Possible Causes

Restricted exhaust vent, Lint buildup in lint housing or blower, Dirty moisture sensor bars, Weak heating element or cycling thermostat out of calibration

How to Fix / Troubleshooting

Safety First: Unplug the dryer before cleaning internal components.

  • Clean lint filter and housing:
    • Clean the lint screen after every load.
    • Vacuum inside the lint filter housing.
  • Inspect and clean venting:
    • Disconnect the vent hose and clean it thoroughly.
    • Clean the wall duct and outside vent hood.
  • Test with vent disconnected:
    • Run a timed dry cycle with the vent temporarily disconnected (in a safe, ventilated area).
    • If drying improves, the house vent is restricted.
  • Clean moisture sensor bars:
    • Wipe the sensor bars inside the drum with rubbing alcohol to remove residue.
  • Check heating system:
    • If airflow and sensors are good, test the heating element and cycling thermostat for proper operation and replace if weak or faulty.
