That's exactly what I was thinking. I redid my son's dryer vent at
Thanksgiving. There was approximately 25' of flex vent from the dryer
to the outside. I replaced all but about 2' with galvanized stove pipe
(the 2' was a chunk of high quality stainles flex as opposed to the
cheap, flimsy plastic elsewhere). All that flex was troubling enough,
but checking out the inside was a revelation. I can't believe they
were getting any drying done at all, much less in three to four times
normal..

I further note that we have the Duets (electric dryer) and you should
need less drying time no matter what due to the clothes coming out of
the washer so much dryer than with a top loading agitator.

Sometimes I set my food on top when I'm transferring a load.




The repair man came the next day and the installer had pushed the dryer up
against the wall and squashed the venting stuff. As soon as the repairman
readjusted everything it worked perfectly. Whirlpool has sent me 2 emails in
response to my problem. Thanks for your help, I realize I was asking a food
prep group about an appliance that normally would not prepare food but I bet
it could pop popcorn now anyway.
