If you have not given up yet. I think your heating element is open?
If you got 120VAC ( with one probe to ground ) on each side of your heating element, that tells me your AC circuit is complete.
Now measure your heating element by unplugging your dryer from 220 AC outlet.
Put your multimeter to resistance X1, and measure across were you measured the 220. You should get zero or a very low resistance. If you measure the same as if your two meter probes were not touching each other, than your heating element is open. You can measure different parts of the coil until you find the break.
I bet you it is between one of the stand offs.
Good luck.
