The Switch might be going bad. Unfortunately, unless you have solder experience, replacing the switch would be difficult. Only other thing I could think of is dust/gunk build up around the motor, does the motor feel hot when the device is on setting 1? If YES: then the fan is still on and again best thing I can say it to try and clean around the motor and put some wd-40 around the gears (make sure its unplugged when you do this) and try not to get any of the wd-40 on any of the electrical components. If NO: then the switch is faulty and is turning the fan off when on the 1 setting. it will need to be replaced.
