I first checked the owner's manual an on line documentation from the manufacturer on how to change the door switch on the dryer but found nothing. First step: Turn off breaker to dryer. I then popped the lid of the dryer and could see that the switch was accessible from the top. I was pleasantly surprised to see the parts arrive within 2 days with the lowest cost standard shipment. I loosened the 2 screws holding the switch, unplugged the modular clip, replaced switch, resecured with screws and dropped dryer lid back in place. Interior bulb was busted up, I removed cover plate, base and broken glass, seated replacement bulb, reattached cover and turned breaker back on. Dryer switch and bulb are working again. You sent me exactly what I needed and fast. Thanks for the quick turn around!
