Error Code: Dryer Difficulty: Moderate
Problem: Moisture sensor circuit failure or shorted sensor bars
How to Fix Dryer Error
- Unplug dryer and open door.
- Locate two stainless steel moisture sensor bars inside drum opening near lint filter housing.
- Clean sensor bars thoroughly with isopropyl alcohol and soft cloth—remove all fabric softener residue, lint, and debris.
- Inspect for physical damage or metal objects (coins, pins) bridging the two sensor bars causing short circuit.
- Remove front lower panel to access sensor wiring harness connection at main control board.
- Disconnect harness and measure resistance across sensor terminals at board—should read 1-2 megohms when dry. Near-zero resistance indicates shorted sensors.
- If cleaning doesn’t resolve issue and sensors show short, replace moisture sensor assembly WPW
- Route new harness carefully avoiding pinch points near drum.
- Reconnect to control board and verify secure connection.
- Run diagnostic mode (consult model-specific procedure) to test sensor operation before normal use.
