Blower wheel cracked in half

Turn circuit breaker off, unplug for added safety. Use a medium flat head screwdriver and lift the top up. Use a nut driver to remove two screws holding the front panel to the frame. Remove the front panel and begin to dismantle the blower wheel. Remove the outer clamp from hte motor shaft, then the U-clip (inexpensive plier that has to pins to open the U-clip.... tricky little bugger). Pull the blower wheel off and replace with the new wheel. Reverse the proedure and your ready to go.
