I removed the top and back of the dryer to get to the drum. Removed it to replace all rollers, drum belt and tensioner. I pulled off the old felt seals, sanded surface with an electric drill and 3 inch scuz wheel down to the white paint. Wiped the area with brake clean and let dry. Followed the directions on the tube of adhesive and reglued new felt seals. Reassembled dryer and it works fine at this time. While the repair process is going on, I took the opportunity to vacuum out all the lint and dirt to prevent a fire.. All is good.
