Dehumidifier display shows incorrect humidity (far from actual) but otherwise runs.

Safety: Unplug before accessing the sensor.

• Compare readings: Use a separate hygrometer to measure room humidity and compare to the unit's display.
• Clean sensor: Gently clean the humidity sensor vents with a soft brush or compressed air.
• Relocate unit: Move away from direct sunlight, heaters, or vents that can skew readings.
• Replace sensor: If readings remain off by more than ~10%, replace the "Midea humidity sensor module".
