After watching your videos on replacing the trap duct, rear bearing sleeve, bearing slides and upper front bearing support the dryer is like new again. I will say the videos were a tremendous help and confidence boost. They were spot on and I really didn’t come across issues. In fact if you have any mechanical abilities it was pretty easy. Turns out the smells were years of lint buildup in the drum back vent and also in the trap duct. A good cleaning and replacing the bad trap duct assembly and no more smells.
