I went online to find a replacement part but couldn't order one with just the model and serial number, a part number was required. I watched a video on YouTube to see how to remove the door switch assembly to get the part number. Luckily it can be accessed from the front by removing the door seal retainer and the 3 screws holding the switch asy in place. After spending an extra 10 minutes figuring out how to remove a cover from the assembly which blocks the part number label, I had what I needed. Returning to my online search I decided to order from AppliancePartsPros.com because I felt more confident I would be getting an OEM replacement even though many sites had parts for 1/4 the price. I ordered the part on a Thursday and got it on Saturday and had our washer back together and working within 15 minutes.
