Code H1
medium 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
- Restricted exhaust airflow causing heat buildup
- Cycling thermostat failed in the closed position
- High-limit thermostat holding open
Step-by-step fix
- Clear the vent duct completely (see D80 steps).
- Test the cycling thermostat — it should open and close as temperature changes.
- If the dryer overheats even with a clear duct, the cycling thermostat has failed and needs replacement.
