Dehumidifier cycles on and off rapidly when set to a specific humidity

Safety first: Unplug the unit before moving or opening it.

Steps to reduce rapid cycling:

• Relocate unit: Move the dehumidifier away from corners, vents, or direct airflow from HVAC registers.
• Change setpoint: Increase or decrease the humidity setpoint slightly to widen the effective control band.
• Sensor inspection: If accessible, ensure the humidity sensor is properly mounted near the air intake, not directly in the outlet airflow.

If cycling remains excessive, a technician may need to evaluate the control board and sensor.
