I am confused by "roaring." Sounds like the fan is moving air like it's supposed to. Is it whining like something is rubbing against the blades? Is it squealing? If not, it's probably OK.

It is easy to pull the cover off the cowl. Probably worth doing to mak sure everything is clear and to clean out the drains at the front on both sides of the blower.

To remove the blower:

- remove the top cover
- unplug the cable to the resistors and remove the resistor pack (2 screws)
- soak the nuts at each corner of the blower with PB Blaster and go to bed
- next day, remove the four nuts and lift the blower out. You do not want to snap the bottom bolts.

BTW - George Murphy has rebuilt motors and even new brushes for 25 bucks which will save you a ton of money if your motor dies (george_murphy@compuserve.com)
