Product review (4 stars): Dryer design flaw...this can be the fix...
There is a design flaw in many of these dryers.
A screw in the interior assembly extends into the filter area.  It catches on the felt gasket and tears it loose from the frame.  This gap allows excess lint to get past the filter.  This can lead to lint build up in the ducting (fire danger).
THE FIX:  use high temp epoxy to reinforce the bottom third of the frame to filter connection.  (Remember kids, this is a higher temperature location!)  The epoxy is used like caulk between the felt and the plastic.  Don't get it on the felt away from the frame or you can stiffen the gasket and it won't work (like the one you are probably replacing).
The expectation is that we have solved both the problem and the symptom.
Or the filter is cheap enough...you can buy a new one every year or so.
