Code D80
low severity
GE models: The lint screen is in the door opening. The thermal fuse on GE dryers is mounted on the exhaust housing inside the rear panel. GE Profile and Café dryers have additional moisture-sensor bars in the drum that can be cleaned with rubbing alcohol when drying performance degrades.
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.
