My Whirlpool Dryer does not heat... I've pulled the rear cover off and checked every sensor, switch, and fuse I could find. All were good continuity. Pull the top open and the drum out. Then I checked the wires to the igniter. It checked out good too. So now I'm not sure. When it's running you can hear a slight rattle/squeaky noise for 15 seconds then it stops with a click. Then it starts over a few minutes later.
