First I found a YouTube video and my husband took it apart to see what was wrong. We realized the door switch was broken. Then I searched and found the part on AppliancePartsPros.com. I bought the new part (door switch assembly) and paid to have it shipped in 2 days (I have kids and lots of laundry ??). I also watched the video on their site on how to repair it. Once it came my husband switched it out with the broken one. It took about 10 minutes to fix once we had watched the video and knew what to do.
