Dryer would not heat up

First I removed two screws holding a bracket that keeps the two ignition coils in place and removed the wires to the two coils. I replaced the old coils with the new coils, re-attached the wires and re-secured the bracket. I also replace the door catch simply using a flat head screw driver to remove the broken catch and pushed in the new catch. The Lint Screen is a simple replacement requiring no tools.
