Possible Causes

Oversized unit for small room, Faulty humidity sensor causing rapid on/off, Overheating compressor or fan, Incorrect placement near humidity source

How to Fix / Troubleshooting

Safety: Unplug the unit before moving or opening it.

  • Placement: Move the dehumidifier to a more central location away from direct moisture sources (like a bathroom door) and away from cold drafts.
  • Check humidity setting: Set the target humidity to a reasonable level (e.g., 50–55%) to avoid rapid cycling.
  • Clean filter and coils: Ensure good airflow to prevent overheating.
  • Humidity sensor: If the unit cycles even when humidity is stable, inspect and replace the humidity sensor module.
  • Compressor protection: Persistent short cycling with hot compressor may indicate a failing compressor or overload protector; consult a technician.
