Error Code: Dryer Difficulty: Easy
Problem: Moisture sensor failure—five consecutive loads dried without moisture detection
How to Fix Dryer Error
- Unplug dryer and open door.
- Locate two parallel stainless steel moisture sensor bars inside drum opening near lint filter.
- Clean bars thoroughly with isopropyl alcohol and non-abrasive cloth—remove all fabric softener buildup, lint, and residue.
- Inspect for physical damage to bars or foreign objects (coins, safety pins) bridging the gap causing short circuit.
- Remove front lower panel to access sensor wiring harness connection at control board.
- Disconnect harness and measure resistance across terminals—should read 1-2 megohms when dry. Near-zero resistance indicates shorted sensors.
- If cleaning doesn’t resolve issue, replace moisture sensor assembly WPW
- Route new harness carefully avoiding pinch points near drum rotation path.
- Reconnect to control board ensuring secure connection.
- Power on and press POWER button to clear error code. Run test load with damp towels to verify sensor operation—cycle should extend drying time appropriately.
