My 2 yr old Maytag dryer wasn't heating so I order the part and changed the heating element. The old one looked used but ok. Still won't heat up. So I used a digital miltimeter and tested the continuity on the thermal fuse, the cycling thermostat, and the high limit thermostat. They all had continuity. I'm stuck. Dont know what else to try. Anybody have suggestions. ...or a cheap, but good repair man?
