LG Dryer d80, d90 and d95 Codes: Blocked Vent (Flow Sense)
Updated
Short answer
What d80, d90, d95 means
In LG's words, condensed: the dryer's duct blockage sensor has detected a blockage in the exhaust ductwork; d90 and d95 mean 90 and 95 percent blocked, prompting immediate attention (LG).
What LG says to try
- Make sure the lint filter is clean and free of blockages.
- Check the outside dryer vent while the dryer runs: there should be strong airflow. Weak or no airflow means a restriction to remove.
- Check the duct behind the dryer for kinks or crushing, and keep it short and straight.
Unplug the appliance or switch off its breaker before reaching into any part of it. Codes and steps vary by model, so check your manual too.
If the code comes back
A blocked run inside walls or a long basement run usually needs a vent cleaning service. Dryer vent cleaning costs $75 to $340; $80 to $150 for a basement or first-floor vent. (Angi, dryer vent cleaning cost (updated Jul 8, 2026))
This is also a fire-safety code: the U.S. Fire Administration names failure to clean as the leading cause of residential dryer fires (USFA), and NFPA says to keep the outside flap clear of snow (NFPA).
