LG DLEX4000B d80 error code
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
- Lint filter needs cleaning
- Exhaust duct is crushed, long, blocked, or clogged
- Outside vent hood is blocked
- Load or cycle choice is preventing normal drying
Manual-backed fix steps
- Clean the lint filter before testing again.
- Inspect the exhaust duct and exterior vent for lint buildup or restriction.
- Reduce oversized loads and select a suitable drying cycle.
- Stop using the dryer and request service if airflow warnings remain after venting is corrected.
