LG 7.4 cu. ft. Smart Front Load Electric Dryer with AI Sensor Dry and FlowSense – White

• AI Sensor Dry™: Built-in AI technology detects fabric texture and load size, then automatically selects the optimal drying settings — temperature, motions, and time — for the most effective and fabric-safe drying result with every load.
• FlowSense® Duct Clogging Indicator: Monitors your vent duct and alerts you when airflow is reduced due to lint buildup or a clog — helping maintain peak dryer performance, extend appliance life, and reduce the risk of dryer fires.
• Lint Filter Indicator: A dedicated alert notifies you when the lint filter needs cleaning, ensuring consistent drying efficiency and safer operation with every cycle.
• 7.4 cu. ft. Ultra-Large Capacity: An extra-large drum fits a king-size comforter and large family loads in a single drying cycle, dramatically reducing the total number of dryer runs needed each week.
• Sensor Dry: Detects moisture levels inside the drum and automatically adjusts drying time to match the load — ensuring clothes come out completely dry without over-drying or shrinkage.
• Wrinkle Care Option: Periodically tumbles the load for up to 3 hours after the cycle ends to prevent creases from setting in — ideal for when you cannot unload the dryer immediately.
• ThinQ® Smart Control: Connect via the LG ThinQ® app to start, stop, and monitor drying cycles remotely, receive ThinQ Care maintenance alerts, and download new ThinQ UP™ features.
• LoDecibel™ Quiet Operation: Designed for low-noise operation so the dryer can run during naptime, in the evening, or while you are watching TV without disrupting your household.
• Speed Dry Cycle: A fast cycle that dries a small load of lightly used items quickly — ideal for last-minute laundry needs or clothes that need a quick refresh.
• ENERGY STAR® Certified: Meets EPA energy efficiency standards, using approximately 20% less energy than conventional models through high-efficiency sensor drying and low-heat settings.

Q1: What is AI Sensor Dry™ and how is it different from standard Sensor Dry?
A: Standard Sensor Dry detects moisture and adjusts drying time accordingly. AI Sensor Dry™ takes this further by also detecting fabric texture and load size at the start of the cycle, then selecting the optimal combination of drying motions, temperatures, and timing specific to that load — providing more precise, fabric-conscious drying results than standard moisture sensing alone.

Q2: What does the FlowSense® Duct Clogging Indicator do?
A: FlowSense® continuously monitors the airflow through your dryer's exhaust duct during operation. If it detects a restriction or blockage — caused by lint buildup, a kinked duct, or a clogged vent — it alerts you with a warning so you can clear the issue before it affects drying performance or creates a fire hazard.

Q3: How long does the Wrinkle Care option run after the cycle ends?
A: The Wrinkle Care option on the DLE3420W periodically tumbles your clothes without heat for up to 3 hours after the drying cycle completes. This keeps garments moving to prevent creases from setting in until you are ready to unload — especially helpful when you cannot get to the laundry immediately.

Q4: Is this dryer stackable?
A: Yes, the DLE3420W is stackable with a compatible LG front load washer using an optional LG stacking kit (such as the KSTK4), making it ideal for compact laundry rooms or closets where space is limited.

Q5: What electrical connection does this dryer require?
A: The DLE3420W requires a dedicated 240V / 30-amp circuit. A power cord is not included and must be purchased separately in either a 3-prong or 4-prong configuration to match your existing outlet.
