Replaced the dryer heater element. Biggest issue was finding a video showing how to do it. The dryer is 10 years old, so I ended up finding one relevant video for taking removing the door unit and another for replacing the element. I would also recommend taking pics of the screws and where they came from. I ended up with 12-14 screws that all look kind of alike but centerainly have different applications, so a pic of each before I removed it would have helped.
