Gas burner would not ignite

(I knew the gas coils were bad, since the gas ignitor would glow brightly as the burner attempted to ignite. So I knew everything except the gas valve was operating normally.)

Unplug the electrical cord to the dryer. Remove the front access panel. Remove the retainer clip for the gas coils (2 screws). Remove the coils and unplug the electrical connections. Connect the new coils to their respective electricl connections. Slide the nes coils back onto their respective posts on the gas valve. Replace the retainer clip, and 2 screws to hold it in place. (I then plugged the dryer back into the wall outlet to visually check the burner operation) Everything worked fine so I then replaced the front panel.
