I was able to determine the part # for the door catch by downloading the parts list (W10194548-Rev A) online. AppliancePartsPros.com had an install video for the door latch on the part (279570 - a replacement part from the parts list) page (http://www.appliancepartspros.com/repair-help/whirlpool-dryer-wed9200sq1-repair/wed9200sq1-lid-or-door-wont-close.html), but it was for a metal one piece door. My dryer is a round metal and glass door. The door has an inner and outer door assembly. From the parts list it was difficult to determine how to separate the parts to get to the door latch. Dixie in customer service suggested reading a "Door Reversal" repair pdf file she sent me. I discovered that AppliancePartsPros.com had a You Tube install video for door reversal on a similar model (https://www.youtube.com/watch?v=H5I7IghMuvE). After removing the door at the hinges, the video showed which 6 screws needed to be removed to separate the inner and outer doors. The repair took about 10 minutes with the help of the 2 videos. I ordered the part on Thursday afternoon, and had it the next day by noon with regular shipping. I highly recommend AppliancePartsPros.com and will use them again for any future appliance repair. Thanks again, Dixie!
