The LG DLEX3900W is a premium front-load electric dryer designed for modern homes where laundry needs to be efficient, quiet, and feature-packed. With a generous 7.4 cubic foot capacity, advanced sensor dry technology, and innovative steam cycles, it's built to handle everything from bulky towels to delicates. In our hands-on evaluation, it earned an overall score of 74/100, excelling in key areas like drying performance on cottons and user-friendly controls—but falling short on energy efficiency and cycle speed.

The DLEX3900W truly impresses on cotton loads, achieving a perfect 5/5 score with very dry results after the max cycle—no damp spots or uneven patches on towels or jeans. Permanent press cycles score 4/5, delivering very good wrinkle reduction that's ideal for shirts and blends. However, expect longer run times: the normal cycle clocks in at 120 minutes, about 25-30% slower than average (90-100 minutes). This is due to its precise sensor dry system, which prioritizes fabric care over speed.
In tests, it left loads bone-dry without scorching, and the stainless steel interior resisted wear after 50+ cycles. Auto temperature control with 5 settings ensures versatility for synthetics to heavy cottons.
Earning a flawless 5/5, this dryer's features feel premium: steam cycles for sanitizing and refreshing clothes (great for gym gear or musty items), smartphone app for remote monitoring and diagnostics, delay start up to 19 hours, and stackable design with reversible door. The touch-pad controls are intuitive, with drum light, lint filter reminder, and exterior pocket handle for easy access. At 38.7 x 27 x 29.9 inches and 136 lbs, it fits standard closets but needs pro install for venting.
Pro Tip: Use steam refresh to cut ironing time by 50% on lightly wrinkled loads.

At 5/5 for noise, it's one of the quietest we've tested—operating at under 60 decibels, like a soft conversation. Perfect for apartments or open floor plans. The 1-year warranty covers parts/labor, but predicted reliability is middling at 3/5, so consider extended coverage.
