This is a venting / airflow code. Codes and wording can vary by model, so check your owner's manual for your model number.

How to fix LG dryer error code d80 (safe owner checks)

Safety first: disconnect power before you remove any panel or reach into the sump or drum. Do not touch wiring, the control board or the motor. If you see water near electrical parts, stop and call a technician. These steps are based on LG's published guidance [1], rewritten for clarity.

Clean the lint filter. Remove lint every load, and wash the tray with warm water and a soft brush. Let it dry before refitting.
Lighten the load. Reduce the load size so air can pass through.
Check behind the dryer. Make sure the exhaust hose isn't crushed, kinked, coiled, holed or loosely connected.
Check outside. Make sure the exhaust flaps open fully (watch them during Air Dry) and remove visible lint.
Inside the walls. If it persists, have a dryer duct cleaner clean the house vents and report the run length and number of 90° bends.
