Several manufacturers call for rigid metal duct, instead of the

Frigidaire, Kitchenaid, and Maytag.
It's amazing how many new installations have tried to sneak the
coiled stuff by in the wall. Damned difficult to clean out, quick to
build up lint, and so restrictive to flow. It's the old "this is the
way
we've always done it" routine.

The duct from the wall to the dryer is the flexible one. I don't know
what is inside the walls.

Frigidaire wants you to have solid duct from the machine.
Remove the tubing, clean it out, see if there's a difference.
The lint filter doesn't catch it all.
