Possible Causes

Dirty or coated moisture sensor bars, Broken moisture sensor wiring, Faulty moisture sensor module, Poor grounding of drum

How to Fix / Troubleshooting

Safety first: Unplug the dryer before cleaning internal components.

  • Clean sensor bars: Inside the drum, locate the two metal moisture sensor strips (usually near the lint filter opening). Clean them thoroughly with a soft cloth and a bit of white vinegar or mild detergent to remove fabric softener residue.
  • Check wiring: Access the back of the sensor bars from behind the front panel. Ensure the wires are securely attached and not broken.
  • Inspect for damage: Replace the sensor bars if they are physically damaged or heavily corroded.
  • Test in timed mode: Run a timed (non-sensor) cycle. If the dryer works normally, the issue is likely limited to the moisture sensing circuit.
