Open dryer door. Remove four Phillip head screws that hold lint assembly together. Two inside and two on the outside. There is also a hex head screw behind the front panel. To get at it I removed the four hex heads at bottom of front panel and four star head screws on left side of front panel. I was able to get at it by pulling the front panel out as much as possible and and reaching from the side with small quarter inch socket. Remove lint assembly, vacuum out everything and replace with new piece. Hopefully this helps. The invisible hex head took me a long time to figure out.
