We've had this dryer since 1/2006 and it's gradually taking longer and longer to dry, to the point that none of the non-high heat sensing cycles gets the clothes more than damp, even with the "more dry" option. The timed cycles do still work but are also taking longer and longer - a good 80-85 minutes for full-but-not-stuffed load of regular fairly lightweight clothes (t shirts, etc). I have cleaned out the dryer vent to the outside fairly regularly and that doesn't really help. I recently looked around the bottom of the inside of the dryer when I disconnected the vent and didn't see any lint build up. I also cleaned off the little sensor bars on the inside and am fanatical about cleaning the lint trap. I have never used fabric softener or dryer sheets. I have 3 small children and do a LOT of laundry - 10-14 loads a week for the last 5 years. I found the video on dissembling the duet/he3 dryer, should I take off the front panel and see if there's a secret stash of lint clogging things up? Anything else I can test? We have multimeters, etc already.
