Maytag Neptune Electric Dryer Model #MDE3000AYW purchased in 1999.

Worked fine in the morning, but in the afternoon but it would not start.

1. It has power.
2. The door switch works.
3. I suspected the push-to-start switch, so I opened up the rear top panel and got my voltage tester out and I have 120V to the red wires on one side of the switch.
4. I disconnected the switch and put my continuity tester on each contact. I have continuity between the two contacts when I hold the button down, but no continuity when I release the button.
5. I reconnected the switch and jumpered the two red wires that connect to contact #1 to the yellow wire that connect to contact #2. Still won't start.

Is that normal behavior?
Are there any other tests I can try?
Could it be the Drive Motor?
