Derrell D Mount Gilead , NC July 26, 2014 Appliance: Whirlpool Washer WFW97HEXW2 Whirlpool Washer Wfw97hexw2: A power failure has occurred. How to replace Washing Machine Control Board. I have a whirlpool washer WFW97HEXW2 and it stopped working, all the blue led lights were on and didn't respond to power on or off, unplugged it over night and it started back but didn't last long. I replaced the main control board and it's working great now, also great price and fast shipping from Appliance parts pro. 9 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
