Ordered a new lint screen which was a genuine Whirlpool part. It was a perfect fit. Also cleaned dryer duct hose and vent to outside. Dryer is more efficient, clothes are more lint free and duct work is free of debris and potential fire risk. I highly recommend Annual inspection of dry lint screen, duct work and vent damper. Replace all worn parts with genuine manufacturer's parts when possible and secure all duct work with proper clamps and fasteners. Don't compromise on proper maintenance and repairs.
