Possible Causes
Humidity sensor reading too low due to placement, Sensor blocked by dust, Unit placed where airflow bypasses sensor, Faulty humidity sensor calibration
How to Fix / Troubleshooting
Safety first: Unplug the unit before cleaning sensor areas.
- 1. Relocate the unit: Move the humidifier to a more central location in the room, away from windows, doors, and direct airflow from HVAC vents.
- 2. Clean sensor vent: Locate the humidity sensor vent and gently clean it with a soft brush or compressed air.
- 3. Cross-check humidity: Use a separate hygrometer to compare room humidity with the unit's display. If the unit reads much lower, the sensor may be faulty.
- 4. Use manual mode: Until the sensor is repaired, operate the unit in manual mode and monitor humidity with an external meter to avoid over-humidification.
