Are you getting a D80 error on your LG Dryer and there is no blockage then you can follow this detailed guide to fix this error and understand this error. If your LG dryer displays the "D80" error code despite no blockage, troubleshooting steps can resolve the issue. Firstly, ensure the lint filter is clean and properly installed. Check the exhaust vent for any obstructions, ensuring it's clear of lint buildup. Next, examine the ductwork for bends or kinks that could restrict airflow. Verify that the dryer is not overloaded, as this can impede proper drying. Reset the dryer by unplugging it for a few minutes before plugging it back in. If the error persists, consider contacting LG customer support or a professional technician for further assistance.
