Good lord. The door switch took 5 days to fix? 
LOL - Actually it took 2 days for the wife to find her Fluke meter, a day for me to test, and 2 days for me to get off my lazy ass and get to Sears for the switch.
Please tell me how you fixed it. My Dryer is only 5 years old, but I think it’s the same problem. Thanks.
A ha! Now your PM makes sense!
I pulled the switch out and my wife tested it with her fluke meter; it was open no matter what we tried so I bought a new one and replaced the old one.
If you Google your dryer you can usually find the location of the door switch and the part #. Then I just googled the part # to see who carried it.
