Dryer runs for 30 minutes and shuts off on E 64 call service code. Other posts I have read say it's a bad heating element but the dryer still heats up like normal . Would it still be the heating element or could it be something else? Problem didn't start till some lint got inside heating element and you could smell it burning I took dryer apart and clean all pint out and still shuts off on E 64 call service code.
