Dryer stops early and clothes are still damp, but the display shows the cycle as finished.

Safety first: Unplug the dryer before cleaning sensor bars.

Step-by-step checks:

• Clean sensor bars: Wipe the metal moisture sensor strips inside the drum with a cloth dampened with white vinegar to remove residues.
• Adjust load size: Avoid running very small loads on sensor programs; use timed dry instead or add a few extra items.
• Test on timed program: If timed drying works correctly, the issue is likely with the sensor system rather than heating.

When to call a technician: Persistent premature stopping despite clean sensors may require sensor or PCB replacement.
