Thank you for the response. I guess the difference to "normal" operation is that it the noise is much much louder and it sometimes has a screeching component to it (that doesn't come out quite as it sounds in reality on the video).
Thank you so much. Really appreciate the advice. I've tried to capture the noise better in this video. It is so loud that it would be impossible to have a conversation in the laundry room. I will check the idler pulley and the belt.
The issues from the original post resolved on its own. Tonight, it startling making this noise that is only there briefly when it turns on. No change with no load vs. heavier load. Is this the idler pulley being bad?
