Humidifier continues running even after the room feels very humid or windows show condensation.

Steps:

• Check settings: Confirm the target humidity is not set too high (e.g., 70–80%). For comfort and to avoid condensation, set between 40–50%.
• Verify sensor: Compare the humidifier's reading with an external hygrometer. If the built‑in reading is much lower, the sensor may be faulty.
• Inspect sensor wiring: Unplug the unit, open the housing, and ensure the humidity sensor harness is connected securely.
• Replace sensor: Install a new humidity sensor module if readings are inaccurate.
• Control board: If the sensor is accurate but the unit ignores the setpoint, the main PCB may be defective and should be replaced.
