Dryer
Code D80
high severity
Samsung models: The lint filter sits in the door opening on all Samsung DV series dryers. The exhaust duct exits at the lower-rear. Samsung's Vent Sensor actively measures airflow restriction throughout the cycle and directly generates D80/D90 readings when blockage reaches threshold.
Common causes
- Lint trap full and not cleaned between cycles
- Vent duct partially blocked by lint accumulation
- Vent duct kinked, crushed, or too long
- Bird nest or external debris blocking the exterior vent cap
Step-by-step fix
- Clean the lint trap completely — even a thin film of dryer-sheet residue reduces airflow significantly.
- Disconnect the duct at the back of the dryer and vacuum it out from both ends.
- Check the exterior vent cap and clear any obstruction.
- Ensure the duct run is as short and straight as possible — each 90° bend is equivalent to adding several feet of length.

Prevention
- Clean the lint trap before every load.
- Clean the vent duct at least once a year.
- Use rigid or semi-rigid metal duct, never plastic flex duct.
When to stop DIY
Call a professional duct-cleaning service if the duct is very long, built into the wall, or shows damage.
