Jack L Annandale , VA April 10, 2015 Appliance: Model DDSR475ET6WW Exhaust pipe was rusted Removed front of dryer and back access plate allowing me to see that the pipe just slipped over the blower. A small tab in the back cover was inserted inside the left side of the pipe and when I straightened the tab I could move the pipe to the right and then straight out. Replacement of the pipe was the reverse. The new pipe did not have a hole for the tab, so I bent the tab to its original position, and rested the pipe against the tab. The new pipe had a rear flange that kept it in place. Last step was to replace front and back access plate. If you work on a similar model you can skip the removal of the front; I did this to see how the pipe was attached to the blower as I thought there might be bolts or screws. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
