How to Fix Maytag Dryer Error d16

Error Code: Dryer Difficulty: Easy

Problem: Diagnostic code: Moisture sensor circuit failure or communication error

How to Fix Dryer Error

1. Enter diagnostic mode and run moisture sensor test—observe resistance reading with dry vs. damp cloth on sensor bars.
2. Unplug dryer and open door to locate moisture sensor bars inside drum opening.
3. Clean bars thoroughly with isopropyl alcohol to remove fabric softener residue.
4. Remove front lower panel to access sensor wiring harness connection at control board.
5. Disconnect harness and inspect terminals for corrosion—clean with electronic contact cleaner if needed.
6. Measure resistance across sensor terminals at board—should read 1-2 megohms when dry. Near-zero resistance indicates shorted sensors.
7. If cleaning and reseating connections doesn’t resolve issue, replace moisture sensor assembly WPW
8. Route new harness carefully avoiding pinch points near drum rotation path.
9. Reconnect to control board ensuring secure connection.
10. Exit diagnostic mode and clear fault history per service manual procedure. Run test load with damp towels to verify sensor extends drying time appropriately.
