I took a chance and ordered the rotary start switch first . I did not have a meter here to check so I gambled on that one . After getting that piece on I realized the only other thing had to be the door switch . The part got here in one day and I got it on quick and the dryer works good .You guys are very helpful and the videos got me the access to the dryer I needed . You saved us quite a bit on a service call and I am appreciative of your help . I will definitely recommend you to anyone ...John Frerker
