Possible Causes

Dirty moisture sensor bars, Poor drum contact due to small load, Faulty moisture sensor wiring, Defective control moisture algorithm

How to Fix / Troubleshooting

Safety first: Turn off and unplug the dryer before any internal work.

  • Clean sensor bars: Wipe the metal moisture sensor strips inside the drum with a cloth and white vinegar to remove residues.
  • Adjust load size: Auto-dry works best with medium-sized loads. Very small loads may not contact the sensors enough; use a timed program for very small loads.
  • Check wiring: If problem persists, access the sensor connections behind the front panel and ensure wires are intact and firmly connected.
  • Control check: If cleaning and wiring are fine, the control board may misinterpret sensor signals and may need replacement.
