The video made it possible for me to accomplish this task myself, though I wish it included the footage showing the struggle that the technician had to go through to get the fan housing in and out. Trying to do that without breaking it was very challenging. I coated the exterior of the fan assembly with petroleum jelly to help me maneuver it. In addition to screwdriver and nut driver I also needed gloves, a shop light, padding to lay on, a vacuum, and brush. I also used a file on one section of the side of the drip pan to give me an extra 1/8 inch or so of room to maneuver the fan housing. The spot I filed is visible in the video at 6:13 in the lower right corner, just above the word "Appliance." Tricky job, but the video helped a lot.
