Turn the fan off. The middle knob of the controls has a setting below 1 that operates the fan at varying speeds if it is set in between 1 and off. If that's not it then hopefully somebody else will know what it is.

it could be the final stage resistor pack (the sword) it could be shorted try turning on the fan on high and then back one notch at a time if the fan speed does not change then this is the problem

The fan speed does not change, so I think that is my problem where is this "final stage resistor pack (the sword)"? Is it similar to a fuse or what Can some one tell me what the heck it is? Thanx
