How did you check the power to the dryer? A electric dryer needs 240 volts to work correctly.
If you have house hold fuse instead of breakers make sure you check the fuses for the dryer. There will be two house hold fuses and if one is bad you will still get some voltage to the dryer, but not enough for it to run correctly.
If you are sure that you have the correct voltage to the dryer then I would check #3 and #6 in this Diagram
with a ohm meter.
Here is a video that will show you how to check a thermo fuses. Your thermo fuse look a little different on your model, but they all get checked the same.
Let us know what you find.
