Opened it up (top, front, kick plate, back panel), removed the drum, blower fan, motor, and lint vent. Cleaned out everything: removed a pencil, a couple of screws, and two brassiere underwires from the bottom of the lint vent. Replaced the drum rollers and the felt seal on the back of the drum. Scraped off the old seals around the blower and the lint screen. Put it all back together with new seals. Actual time spent was pretty short, but I had to wait overnight for the glue on the felt seal to dry.
