Possible Causes

Dirty or coated moisture sensor bars, Loose sensor wiring, Faulty moisture sensor module, Poor drum contact with sensor due to small loads

How to Fix / Troubleshooting

Safety first: Unplug the dryer before accessing sensor wiring.

Automatic cycles rely on accurate moisture sensing.

  • Clean sensor bars: Inside the drum, locate the metal sensor strips and clean them thoroughly with a cloth and white vinegar or mild detergent. Remove all residue.
  • Avoid dryer sheets: Fabric softener sheets can coat the sensors. Reduce or eliminate their use, or clean sensors regularly.
  • Check wiring: Access the back of the sensor bars and ensure the wires are firmly connected and not corroded.
  • Load size: Very small loads may not make consistent contact with the sensors. Add a few extra items or use timed dry for very small loads.
