LG Dryer d80, d90, or d95 in a New-Build Home: Check the House Vent Before the Dryer

On LG dryers, d80, d90, and d95 are airflow-restriction messages, with the number indicating an approximately 80%, 90%, or 95% restriction; LG also notes that d80 on a gas dryer can indicate insufficient gas supply. Because this dryer was installed in a new-build home, a clean lint filter and undamaged short transition hose do not clear the house-side vent: the wall duct, construction debris, excessive length or bends, and exterior hood are installation-handoff checks.
