I’ve spent an hour Googling this but can’t find any previous posts that match my problem: the “grate” [I believe that’s what it’s called - the vent inside the dryer] is leaving black, crusty burn marks on clothes. The burns are patterned identical to this vent with small circles on them, and it’s only athletic clothes [Nike, Under Armour, etc] and fleece clothing that end up with the burns; jeans and cotton clothes come out fine. I regularly clean the lint trap, never overstuff the dryer, and always dry the clothes on “normal” and adjust the heat to “low.” We bought the dryer brand new in August 2018. There is zero burning smell, and the “good airflow” light stays green throughout the entire cycle, so I’m really at a loss here on what could be causing this. Any input would be much appreciated, thank you!
