Dehumidifier shuts off after a short time even though the room is still humid.

Safety first: Unplug before moving or opening the unit.

• Check settings: Verify the humidity setpoint is low enough (e.g., 40–50%). Increase fan speed if selectable.
• Relocate unit: Move the dehumidifier to a more central location away from walls and corners so the sensor measures room air, not just discharge air.
• Inspect humidity sensor: Ensure the sensor is not blocked by dust or objects. Clean gently with dry air.
• Compare with hygrometer: If the displayed humidity is much lower than actual, replace the humidity sensor module.
