To be more specific, you'll need to completely remove the dryer's sheetmetal exhaust ducting (about 3 feet in length).
Remove the two screws that are right under the lint screen door. Then open up the back panel (around 8 screws). Under that panel, you will see the ducting coming down the back. Should be a 2 to 4 screw holding that in ... remove the duct and clean it out good! Then clean the blower fan blade that wil be exposed once the duct is removed. Have fun! Not hard to do but will take about an hour or so.
