You should have power to the gray and red wires on the motor wire harness.

Most of the time if you have the correct voltage to a dryer and the motor does not run it's because of a bad thermal fuse or door switch.
Many times if the motor is bad it will still growl, hum or start hard, but you can tell it's getting voltage.

You can check the door switch and thermal fuse for continuity with a multimeter to see if they are good or not.

The MDE3000 uses thermal fuse part # 33001762.

Here is a video that will show you how to check the thermal fuse.

I've checked both thermal fuses and the door switch, they all show connectivity. No sound, nothing happens on either dryer when the start button is pressed.
voltages:
Color-Number(Position on harness)
Grey-51(4) to Red-31(5) voltage = 0 with the door open and closed or start button
Red31(5) to Blue28(2) voltage = 121V door open and closed or start button
Yellow35(6) to Blue28(2) voltage = 65V door open, 124v door closed
blue28(2) to black32/33(1) voltage  = 124v door open or closed.

AJ:
I have attached the wiring diagram I'm looking at for your Maytag MDE3000.

Would like to see what some other techs think of your voltage readings.
