Richard M Jupiter , FL August 14, 2015 Appliance: Model DLEX3470V No error codes but dryer kept running after timer was at zero dryer control panel lit but even when cycle was over would not shut down dryer Replaced main control board (pcb assembly). Removed top of dryer, took a cell phone picture of how wire connectors were connected and removed old board. New board was a breeze to put in. Whole repair took less than an hour and that was with cleaning up the area behind the dryer. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
