I have that model. I'm not positive this gets all areas, but in my search to get at the heating element, I went in thru the back. Unclip your vent hose, unscrew that plate around it (near bttm. of dryer on back), and reach in - hand, duster, blower - all very carefully of course, and with power off/unplugged.
There is likely more space to clean but that gets it from around motor and elec. business.
