Ryan A Antioch , IL May 11, 2025 Appliance: LG Dryer DLG3401W/00 Lg Dryer Dlg3401w/00: Sensor was inop. How to replace Dryer Moisture Sensor Bar. Very easy fix. Took 20 minutes to remove only because you were halfway into the tub in reverse. The new part install was about 15 minutes because I took the time to clean everything.
