How to Fix / Troubleshooting
Safety warning: If you smell burning plastic or see smoke, immediately unplug the unit and do not continue using it until inspected.
Steps:
- Initial use: A slight odor may be normal during first use as manufacturing residues burn off. This should dissipate after a few hours.
- Check vents and fan: Ensure all vents are clear and the fan operates. If the fan is not running, replace the Argo humidifier fan motor.
- Inspect PCB: Open the base and look for burnt components or discoloration on the Argo humidifier control PCB. Replace if damaged.
- Heater element: For warm-mist models, inspect the heater element for heavy scale or scorching. Replace the Argo humidifier heater element if damaged.
