Veronica C San Antonio , TX October 09, 2015 Power error on samsung dryer We replaced the main control board with this piece and it works great. Much nicer to pay $100 with fast shipping on a repair that is very easy to figure out than to replace the machine or pay an appliance repair person to do it. Took a whole 5 minutes. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
