Dehumidifier shows incorrect humidity readings (e.g., 30% in a very damp room)

Steps to correct humidity reading:

• Verify with external meter: Use a separate hygrometer to compare actual humidity to the dehumidifier's display.
• Clean intake: Ensure the air filter and intake grille are clean so the sensor samples room air properly.
• Check sensor location: Make sure the humidity sensor is not pressed against the coil or cabinet wall; it should be in the airflow path.
• Replace sensor: If readings are consistently off by a large margin, replace the humidity sensor module.
• Control board: If a new sensor does not fix the issue, the main control board may be misreading the sensor and should be replaced.
