Product review (5 stars): Ordered from Appliance Parts US  A 339392 Whirlpool Dryer Lint Screen
My old original lint screen was falling apart.  I called around locally and got a sticker shocked at their price.  I  paid  a total of $16.50 (shipping included) This was a perfect fit in my Roper Dryer.  No more lint worries.  Excellent price and fast shipping.
