Humidifier function disabled, F1 shown on display (on combo humidifier/dehumidifier models)

Safety: Unplug the Camry humidifier/dehumidifier combo before servicing the water system.

Steps:

• 1. Check water level: Remove the humidifier tank or reservoir and fill it to the indicated level with clean water. Reinstall securely.
• 2. Inspect float: Locate the float inside the humidifier reservoir. Ensure it moves freely and is not coated with scale or slime. Clean with a soft brush and mild detergent, then rinse.
• 3. Test level sensor: Access the internal humidifier water level sensor or float switch. Manually move the float and listen for a click or use a multimeter to verify continuity changes.
• 4. Check wiring: Follow the sensor wires to the control PCB. Reseat the connector and inspect for damage.
• 5. Replace sensor: If the switch or sensor does not operate electrically, replace it with the correct Camry humidifier level sensor for your model.

Tip: Use filtered or low-mineral water to reduce scale buildup on floats and sensors.
