I wasn't sure what the problem was, but the most obvious and inexpensive items to replace were the igniter, coil kit and flame sensor. I bought all of these for less than a service charge from a repair company. Replacing these parts took less than 15 minutes. I'm still not sure which item was faulty, but the dryer works great again.
