Possible Causes
Humidity sensor too close to mist outlet, Unit placed in small enclosed area, Sensor contaminated or misreading, Firmware hysteresis behavior combined with poor placement
How to Fix / Troubleshooting
Steps (unplug before internal work):
- Relocate unit: Place the humidifier in a more open area, away from walls and at least several feet from the bed or seating area.
- Adjust direction: Point the mist outlet away from the built‑in humidity sensor location so the sensor measures room air, not direct mist.
- Clean sensor: Gently clean the humidity sensor vents with a dry brush.
- Verify with external meter: Use a separate hygrometer to compare readings. If the built‑in sensor is significantly off, replace the humidity sensor module.
