LG TROMM DLE7177RM Dryer: when I turn power on it says clean filter, filter is clean. when I select settings and turn dryer on it says simultaneously "DRY" flashing and "COOLING" on -- it ends up taking about 3 hours to dry a load. I've read the manual but can't find anywhere what this could be. Any help would be appreciated.
