Adam K Tonawanda , NY December 06, 2015 Appliance: Model DV520AEP/XAC Dryer timer not counting down Spoke with Stephanie on the chat window, she was able to confirm the control board was likely defective. Ordered, shipped as promised, got my part in a few days, 15 mins later we were back drying clothes. Took the top cover off the dryer, the control board is in a metal (heat?) shield to the front-left of the unit (facing you). Pay close attention to plug the right cables / connectors / right order. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
