LG DLEX4000B d80 error code

Error code: d80

d80 indicates restricted dryer airflow. LG dryer guidance treats airflow restriction as a lint, duct, venting, or installation issue to resolve before continued drying.

Common causes

Fix steps

  1. Clean the lint filter before testing again.
  2. Inspect the exhaust duct and exterior vent for lint buildup or restriction.
  3. Reduce oversized loads and select a suitable drying cycle.
  4. Stop using the dryer and request service if airflow warnings remain after venting is corrected.
