Dehumidifier’s humidistat reading is inaccurate compared to other hygrometers.

Steps:

• Compare readings: Place an independent hygrometer several feet away from the unit and compare readings.
• Adjust setpoint: Compensate for minor inaccuracies by adjusting the setpoint (e.g., set 5–10% lower than desired if the unit reads high).
• Clean sensor area: Clean the intake and around the humidity sensor to remove dust.
• Relocate unit: Avoid placing the unit where its warm exhaust air blows directly onto the sensor.
• Replace sensor: For large discrepancies, replace the humidity sensor with a Frigidaire-compatible part.
