Possible Causes

Undersized unit for room size, Excessive moisture load (leaks, open windows), Humidity sensor reading too high, Air leaks around unit placement

How to Fix / Troubleshooting

Safety: Normal operation, but check for overheating if running non-stop.

  • Reduce moisture sources: Close windows and doors, fix water leaks, and limit activities that add moisture.
  • Check room size: Ensure the dehumidifier's pint/day rating matches the room size and conditions.
  • Verify sensor accuracy: Compare with an external hygrometer. Replace humidity sensor if readings are inaccurate.
  • Improve circulation: Position the unit centrally and away from walls to improve air mixing.
