Why are my clothes still damp even though my LG dryer is drying them?

Your clothes are still damp even though your LG dryer is running because of poor airflow, insufficient heat, overloading, or sensor misreading, not because the dryer is not tumbling. The number one cause is a clogged vent system. LG dryers have sensitive d80, d90, d95 duct blockage detection. If lint builds up in the lint filter, in the housing below it, in the flexible transition duct behind the dryer, in the wall duct, or at the exterior flap, hot moist air cannot escape, so moisture stays in the drum and drying time doubles or triples. Check if the outside vent flap opens fully when dryer is running. Second, your dryer may be producing only partial heat due to a blown thermal fuse or partially failed heating element in electric models, or weak gas valve coils in gas models, causing long cool tumbles. Third, overloading prevents clothes from tumbling freely and blocks air circulation, so items in the center stay wet. Keep loads at 75 percent full. Fourth, fabric softener sheets and liquid softener coat the two metal moisture sensor bars inside the drum, causing them to incorrectly read clothes as dry and end the cycle early, leaving damp clothes. Clean sensor bars with rubbing alcohol. Also ensure you are using Sensor Dry with High heat for towels and not Energy Saver mode which uses lower heat intentionally.
