Short Cycling Due to Sensor Placement or Settings
Unit frequently switches between dehumidify and standby even though room is still damp.

Possible Causes
Humidity sensor too close to outlet air, set humidity too high, unit placed in confined space causing recirculation, sensor drift
How to Fix / Troubleshooting
Safety: No internal work required for basic adjustments.
Steps:
- Placement: Move the unit away from walls and corners so it can sample room air, not just its own dry exhaust.
- Settings: Lower the target humidity (e.g., to 50–55%) so the unit runs longer.
- Sensor: If behavior persists, have a technician inspect and possibly relocate or replace the humidity sensor assembly.
