Humidity Control / Cycling Issue
Dehumidifier short cycles; turns on and off frequently without reaching set humidity.

Possible Causes
Humidity sensor located too close to discharge air, Faulty humidity sensor, Oversized dehumidifier for room size, Control board hysteresis too narrow, Obstructed airflow causing localized readings
How to Fix / Troubleshooting
Safety first: Unplug the unit before moving or opening it.
- Relocate unit: Move the dehumidifier to a more central location in the room, away from corners and direct airflow obstructions.
- Adjust setpoint: Set the desired humidity a bit lower to reduce frequent cycling.
- Clean sensor area: Clean the humidity sensor and surrounding area to ensure accurate readings.
- Check room size: Ensure the dehumidifier capacity matches the room size. An oversized unit can reach the setpoint too quickly and cycle often.
- Sensor replacement: If cycling is extreme and humidity readings seem inaccurate, replace the humidity sensor assembly.
