GE dryer runs but takes too long to dry clothes. Loads are warm but still damp at end of cycle.

Safety first: Unplug the dryer before disconnecting the vent.

Restore airflow:

• Clean the lint filter thoroughly, including washing with warm water if coated with residue.
• Disconnect the vent hose and check for lint buildup, kinks, or crushing; clean or replace as needed.
• Inspect and clean the wall or roof vent cap.
• Run a test load with the vent disconnected (temporarily, in a well-ventilated area) to see if drying improves; if so, the vent system needs further cleaning or redesign.

Check moisture sensor:

• Clean the moisture sensor bars inside the drum with rubbing alcohol to remove dryer sheet residue.

If drying is still poor with good airflow and clean sensors, further diagnosis of heater output and control operation is needed.
