d80 — / d90 / d95 — Exhaust Duct Blocked

The d80, d90, and d95 codes report that the exhaust duct is 80%, 90%, or 95% blocked. They are airflow warnings, not a part failure — the dryer is telling you airflow is restricted.

How to fix it

  1. Clean the lint filter completely (and wash it if it has fabric-softener film).
  2. Disconnect and clean the vent hose behind the dryer.
  3. Clear lint from the full wall-duct run and the exterior vent flap.
  4. Run a cycle — the code should clear once airflow is restored.
