replace on the passenger side, bearing getting dry. When the fans are first turned on we have to spin the fan with something that will fit through the guard.
