Dryer stops with clothes still damp when using automatic (sensor) cycles, but timed dry works

Safety First: Unplug the dryer before accessing internal wiring.

• Clean sensor bars: Wipe the moisture sensor bars inside the drum with rubbing alcohol to remove any residue.
• Test with different loads: Try a mixed load of towels and lighter items. Very small loads may not contact the sensor enough.
• Inspect wiring: Remove the front or lower panel and check the wires connected to the sensor bars for damage or disconnection.
• Continuity test: Test the sensor circuit for continuity through the bars. Repair or replace the sensor assembly if open.
• Control check: If the sensor and wiring are good but auto cycles still end too soon, the main control may be misreading sensor input and could require replacement.
