Tank,

If yours is like mine and you're setting your temp wheel to MIN to achieve recirculate, you're still getting 20% outside air and therefore the smell of unwanted odors still persists. The manual say to mash the "0" button when encountering bad odors.. yeah, right, then you just "burn up" inside with no air at all
