I'm having a weird problem with my dryer. I am getting most of the lint
showing up on the correct side of the lint filter, but I am also getting
some on the wrong side of the filter, almost like a 'backwash' of air is
pushing some lint back towards the dryer. This has happened since I've
moved. It's a new house so I'm assuming the duct work is clear (no long
term accumulation of lint).
Don't assume anything. There could be anything from a crushed pipe to
an empty soda can in that duct.
How long is the pipe and can you get to all of it to see?
You could suck a ball of paper on a string through the pipe with a
vacuum to see if it is open, then pull something like a tennis ball or
softball sized wiffle ball through to be sure it is unobstructed.
Make sure you have a string attached at both ends so you can retrieve
it if it does get stuck.
I have seen this twice as a Certified Dryer Exhaust Technician, and
both times it was crushed duct work that created 'back pressure'.
