Hi, thanks for using JustAnswer.com. I am not seeing a second question. I suspect the heating element has shorted to ground and is heating up without the motor running. The excess heat has caused the thermal fuse to open. Remove the back cover and let me know once you have access to the rear components. BE SURE TO UNPLUG THE DRYER FIRTS!
Okay, great! By the blower housing where the air blows out is a rectangular, white, plastic thermal fuse with blue wires going to it. WITH THE DRYER UNPLUGGED, remove those wires and tape them together. See if the machine starts. If it does, stop it and unplug again.
